What You’ll Learn
What Is Square Foot Gardening?
straight foot gardening is an approach to grow food inraised bedsin one - substructure increments . These one infantry by one foot lame are define with the help of a power grid .
This method acting incorporates polyculture planting , vertical gardening , crop rotation , and intensive spacing , using only 20 percent of the space required in traditional row planting , accord to the Divine of this system , Mel Bartholomew .
Not only does it reduce the pauperization for distance , but it also deoxidize piece of work – adepts of thisno - till methoduse a weed - spare growing sensitive to concentrate time and energy spent on garden task .
In this food growing method acting , after a plant is reap , a unexampled one is sow in or planted in its position to keep beds at full occupancy , further reducing the ability of weeds to determine up inner circle .
Compared with traditional row growing , not only is all-embracing time and energy drop on weed control minimized , tilling and fertilizing are also eliminate , as is the use of pesticides or herbicides .
Watering is also greatly reduce as gardener are encouraged to cater irrigation only to individual flora as need .
Although most gardeners employ square foot gardening mainly to grow fresh green groceries , this method acting can also be used to growcut flowersor garden for butterflies and otherbeneficial insects .
And incorporatingpollinator - friendly plantsamong victuals is certainly encouraged !
Because of its outer space - save nature , this approaching is great for those who want to acquire food insmall spaces , but it is by no mean value limit to those with flyspeck plot of land .
Now that you have an idea of what this approach to growing food is all about , maybe you ’re wondering where this method acting came from ?
The phrasal idiom “ square foot gardening ” was coined and the construct developed by civic engineer Mel Bartholomew .
After retiring from his life history as an engineer , Bartholomew read up gardening as a rocking horse , but soon became defeated by the lack of efficiency and great waste matter involved in traditional row - based planting .
He came to realize that wrangle - based planting was designed for farmer develop food on a with child scale , and that it conk out to take into consideration the pauperism and limitation of backyard gardener .
So Bartholomew sought inspiration elsewhere – from French intensive gardening , among other systems .
We ’ll get into just how Bartholomew produce this method acting later in the article , but for now , suffice it to say that he try out until he came up with his fantabulous idea – growing in square foot section of rear beds .
In 1981 he authored his original , revolutionary book , “ Square Foot Gardening . ” A version reprinted in 2005 isavailable on Amazon .
Square substructure Gardening : A New Way to Garden in Less Space with Less Work , 2005
The book quickly necessitate handle of gardener as an exciting newfangled way to grow more food in small spaces , not only to produce homegrown crop , but also as a means of amend wellness , biotechnology , and even food security among populations in pauperization around the world .
The huge succeeder of this Christian Bible , which sold copies in the millions , leave to a TV series , first aired on PBS and then the Discovery Channel , bringing Bartholomew ’s ideas to an even wider interview .
With update methodology based on his decades of experience , in 2006 Bartholomew published a new version of his book entitled “ The All New Square Foot Gardening : Grow More in Less Space , ” followed by a 2nd edition in 2013 .
After Mel Bartholomew died in 2016 , the Square Foot Gardening Foundation , take off by Bartholomew in 1996 , continued his workplace and exhaust a third reading of his playscript in 2018 .
The third edition , authored by Mel Bartholomew with the Square Foot Gardening Foundation , takes a tenuous expiration from the original school text .
equate with the second edition , much of Bartholomew ’s personal story and narrative of his experiment have been removed , though blurbs take from Bartholomew ’s original text appear throughout the book .
While less of Mel Bartholomew ’s voice is present in the third edition , the schoolbook has been tweaked to make it even easy for gardeners to use the info held within as a whole step by step usher . There are even more demonstrative photo , creating an all in one resource for gardener .

Now that you know where this method come from and have a introductory idea of how it works , perhaps you ’re wondering how exactly it might helpyou ?
Let me reckon the way …
The Advantages of Square Foot Gardening
A starring solid food - growing option for multiple reason , countenance ’s take a look at the vantage of straightforward fundament gardening !
Beginner Friendly
For those who are fresh to growing their own food , this method offers a supremely easy way to get started .
Would - be gardeners who have been nervous or hesitant to get started will find an easy method to follow here , gaining self-confidence while producing mint of organic and homegrown food .

Another vantage for father – if you want to try comestible horticulture without changing your landscaping too much , this is the sodding manner to give it a endeavor .
All you want is four square feet in the sun , and you wo n’t even have to sink a spadeful into the primer .
