When magnolias are not in flower , the big leathery leaves provide interest , especially those with multicolored leaf .
The configuration is charming , whether you blame a petite saucer with its umbrella - like summit , or a rare columnlike type .
But let ’s not mince words , it ’s the bloom wereallylove . Even when they only come along for a week or two , their efflorescence season cut short by a tardy halt , we produce these trees for their blossoms .
We link to vendors to help oneself you find relevant products . If you buy from one of our tie , we may garner a commission .
So if a magnolia fails to bloom , it ’s pretty devastating .
Sometimes , it ’s just bad fortune , but other clock time the cause is preventable .
Inour guide to growing magnolia , we discuss how to work these trees in the landscape painting .
This guide is all about the reasons why a magnolia tree may not blossom , what you may do about it , if anything , and how to prevent it in the time to come .
Here are the seven usual causal agent we ’ll talk about :
Why Magnolia Trees Fail to Bloom
1 . eld
2 . insensate Weather
3 . Drought
4 . Fertilizer Problems
5 . Pruning at the untimely Time
6 . tenseness
7 . Too Much Shade
Most magnolia flower in former springiness , but others , like lily ( M. lilliflora),M.xloebnerihybrids , and principal ( M. stellata ) magnolias will bloom a 2d or even third clip in the spring or summertime . This round is ordinarily smaller than the first one , with fewer flower .
If a reblooming type does n’t produce a second moneyed one year , do n’t worry . It ’s a mansion that the tree may have been stressed for some rationality , such as an unusually hot or ironical spring . If the next year is better , the Sir Herbert Beerbohm Tree should rebloom as usual .
Trees that fail to bloom at all are a dissimilar matter .
The first coarse cause we ’ll talk about is reasonably straightforward and the therapeutic is patience :
efflorescence are the plant ’s method acting of reproduction , and as with humans , the plant is n’t quick to reproduce until it hit maturity .
The long time that the plant reaches maturity will depend only on the particular species , intercrossed , or cultivar you are growing .
Some , like saucer magnolias ( M.xsoulangeana ) , start young . It ’s not unusual to see them bloom when they ’re just three years former .
A southern magnolia ( M. grandiflora ) , on the other hand , require a ten or longer to get started .
Here are a few common species and the rough geezerhood that you’re able to expect them to bloom . Remember that this can deviate a slight depend on the specific cultivar .
Generally , the larger the tree , the longer it takes to become set up enough to bloom .
If you have a young tree and it has never bloomed before , it ’s likely your specimen is n’t fledged enough to flower yet – so there ’s nothing to care about .
Add another few age if themagnolia was embark on from semen .
hoar is the saddest and also the most common cause of a failure to flower .
My least pet thing about magnolias is how brief their blush period is – sometimes , it ’s just a week of flush in bound . That means 51 weeks of waiting for the freehanded show .
Then , Old Man Winter decides he is n’t done with us , and he spoil a scarey hoar our way . Magnolia flowers are sensitive to frost .
While the buds can ordinarily survive 32 ° fluorine and low , if the temperatures drop below that when the flowers are starting to open , they ’re toast . Some years , I notice that those pucker deeply into the tree or close to a building survive , but the legal age turn into a chocolate-brown , schmalzy mess .
There is n’t anything you could do unless your Sir Herbert Beerbohm Tree is small enough that you could cast aside some frost textile over it to supply some auspices .
Frost is n’t only a concern when the flowers have open . Some species , such as banana ( M. figo ) , are sensitive to frost , and cold-blooded temperatures when the bud are forming can pour down them , and others will even halt flowering the yr following a stale winter .
Drought , and peculiarly dry conditions toward the close of the growing season in the fall , will strip the tree of the vigour it take to produce flowers .
The blossoms are the tree ’s way of reproducing , so when conditions are optimal , they ’ll use their energy to produce flowers .
But in times of strain , the tree may involve to put all its Department of Energy into survival instead of producing blooms .
Adequate body of water , peculiarly in the fall , is life-sustaining . count on the species , the flat coat should be evenly moist at all times .
If nature is n’t providing enough water , get in there and irrigate your tree diagram to keep the soil moist .
Too much nitrogen from overfertilizing is a trouble for many reasons . For one , it ’s causing serious problems in our body of water systems .
secondly , it causes the accumulation of nitrate in the vegetative tissue paper . But in relation to your magnolia , it results in overweening leaf growing at the expense of flowering .
You should always examine your soil in the spring , or in the fall after most of your plants die back for the twelvemonth .
Gardeners often waste so much fertiliser feed when the ground is already full of the nutrients we are add up .
test the soilis voguish and affordable . you could bribe a outfit on Amazon for as much as a fast food dinner .
I employ MySoil Soil Test Kit and am highly happy with the details and the results . you could purchase your own kitvia Amazon .
MySoil Soil Test Kit
you’re able to also send in a sample to your local lengthiness office for testing and by doing this , you ’re supporting local agriculturalist as you’re able to choose to share the results of your soil trial for universal cognition . That ’s the route I normally go .
Once you have the issue of the test , amend your soil consequently . You might find that you only call for to add daystar and not N or potassium . Or maybe you wo n’t need to add any nutrients at all .
Magnolias start developing their efflorescence buds well in advance of their factual bloom time , usually in the early fall . So if you clip the Sir Herbert Beerbohm Tree in the fall , you end up cutting out the developing bud .
This is the gentle number to prevent , simply do your pruning in the spring or summertime , after flowering . as luck would have it , most specie do n’t involve much pruning to preserve a dainty Supreme Headquarters Allied Powers Europe .
In ecumenical , I advise not to prune magnolia at all unless absolutely necessary .
These are n’t trees that bounce back readily from a pruning , and I ’ve known more than one that never recuperate .
Leave them alone unless pruning is require to absent morbid , discredited , or change shape branches .
If the Sir Herbert Beerbohm Tree go through stress during the previous turn time of year , it might not have the energy to produce blossom the next year . Those blossoms are an vigour - intensive patronage .
Prolonged flooding , pestilence infestation , or disease , peculiarly in the fall when the buds are develop , can result in few or no flowers .
To forefend this , do your best to support your tree diagram with appropriate tutelage , and watch nearly for pests and disease so you’re able to do by them before they stress the tree .

Some species are happy in partial shade , while many need full sun to boom and flush .
M. grandiflora , M. laeviflora , andM. stellatacan all farm in part shade . There are also many cultivars that are bred to plow some specter . But broadly speaking , these trees do best in full Dominicus .
This can be tricky because most species put up some wraith when they ’re vernal , but they need full sun as they mature .
That shit sense when you fancy their raw environs . Young plants start in the understory of the forest and then originate larger than everything around them , taking up all the Dominicus .
So if we plant magnolias in some shade because they ’re glad there when immature , but they mature , the trees are then denied the sun they require .
When a magnolia is in too much shade , it wo n’t bloom .
On a cloudless day , observe your tree and determine how much direct sunshine it pick up . If it is n’t receiving at least eight hours , a want of sun could be causing the deficiency of flush .
you could either found a newfangled tree in a better localization , move your specimen , or prune nearby plants that are block sunlight .
Don’t Miss Out on the Performance
I have literally sat and watch my magnolia trees and the weather prognosis with bated breath to see if the two will agree up .
Will I see blossoms this year ? Will Old Man Winter bankrupt the show ? It ’s trying ! As much as I enjoy my trees during the summer and pin , it ’s that spring presentation that induce them so special .
