It needs to live outdoors, in South Florida. They want full sun, a soil that drains well, and fertilizer (once established). I don't know what you mean by "lining." Can you show a photo or describe what you are seeing? Overwatering, and the shock of being moved can cause Citrus to shed leaves. Where did you buy it? Will they help you? Is it small enough to take back so they can evaluate it? The loss of a few leaves is not serious, but when it sheds lots of them, that means something is wrong. Lisa

That is strange my fig trees are still producing leaves. I am not expert but from my reading the leaves are very important for the health of the fruit. They produce sugar and carb and send it to the roots and in turn the roots feeds the fruit. In your case could be lack of nutrition and the trees are not able to handle the load of fruits and leaves. This just a guess or could be lack of water or too much water. My brother in law lives in Orlando and he mentioned to me it have not stopped raining for three months.

Maybe replace that Halogen with a CFL. THey can be put within an inch of the plant as they give off almost no heat unlike a Halogen. Removing the heat mat is a good idea as habjolokia said. Also, I dont know what kind of fertilizer you are referring to but if it is liquid, and you are dumping a straight 1/4 shot glass with watering, you may be way over fertilizing. The liquid I use is a 9-3-6 and it is supposed to be cut at the rate of 1 tsp per gallon of water. If yours is a similar ratio, you are probably way overdoing it. Just read the directions and follow them. You may also want to consider a fert with a bit different ratio. Yours is pretty low on the Nitrogen side and high on the Potassium side. That would be a fertilizer maybe better suited to a mature plant that is ready to or already putting out blooms and fruit. But my first guess is that the lighting is your major problem. Bruce

I'm in Laguna beach California never very cold here Today is 63 I asked at our local nursery and he said the same thing need to water I just fertilized yesterday also It's never had this much fruit which is nice, but there's no new growth anywhere on the tree.Its been in this pot 4-5 years Probably needs to come out and have roots trimmed if I want to leave it in the barrel.
