My Concord Seedless (which has seeds for me) is in its first year of wild production. I have clusters everywhere, even after the bird tax.
But the grapes in a cluster don’t seem to ripen all at once. I’ll have half purple and half green on a cluster, and I’m not sure when to pick them.
Am I doing something wrong? More sunlight? They are not in an ideal planting position, growing up my back porch.
