    I have an arbor of old concord grapes which I have been pruning and watching since 1986 when I moved to this property. Some years they produce a lot of fruit and then other years they are practically barren. I spray some with sevin, captan and bourdeaux, but I never have used any fertelizer. Shoud I? Also are there any sprays which are easier to use and when should I use them?
