I haven't put on any fertilizer on it. As far as watering, I think I've been under-watering it. because I used a drip soaker hose and those thing don't put out much water. That's why I'm removing it and just use my water hose. One thing I notice is since I transplanted it, I've been losing all the old leaves. Now on the tree, there are only 4 or 5 leaves remained from before the transplant. The rest are new leaves.
