Your friend is right in that they do need a vernalization (cold) period. As to what you should do with them now I'm not sure what to tell you. I would suggest going to the NALS (North American Lily Society) website. If I remember right there's an ask Lilium section. Perhaps someone there can help you.

I got my bonsai tree about a month ago, June 29th, and I put it in my windowsill (north facing). It was doing great, I had been rotating it every day so both sides would get sun and a break from sun, but some of the leaves, on the side that touched the window a bit, were getting sunburned. Out of concern, I moved it from the windowsill to a bookshelf next to, not infront of, the window. I've watered everyday (which I'm guessing is overwatering for this spot) and the leaves have been turning yellowish brown and falling off with touch. I have since removed all the leaves so the tree wouldn't be giving nutrition to dead leaves. Should I move my tree back to it place on the windowsill? Any advice? Please help!

I live in Florida and mine grow outside in full sun. I fertilize 2x a year. Early spring and mid summer. That's it. They grow bone dry in Florida sand. I do not water them. However they are in the ground. Gardenias need lots of light. If you can't provide the light you will not be successful. Try putting it in your brightest window. Only water when almost dry. Stop fertilizing. In Spring you could repot the plant, but try to turn it around with light and warmth now. Jane

My ficus elastica veriegata has been home for two weeks and has not been transitioning well. I water it once a week and it sits in indirect light. Any ideas on how to stop this? The water quality has been checked. It does not seem to be over watered either. Thank You and please help!