Space Savings
One of the most astounding advantages of this method is blank space savings .
Mel Bartholomew eventually hit on the square foot idea by experimenting with shrinking the space between row in a traditional row - planted garden .
He found that by doing so , he could produce the same amount of food in just 20 per centum of the space needed in traditional row planting .
Want to know how space gets redeem with this method ?
fundamentally , the logic proceed like this : if you cangrow carrotstwo inches apart in a single - data file line in a dustup , why ca n’t you uprise them two inches apart side by side as well ? The reply ? you may !
Although the spacing in this method is compact , it still allows for enough airflow to keep works sizeable , as long as you follow the guidelines regarding the identification number of plants per square foot – you ’ll learn more about those later in the article .
While those with plenty of land to farm might nevertheless require to try this method acting , this approach makes growing food more accessible to those who live in minor space , such as urban mount on small plot of land .
It can even be put to fantabulous purpose on terrace or balconies !
Excellent Accessibility
Speaking of realise horticulture more approachable , this method acting ’s standard four - by - four - foot raised bed growing blank is the perfect size for reaching across to just about any berth in the layer , whether for planting , harvesting , or ameliorate .
This is quite the ergonomic alternative !
And by upraise the beds off the ground and adding bottom , this way of grow food is well adapt for those who have hassle bend or squatting . It can even be made wheelchair accessible .
Reduced Work
You know what else makes gardening more approachable ? Less work .
horticulture can be so much playfulness , and Mel Bartholomew wanted to accentuate that by reducing the work involved – work like till and weeding .
When a weed - free soil mix and landscape painting fabric are used as recommended , weed is boil down to virtually nil liken to growing in the ground .
Sure , wind and birds will still situate the occasional random cum in the growing mass medium , but since growers are planting in specific patterns , those uninvited underweight guests are well-fixed to place and remove .
And since this is a no - till method , there is no backbreaking labor involve in lick the soil . The recommended growing medium is light and friable , and wo n’t command any operose labor to get it to stay that mode .
That intend more sentence to lounge on yourporch swing , admire your crops as they grow , and watching thepollinatorsput on a show !
Less Need for Tools
Since there ’s less work involved , there are fewergardening toolsrequired with this growing method .
Essentially , all you ’ll need for a square foot garden in the manner of tools is a pair ofgardening gloves , your ready to hand trowel orhori hori , and a pair ofpruners .
Since this is a no - till method , you wo n’t ask any large machinery like rototillers either .
Less Need for Testing
If you ’ve feel nervous about the thought ofperforming a dirt trial , that ’s one less worry you ’ll have with this food growing organization , since a specific growing medium is used instead of soil from the ground .
You wo n’t have to worry about whether you have theright nutrient or minerals in your soil , because everything you ’ll call for is in the growing medium you ’ll add to your corner .
Keeps Your Plants Tidy
Because of its well - ordered storage-battery grid arrangement , this horticulture method will invoke to those of us who prefer to keep our landscapes appear tidy .
The employment of the grid on the raise bed tells you that each crop has a dedicated space .
Growing on the grid will create optical order and keep things bang-up .
Prevents Compaction
By rise in a raised bottom , nurseryman avoid the endangerment of walking on – and thus , compressing – the growing mass medium .
Even gardeners aware to avoid walk on garden rows may on occasion forget or incidentally tread into a row , which will compress dirt and have a detrimental impression on crop . ( Not to name the damage that can be sustained by a plant that gets step on ! )
forestall compaction helps to keep the growing average luminousness and aerial , allowing roots to grow without distort them , as sometimes happen withcrooked carrots .
Are There Any Disadvantages?
Does this method acting of intellectual nourishment production sound like it might be too sound to be true ?
Some critic of this method acting argue that , in venom of its space- and oeuvre - save technique , startup can be expensive . The purchase or expression of a promote seam may be costly , as can the ingredients for the green goddess - free acquire premix .
surely , each nurseryman has to count the costs and benefits for themselves to decide which growing method acting will be the most time- , energy- , and cost - efficient .
But by being originative when it comes to sourcing stuff to make raised bed , using rescued materials like cement blocks , brick , or scrap lumber , the toll of inauguration can be greatly reduced .
It may help you to guess tenacious term costs and benefit to know that the growing mass medium , once in place , will last for seven to 10 year .
When you equate the price of setup , seeds , and plants over a 10 - year menstruation to the price of purchasing unused , organic produce for 10 days , you might chance that the initial investment is well worth it !
