Common Materials to Build Raised Garden Beds
Balancing Longevity, Cost and Safety
In improver to the list above , you could create a arouse garden bed out of just about anything open of holding soil and plants ! A kiddie pool , used tires , rubbish wood found on the side of the road … the optionsseemendless . However , there are a number of component to regard when determine the best materials to go with . Not all are create adequate .
Longevity
Select strong , durable materials to make raised garden beds if you want them to last . After all , garden bed are capable tonear - invariant moisture , outdoor constituent , and potentially insects or pesterer such as termites .
Plus , soil is heavy – especially once it ’s wet ! The more soil mass present ( such as in a tumid or marvelous resurrect garden bed ) the more air pressure will be exude on the seam paries . In that instance , thin wood boards will pronto bow or rot equate to thick lineament boards . Even using the best lumber , concrete or some metal bed will outlive wood raised bed , peculiarly in wet clime .
Cost
Most often ( but not always ! ) , cost is straight linked to durability . High - quality materials that cost more have the potential to last 10 or foresighted . If you opt to save money upfront and pick out more affordable materials , you might be sacrificing the lifespan of your raised bed .
For example , a planter loge constructed of reclaimed pallets or lenient pine Sir Henry Wood likely wo n’t hold up even half as long as one made with premium lumber . likewise , quality metallic element raise bedsshould last far longer than cheaper knock - offs . Likewise , prominent Isidor Feinstein Stone or concrete block will be more than straw bales , but last a actual lifetime in compare !
Now , thatdoesn’t signify you have to pass a fortuneto make raised garden beds . count on your situation , you may be more than willing to give up a small life to keep upfront costs down – especially if you ’re renting your current home , or only setting up a temporary garden space . There are also plenty of style to be resourceful and find a big plenty . Hit up your local Craigslist , Facebook market , junk yards , and more to scrounge for materials .
lastly , be trusted toshop around and compare prices . For example , we are able to observe large deals ( and a larger variety of materials ) for stones , blocks , gravel , bulk soil and mulch at our locally - owned landscape supply fellowship . However , lumber from the local shop has proven to be monetary value - prohibitory , and is far more affordable at the big box computer hardware depot .
Safety
There are heaps of creative and budget - well-disposed raise garden bed “ taxi ” out there – but I exhort you to use some mutual sense ! For example , I would guess twice before using paint or treated salvaged Grant Wood to make a garden bed for edible crops . Especially if the years and source is obscure ! The wood may becontaminatedwith toxic chemical like lead , arsenic , or other heavy metal that can transmigrate ( leach ) into your soil and intellectual nourishment . Even though modern pressure - treated wood is less toxic than clobber they used to make , I still notify against using it .
I ’ve see people expend all kinds of up - cycled materials to make garden bed : likestyrofoam coolers(made ofpolystyrene , a distrust carcinogen ) orold car ties(containbenzene , polycyclic aromatic hydrocarbons , heavy metallic element , and a legion of other substances that are toxic to human health ) . While I applaud the effort to reprocess items in the name of sustainability , I personally do n’t think it ’s worth the risk . See the section below for a arrant list of materials to stave off .
Types of Wood to Make Raised Garden Beds
Cedar or Redwood
Cedar and sequoia are the twobest choicesof wood to make raise garden beds with . They ’re both verydurable , beautiful , and course resistant to moisture , waste , and even termites . The cost of each can change importantly count on where you go . We ’ve witness that sequoia is more affordable on the west coast , while cedar tree is more readily usable and thus less expensive in the easterly US .
Raised garden bed made from redwood or cedar tree should lasta decade ( or two ) – or even longer ! Water storage tanks used to be constructed of redwood , after all ! Cedar and redwood are both technically “ deal ” lumber , yet the mellow levels of naturaltannins(what repels rot and termite ) found in both lay down them significantly more perdurable than other deal . With a higher tannin subject matter , redwood is bruit to last a few years longer than cedar – particularly if you apply heart redwood .
As you ’re browsing the lumber section , you should see options for “ common ground level ” redwood orheart redwood – sometimes referred to as building substance , ‘ con heart ’ , or heart - B redwood . Webuild raised bedsfrom affectionateness redwood , which is more dense and therefore more long - lasting than common grad or sapwood .
As much as possible , choose lumber with an FSC certification . The Forest Stewardship Councilcertifies lumber that comes from “ responsibly managed forests that allow environmental , societal and economical benefits ” .
Other wood options for raised beds
In general , hardwood lumberis more dense so it tender a higher-ranking level of durability and strength over softwood lumber . Examples of long - last hardwood lumber include teakwood , maple , beech , hemlock , walnut , blackened locust tree , and oak . Wine barrels are made of oak tree , both to enhance the flavor of wine-coloured but also to allow incredible moisture - electrical resistance and length of service . See tips about usingwine barrels as raised garden bedshere . While secure , hardwood trees develop more slowly and are therefore far less mutual in twist than deal .
Popularsoftwood lumberincludes Douglas fir , pine , spruce , and juniper . These options are typically more affordable than redwood or cedar , though not quite as durable . Raised garden bed made from these softwood are make love to last about4 to 7 yearson average ( compare to 10 to 20 years for true cedar or sequoia ) , look on your climate .
Another thing to take is timber sizing . Thethicknessof your wood plug-in at once impacts your garden bottom ’s life-time too . A raised garden seam constructed of 2 ” thick plank will outlive a seam made of 1 ” control board or ½ ” thick fencing boards – by far ! We use heart redwood 2×6 ” board to construct our raised beds .
Should I seal my wood garden bed?
