Grape vines should be planted in early spring for the best results. Fall planting is not recommended because young vines are likely to be lost due to heaving. For grapes on a trellis, plants should be spaced 8 feet apart. For grapes on arbors, plants should be spaced 4 feet apart. An established and well-maintained grape vine will produce up to 40 pounds of grapes per year.