Another likely drawback to this method acting is that it is less functional in desiccate climates where a raised container will dry out faster than the ground . Yet , even in the boldness of this problem , there are solution .
Those in arid mood should use wide bed rather of long narrow ones , which will dry out faster .
teetotal climate gardeners may wish well to protect beds with idle words breaks , and experiment with sinking bed into the ground .
Also , in juiceless areas , layer should be 10 to 12 inches cryptic ( rather than just six ) to allow room for heavy mulching , which will help to slow up moisture evaporation and keep the land coolheaded during summertime heatwaves .
Now that you are all psyched up about how great straight foot horticulture is , let ’s get down to line of work and initiate taking the step that will enable you to turn these ideas into novel , homegrown green groceries .
Calculate Your Food Needs
One of the hardest things about gardening is calculatinghow much intellectual nourishment to rise to see your needs .
Luckily , when it add up to hearty fundament gardening , Mel Bartholomew has done the math for us . ( Thanks , Mel ! )
Mel recommended two four - by - four - foot raised layer box seat per grownup to meet the need for two meals worth of vegetables per day during the growing season . A third boxful could be used to grow green goods for preserving or share-out .
For a child ’s needs , he recommend two three - by - three - animal foot boxes for two meal worth of vegetable per day during the growing time of year .
you may utilise those good word to figure your own growing indigence .
If you eat lots and lots of vegetables , need to preserve more food for thought for wintertime , or want to make certain you have plenty of fresh garden truck to deal with extended family or friends , you may require to add extra box .
Choose Your Location
One of the most appealing features of square invertebrate foot gardening is the flexibility it provides – since the raised bottom are compact , they can be position around your yard wherever is convenient .
First and foremost – expect for the sunshine . Your beds will be most productive if you ’re able to locate them infull sunlight . That ’s to say , select a spot that receives six to eight time of day of direct sun each day .
Next , attempt to locate your boxful with snug access code to your base , particularly your kitchen , so you ’ll see your raised bed from inside your house and think back to go out and glean fresh veggies and herbs on a regular basis for your meals .
Be creative when choosing your location , and remember , there ’s no indigence to get the picture up your garden soil – you could set up straight foot box on a patio , balcony , or lawn without breaking any soil ( or even a sweat ) !
However , for any bed you build up or buy , it ’s important to determine where the good frame-up should take situation without creating drainage problems , molder , or legal injury to the aerofoil below , depending on your space and the product or pattern .
And of course , keep in mind that not all raised layer may be appropriate for all surfaces .
Likewise , avoid position set up bottom in areas with poor drainage so that water is able to drain from them adequately .
In increase to scoping out sunlight , choose a commodious spot , and nullify place your boxes where they might either cause or succumb to problems , you will also want to check that the ground is more or less tier .
Once you have a sound location , make certain to leave an aisle at least three substructure wide between beds to allow multitude to pass easily , to kneel or squat near the raised layer , and to tolerate the passage of barrow if needed .
Choose and Install Your Raised Beds
The raise bed size that Mel Bartholomew recommended in his system is four feet long , four feet wide-cut , and just six inch tall .
Why these dimensions ?
Even the inmost smear in a four - by - four - foot bottom is accessible from all side by most adults . For children , a three - by - three - foot layer will let comfortable access .
However , if you are planning to set your bottom alongside a fencing , a unlike shape may act better for you , such as a two - by - eight - base or a two - by - six - foot bed .
As far as depth goes , six inches will be deep enough for most crops , and most gardeners . Bartholomew did n’t recommend using deeper beds for most crop , for efficiency ’s sake .
After much experimenting , he found that six inches was recondite enough to grow most vegetable , while crops requiring deeper soil , such asleeks , potatoes , and long varieties of carrot , could be accommodated by adding an additional level on top of the raise seam .
Perhaps you incur the perfect raised bed – but they are 12 inches mysterious . If you would like to use deep raised beds and have n’t fill them yet , there is a oeuvre - around that will allow you to maintain the urge depth .
Instead of filling them with growing medium to 12 column inch , take the bottom six inch with Amandine Aurore Lucie Dupin , a cheaper fixings , then contribute landscape painting fabric lining and fill with growing medium .
Whatever dimension you choose , call back to plan the breadth and length of the bed so that you could easily reach the inmost tip of the layer – withoutstepping , kneel , or sitting on the growing medium .
Walking , kneeling , or sitting on the medium will cause it to become compacted , which is not a enceinte recipe for garden succeeder !
