Comments On - Mystery of the Unripe Grapes

I am having the same problem with my grape vine. I dont know what kind of grapes they are I have resulted in picking the ripe grapes one by one.

I am unsure what triggers the grapes to turn. I noticed the clusters on the far west side of the vine had more ripe grapes. The vine is thiner there so idk if it is the sun that is causing it or cooler tempratures at night but the clusters in the thick of the vine are all green.

I did cut them back last winter, and I havent seen any pest like i have in the years past which is strange normally the vine is flooded with bee's.

I am open to any suggestions or insight to this grape situation.

Some years even the vines don't want to put in the work that we think they should.

Hi David,
Yeah, it's weird. Some others around here are having this same problem, but not everybody. Too bad, I just got a grape crusher today, it would have been nice to make grape juice, but I've got too much other stuff to do. I'm going to rebuild the whole grape trellis this winter and cut the vine back about fifty percent. I'm fairly confident that this lousy year won't repeat often.

I have never grown grapes so I don't have any advice but it sure is a mystery especially when others around you are not having the same problem. Growing plants certainly is a challange and nature seems to always have a mystery up her sleeve doesn't she?

Have a great garden day.
