A pH in the range of 5.5 to 7.0 is ideal for most varieties. Grapevines will flourish with a reasonable amount of sunshine, but they will need full sunshine in most cases to produce grapes with a high enough sugar content to produce wine. The pigmentation and ripeness of grapes is a product of the sun shining on the leaves of the vine. Depending on the variety you plant, you can generally expect 10,000lbs. per acre. Potted grapes can be planted at any time, but bare root grapes must be planted while the vines are still dormant.
Late fall is when most suppliers ship bare rooted vines.
Fertilize in early spring and again about a month later, but do not fertilize past mid summer. Your vines need to enter dormancy at a normal time in fall or they will receive greater than normal winter damage. Grapevines should only be watered when they are initially planted, during the first few weeks after planting, and thereafter only in time of extreme drought. Over watering will cause many varieties of grapes to split, and water too often on the leaves of the vine can cause problems with a variety of fungus diseases. Always apply water to the base of the vines only.