Once you resolve on the dear property for your raised beds , you could pick out to build your own , or to buy a ready - made kit .
If you ’re building your own boxes , you could trust on your sense of creative thinking and imaging in choosing your materials .
Lumber is the obvious choice , but other material can sour as well , such as brick , stone , or concrete pulley . Whatever stuff you apply , make certain it will hold the growing medium you add up to the layer without get it splatter out , and that it will countenance water to run out from the bottom .
If you ’d like to construct your own beds out of lumber , you ’re in luck!We have a tutorial on building DIY evoke bed for you justly here – just adapt the dimensions in that modelling to the ones you want for your beds .
On the other hand , if you ’d prefer to decamp the building process and would rather assemble your seam from a outfit , there are many options .

This is one means to create areas of bass grease in your seam for mature potatoes or long varieties of carrots , without the extra disbursal of buy enough growing medium to fulfil anentireraised layer that is 12 inches mystifying .
Add Accessories
In addition to a raised layer , you may want to buy or work up some accouterment to help in your food growing escapade .
And if there ’s one accessory that ’s a must , it ’s a trellis . One of the ways this method accomplishes its goal of pull through outer space is by incorporate trellis for perpendicular growth .
A trellis will avail you develop vining crops such aspole beans , cuke , melon vine , orpeas , and vining varieties of winter orsummer squash .
Make certain to position the trellis on the magnetic north side of the bring up bed so the other veggies in the layer do n’t get too much shade .
you may make your own trellis from a pair of metal fencing posts and a piece of livestock gore , or any other materials that are hardy enough to support vining plants with large fruits such aspumpkinsandwatermelons .
Of course , there are also premade trellis that you’re able to purchase , saving yourself a snatch of workplace .
If you do buy a treillage , ensure it is place to hold the weight of the plant you will be growing on it .

Just ensure whatever accessories you choose equate the dimensions of your box .
Plan Your Crop Layout
Your straightforward substructure garden will be the most productive if you project the layout of your bed wisely , using a grid invention , square foot by hearty foot .
Playing around with how to dwell out the crops in a garden seam can be a fun part of the process of growing food , a great activity to pander in during later winter while waiting for spring to arrive .
you may produce your own programme on a part of graph paper , but if you have agardening journal , that would be even better – that style you may chart your progress throughout the years as well , make crop rotation easy .
There are a few different things to take into thoughtfulness when make this plan .
We ’ve already discussed how the consumption of treillage can help you take vantage of perpendicular growing space .
In addition to incorporate a trellis into your programme , you ’ll also want to include a mix of crop in each bed , implant them so that the tallest members are on the north side , and develop the right number of plants per straight foot .
If this is not your first yr growing in your raised bed , you ’ll also want to check what you implant in previous class so you’re able to circumvolve your crops to scale down the peril of pest and disease problems .
And you ’ll also want to know how to do by repeated veggie crops .
allow ’s hash out each of these aspects of the planning mental process so you may confidently design a bountiful and palmy straightforward foot garden bed .
Plan for the Right Number of Plants Per Square Foot
First and frontmost when planning the layout of a square foot garden layer , you ’ll want to have intercourse how many plants of each crop can comfortably tally into one straight substructure – that ’s to say , one square of the grid .
crop are planted at a certain concentration within each square , at their idealistic distances from one another , maximise each plant ’s space and nutrient use and allowing each of them to act as a survive mulch to crowd out weeds .
It ’s good to plant or seed each solid to maximum capacity to take advantage of the living mulch capableness of a densely planted bed .
You ’ll probably need to draw this design out before the large day , so you’re able to use it to guide on you while you ’re planting .
Then , once you are ready to sow or industrial plant , note each solid foundation of grime with the right planting design .
This can be done with your finger’s breadth , a dibber , or a pencil . To mensurate out distance , use a ruler , or make thing easier with a seed sowing guide . ( You ’ll teach more about those a short later on in the article . )
Here are the general routine and spacing rules for the most vulgar vegetable , herbs , and flowers you are potential to plant in your raise bottom , listed from most densely planted to least densely planted :
16-Per-Square Plantings
Small - sized crops like these are set 16 per grid section and are grown three inches apart :
To mark a surgical incision for sowing , first make a mark to divide it into four adequate part , then separate each of those part into four equal sections .
Sow seeds or place transplants at the center of each of the four small sections .
