I have a Brewster Lychee tree, I bought it several months ago, I became worried about the leaves in the store. The clerk said they are not allowed to fertilize them and that it probably just needed a bit of food. I brought it home and fed it, I put it in a larger pot. I have seen new growth several times, it doesn't look like its dying. I do think it looks stressed, its like droopy and scrunched together. Now I only knew about lychee trees because one of my landlords had one and guess who got all the extra fruit? ME!! I loved those things! And I crave them! Thing is I really don't remember what the tree looked like. So I wouldn't really know if its supposed to look like mine or not. To me I would describe this tree as a self conscious tree!
