Nomocharis problems

[Catwheazle]

Hello,
I got onions beginning of the year (in early February) Nomocharis. Unfortunately, this drive is not enough. Two have roots get .... nothing else.
Se are in pots in different soil, lime-clay or silicate and more sandy. Both substrates with little or almost no humus. Some are planted in the field, others in the pot in the (warmer) winter garden.
Does anyone have an idea what went wrong?
I suspect that will no longer drive out, or never, even if the bulbs are still ok :-(
Next year I will again try Nomocharis (perhaps seed).
I ll try: 6-8 weeks warm, then cold for 6-8 weeks and then normal out into open land
Should I vielleich the ones in the pot are now set for 6-8 weeks in the refrigerator?
Request for "tuition" :-)

Depending how they had been kept- February may have been a bit late for planting.  They may be okay next year.   They'll do well enough in the garden,  with extra humus added if your soil is lacking that.

Nomocharis will prefer a neutral to acid, humus-rich soil in a cool spot with plenty of water in summer. In my experience they need good drainage in winter so will not like clay. I agree with Maggi that Feb may be a bit late to plant - you are probably best leaving them where they are as they do not like disturbance.

They also do very well in large pots but you need to watch out for vine weevil which love to eat the bulbs - I lost a beuatiful N. pardanthina that way. In the ground they tend to be safer.

OK thank you! Yes, I'll do it.
