Q.Grapevines Not Producing Grapes

Zone Vermont (1700 feet) | JoeJS added on August 28, 2012 | Answered

My grapevines are not producing any fruit at all. They are at least 4 years old. What’s the problem and how can I correct it?

Thanks,  Joe

Have you pruned any? Grapes form on new wood. This article should help: https://www.gardeningknowhow.com/edible/fruits/grapes/prune-grape-vine.htm

Your soil could also be lacking phosphorus, which is responsible for flowering/fruiting in plants. A soil test will allow you to know for certain; however, it will not hurt to add some bone meal to the soil around your grapevines to add more phosphorus.
