Red globe grapes

Question

My red globe grape is fruiting for the first time after I planted 3 years ago. The fruits are small, the size of a small marble and the taste is sour. Please advise me on how I could have bigger and sweeter grapes.

Answer 1

A 3 year old grape vine is still a baby, so it may well be that all it needs is time. Also, make sure you're leaving the fruit on the vine long enough. And most important, make sure your vine has optimum care. This article should help you get started. https://www.gardeningknowhow.com/edible/fruits/grapes/growing-grapevines.htm
