blueberry bushes suddenly look dead

Asked August 20, 2020, 3:11 PM EDT

I have blueberry bushes...quite a few. 2 of them suddenly look like they are dying. leaves appear to be drying up around the outside, with a red/brown outline around the dried up part on the inside. we have checked the waster system, and they seem to be getting water. other trees and vines in the area are fine. We have checked PH - which was around 6. we started to leave coffee grounds around them about 2 months ago. Haven't checked the PH since. This happened in what seemed like "overnight." I am out there almost every day. One day it was fine, and the next the leaves on 1/2 the bush were bad, and now the entire bush(s) appear to be dead. Same thing happening to a blueberry that is in a different part of the yard, and away from this bush.. It's leaves started to look the same this morning. yesterday it was fine. Also where the first two bushes are - there are evergreen blueberry bushes. 1 bush looks fine, the berries are growing. The other one, closest to the two that are bad, it's berries aren't growing well, and look dried up. The leaves on the evergreen seem to be ok, though they are turning a little red and lighter green, the other evergreen blueberry isn't. Thanks so much for your help!

Thank you for your question. It is difficult to diagnose plant problems without photos, so the best I can do is to refer you to an Extension publication on growing them: Your soil pH is still too high. It needs to be between 4.5 to 5.5. Perhaps a professional soil test would help. ( Coloration on leaves indicates a pH and/or nutrient deficiency. You don't mention watering, mulch or fertilization. I hope this helps narrow down potential issues. Good luck!
