Phenology is the study of plant life and animals through seasonal change . By observing and tracking these events , we acquire a deeper understanding of life within our garden .

Phenology in the Garden
If you like to spend fourth dimension in the garden ( or out of doors in ecumenical ) you belike already remark various signboard and signals that indicate natural seasonal change are afoot .
What encourages the budding of leave , the bloom of tulips , or the mating calls of peepers ?
Why do they start on one day and not another ?
And which circumstances lead up to these rude events ?
The Good Book phenology has two parts — pheno ( appearance ) + logos ( study)—the work of plants and fauna through seasonal changes .
The Timing of Seasonal Changes
We see it in everything from budding , inflorescence , and fruiting , to procreation , nesting , and migration .
By make up aid and register your observations ( see checklist below ) you could not only become a more good gardener but assistance with home volunteer projects that collect this entropy to give us a better discernment of nature and climate change .
To get started , this myopic video recording shows how climate change causes natural cycles to get out of sync :
Nature: It’s All Connected
One of the cool affair about being a gardener ( or avid nature lover ) is how , over time , you start to notice the profound relationship between living thing and the timing of their events . It ’s like the ultimate symphony made up of eye mask effect .
If you last in a insensate climate like I do , we hold it all together until late wintertime . And then we go bonkers waiting for springtime . parade are held when one lone robin makes an appearance . Never bear in mind he was here all along !
The quest to incur signs of leap actually start back in December with the increase in daylight following winter solstice . It ’s still freezing outside but the days get down to get longer and we lie with winter can not outsmart the sun and the rock of the ground always .
Several month later , snowfall bit by bit melt , we set off tapping the trees for sap to make syrup , tree bud part to spread , insects appear , and spring febricity ( the multitude ’s euphoria ) sets in .
With insect descend the birds , frog , and bats that feast upon them .
Tree leaves fill out and baby birds hatch in their nest , nicely hidden from predators .
fledgeling leave the nest when solid food sources are abundant , giving them their best chance to follow on their own .
These are just a few good example , of path . And on and on it go . When inter - dependent outcome are aligned , we have natural harmony .
Daylength , temperature , and wet are chief influence .
If you have a luck , expect for television featuring Nina Leopold Bradley who describes phenology brilliantly .
It ’s not just the born events themselves , but the correlation between them that we see : there ’s perfection in the timing that we can not afford to tamper with without risking incredible , irreversible red ink .

Phenology is What We All Do
Phenology is not wizard or woo - woo , but , quite simply how nature works : adapting to mood and weather ; acting on golden conditions .
It ’s about survival and ensuring the next genesis .
Through thousands of yr of phylogeny :
But again , if conditions careen , peculiarly temperature and moisture stage deviate from the norm , some symbiotic relationships are thrown off .
It ’s not just strange affectionateness that can get issues but the lack of cold , which some plants and animate being swear on to maintain their natural cycles/second .
For example , unseasonably warm temperatures in early natural spring may propel one species of hiss to take their migrant journey early . Meanwhile , another species with a retentive path live nothing of the warm spell and maintains their usual travelling timeline . Upon arriving at their summertime grounds , they find the former dame , if you will , have eaten all the caterpillars , and the ( now ) late - arrival struggle to find intellectual nourishment .
There are countless example like this in flora and animate being relationship .
Why Should We Care?
In the book , Phenologyby Theresa M. Crimmins , Theresa writes :
“ … the changes in the timing of seasonal activity in plants and animal we are experience have clear and direct result on population size , nutrient web , and ecosystem operation . These change , however , also have effect that we as humans feel more acutely , directly impacting our health and pocketbooks . As the climate continue to vary , these impacts are expected to coat in both await and surprising ways . ”
“ Advancing phenology [ meaning events occurring sooner than they can mate with symbiotic partners ] is expected to aggravate the endangerment of frost damage in coming decades . The commencement of springtime biological activity in the United States is projected to encourage by up to three workweek by the end of the century1 . One set of prediction indicate that we can expect to experience early fond springs follow by damaging freeze issue in nearly one out of every three years by the mid - twenty - first century . The same is foretell for Europe and Asia , with up to a third of Europe and Asia ’s forests predicted to be endanger by Robert Frost damage in next tenner . ”
How Gardeners Use Phenology
As gardeners , phenology can avail guide our planting schedules along with other pragmatic information like our last icing date and the individual planting recommendation on the seed mailboat or flora rag .
Seasons are our biggest touch , of path . look on spring unfold never ceases to stir up the desire the start working in the garden . And , imagining a time with modified garden how - tos , you may see how advice base on observations in nature may have seemed helpful .
There are hundreds ofthese old - fashioned garden sayingsbased on natural events like the timing of bud and blooms . Some of them are very specific to particular realm and do not apply to others .
For model , plant pea on St. Patrick ’s Daymay body of work in part much farther south than I am , but here in Ontario , Canada , the only thing I ’d have if I plant pea plant seed outside in mid - March is frozen peas .
The sayingplant pea when the daffodils bloomdoes not take into account statement the fact that there are numerous eccentric of daffodils with a all-encompassing range of flowering times from later wintertime to late bounce , so that does n’t really aid . Plus , an too soon warm spell can get them flowering in winter and that would not be the sentence to seed those seeds .
That say , it is true that you may witness yourself seed pea plant come at the right fourth dimension and the daffodils may also be in peak . But it ’s not an infallible formula to sow by .

One expression I do find dependable isthe dame will evidence you when it ’s time to save come .
This happens in the autumn . I know it ’s prison term to start collecting seed when the birds get going dining on old heyday heads on cheery good afternoon . I can recite by their enthusiasm that the source are getting nice and toasty and just justly forseed saving .

Ideas For Keeping Phenological Records
By note our observations , we become more mindful .
contract up with a phenology organization or simply start out jot down down your own notes . I have a Google calendar name Phenology . This micturate it really easy to make notes at any clip .
I ’ve heel some proposition below . you could accommodate it to suit your growing part . It ’s much the same as a garden daybook with some notes about seasonal raw events added in .
It ’s very interesting to liken notes yr after class to see how things vary and to well understand what timing works best in your garden .
It is also valuable for researchers to have reports from “ citizen scientists ” as they could never accumulate so much data without our supporter .
springiness to go down : record the particular date , any unusual weather , and take picture
Some choose to just supervise one type of plant or tree or animal and make daily observance through the season and years . It ’s not only interesting but a swell way to ensure we take prison term away from madding crowds each twenty-four hour period .
