The Q&A Archives: Grapevines

Question: We have lived in our current house for 3 years, and inherited a well established grape vine. It has yet to produce any fruit at all. We let it go without pruning the first year, 2nd year we pruned it way back, and it looked like

Answer: Grapevines usually begin producing when they are 3-4 years old and they are self fruitful so you won't need another grape variety in order to have fruit. If the plant is blooming then you should have fruit, weather permitting. Sometimes weather conditions interfere with the flowers opening fully or interfere with the pollen moving through the flowers completely. A cool spell or a rainy spell during this critical time period can severely limit the crop. (Optimal temperatures would be 65 plus degrees.) Unfortunately there really isn't too much we can do to influence the weather. Some varieties of grapes are not suitable for your area because they do not have enough summer heat to mature. So fruit can set and grow into hard green clusters but never have enough heat to fully mature. I don't know what variety you are growing or whether it is suitable for your area. Let's hope it's the right variety and all you will need to do be a little more patient until it matures a little more.
