I have a 9-year-old Concord grape vine that is not producing fruit–can you help?
The Gardener’s Answer
Hello, Poncho: Grapes, like any other plant, will produce well if they are given ideal conditions in which to grow. Selecting a good cultivar is essential and Concord is considered a very hardy grape for Kentucky gardeners. Maintaining good fertility and annual pruning are just as important. How long has it been since your vine produced fruit? If this is the first year you are not seeing any fruit, it is still too early in the season for fruit set. They should just be flowering at this point. How long has it been since your vine was pruned? Every year the vine is not pruned it will become unproductive. As for the triple 19 you are using, I am assuming this is a well-balanced fertilizer; it is recommended that grapes older than 4 years should receive 2 pounds of 10-10-10 per vine. These vines should be fed during the late winter/early spring. Too much nitrogen later in the season promotes vegetative growth that can be damaged by the cold temperatures. You can always have your soil tested through the County Extension Service so you know exactly what you need to adjust if anything. You can also take a sample of the foliage if it does not look healthy to your Extension Service. The stream on your property should not be an issue.
