On vine stalks 2-3' tall, stems have produced several dozen 1/2-inch-long "bunches" of grape-dots the size of a pencil point mark. How do I encourage growth of them into full fruit (last year they disappeared at that size, no fruition). These vines give me huge green growth which I trim all summer, but will do whatever is needed now to reduce foliage and bring out these grapes. Thanks!
It sounds as though your plants aren't getting pollinated. So you see any bee or other activity around? If not contact us and we can suggest other plants to help attract bees and other natural pollinators.
