This Arkansas Black Apple been in the ground for three years - seemed to be doing really well. Two weeks ago started to brown up. 15 other trees in this orchard look ok. Yes, it has been 105 and no rain for most part for last six weeks. These trees get this much water for thirty minutes every week. Yes, my water bill is a little high.
Is it drought, disease, or what. Is it going to come out next year - or should I pull it out of the ground and start over.
