It's Easy to Plant & Care for Your Summit Muscadine Grapes
Summit muscadine grapes are bronze-gold in color and sweet to the taste. They are so delicious, you won’t be able to get enough! This variety is known as Vitis rotundifolia and will need a pollinator to fruit. These grapes perform their best in USDA growing zones 7-10 in full sun. Summit Muscadine Grapes are fast growers, maturing to a height of 12 feet tall and 5-8 feet in width.
Location: When planting summit muscadine grapes, find a location that offers full sun and moist, well-draining soil. Avoid shaded areas as fruit set/production will be reduced in the absence of sun during the growing season. Muscadines are a vine and will require some type of trellis to grow on properly.
Planting Instructions:
1) Dig your hole 3 times the width and slightly shallower than the root ball.
2) Loosen the soil, in and around the hole so the roots can easily breakthrough.
3) Use your fingers to separate the roots of your summit muscadine vine and gently position downward in the hole. The top of the root flare (where the roots end and the trunk begins) should be about an inch above the surrounding soil.
4) Begin to backfill the site, tamping down the soil as you go.
5) Apply water to settle the soil and remove any air pockets that may have formed then mulch to retain soil moisture.
Watering: Water regularly for the first year by giving your plants about 1 inch of water (1-2 gallons) a week. Directly moisten the roots but avoid spraying or misting the grapes. After the vines are a bit more established, they will seldom need watering. Be watchful for leaf drop, this is an early warning sign that you may be overwatering.
Pollination: Most species of grape are self-fertile but a good rule of green thumb is to always plant in pairs. This will assure you a healthy yield of fruit come harvest time.
Fertilizing: Apply a 1/4 pound of formula 12-12-12 or 10-10-10 fertilizer in an 18-inch circle around each vine in April. Re-apply every 6 weeks until July during the first year of growth. In the second year, apply fertilizer in March, May, and July increasing the dose to 1/2 pound per vine. Be sure the fertilizer is not closer than 21 inches from the trunk.
Pruning: Balanced pruning maintains the vine’s form, size, vigor, and next season’s fruiting wood. Pruning should be done when the vines are dormant in late winter or early spring. Do not prune when vines could freeze, because the new growth can be brittle and can damage easily. The foliage around the grape clusters can be removed to expose the fruit to sunlight in a short growing season. During your first growing season, multiple shoots will begin to grow and the vine may become bushy. Some trim their plants back to just one or two shoots. Others prefer to let them grow so they may have a better selection to choose from during the following winter’s pruning.
Harvesting: Taste is the best determining factor if it’s time to harvest or not. When fruit appears. Test its ripeness by picking a few grapes from different areas and tasting them. If the grapes are sweet, start picking as they ready for harvesting.
Tips:
*Grapes will not continue to ripen after picking so be sure not to pick them too prematurely.
*Color and size are not necessarily good indicators of ripe fruit. Only pick the fruit after you’ve tasted it and are certain it is ready.
