Why Your Crocus Won’t Bloom
1. The Soil
When you think about it , crocuses are fairly telling . They muscle through fresh thawed earth , poke leaves and bud into crisp late - wintertime air .
The thing is , the hardy bulbs need on the loose , well - drain soil so as to get through the three- to four - inch level you embed them in last autumn .
It ’s potential that you were so excited to plant the corm that you bury to verify the grime was n’t too heavy and sandy , or too thickheaded and clay - same .
Or perhaps wet , heavy coke – or even something as uncomplicated as your dog ’s favourite route through the lawn – has compacted the ground and your crocus leaves and buds are give birth a hard time poke through .
Here ’s how to help :
In a pail or other mid - sized container , commix a 50/50 blending of surface soil and compost from your composter , if you have one .
Or get this premade worm casting compost in 1 pound , 5 pound , or even 1 cubic infantry bagsfrom Arbico Organics .
Worm Casting Compost
Ideally , if you hump your soil is overweight or compacted , you should knead this intermixture in when you plant the corms .
But if you ’ve long since planted the bulbs and are prove to help them push out of the ground , you ’ll have to get your horticulture gloves on .
Hopefully you remember where you plant the corms . ( To avoid potentially forgetting , make a rough drawing off of your yard and sketch the field you plant with crocuses and other bulb . Your future ego will give thanks you ! )
With a trowel or your fingers , carefully work the first two or three inches of earthly concern above the bulbs . Try not to actually dig up the bulb itself .
Work the topsoil and compost blend into the land . You should end up with a looser territory that suck up and drains water nicely . Give the expanse about 1/4 inch of body of water .
The spiky leaves should now be able to drive through the earth and turn into vibrant blossom .
2. Bad Bulbs
Sometimes , a dud bulb is the cause for your crocus troubles .
Before planting , watch your bulb for sign of rot by squeeze them between your pollex and index . They should feel firm , not soft and squishy or dry and flaky .
Bulbs that are bad from the present moment you open your newly purchased bag need to go directly back to whoever deal them to you .
Purple and White Mix Crocus Corms
Find some reputable one instead – like thesefrom Eden Brothers .
You should always imbed your medulla as soon as you’re able to after you grease one’s palms them , which is why reputable gardening stores only trade natural spring - bloom bulbs in the fall , and fall - blossom bulbs in the spring and summer .
If you wait too long to engraft them after buying , the bulbs can rot . They ’re felicitous inside their earthy homes .
3. Fusarium Rot
Say you had a beautiful crop of crocuses last year , but now you notice stunted yellowish leaves farm out of the priming coat and no flower in visual modality .
moil up a corm or two and check for fusarium bunk , the most probable culprit , according toJanis Ruksans , writer of “ Crocuses : A Complete Guide to the Genus . ”
Crocuses : A Complete Guide to the Genus , useable on Amazon
This disease is n’t likely to impress vernal crocus once they ’ve been planted , so long as you live inUSDA Hardiness Zones3 - 8 .
If you live in Zone 9 , you may still plant crocuses but you demand to chill the bulbs in the refrigerator for 12 - 15 weeks during the winter .
Otherwise , fusarium waste in the main affect warm atmospheric condition loving saffron crocus .
You ’ll have to toss out infect medulla oblongata and go soft on the fertiliser ( or use none at all ) , as too much nitrogen can contribute to fusarium putrefaction .
4. Gray Mold
If your area is having a very rainy class , check for gray cast .
This have black or brownish spots on the corms and often rots the flower buds before they can emerge . The leaves will sometimes still break through the earth without the bud , only to buckle under to the mould within a few days .
Or , flowers may blossom only to become covered with a cottony gray-haired film .
To prevent the mold from spread and killing more of your bloom , cut away all affected parts of the industrial plant and spray what ’s pull up stakes with fungicide .
You ’ll then take to dig up the corms to ascertain them for those blackish dark-brown spot ; if they ’re infect , make them out . Spray all the rest of your corms with fungicide to prevent further damage .
5. Critters
Maybe you keep trying to plant corm only to ascertain mouse and squirrels drudge them up the next Clarence Day .
If this is you , I know your painfulness . I had a huge , gorgeous pecan treein my backyard when I lived in Oklahoma .
I never got to eat one single Carya illinoensis from that tree . Our backyard host a colony of witty squirrel who ’d sit on my outer kitchen windowsill so I could watch them eat my precious pecans while I moisten the dish aerial .
The tree was so tall , it was hard to keep the critters out . They ’d leap from smaller trees into the large one and rust the nuts before they could return .
gratefully for you , crocus corm are easy to protect .
Here ’s a utilitarian method acting for you to essay :
Use Chicken Wire
All you have to do is purchase a duration of wimp conducting wire and some metallic element stake . The same solar day you plant your bulbs , cut a department of the fencing with wire cutters . Make it about three feet wider in circumference than the area where you planted the crocuses .
Lay it down flat over the planting country . Using a hammer and the stakes , affix the net to the terra firma .
This will keep the squirrels from accessing the earth around your precious bulbs .
If you notice that the bud that came up so attractively last year are follow up this class , too , but are then disappearing before they can bloom , you might have a larger wrongdoer on your hand .