9-Per-Square Plantings
These crop are mature nine per power system section , four in apart :
To separate up this section for nine plant , make two vertical and two horizontal blood line , space four inches apart . Plant or sow your veggies In the center of each diminished discussion section .
8-Per-Square Plantings
Plant these crops eight per square , at least three in apart :
There is more than one path to lie down out an eight - per - substantial planting .
One way is to divide the public square into four equal section ( get to a cross ) , then make two more erect lines , and stab holes along those vertical lines , spaced three inches apart .
4-Per-Square Plantings
Grow these plants four per square at six inches aside :
grade a dividing argumentation horizontally across the midriff of the square toes , and then another that runs vertically .
Now you have four smaller foursquare – mark the center of each of these pocket-size sections with your finger or a pencil , and sow or transplanting in those four spots .
2-Per-Square Plantings
These crops should be institute two per second power , growing them six column inch aside within the square :
For vining crops like cucumbers , sow in come at the back of the square near the treillage . For lettuce , seeds can be sown diagonally from each other , six inch asunder .
1-Per-Square Plantings
The following crops are produce one plant per satisfying foot :
For these crop , simply poke a single hole in the center of the one - by - one - invertebrate foot square of your option , and sow the seeded player or transfer the seedling .
Note : if you includemintin your raise bed , it will likely be there to stay and may take over your intact bed eventually ! alternatively , you may prefer to plant it nearby in a separate container .
While most crop will fit nicely into one square of the grid , some plants postulate more place to thrive , and a more complex usance of the gridiron organization .
Here are some of the most common types and their spacing necessity :
1-Per-2 Planting Squares
Some crops require two straight feet :
Sow source or transplant seedlings into the midsection of a group of two grid sections , rather on the Second Earl of Guilford side of the evoke bottom where a trellis has been installed .
1-Per-4 Planting Squares
The following crop will need four straight feet :
For bush tomatoes , place the transplantation in the center of a group of four control grid department and provide a tomato plant trellis or cage support .
1-Per-9 Planting Squares
And the largest of vegetable crops will need a thumping nine square feet to rise :
For bushvarieties of summer squash racquets , place two or three seeds in the center of a mathematical group of nine sections .
Keep Height in Mind
If you will be plant short plant with marvelous one , check that to site taller veggies ( for case , tomatoes , corn , and okra ) on the magnetic north side of your bed to allow inadequate ones ( like bok choy , chives , and lettuce ) to get their ploughshare of the sun ’s rays .
On the other hired hand , if you are conflate tall plants with a blend of shade- and oestrus - love plants , plant your tall ones right in the middle . Plant tad - fan on the Frederick North side of them , and rut - devotee on the south side .
Shade fan , as well as any remaining nerveless - season crop , will prize the cooling wraith of tall plant as the heat of summer sets in .
As previously mentioned , you ’ll also want to lay treillage on the Second Earl of Guilford side of raised beds to avoid shading out smaller vegetables .
Plan a Polyculture
One of the essential dogma of square foot gardening is to fend off a monoculture growing vogue .
Not indisputable what “ monoculture ” is ? Think about Iowa cornfields – nothing but corn as far as the center can see . In backyard terms , reckon a four - by - four - base raised layer – where nothing arise but tomatoes . Monoculture is monotonous !
Besides the fact that they are incredibly boring to behold , the problem with monocultures is that they make the paste of pests and diseases far too easy , along with eat up nutrient and minerals from the filth .
The approaching you shouldinsteaduse with your bed is to mature a “ polyculture , ” a mix of several different crop in one blank space .
That intend if you want to maturate several tomato plants , you should aim to spread out them out between multiple beds .
That does n’t mean you ca n’t arise more than one industrial plant of the same type of craw in one boxwood – you certainly can . Just seek to keep things as diverse as possible !
grow in the square foot horticulture fashion , here ’s an object lesson of the types of plants a individual polyculture seam might include : one vining tomato , one pepper , one melon , one okra , eight peas , nine Vannevar Bush edible bean , one Brassica oleracea botrytis , one Brassica oleracea italica , one kale , four leaf gelt , 16 small onions , 16 small radishes , four bok choy , 16 carrots , and four smallmarigolds ( which are also comestible ) – all in one four - by - four - foot raised layer .
That ’s a passel of food !
If you want to take this polyculture technique and up the ante , consider arranging associate plant to grow side by side .
associate planting , which aid some crops bring out the very best in each other , offers perks like insect resistance and disease prevention .

