How do grape vines grow naturally?

Wild grapes propagate by both seed and asexually. Birds and other wildlife eat the fruits. The hard seeds pass through their digestive system unscathed, ready to sprout wherever the creature leaves its droppings. The vines also produce roots and thus new plants when they touch the soil.

How much sun do grapes need?

Grapevines do best with full sun – about 7 or 8 hours per day. Less light leads to lower fruit production, poorer fruit quality, increased powdery mildew, and fruit rot.
