I aquired some bulbs last year, and planted them in a pot.
I planted them close together, all in one large pot, as is typically advised. I planted them shallowly to the neck of the bulb (like amaryllis) watered them, and they took off. Unfortunately, they did not flower. They grew well with fine grassy leaves all summer, and I took them indoors in November. They stayed dormant over the winter, but by March, with not encouragement from me, they were showing very ready signs of growth.

I put them outside April 1, and again they took off.
As July approaches howevever, as I realizedthey have still not bloomed, and I begin to fear the great pumpkin has passed me by once again.

Has anyone had better success than I have.

I understand that, if the bulbs are exposed to heat they produce offsetts at the expense of the individual bulb. It is recommended that the pot be shaded, or sunk into cool soil, with the tops in good light. Presumably culture aimed at the developement of the individual mature bulbs aids in flower developement.

Also reccomended is a high phosphate fertilizer in Fall as the bulb goes dormant to promote flower bud developement.
I have not applied this. I grow organically, and I simply did not have any of this kind of fertilizer, but I will see what I can do.

The bulbs I grow got a cool period in fall, a dry period in Winter and another cool period this Spring.

Looking forward to hearing other members success stories!
Best wishes,
