We just had our landscaping done, around the end of June. Our landscaper planted a beautiful japanese maple next to our garage, our house faces south. I'm not sure how old it is but it is about 3 1/2-4 ft. in height and the spread is about 5-6 ft. around. The tree probably gets most its sun during the middle of the day. We live an hour south of Salt Lake City and have had several days in the upper 90's and low 100's. The past few weeks we have noticed that the leaves are turning green, not brown, and have thinned somewhat in the 7-8 weeks that it has been planted. Is it OK? How much water should it be getting right now? Is it just going through transplant shock? The local nursery told me to put in fertilizer plugs. As you can see I am a novice at this. HELP! Please.
