That ’s because all bulbs , and similar secret structure such as genus Tuber or rhizomes , farm plant that can be classified as either sturdy or sore .
And an easy manner to determine their hardiness or tenderness is by considering their flowering time .
Hardy ones – such ashyacinths , tulips , andsnowdrops – bloom in spring and typically benefit from overwinter in the cold soil .
bid varieties – such ascannas , Dahlia pinnata , elephant pinna , andgladiolus – are summer - flowering , and for the most part , wo n’t survive freeze temperatures or hard freeze when leave in the ground .
These ship’s boat type postulate to be snarf for storage in a rime - free area when plant in gardens that experience extreme cold in the winter .
Liliesare a summer - flowering exception , with many type that are hardy down to USDA Zones 3 and 4 .

Here ’s what ’s ahead :
What You’ll Learn
What Are Bulbs?
A bulb is an clandestine storage organ that persist dormant through the winter , holding the develop foliation and buds that will bloom in the next growing time of year – and these are really remarkable .
These self - sufficient , tidy mail boat comprise everything demand for succeeding growth and reproduction , include the growth of source , stems , flowers , and semen !
Most plant that produce them are perennial by definition , with a period of growth , inflorescence , and seed - context observe by a dormant period . They survive sleeping by storing water and nutrients in these change and dilate fleshy underground sections of their stem or root , which have a rounded or stretch configuration .
And because they contain a great deal of H2O , tender varieties immobilise cursorily when allow in the reason , result in rot and a quick demise .
To protect your rootstock from nippy or freezing temperatures , these tender salmagundi need to be raise and store in a frost - loose area for wintertime ’s duration .
In-Ground Overwintering
Hardy varieties of blossom bulbs , those that can outlive inhuman wintertime soil and chilly temperatures , require little wintertime upkeep and can be leave in the soil during the cold months .
After leafage wilts , garnish aside and clean any detritus from the soil open .
If the region where you are garden is subject to regular freeze - thaw cycles , adding a thick , six - inchlayer of bark mulch , folio stamp , pine boughs , sawdust , orstrawis recommended for protection .
Those grown in containers are more susceptible to freeze - thaw cycle and benefit from a protected internet site and a six - inch bed of mulch through the coldest part of the year as well .
Remove the mulch as soon as shoot let out the soil in former natural spring .
Many gardenersdolift hardy varieties in fall if plant have become overcrowded and need rejuvenation – and if they do n’t have sentence to replant immediately . Lift and store dauntless types as you would tenderise ones , then divide and replant in spring .
Lift, Clean, and Dry
Dig up tender varieties after the foliage has wilted and died back , but before the first frost .
Dahlias are an exclusion . These semi - tippy flora can rest in the solid ground untilafterthe first frost , to produce the biggest and healthiest tuber .
snip any remaining foliage and stem to four to six inches in length .
Fully sneak in a garden fork or spade all around the roots , spaced four to six in out from the stem , then mildly pry up the root nut .
With your finger’s breadth or a soft - briery brush , loosen , shake , or sweep away any clumps of soil clinging to the roots .
dispatch any damaged , soft , or mushy parts and toss them . If needed , use a neat , sharp knife to release damaged sarcoid parts .
It ’s tempting , but do n’t wash your rootstock – adding excess moisture before storage can lead to problems like rot .
And it ’s best not to get out aside or separate large glob at this sentence either – unless you ’re replant straightaway . Cuts should be hardened before storage to protect against bacterial and fungal infections .
Allow the roots to airwave dry for one to two weeks by spread them out on cardboard or newspaper in a single layer . Most will dry within a week , but irises can take up to two weeks , and glad and callas may take up to three weeks .
For drying , choose a warm , dry emplacement out of direct sun with good atmosphere circulation .
After one hebdomad , test for sobriety by trimming a stem by one inch . If the cut terminal is still moist or green , give the bulb another calendar week of drying .
When thoroughly dry , brush off any remaining malicious gossip before pack for storage .

To that end , all rootstock postulate to be store in a breathable medium to allow atmosphere circulation – avoid credit card bin unless they ’re punch or slot .
rather , use ventilated cardboard boxes , mesh bags , paper bags , wicker or seagrass hoop , or wooden bin – really , anything that permits free air apparent movement is fine .
Be sure to label what you ’ve packed away , so you ’ll know which is which if you ’ve lifted various species or cultivars for the winter .
To each container , add a slight layer of an airy stuff such as shredded newspaper , peat moss , perlite , vermiculite , or sawdust .
tot up rootstock in a single layer so they ’re not affecting . Cover with your chosen packing material medium to a depth of about two to three inches .
For imbricate bulbs ( those without a papery tunica ) , scarce patter the packing culture medium with a few drops of water – practice your fingertips to flick on just enough to add a hint of moisture but not enough to make the medium moist . This helps to prevent the physical body from dry out out .
bestow another bed of bulbs and packing medium if hope , depending on the property of your container .
Do n’t add a palpebra to your container , which can immobilise moisture and get mould or rot .
Move jam-packed container into their winter home .

But a few , liketuberoses and Peruvian daffodils , prefer temperatures in the low 60s for storage .
A basement , cellar , W.C. , garage , or shed will typically make near locating , provided they ’re not seal tight and air can distribute freely .
If you ’re stack away dauntless , spring - flowering variety , you may need to make room in the icebox to ensure they receive at least eight weeks of cold vernalization in social club to bloom , depending on the eccentric .
