Watering and feeding
Grape vines need to be watered frequently in the first year, at least one deep watering a week -- more often if hot weather causes the leaves to wilt. Do not, however, mulch grape vines: Their roots run deep (ultimately as much as 50 feet!), and once established they actually prefer soil on the dry side. Keep weeds in check by using a hoe to cultivate around the vines. Grape vines don't require fertilizer. A couple of shovelfuls of compost each year in spring should provide enough nutrition. Their roots will generally find whatever else the plants need.
