Spring arrived with lots of rain then the bushes flowered. And man did they flower. I looked on and said to myself that there is going to be one hell of a crop. Then the berries started and most stopped growing. I was a able to pick a few quarts but they were not well formed. Now 90% of all the bushes have died and new shoots are not plentiful. I know about thinning the crop out and cutting back the old stocks, but something seems wrong. Could it be because of the very wet spring?
