I was out like I am every day yesterday, and during my visit to the four plant blueberry patch, I noticed the Blueray has a few leaves that have turned completely brown, and drooping. Today I've noticed the same issue with some leaves on the other three plants.
Is this just a case of heat stress? It's went from seasonable and wet over most of May to hot, dry and a bit windy the last week or so. I don't think it's fertilizer burn as that was done about a month ago with some Hollytone. Most of that has been diluted down by a bunch of rain since then.
One of the smaller branches has the brown leaves, but also is drooping a bit. Again is all this just heat related? I've watered the bushes yesterday and today. They've been doing great since they got planted the first of May.
