Concord Grapes budding but not growing
I have a very old concord grape vine that used to produce mass harvests. My dad planted it. But the last 2 years, it hardly produces anything.
The buds form and everything seems ok. But then only a few of the buds on each bunch starts growing. The others seem to wither and die. I'm going to try and put some pictures here so you can see what I mean. The first one is of a bunch with all the buds still there. The second one is after they start growing--most of the fruits just disappear.
