How to Have Grape Vines Produce Grapes

Question

I have 3 year old Concord grape vines with a pH of 6. 0-6. 5. We live in northern Virginia. I have NEVER had even one grape. What could be the problem.

Answer 1

Grapevines need a few years before they start producing at all, and 6-7 years before they start producing to full capacity. I would give them another year or so for fruiting.

As a precaution, you can give the vines some bone meal. Plants need phosphorous to fruit and bone meal is a good source of this.