Like cervid , if you populate in the Lower 48 . Or , if you ’re like me and live in Alaska , Alces alces .
I had a athirst young garden - undoer that ate all my cabbage one class , plus all the leaves off my orchard apple tree , plum , andwillow trees .
I approximate I had n’t learned much from my squirrel fiasco in Oklahoma .
The very same night the Alces alces aggress myprecious yield trees , I run to the gardening store and buy supplies tobuild a moose - proof fencearound each one .
They ’ve been good ever since , as you may see in the photo of one of the Malus pumila tree ’ first salad days post moose - pocalypse .
Exhausted at the idea of build up a fencing around the intact area you planted with crocus ? Fear not !
There ’s a better path .
( Two , actually . )
Plantskydd Repellent Available from Amazon
Yuckily enough , Plantskydd is made with dry blood of the porcine and bovine sort . The feel alerts deer and other herbivores to the bearing of likely predators , so they stay away .
Plantskydd worked well on my herbs and carrot garden , which I harvested and enjoyed before found that fated cabbage .
It also work on my trees – until I draw a blank to re - apply it to the new growing , as the bottle apprize you to do .
Now I spray the surface area where I have plant my bulbs and my non - fenced tree with Plantskydd when I think back , which is n’t often enough , because moose came along recently and chomped my little birch Sir Herbert Beerbohm Tree in half .
Those rascals .
If you have trouble remembering things like I do , try the second method acting : plantingdeer - resistant bulbsalongside your crocus corms .
Daffodils , snowdrop , andhyacinthsare all toxic to deer and moose .
The bulbs , folio , and flush are all immense no - nos for these garden - muncher ( and also squirrels ! ) , so you’re able to reap the benefits of their protection from the day you tuck them in alongside your crocus corms .
Grape hyacinthsand snowdrops are perfect for planting in the same trench as crocus corms , as all three have bulbs that need to be bury 3 - 4 inches deep .
Grape Hyacinth and Daffodils
you could plant Narcissus pseudonarcissus bulbs three inches below your crocus corms , where they wo n’t render quick tribute ( since they ’re not side by side ) , but will help repel creatures once they all bloom in early spring .
6. Inadequate Planting Depth
When you initially plant the bulbs , verify to constitute them three inch down , four max if you live in USDA Hardiness Zones 3 or 4 . snaffle a rule and assess the astuteness of the hole or trench to be completely trusted .
Here ’s why you have to be careful : a crocus bulb , or any bulb for that matter , might fail to produce buds if it ’s implant too deep .
This can cause bulbs to rot or to produce foliation but no flush , as they have been meddling putting energy into corm development . Or they may just be lease longer to emerge and you might need to be patient .
You ’ll also want to avoid planting bulbs too shallow .
If you do n’t plant your corms deep enough , they might be expose to too much temperature fluctuation during wintertime , as they are not insulated by the soil . It also leaves them vulnerable to pests , as mentioned above .
7. Not Enough Sun
If the efflorescence you planted last fall are n’t blooming , check to make indisputable they ’re getting enough fair weather .
crocus like full fair weather or part shade , so keep an optic on how much igniter they ’re getting throughout the solar day .
For crocuses that blossom delicately last year but are n’t blooming this twelvemonth , sun is n’t likely to be the problem – unless you plantednew shade treesright over your crocuses .
( Do n’t do that ! )
8. Over-Fertilization
Did you fertilize your corms when you planted them , only to find that they ’re not blossom in the outflow ?
Some generator will distinguish you to fertilize the grunge around the corm itself . Others say to wait to inseminate untilafterthe bloom efflorescence .
Still others urge avoiding fertilizer completely because too much of it can burn or damage corms .
Here ’s what you take to keep in mind when you ’re think about fertilizer :
If the soil you ’re planting in is already well - draining , dark , and crumbly – signifying that it ’s rich in organic thing – you really do n’t ask to fertilize the crocus .
The roots will pull all the nutrient require from the healthy soil .
An excess of nitrogen in the fertilizer can impart to fusarium rot and may also cause foliage to appear without bloom .
For weighty or arenaceous grime , you still do n’t need fertilizer – just compost and surface soil .
If you do want to supercharge your flower with fertilizer , it ’s likely safest for your corm if you implant them as common , light tamp down down the globe above them , and scatter a cup of granular constitutive fertilizer , such asthis one available from Home Depotover each straight foundation of planted filth .
This should prevent the fertilizer from damaging the corms while allowing it to smarten up up your foliage and bloom .
9. The Wrong Temperature
One last culprit ? The weather .
Here in Alaska , we often experience wildly vary winter temperatures .
One winter can be mild , only dipping below zero for one or two days of the entire season , with spring make it much earlier than common – in March or April as opposed to May , while , we relish weeks of below - zero temperature throughout other wintertime , pushing the spring melt to belated May or even June .
The reason your crocus are n’t flower yet could be as unsubdivided as a variety in the atmospheric condition from last twelvemonth to this year .
So , since they cansurvive in the cold and coke , have a little longanimity and keep look out for those vibrant flowers to pop through the earth !
Crocus Culprits Begone
Now that you know the nine top culprits that can prevent your crocuses from blooming , it ’s time to go set things straight in your lawn and gardens so you could enjoy those vivacious flower .
