Hi, new here and was wondering if anyone is familiar with the problem we're experiencing with our young peach tree.
The tree has been in the ground for about 18 months now. We're in Austin Tx where the weather has become very hot and humid this past month. We had a ton of rainfall back in late May through June. The leaves are turning yellow and appear to be burning at the tips - not sure if that's an accurate assessment - pic below shows progression from left to right.
There does not appear to be any reddish tint to indicate a typical nitrogen deficiency and we are seeing some brown spots on the younger green stems. We are also seeing the same issue on a small cherry tree nearby.
We haven't done much in the way of fertilizing, just some basic lawn fertilizer (Milorganite). Not sure if this is a deficiency or bacterial disease, any help/clues would be most appreciated.
