Vitis aestivalis

Summer grape (Vitis aestivalis) is a species of wild grape native to the Eastern United States and Canada. It grows up to 10-15 feet tall, with thin, deeply-lobed, and dark green leaves. Its small greenish-white flowers become deep purple or black, sweet, juicy fruits that ripen in midsummer. The fruits can be eaten fresh or processed into jelly, juice, wine, and syrup. Summer grapevines are fast-growing and hardy, tolerating a variety of soil conditions, drought, and light frost. A favorite of birdwatchers, they provide shelter, food, and nesting sites for migrating species.

watering

Summer grape plants require regular watering as they are very drought sensitive. During their growing season (spring to early fall), it is important to water the plants deeply and thoroughly once per week. Water the roots of the plants until the soil is moist to a depth of at least 8 inches. It is very important to establish consistent watering routine to ensure regular growth. During hot or dry spells, the plants may need additional water. If the soil appears dry, provide the plants with an additional, more shallow watering. To avoid over-watering, make sure the soil drains properly.

sunlight

The summer grape is a plant species that prefers a lot of full sunlight for optimal growth and production. It should be exposed to direct sunlight for at least 6-8 hours each day during the mid- to late-summer when temperatures are warm and the sun is at its brightest. Ideally, the sun should shine on the plant from morning until mid-afternoon, when the sun is most intense and the heat is at its highest. When nighttime temperatures are cool, a little shade from tall trees or buildings can help protect it from wind and cold. The summer grape can tolerate some shade but still needs full sun exposure throughout the day in order for its leaves, buds, and flowers to stay healthy. However, it is important to not expose the plant to too much hot direct sunlight for an extended period of time, as this can cause sunburn and leaf scorch.

pruning

Summer grape should be pruned twice throughout the year. In late-winter or early-spring, prune summer grape vines just before the new growth, cutting back to 15-20 leaves/buds. This revitalizes the vine and promotes healthy new growth. In summer, selectively prune off any shoots that are overgrown, crossing, or dead to keep the vine in bounds. This will encourage more air flow and sunlight for the entire vine. In addition, remove any suckers or other unwanted vines at this time.
