atemoya tree trouble
I'm new to this site. I just bought an Atemoya tree about a week and a half or so ago. I've noticed that some of the leaves are starting to turn brownish at the tips and the backs of them are turning into a black like color. When I first put the tree in I deep watered and have been continuing to water every 3 days. I posted some pictures. Can someone help? Is this normal?
thanks in advance!
