Low - growing plants with magnanimous flowers , the small corms – not reliable bulbs , but similar – have brilliant cold hardiness and the intensely dark flowers often emerge in previous winter before spring officially arrives .
They ’re a democratic choice for seasonal priming covers , in naturalized plantings , and in bed or borders , and they make a handsome container plant life as well .
After flowering betimes in the growing season , the foliation and roots start to die back as they develop to enter their summertime dormant period .
No growth occurs over summer but with the comer of capitulation rains , ancestor resume development as the electric-light bulb come partially out of dormancy .
With the uptake of nutrients and urine , offsets are puppedin cool nightfall temperature and some foliage may appear at this time as well .
The corm stay in a semi - dormant state over winter and ask an prolonged chill time to finally break out of quiescence . After chilling , and once the days start to lengthen in February , flowers take after shortly thereafter .

When and How to Lift
By the fourth dimension all the foliage has die back in late spring to early summer , the corm are inactive and can be safely lifted .
To tell if they ’re dormant , the foliage should be brown , papery , and easy pulled liberal .
Avoid lifting corm before the leafage has buy the farm back – the leaf are involve to collect and process energy through photosynthesis , which is then stored in the corms .
Before they enter dormancy , it ’s a good idea to mark the gist of the clump with a garden tag – this aids with accuracy when digging them up .
habituate a clean trowel or spade to dig around the thump carefully , permit four to six inches of ease out from the root zone to prevent cutting or damaging corms .

After lifting , the corms need to cure before pass away into storage . That ’s next !
How to Store

Lay the bulbs on a piece of cardboard or covert in a single level and place in a warm location out of lineal sunshine with good air circulation .
Allow the bulbs to dry for seven to 10 days , turning them over after three or four days .
After curing , trim away any remain foliage and rootage and brushing off any missed soil .
If want , you may dust the corms with a fungicide – but this is n’t necessary if they ’ve been cured before warehousing .
Place the corms in a paper travelling bag and fold over the top to shut it . meshing bagful work as well .
Place the suitcase in a cool placement with temperatures of 50 to 65 ° fluorine and store for up to five months . In warm temperatures above 70 ° F , damage to the corms can come .
contain the corm after they amount out of storage and before planting . Discard any with planetary house of radioactive decay , mold , or gentle flesh .
Vernalization Needs
For unfolding to occur , corms need a tingle time of 12 to 14 hebdomad at temperatures of 45 ° F or depressed .
Within their hardiness kitchen stove , the required shudder sentence is naturally meet when imbed out of doors .
But for pull bulbs , you ’ll need to cool them in the icebox for 12 to 14 weeks to meet their cold requirement .

When to Plant
After storage , plant outside in beds and containers once the stain temperature have dismiss to 60 ° F or below in the drop – you could find the details in our guide onwhen to plant crocus bulb .

Bright, Early Blooms
Few things brighten a dreary wintertime landscape better than the vivacious , other heyday of crocuses !
