Greetings and salutations, everyone; yes, once again it is I, Mani the purebred border collie, filling in for the guy I live with, and here today just to talk about crocuses. You may remember me from such posts as “Crocuses And Snowdrops”, among so many, many others.
Here I am in a characteristic pose.
It’s pretty cold, and it’s going to be cold today, too, but tomorrow, not so much. On our morning walk it was seven degrees F (-13.9 C).
The only drawback for me is that I have to wear my boots, and the only drawback for the guy I live with is that the brightness of the sun on the snow hurts his eyes, even with polarized sunglasses.
Anyway, you may recall the guy I live with’s pontificating about crocuses and their corms. In particular, autumn-flowering crocuses.
He said that autumns are now so dry that newly-planted corms often don’t get enough water to form cormlets after the plants flower, which is why he’s growing some in pots upstairs under lights.
You can see that the leaves in the pot third from the left are starting to wither. He thought the leaves would stay green until spring, but apparently not. They do, growing out in the garden.
What really matters is the formation of cormlets.
In the pot closest in the picture, the leaves had all withered, and he thought it might be because of the heavier, silty soil which makes it difficult for water to infiltrate. He was afraid the corm had died.
He told me (I’m not sure I listened much) that a more porous soil makes it easier for water to infiltrate, and that water is more readily available to roots growing in porous soils.
Like this:
This is old soil-less mix taken from the troughs which were given away.
So he removed all the soil in that one pot, and after searching around for a while, this is what he found:
See the new cormlets? The tunic, or outer covering, of the old corm is at the left and middle.
It may take a couple of years for the cormlets to grow large enough to flower, but the process is well on its way now.
And that’s all I have for today. We’re eagerly looking forward to tonight’s -6F (-21 C), warmer weather after that, then colder weather, then warmer weather, and so forth.

Until next time, then.
