Grape 'Mars Seedless' blue (Patent #5680)
Item GR130

Grow Your Own Fresh Fruit!
'Mars' (Plant patent 5680), a release from the University of Arkansas, is a vigorous, blue seedless grape that tolerates hot, summer areas. 'Mars' Seedless withstands powdery mildew & black rot! The flavor is mild and delicious for fresh eating. The berries are slipskin (having a tough skin that separates readily from the pulpy flesh). Clusters are medium sized, cylindrical, and well filled. Grapes are not particular about soil preference and do especially well in clays and loams that have been improved with organic matter.

The vines are allowed to run as they will the first year and the posting or staking is done the second or third year when you will prune heavily, leaving only 2 or 3 buds on the strongest stem. As it grows you’ll keep only the most vigorous sprout to form the main stem. Shallow cultivation and mulching are beneficial.

Pests: Grapes are high maintenance plants that require regular chemical spraying and pruning. Grapes are susceptible to a large number of diseases, particularly in humid summer climates, including anthracnose, black rot, downy and powdery mildew, crown gall and botrytis bunch rot. Insect pests include phylloxera, grape berry moth, Japanese beetle, leaf hopper, leaf roller, mealy bugs and flea beetles.

Notes: 'Mars' has been recommended in Arkansas as a home garden grape with limited potential for commercial marketing. 'Mars' has a Concord-like flavor. The blue fruit are borne on medium size well-filled clusters, and keep well. Very productive. Hardiness has been good and the vines are resistant to several major diseases. Vines may bear fruit precociously, and production should be controlled on young vines to prevent delays in establishment.

Grapes are primarily grown for fruit production in home fruit gardens where ornamental interest is not a concern. However, grapes do in fact have good ornamental value: bold summer foliage, some fall color, showy fruit and shaggy, twisted trunking and branching often best seen in winter. When grown on fences, walls, trellises, arbors or other structures, grapes can be quite attractive year-round and can provide good cover, screening, or shade to areas around the home.

Planting instructions: May be planted in any well-drained soil. Dig a hole large enough to encompass the roots without bending or circling. Set the plant in place so the crown (part of the plant where the roots meet the stem) is about 1-2" below the soil surface. Cover with soil to the original soil surface and water thoroughly. Fertilize when planting.

Best grown in deep, loamy, medium wet, well-drained soils in full sun. Tolerates a wide range of soil conditions, including average garden soils, but must have good drainage. Best sited in a location sheltered from winter winds (preferably a southern facing slope) and well removed from frost pockets. Self-pollinating. Grapes need a support system, training, regular spraying and regular pruning to maximize fruit production.
