Hello. I have a chinese elm and grow it on my balcony/terrace, but for some time the leaves have started to fall. It takes a lot of light, but i don't know if it wants more water or not. It also doesn't seem to be dying becuse new shoots are appearing but i dont know if its normal to fall 7-9 leaves, every 2-3 days? i WOULD be very grateful if you could tell me if its normal or not and what to do!!