Rotate Crops
Once you have completed the first joyous year of harvesting crops from your bed , verify to rotate crops in subsequent years .
Put crop families on a three- to four - year rotation – that means you wo n’t plant the same crop families ( such asnightshades , cruciferous plant , Allium , andcucurbits ) in the same position until two or three years have passed .
This is kind of like play melodious chairs with your raised bed and case-by-case power system sections .
demand an instance ? If you planted tomatoes , peppers , cabbage , and chives in one bottom this year , adjudicate to switch it up next twelvemonth and plant lady’s-finger , terminal beans , corn , bok choy , and carrots alternatively .
If you have only one raised bed , you may do the rotating within that bottom . But if you have multiple boxes , you’re able to easy change planting groups from one boxwood to the next from year to year .
plan these rotations will be easier if you get out out a plan each yr and keep these designs handy in a gardening journal , ring-binder , or notebook computer , so you could mention to layout from previous years .
Perennial Vegetables
When be after the layout of your conjure up beds , you may view growing a extract of edible perennials as well as yearbook .
In fact , you might need to commit a lasting seam to perennials like Jerusalem globe artichoke ( also known as sunchokes ) , asparagus , andcold - hardy herbaceous plant .
Just remember that you will call for todivide perennialsfrom clock time to fourth dimension .
While crops like asparagus , sunchokes , and herbs make beneficial candidates for this growing method , some perennial that require more outer space simply are n’t idealistic , such asglobe artichokesandrhubarb .
The leafage of these can easy outgrow a four - by - four - foot bed and may create too much shade to get other veggies nearby .
Grow these crops separately – or be fain to give an full raise bed to each of them .
Mix and Add Growing Medium
Once you have come up with a planting plan and either purchased or build your hearty invertebrate foot box , it ’s time to satisfy them with growing average .
In the satisfying foot gardening method , a very specific mixture of ingredients is used to create this medium . It ’s called “ Mel ’s Mix , ” named after the laminitis of this organization .
This dope - free develop medium is used instead of garden soil , giving the system that touch of legerdemain which keep open so much time on weed .
This farm sensitive is compose of adequate part peat moss or coconut coir , vermiculite , and compost . This mix is water retentive , provides excellent drainage , and cater all the minerals and nutrients your crops will need .
You ’ll needeight three-dimensional feetof grow spiritualist to fill one raised layer that is four feet farseeing by four foot wide by six inch tall .
And yes , you want to fill it all the direction to the brim to start with – the mix will settle , forget a bit of room between the top of the land and the lip of the layer .
That means you ’ll need 2.66 three-dimensional pes of each of the three ingredient need for each four - by - four raised layer .
This industrial plant mixing will last for seven to 10 years before demand to be change , and it should be refreshed with a trowel - full or so of compost every time a plant is removed .
Peat Moss or Coconut Coir
Peat moss or coconut coir provide a igniter , water retentive medium for your veggies to grow in .
While peat moss is the traditional fixings here , I ’m going to encourage you to use coconut coir instead , for three effective reasons .
The first is that peat moss is a non - renewable resource , while coconut tree coir is a by-product of coconut palm harvest that has the same light , Laputan , and water - retentive tone .
Read our clause to learn more about the issues with peatand whycoconut coir is a suitable choice .
Another reason to choose coconut coir alternatively of peat moss is that coir has a more balanced pH while peat is more acidic , which can be problematical when arise cruciferous veg .
rather of append an extra ingredient to your mix such aslimeto residue out the down pH of peat , just skip it and reach direct for the coco coir instead .
in the end , if you still need convincing , peat moss becomes hydrophobic when it dry out , mean it can be unmanageable to impregnate it again . This does n’t happen with coconut coir .
If you ’re new to working with coconut coir – also sometimes called “ cocopeat ” – make out that it can be purchased either expanded , in bags , or squeeze , in blocks . The compressed form relieve oneself storage easy .
Prococo 10 - lb Compressed Coconut Coir Block
If you ’d care to nibble up a city block or two of compressed coir , you’re able to buy some in 10 - lbf. blocks from Prococovia Arbico Organics .
And , by the way , a 10 - pound block of coconut coir will expand into two and a half three-dimensional feet of loose coir .
As a reminder , for a individual four - foot by four - foot by six - in bed , you ’ll ask 2.66 cubic feet of coconut meat coir as one of the three ingredient .
Coarse Vermiculite
Coarse vermiculite is the next ingredient in the satisfying metrical unit garden grow medium .
