Can you help identify problem with our peach tree?
Our peach tree's leaves are turning yellow with what appears to be burnt tips (pics are attached). We're not seeing any reddish tint to the leaves or stems, which I understand is common with nitrogen deficiency. The tree has been in the ground for about 18 months. We are in Austin, Texas where the weather has been very hot and humid the past month. Back in late May and most of June, we had a ton of rain. We haven't added much in terms of fertilizer, just fertilized the yard around it a couple months ago with some Milorganite. We're just trying to determine if this is a deficiency of some sort, or a fungal or bacterial disease. Any help or clues you can give us would be greatly appreciated.
This could have started out as a water issue. The heavy rains combined with the heat, these can cause fungus issues.
I would spray with Neem Oil, as do so weekly. It works as both an insecticide and fungicide.
Remove any dead material and dispose of.
I don't think is is a deficiency either but follow the fertilizing schedule in the links below.
