I repotted my 1 year-old china doll plant a couple of months ago because it was losing leaves, and I thought it needed better drainage, so I put rocks in bottom of pot, and have pot sitting on top of more rocks. It dropped almost all its leaves, but has lots of new growth. It's getting bright, filtered light, and I try to keep top moist without letting it sit in water. I mist it almost daily. I also sprayed it several times with insecticidal soap for bugs and think I got them all.

Question: The new leaves are still dropping off very easily. Any suggestions?

Check to see how wet the potting soil is and how long it stays wet. Weirdly enough, putting gravel in the bottom of a pot does not increase drainage, but has the opposite affect. It could be that by trying to improve drainage, you have water logged the soil.

If you feel that the potting soil you are using will not drain fast enough, mix gravel, perlite or something similar into the soil, don't put it under the soil.
