Sun scorch destroying blueberry patch?
After 100 plus degree temps for 17 straight days Im losing blueberry bushes hand over fist. These are two year old bushes most were healthy lush green and 2 to 3 ft tall prior to these temps. I have leaf scorch surrounding the leaves and on some, and just ends up burning the whole leaf. I also have observed browning of stems and eventually just killing the whole stem. It starts out as a maroon stem going along the length of the stem, then it ends up brown and killing the stem. Has anyone else experienced this issue. I still have a portion of the bushes that are healthy and only have minor dieback problems. IM guessing the smaller the bushes the more prone to extreme heat is the problem. These bushes have been adequatly watered and the ph lowered to appropriate leavels as well. IM very discouraged and have already placed a fall replacement order for some new ones. thanks