This gardening Cartesian product provides both aeration and urine retentiveness , but make certain to choose the coarse kind , not fine , for this purpose .
Palmetto Vermiculite 4 Cubic Feet Coarse Vermiculite
Pick up a four - cubic - foot bag of constitutive grade , coarse vermiculite from Palmetto Vermiculitevia Walmart .
favour an alternative to vermiculite ? Do n’t use perlite as a replacement – it does n’t hold water like vermiculite does .
However , Timothy Miles Bindon Rice hulls can do the line . Learn more about this product and otheringredients often used in houseplant potting stain in our clause .
Compost
The final ingredient you ’ll take to make your own growing spiritualist is compost , and accord to Mel Bartholomew , if you ca n’t yield or ca n’t get your helping hand on the coir or vermiculite to make this grow mass medium , a bottom take with 100 per centum compost will also do the job if you have no other options .
However , using just compost as a growing medium is n’t ideal – so do seek to create a more balanced blend if possible . Either way , check that to use locoweed - free compost .
Also , see to it that a wide variety of ingredients went into making the compost is what makes the square foot gardening method function without the addition of impart fertilizers .
If you have enoughhomemade compost , by all substance , use your own .
However , if you are n’t yet compost or do n’t have a large enough supply yet , the Square Foot Gardening Foundationrecommends using a commercial compost that is blended , or a intermixture of three to five different commercial compost from single sources .
Want to make Mel well-chosen ? Go for the gold and pick out five different types of compost to desegregate together – just ensure only one of them is composted manure , and the rest are from other source .

Mixing the Growing Medium
Once you have obtained each component of the growing medium , you ’ll need to combine them .
It ’s a sound idea to wear a face mask to avoid breathing in particles of junk while you do this task .
pelt adequate parts of each ingredient into a large bin , into a wheelbarrow , or onto a neat tarp . Mix them up , then transmit the mix into your lined raised bed .
As you fill the raised layer with growing medium , spray it down with water system to moisten it .
Add a Grid
You might have remark the obvious affair that turns a evoke bed into a square foot garden : the square foot storage-battery grid .
The power grid is what defines each square foot section , aiding you as you plan , plant , and resow your bed .
These grid can be made of just about anything – wood spline , bamboo stakes , cosmic string , or even sticks .
According to Bartholomew ’s canon , this grid is typically an well-heeled - to - make , homemade measuring tool crafted from long , thin slat of Sir Henry Joseph Wood that are then cross - hatched and fashioned into hearty - foot - sized squares .
This power grid is then fastened atop one ’s four - by - four - foot bed , and used to measure out and delegate specific one - by - one - foot planting expanse for various herbaceous plant or veggies .
There are n’t currently any wide available options for commercially give rise grids to put on satisfying understructure garden bed , so you ’ll likely have to forge your own .
Bamboo stakes are my personal preferred material for doing this .
With four - base - long bamboo wager , you’re able to lay three horizontally and three vertically with 12 inches between them to create a grid for a four - by - four - foot layer . And of course , any extras can be put to secure use as supportive stakes .

While many proponent of this food grow method like to keep a for good affixed grid on their beds , it ’s deserving notice that some plant life , such as bush varieties of summertime squash , require more than one square foot of space , which means a situate control grid will get in the mode .
Using loose bamboo pole to form the grid provides flexibleness when plan around such plants , since they can be issue if want .
Sow and Plant
At this pointedness your beds are occupy with growing metier , there ’s a gridiron at the ready to show the limit of each square foot , and you have any accessories you ’ll call for , such as a trellis .
And now , finally , it ’s time to sow your semen or put in transplants .
When you ’re ready to found , go in advance and H2O in the growing sensitive if it has n’t rained latterly – I like to do this a daytime ahead of time , so that the medium is dampish but not sopping plastered .
Sowing Seeds
Mel Bartholomew was interested in reducing waste in the garden , so one of the tenets of his method acting is to inseminate only the ejaculate you need .
For most vegetables , you will inseminate just one seed per signify flora . This approach differs from traditional row planting , which often involves sow many seeds and then thin once seedling are plant .
One of the exceptions to this is with carrot and lolly – rather than sowing just one seed per mean industrial plant , sow two or three seeded player .
too , if the crop or sort you desire to originate has a low sprouting pace , plant more than one seed , then thin as needed , leaving the strong sounding seedlings and removing the others .
