Blueberry Disease or Pests
Hi. Hope someone can help. I have 5 blueberry plants Misty, South Moon. All have adequate irrigation and slow release fertilizer. They get about 4 hours of morning sun. Shade afternoon. This is a new problem that appears to be spreading. See images. Early new tip growth dies back-to red then black. Berries dry up and fall off from clusters. Some may be okay later. I've sprayed these, but my timing is late...I think.
