When I published this postabout fertilizing peony , I already recognize I was going to publish about some of the ground why some peonies do n’t bloom . But my determination was before long validated after I shared the tie to my post on social media .
Not one , not two , but three of my Facebook champion complained about having ( or having had ) peonies that did n’t bloom . Or if the plant did set bud , the peony buds did n’t overt .
And what is more interesting ( at least for me , as a flora author ) is that every case wait a small bit dissimilar – someone has just imbed the peonies , while someone else suspected the bush had been in the new - to - them garden for at least a decade . One of my admirer is obsessed with reading all the horticulture advice they can obtain , while another has more of alaissez - faireapproach to their backyard efflorescence .
So I decided to prod deeper and explicate the main reasons why your peonies do n’t blossom , and what you may do to lick the trouble :
1. Your peonies aren’t supposed to bloom at this time.
Do you get laid for sure what kind of peonies you have ? I do n’t mean to sound condescending , so I apologize if my interrogative come across as such . But with hundreds of peony cultivars usable on the market , you have to verify you know what sort you have before worrying about their lack of bloom .
Some peonies bloom in belated spring , while others may flower in June 21 . Depending on the climate you garden in , that can sometimes translate to a two - month departure in flower time .
So before you reach out for that bottle of plant food , make certain you ’ve got the timing mightily .
you may extend the blooming seasons of your peony patch by interlard cultivar with different flush times . Always see the agriculturist ’s recording label for this information before you purchase a new flora .
Here are a few suggestions to get you started :
Peonies that bloom in mid - spring :
‘ Chocolate Soldier ’
‘ Athena ’
‘ Early Scout ’
peony that bloom in previous spring :
‘ Claire de Lune ’
‘ lawcourt Jester ’
‘ Rimpo ’
‘ Coral Sunset ’
paeony that flush in early summer
‘ Shawnee honcho ’
‘ Felix Supreme ’
‘ Duchess of Kent ’
‘ Mother ’s Choice ’
‘ Cora Louise ’
Peonies that bloom in mid - summertime
‘ Sarah Bernhardt ’
‘ Mr. G.F. Hemerik ’
‘ Bowl of Beauty ’
‘ High Noon ’
2. Your peonies are too young to bloom.
verbalise of constitute fresh peony , keep in mind that it read about three year for a small plant to get establish enough to put out a rich display of blooms .
If you ’ve just planted your peony , you should allow it some time to get acclimatize to its unexampled location . The first order of clientele for the flora is to redirect most of its energy into root formation , with very little Department of Energy leave behind for blooms .
Also , attempt to resist the temptation to harvest blooms for peak displays during the plant ’s first few years of emergence .
And if you have successfully grown your peony from seed , first of all , hats off to you ! Secondly , you should know that it takes much longer ( about four to five eld ) for plants grown from come to progress to maturity and flower .
3. You’ve just divided and transplanted your peonies.
To debar letdown , treat your newly transplanted peonies as if they were untried plants because in essence , they are . Even if you have divided and removed them from an sr. , more established crotch hair , you should n’t expect the new graft to perform as well as the one-time increase . At least , not in the beginning .
This is particularly truthful for peonies that have been carve up in late summertime – they will not bloom well the next spring , since you ’ve interrupted their fall bud setting . alas , that ’s the best metre for divide peonies but be prepare for slower growth for at least one time of year .
4. Your peonies are planted too deep.
Whether you ’re planting a unexampled peony that you ’ve just buy or a root division that you take yourself , ensure not to implant it too deeply . The “ eyes ” ( the tiny shoot ) of the peony tubers should only be about one or two inch below the surface of the soil .
If you plant your peony too deep , you may get some gorgeous foliage , but very little rosiness . If this happens , just count it as a lesson learned and have patience until the next time of year . The industrial plant will work itself into a dear position before the arrival of the next growing season and you ’ll get beautiful blooms .
While we ’re talking about plant deepness , make certain you take into consideration the layer of mulch that you ’ll be adding on top ( to keep the moisture in , the weeds down and the soil temperature even , of course ) . Plant or transplanting with that add summit in judgement .
5. Your peonies need more sun.
One of the most common misconception in horticulture ( and one that I often charm myself believing , even though I should have it away good ) is that “ tolerant = thriving . ”
Let me explain . In the lawsuit of peony , the fact that they can tolerate shade does n’t mean that they will flourish in the shade .
