Right here’s what we’ll cowl:
What Are Offsets?
Crops have a number of methods of reproducing themselves. Seeds are one apparent methodology and these are the results of sexual replica, the seed comes from a pollinated ovule.
However many vegetation even have asexual replica strategies, just like the manufacturing of offsets.
The phrase “offset” is a broad time period for part of the plant that may be propagated. This is likely to be a tiny clone, a chunk of stem, or part of the roots.
Crocuses develop from underground constructions referred to as corms. These are massive, swollen stems that may retailer water and vitamins. They’re typically confused with true roots, however botanically they’re truly stems.
The corm is roofed in a protecting sheath known as a tunic. The aboveground stem and finally a blossom or two emerge from the highest of the corm, and roots emerge from the bottom.
Some species have what are referred to as contractile roots. These are specialised roots that steadily pull the corm deeper and deeper into the soil. That’s why you’ll typically discover corms as a lot as eight inches deep.
All species develop fibrous roots, which anchor the plant into the soil and take up water and vitamins.
Younger, growing corms are referred to as cormlets or cormels. Each these and mature corms may be faraway from the mum or dad plant and propagated individually.
When to Propagate
When to divide the corms will depend on when the plant flowers.
Spring-blooming crocuses embrace the long-flowered (C. longiflorus), early (C. tommasinianus), snow (C. chrysanthus), Dutch (C. vernus), and fabric of silver (C. versicolor).
The species that bloom within the fall embrace Kotschy’s (C. kotschyanus) and saffron (C. sativus) crocus. Don’t confuse these with autumn crocuses, which aren’t within the Crocus genus in any respect. These belong to the Colchicum genus regardless of the frequent title.
Hybrids would possibly bloom in spring or fall, so determine when your particular kind blooms earlier than propagating.
Spring-flowering sorts ought to be propagated and planted within the fall. Fall-flowering sorts ought to be propagated within the spring.
The exception is saffron, which blooms only a month or two after planting, so you’ll be able to put these within the floor in late summer season for fall flowers.
You don’t need to be too precise concerning the timing. As long as the soil may be labored and the climate isn’t freezing, it’s a fantastic time.

I choose to plant instantly after dividing the offsets, however that’s simply me, I don’t like storing corms and bulbs if I don’t need to.
Dig Up and Divide Corms
The method begins by digging up the prevailing plant. That is the trickiest a part of the method since you don’t wish to harm the corm when you’re attempting to take away it from the bottom.
I wish to err on the facet of warning and dig a bigger perimeter than I count on to wish.
The corms themselves aren’t normally very massive, relying on the species, however they won’t be rising instantly under the aboveground stem, which implies if you happen to dig proper down, you would possibly by accident hit the corm.
To keep away from this, I both mark the world the place the stem was rising or take a look at the place the stem is at the moment rising, and I dig a foot diameter across the middle of the stem.
Which means you’ll dig six inches in every route from the stem.
Dig not less than a foot deep, however ideally just a few inches extra.
Gently carry the part of soil out and brush away the filth till you discover the corms. It’s also possible to wash away the soil if you happen to’re apprehensive about nicking the tunic.
Keep in mind, the corms are coated in a dry, brown, protecting sheath known as a tunic. Don’t take away or harm this if you happen to can keep away from it.
You won’t have the ability to keep away from damaging it or it would come off when you’re cleansing the corms, so don’t fear if it isn’t intact.
Gently separate the offsets. You may plant immediately or retailer them in a dry location with a temperature of about 40°F for eight weeks.
An unheated storage or shed works, simply set them in a cardboard field and check out them commonly, discarding any that turn out to be mushy and mushy or odor funky.

Planting
Once you’re able to plant, dig a gap about six inches deep or thrice as deep as the peak of the bulb. Most ought to be planted about three inches aside, at the least.
Set them within the gap and canopy with soil earlier than watering in nicely.
After that, let Mom Nature deal with the watering except you will have an especially dry fall or spring.
