How often are you watering the plant?

That happened to mine this year too when I missed a couple of days of water during hot spells. They still look terrible but mine are still alive because the tips are putting out new green growth

Mine are also dying. Turning yellow brown, curling and NO fruit. Some of the stems have just turned brown/dead. First berries were wonderful, sweet. But only got a few (5-6).it has been raining here in E TN nearly every day, so they don't need water. Any suggestions?

Mine doing same, hot weather and not enough water I think is the culprit because I only see it after things heat up.

By the way, my virus software just popped up saying there was a threat from this site but luckily it caught it!
