cutting back grape vines
I cut my grape vines back and I think I might have cut them too far back. I left the major vines but cut all the little vines off because I had powdery mold last summer. Will they grow back?

Grapes are vigorous plants. The recommendation usually, is to remove 90% of last year's growth each year to maintain vigor. Your grape plant is probably just fine. Grape fruit clusters are produced on current year growth from buds on one-year old canes (last year's growth). You can train grape vines to a wire support, as is usually done with wine grapes. You can also train the grape up an arbor or as a fountain-like head. . The main goal of pruning is to develop a well-established root system to suppport the plant's growth. We tend to get distracted by the above-ground growth.
