Triumph Muscadine Grapevine

The Triumph Muscadine grapes are pink-ish, bronze grapes that are sweet with a pleasant “crunch” texture. This type of grape is quite popular for wine making as well as eating fresh right off of the vine. This variety known as “Vitis rotundifolia” performs best in USDA growing zones 7-10 in a full sun location. Triumph muscadine grapes are fast growers, maturing to a height of 12 feet tall and 5-8 feet in width and with most grape varieties, will need a trellis or wire support to properly grow. The grape vine is self-fertile and therefore will not require a pollinator in order for the fruit to set.

Location: When planting triumph 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 break through.
3) Use your fingers to separate the roots of your triumph 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 over watering.

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. 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.