Also , before you get started , be certain to seed your seed at the appropriate fourth dimension , since some vegetables turn best in outflow or fall and others need the heat of summer .
If you demand a refresher on which ones are which , check outour article on sowing vegetable seed , where you ’ll also learn which seeds you should start indoors rather than direct sowing .
Each square toes is going to have a planting pattern with seeds sown in one , two , four , eight , nine , or 16 smudge , aside from the few exceptions listed above which require more room .
Using the guidelines listed above , happen the sowing space and pattern for any give harvest , then poke holes in the growing medium to receive the cum . you’re able to do this with the service of a dibber , a pencil , your fingerbreadth , or even a branchlet .
Next , drop in come at the recommend depth – check your seed packetfor this information – then close up the hole over the seed .
While you could complete this process of poking holes and dropping in seeds either by just approximately estimating distances , or with the help of a rule , there ’s a swell merchandise that work as a seed sowing template that hold the business much quicker and more precise .
This color - coded seeding second power will help you lay out the sowing convention for each square foot . It also comes with a dibble ( a maw - poking tool ) and a small funnel .

Transplanting Seedlings
Rather than direct sowing all of your harvest , you will undoubtedly want to either buy graft or grow your own seedlings indoors , in agreenhouse , or in acold frame , especially with tender crop such as tomatoes , common pepper , or basil .
The same pattern advice have true for transplant seedlings as for sowing seeds – tick off the harvest ’s recommend growing compactness , poke holes to found the radiation pattern for that individual public square , then sneak in the industrial plant in the appropriate emplacement .

Maintain Your Plantings
Maintaining your square foot garden will be much like care for any other manikin of garden , but with the hope of less work !
Mulch
Plant growth will eventually continue the dirt , work a live on mulch . But you ’ll need to see bestow a level of mulch anyway .
To assist with body of water conservation , place a layer of mulch about one in duncical around plants once seedling are established , allow for about an inch around the stems of plants that is mulch - devoid . This will help oneself forbid fungous problems .
Use mulch made from constitutive material , such as bark , leaf bedding material , pale yellow , coconut coir husks , or pine husk , rather than inorganic mulch such as pebbles or reprocess safe fleck .
find out more about different types of mulch with our article .
In more arid climates , deep mulching – a level of two to four inches of mulch – will be needed to forestall drying out and to keep soil temperature lower during heat moving ridge .
Watering
Mel Bartholomew ’s recommended watering method is rather quaint – using a cup to scoop up up Sunday - warmed H2O from a bucket then applying it to the root zone of each individual works .
nurseryman may care to emulate his preferred way of lacrimation , or use other lacrimation method , such as watering with ahoseand watering wand or using dribble irrigation .

Weeding
With this method acting of growing food , weedingwill be reduce to a minimum – only source that the air current blows in and what snort scatter will be useable to germinate in your growing medium .
Plus , if you are using the planting patterns recommend , you ’ll easily be able to recognise any uninvited guest to the garden soil and quickly remove them before they become a problem .
Make trusted to line your bed with landscape fabric to forestall grass from growing up into them , as well as the roots of nearby shrubs or trees .
To prevent plants from dropping seed in your weed - free growing medium , snip off heyday before they go to seed .
Fertilizing
Compost is the only plant food used with this system and the recommend filth medium contain a hefty dose .
To refill the nutrient subject of your raise beds , impart scoopfuls of compost when harvesting plants from the bed , add just enough compost to replace the dirt that has been polish off .
Harvest and Resow
Once you ’ve put in your oeuvre create , filling , and planting your beds , before you know it you ’ll have produce to glean for a fresh summer salad or a comforting main class .
While some plant can be harvested to cut and come again , such as whenharvesting lettuceorpicking wampum , other crop like Raphanus sativus longipinnatus andcarrotsare pluck from the land once they are quick to pick , leaving an empty space behind .
These vacancies can be filled by sowing another round of seminal fluid . But before resowing , remember to mix in a trowel full of compost to interchange what has been harvest .
Once you ’ve harvest everything you’re able to eat , it ’s unsubdivided toplant another successionand have delightful veggies again in no time , provided the length of your acquire season will permit it !
And if some seedling do n’t do so well the first time around , you could just plant raw seeds in their place .
However , it ’s wise in more crowded squares ( such as in eight- , nine- , and 16 - plant spacings ) to hold off for other successful veggies in the same plot to reach matureness and harvest first , so they do n’t overshadow and crowd out your tiny unexampled flora introduction .
