Vitis labrusca, the Concord grape, thrives in United States Department of Agriculture hardiness zones 4 to 9 and is indigenous to the United States. This grape variety is prized because of its flavor, which makes it perfect to use in jellies and homemade jams or to eat straight from the vine. As with numerous vine varieties, the Concord grape requires a sturdy structure. Training the Concord grape vine across the fence is an ongoing process which requires continued monitoring of growth over the first few years.
Analyze fence and your lawn to find out if the placement and structure is suitable to encourage the Concord grapes. The grapes need full sun and fertile soil during the day to thrive. The fence have articles, and has to be sturdy, constructed from wood or metal. If an existing fence is found in an area that receives full sunlight and suitable, amend any soil with a layer of compost. Work the compost.
If there isn’t one gift, Build a wood or metal fence enough to encourage the grape vines. Insert 8-foot metal or wood posts into the ground at least 2 feet deep in intervals. Insert eye-hole screws into each pole at 18 and 36 inches above the ground. Stretch 12- or 13-gauge cable across and wrap the ends through the eye holes, then pulling the cable taut. If you’re using an existing fence to encourage the Concord grape blossom, install the screws and cable in precisely the same fashion.
Dig a hole slightly bigger than the Concord grape’s root ball . Set them, if planting vines. Plant vines grown from cuttings well beneath the soil to ensure the root ball is completely covered. Plant grafted vines so the root ball is right beneath the soil surface. Refer to the label to find out if it had been grown from cuttings or grafted of the plant. Repeat this process with all the remaining Concord grape vine seedlings.
Backfill the hole and provide each Concord grape seedling with enough water to completely saturate the soil but not create a mess. Continue to monitor the grape seedlings during the first year of growth and provide enough water to saturate the soil once it dries out. They need water once the Concord grape plantations are well-established.
Permit the Concord grape vine to develop into the fence to the first growing season. According to the University of California, this allows the root system to become well-established and powerful. If any of the strongest shoots of the vine grow rapidly during that season and get to the wire, tie it loosely and up with a piece of string. Avoid using cable as this can damage the shoot.
Continue to monitor the Concord vine; prune it back just once the most important shoot grows 6 to 12 inches over the top cable. This may create by procuring each new shoot into the cable loosely with series at least two shoots, which should be trained in reverse directions.
