Muscadine Grapes

Soil

Grapes are not as particular to soils as other fruit crops; rich soils stimulate excessive vine growth at the expense of fruit quality. Grapes require a soil pH of 5.5 to 7.0.

Varieties

All of these cultivars are perfect flowered (male and female flower parts), so a single vine will be fruitful.

Planting

Plant at the same depth or slightly deeper than the previous planting depth. Vines should be a minimum of 8 ft apart in the row. Distance between rows can depend on the equipment used for mowing, but 8 ft should be a minimum.

Fertilization

Apply ¼ lb of 10-10-10 in an 18-inch circle around each vine after planting (late April to early May). Repeat every 6 weeks until early July. The second year, apply in early March and May at double the first year's rate (½ lb per vine). Do not put the fertilizer closer than 21 inches from the trunk. For mature vines, scatter 1 to 2 lbs of 10-10-10 uniformly under the vine (60 to 120 sq ft) in early to mid-March and apply another 1 lb in mid-June. Avoid mulching materials that will release nitrogen late in the season and cause increased susceptibility to winter damage.

Weed Management

Keep an area 1 to 2 ft in diameter around each vine free of weeds by shallow cultivation for the first 2 years. A coarse, non-nitrogen-releasing mulch such as bark will also help control weeds and reduce moisture loss from the soil.

Irrigation

Muscadine grapes are quite drought tolerant. Water during dry periods the first two years, then the vines can usually obtain adequate water from the soil even during dry periods.
