Blooms Won't Open
I've had some minis going for about 3 years now. Much neglected. Recently, I repotted them and pruned them back. Well ... they really took off and are looking quit nice. But ...
One of them threw a bud. It sat, sat and never opened. Finally, it fell off. Never opened.
One of my other one's has thrown two buds. I wonder what's wrong, and if it will happen again.
They are inside and in a northeast window. Thanks in advance for any help.
