Habineria: Where are we going wrong?

[David1985]

Hi all,

My mother is growing an Habaneria medusae from its bulb (a much larger bulb than she started with!) and everything was going well. She got two leaves, and all was well, but about a month ago one leaf got brown spots on it, went limp, then fell off. Now the other leaf is doing the same.

She was not spraying it before the first leaf fell off, then started spraying once it did. Now the other one is doing the same. The bulb is firm and moist; no roots to speak of (assuming it's supposed to have them) and it's in the original growing medium. It's in a east-northeast facing window and it's been a hot and humid summer. Direct sun is gone by 11 am; it was originally in the sun, but was moved behind another one in case it was getting too much.

Any pointers?
