Concord grapes are one of the most popular varieties of grapes in the United States. They are known for their sweet flavor and deep blue color and are often made into wines and juices. Concord grapevines are winter hardy and relatively disease tolerant. The most effective way to grow large amounts of fruits is growing your concord grapevine into a tree formation. When grown this way, it can reach 12 to 46 inches tall and produce fruit for many years.
Use cuttings from dormant vines collected in December or January or purchase a young grapevine from a nursery. Cuttings do best when dipped in growth hormone and allowed several months to grow roots before planting.
Choose the right location. Concord grapes need eight hours of sunlight a day to grow. Find an area with well-drained soil on the southern side of a slope or building.
Prepare the soil. Dig a hole as deep as the container and wide enough to spread the root system without bending any roots. As you dig, mix the original soil with 50% compost or 50% perlite.
Plant your grapevine. For a cutting, bury the bottom three nodes in the soil mixture and allow the upper one to two buds to show above ground. For a young plant, be sure the roots are not buried too deep—no more than 2 inches below ground.
Water immediately. After planting, fully soak the soil with an open hose. Continue to water your plants every one to three days without allowing standing water to accumulate.
As your vine grows, tie it to a firmly planted stake to ensure a single, straight trunk. You may have to adjust your tie as the plant gets larger.
Remove any dead or dying leaves throughout the year. During colder months, prune any lower shoots or leaves that may emerge and allow growth only on the uppermost part of the vine. This will shape your vine into a tree and provide maximum fruit production.
