I have a Fukien Tea tree which sits in its own humidity tray at about 60degF and under a daylight fluorescent lamp for about 10 hours each day. After I got it the leaves started to droop and dried up despite daily spraying and some started to drop. I put a polythene bag over it and the leaves perked up and I got some small but new growth including flowers on it, but when I removed the bag for a few days it wilted again and lost leaves. Now I have tried to let it grow without the bag but leaf drop has continued and now I have only a couple of very small but new leaves and one new flower. I have repotted it in case the soil was the culprit but the soil it was in looked okay on reflection. Now it sits there with no foliage but clearly still alive as the wood is still green underneath. What will happen next!??
