I'm on my 2nd lemon tree. I live in Melbourne, Australia and lemon trees are the norm around here. I suspect my first one died as it outgrew its pot, which was half the size of this one. I'm currently renting, so need to keep it in a pot until I buy then I'll plant it in the ground.
Bearing in mind it is Winter here, I spotted that the leaves are beginning to wilt and also have spots of white which then end up being holes. They look a little like burn marks, but I have not been watering in the sun nor has it been too sunny recently.
Any ideas on how to save this tree before its too late?