Your peonies will thrive in full sun and postulate about six hours of unmediated sun for store enough energy for beautiful blooms . Yes , they will tolerate idle shade , and they may even set buds , but the flush will be sporadic .
This is an of import factor that sometimes changes without us even notice . For good example , when you first planted your garden a few year ago , you made sure to plant your peony in full sunlight . But in the meantime , the shade map of your backyard may have exchange . perhaps you put up some social system ( such as a gazebo or a pergola ) or maybe some of the trees and shrubs in your yard ( or the neighbor ’ ) are casting more shade than when you first decided on a place for your peonies .
What you could do in this case is to hollow out the paeony in the fall and transpose them to a raw area that gets enough sun .
6. You’ve used too much fertilizer on your peonies.
In my opinion , over - fertilization is a case of good intentions coupled with poor execution . Although sometimes it ’s also a case of following the instructions on the bottle of fertilizer ( which often overvalue how much plant food you need ) .
First of all , keep in mind the key to fertilizing any flora that blooms : low nitrogen . Nitrogen , one of the main components in fertiliser , promotes foliar development . But the more energy the industrial plant put into lush leaf , the less energy it has to devote to flowers . ( Yes , even if you ’ve been feeding it . ) So you may have a green robust Vannevar Bush with only a couplet of flowers in blossom .
The root , especially if you ’re prone to over - fertilizing , is to lend organic compost to the land around the peony plants and turn the compost into the ground ( gently , do n’t disturb the root structure ) .
you may also add a balanced fertilizer ( 10 - 10 - 10 ) or a plant food low in nitrogen ( 5 - 10 - 10 ) in former saltation , before the Modern growth appear .

7. You pruned your peonies too aggressively or too early.
Peonies use their foliation to feed the roots below through photosynthesis . So even when the peak are gone , the plant is still working hard for next year ’s blooms that are beginning to form under the open of the soil . If you disrupt this cycle by pruning the foliage too ahead of time , before it ’s had clock time to feed the new maturation , you may cease up paying for your restlessness the trace mature season .
So do n’t remove the foliage prematurely . You should only cut it back to the earth after the first frost , when the leave have browned .
And if you ’re growing tree paeony , never prune them down . Unlike their herbaceous cousins , tree peonies are bush and they will not grow back if you hack them down to the ground .
8. Your peonies suffered from late-freeze damage.
This is often the casing when the buds do come along , but they never afford up into full blooms ( a phenomenon also call ‘ bud blast ’ ) . In my belief , it ’s even more irritating than having no bud at all , because it does produce a sense of expectancy that fails to happen .
alas , this happens more and more often because of unusually strong early leaping spells . industrial plant are play a joke on into believing it ’s time to bloom , then a operose freeze in late April or May get and zaps your paeony ’s blush .
You could attempt to isolate the flora with a frost cloth or improvize a mini - burrow . But if the temperature dismiss importantly below freeze out for more than a day , there ’s not much you could do about it .
9. Fungal diseases are attacking your peonies.
Again , this is another scenario in which your paeony does get bud , but never blooms .
One of the most common fungi to attack flower bud , especially in wet and coolheaded conditions , is the Botrytis blight , also sleep with as gray mold . You ’ll see dark splotches on the fore and on the leafage ; often , the paeony will look wilted and the bud will just turn brown and shrivel .
countenance ’s just say Botrytis blight is not a pretty sight . you’re able to attempt to fight it by using a fungicidal spray specially design for Botrytis . Unfortunately , the blight spread very tight which makes it hard to catch in the early phase .
The best solution is to clean the site for the following yr . move out and destroy any pathologic foliage or buds as soon as you discover them . ameliorate air circulation and attempt to keep the leaf teetotal when you water the peony bush . quash using spraying hoses or soak the plant in weewee .
10. Your peonies can’t complete with surrounding plants.
paeony are not needfully territorial plants , and they do n’t circulate aggressively . But they still need to have their own space , especially if they ’re under threat of being encroached upon by shrub or trees .
Peony roots , no matter how racy , can not contend with the solution system of a Sir Herbert Beerbohm Tree , which can create dry condition and very compacted dirt . This can often result in inadequate blooming or no flush at all .
I trust this account of why your peonies are n’t blooming has been helpful . I know it may look overwhelming , especially for new gardener , but if you work to eliminate the causes methodically and with a lot of forbearance , you will be rewarded with a undulation of blossom next growing season .
