Grape Mars Seedless

Grape 'Mars' Seedless

The Grape ‘Mars’ Seedless (Vitis labrusca ‘Mars’) is a reliable, American-bred seedless grape variety developed by the University of Arkansas. Renowned for its sweet, mild flavor and crisp, juicy texture, ‘Mars’ grapes grow in tight clusters and ripen to a deep blue-purple. This variety is perfect for fresh eating, juicing, or making jelly and is an excellent choice for backyard gardeners due to its low maintenance and high disease resistance.

‘Mars’ is a vigorous, self-pollinating vine that grows rapidly and produces abundant fruit typically by its second or third year. It’s highly resistant to common grape diseases such as black rot and powdery mildew, making it a preferred choice for organic growers and those seeking a low-spray option. This cold-hardy variety thrives in USDA Zones 5–8 and performs well when trained on arbors, fences, or trellises, offering both fruit and ornamental value.

With its combination of great taste, ease of care, and decorative appeal, ‘Mars’ Seedless is ideal for gardeners looking to grow grapes without the hassle of seeds or high pest pressure.

Care Instructions

Planting:
Plant in full sun with well-draining soil. Space vines 6–8 feet apart. Install a trellis or arbor at planting time for support.

Watering:
Water deeply once per week during dry periods. Avoid overhead watering to reduce fungal risks.

Pruning:
Prune annually in late winter to control growth and maximize fruit production. Remove old canes and train new ones.

Pest Control:
Generally disease-resistant, but monitor for Japanese beetles and aphids. Use neem oil or insecticidal soap if infestations occur.

Soil Tips:
Prefers slightly acidic to neutral soil (pH 6.0–7.0). Improve drainage with compost and avoid over-fertilizing, which can reduce fruiting.