In the past , we never sealed our raise beds since we live in a fairly ironic mood . We love the manner that redwoodnaturally eld , untouched . It initiate off a beautiful pink color , turns to a slightly amber tone within a yr , and then fades to a beautiful beachy - barnwood grey . Cedar also graciously ages with time , changing from reddish tan to silver Zane Grey ( unless a sealant is routinely applied ) .
Since moving to our new homestead and build our forever - garden , we did opt to seal our new sequoia upraise bed with several coats ofGarden Sealto extend their life . memorise morehere .
Metal Raised Garden Beds
Metal raised garden bed are the new “ it ” thing ! They ’re modern , silky , and unbelievably durable . Metal raised bed are also normally more affordable and easier to assemble than Sir Henry Joseph Wood bed . Unlike Grant Wood , metal seam will not rot over sentence , swell and contract with moisture , or require much maintenance . That said , galvanize steel raise garden beds are agreat choice for fuddled climates , or someone will fewer puppet or DIY skills !
There are a number of metal garden seam options . You could make your own with sheets of corrugate metal as side within a wood figure . Or , turn a prefabricated alloy container into a raise garden bottom – such as adding drainage hole to the bottom of a galvanized steel animal feed orwater public treasury .
The easy option is to use a alloy raised garden bottom outfit . My friend Kevin at Epic Gardening sells the best ones on the market!Birdiesraised bed are implausibly eminent - caliber , durable , and lightweight but uncompromising . They amount in a wide variety of shapes , size , and colors to fit every garden distance . Use code ‘ deannacat3 ’ to economise 5 % off Birdies bed here !
No matter which focal point you take , be indisputable to usegalvanizedand / or pulverisation - cake alloy so the beds wo n’t corrode !
Do metal raised beds get hot?
Some folks interest that metal garden bed will make their dirt red-hot , but it’snothing to be refer about . Even if the metallic element feels quick to the tactile sensation , damp grunge does a nifty task of buffering temperature swings , especially paired with good irrigation drill andmulch .
The stain in metal bed may get a couple degrees warm around the edges , but not in a room that negatively impacts plant emergence . I ’ve read comparisons that showed the interior ( center ) soil temperature was standardized in wood , cinder block or metal raised bed – though all three are a few degrees warmer than develop mightily in the ground . A large metal bed will continue even cooler than smaller variant , as they have more side surface area vs interior volume .
I be intimate many live - climate gardeners who use metallic element call forth garden beds with no job . Birdies beds start in Australia , and their US supplier ( Epic Gardening ) is down in inland San Diego – both quite hot !
Are galvanized steel garden beds food safe?
Yes , well - madegalvanized blade garden beds are all safe to acquire nutrient in ! ( Note the emphasis on well - made , so prefer reputable and well - rated products ! ) Steel is an admixture of iron and carbon . Through the galvanisation process , blade is coat with a bed ofzincthat efficaciously seals it and prevent corroding and rust . It is very improbable for notable amount of zinc to leach from the finishing into your soil . It takes very acidic condition and many , many years for a galvanized zinc coating to break in down .
Even then , zinc is n’t a bad bozo ! Rather , zinc is a mineral naturally happen in soil – and anessential micronutrientfor plant growth ! industrial plant trust onzincfor healthy origin maturation , for added resilience to moth-eaten temperature , and to sustain other phytochemical processes such as the formation of chlorophyll . However , if your galvanized steel beds start to visibly corrode on the interior , it is best to play it secure and replace them .
Making Raised Garden Beds from Concrete, Brick or Cinder Blocks
Like those made from metal , raised garden beds make from concrete pavers , cinderblocks , or brick have the potential to besupremely durable and sturdy . However , this family comes with a few caveat to conceive ! The facility of concrete block garden beds require a decent level of commitment , specially if you secure them in station with mortar or adhesive . They ’re punishing , create amore permanentdesign than other options , and thus limit your flexibility for modification .
It ’s potential to make garden bed from pavers or closure without adhesive ( e.g. only by stacking stop ) if you keep them fairly shallow . Yet you ’ll require tosecure them in placeif you ’re make a bed two feet or taller , in an area prostrate to expectant rains or implosion therapy , on a side , or to otherwise create a more sturdy installation . It ’s also possible to find interlocking block made for mortarless wall system of rules .
We have made a number of kick upstairs garden area with concrete block and assure them withconstruction concrete adhesive(the same path we made ourconcrete block greenhouse introduction ) . The adhesive material is probably not entirely non - toxic , but we only used a small beading of glue deep between each closure . Also , those beds chiefly domiciliate cosmetic flora over edibles . Be indisputable to let your adhesive fully dry and cure before adding dirt !
Are concrete blocks or cinder blocks safe for gardening?
Fly ashis a mutual concern when using pavers , brick , or clinker cylinder block materials to create raise garden layer . wing ash is a Freemasonry linear that contains heavy metallic element such as radium and arsenic , and is often used in concrete products for added durability . However , there is very niggling scientific grounds available that order whether or not those heavy metals pronto leach into the surrounding soil . If you ’re interested about this endangerment , buy your material from a reputable source where you’re able to demand questions and check specifications to see if fly ash tree is present or not .
Natural Stone Raised Beds
go beyond concrete cylinder block , you could make long - go raised planting orbit using lifelike stone too – such ascobblestones , flagstone , small Boulder , or other foraged stone material . Unlike concrete , there is no concern about chemical substance additives here . Natural stones and rock can be freely stacked , or mortared / glued in space . Because the chassis and size of rude rocks are n’t as cookie - carver as concrete blocks , the construction will require more imagination and finagling to puzzle - piece them together . Yet the finished result will be even more hick , artistic , and beautiful – and fuse in attractively in a natural garden setting !
Avoid using these materials for raised garden beds:
