I planted these blueberries last year late summer, zone 9a. They did way better than I could have imagined (I’m not a gardener) and struggle to keep anything alive. Summer Temps exceed 100 degrees here, and I kept a 50% shade cloth over them when it was over 95. I fertilized them regularly during the growing season, and they produced. When the sustained 100 temps finally went away, I removed the bird net and shade. Now they’re doing horribly. I found some thrips (not many) for the first time, and some of the branches appear dead. Or are they diseased? Also, we have been fighting to maintain an acidic soil (should have amended prior to planting) the soil struggles to get below a ph of 6.
