We are having a problem with our Concord grapes only growing to approx. 3/8 inch before ripening. We have seen other Concord grapes that are much larger than ours. Our Vines are two years old and are loaded, but the grapes are small. Any ideas?
"Loaded" may be the issue. A two year old vine in a commercial environment would be stripped of all fruit in order to allow it to concentrate on growing it's root system. Even the third year vines often have fruit removed because the root system is not yet sufficient to feed a full load of berries. Mature vines are still monitored and pruned. I wouldn't suggest keeping more than 5 or 6 bunches on these vines, and it's not too late to thin them even now. Ralph
Thanks Ralph, That is good info to know, I will thin out my grapes in hopes of better things to come. Rick
