I have a Japanese red emperor I bought and planted this year. the problem I'm having is all of the leaves have brown holes throughout them as well as some wilting. I have mulch around the base and water it daily. I have looked the tree over for signs of insects that might be eating them but so far I haven't found any. I live in Tn and it's been in the mid to high 90's consistantly this summer. I have not fertilized with anything to date.
