Grapes grow best in rich gravelly-loam soil. They should be supported on a 2-strand wire fence or on a trellis, and, in very cold regions, pruned to a low-headed double trunk, so that the tough woody part stays close to the ground and the more flexible canes can be bent down to be covered with mulch in winter. Although our Planting Guide gives some basic information on planting and caring for grapevines, a good book on grape culture is indispensable to the serious grower
Most grapes are self-fruitful; however, St Pepin requires a pollinator and should be interplanted with other cultivars. As with all self-fertile fruit varieties, they can benefit from some cross-pollination!
Grape plants should be spaced 6 to 8 feet apart, with 6 to 8 feet between rows.
How long before it fruits?
With proper cultivation and care, grape plants will start to produce in 3-4 years. This will vary with soil type and climate.
