OK, here's what I do with mine, and I've had them and they've bloomed for years. I leave them outside and water them until the first frost, which is mild, doesn't affect the bulbs, just the leaves. Then I let them dry out outside in the cool/cold nights and well above freezing days. When all the leaves are yellow (never cut green leaves! the
plant is still using them!) I cut them and put the pots, without changing soil, in my closet, which is the only unheated storage space I have. They want to be cool (40 degrees F which I can't do, but the point is cold and above freezing). They go completely dry. Around Feb. I repot them if they need it - I give them fresh soil every 2-3 years and keep them in a pot at least 3x the diameter of the bulb. When the first one shows new growth, usually around the end of March, I drag them all out, put them in a partially sunny location and start watering them. They bloom. I am in awe. Life is good. When the
flowers die I cut off the
flower stalk. Leaves have started by then. As soon as outside is frost free (25-30 May here in Rhinebeck, NY), they go out under the catalpa
tree. There they get some full sun in the morning, dappled sun for a few hours around noon, and full shade but lots of light in the pm. This works for mine. The only real problem I've ever had was the summer I fed them with a relatively high nitrogen fertilizer. The bulbs split and didn't get large enough to
flower again for several years, although by then I had 4
plants instead of the one I started out with. Sounds interesting, but I wouldn't recomend it. You can cross polinate them and get
seed very easily, but it takes 4 or so years from
seed to
flower.
growing anything from
seed is an act of trust, faith, and patience. Good luck. MEP
