The fruit of Mars is blue, round, and seedless. Berries are medium to large in size. Vines are hardy. A disease resistant table grape. Ripens early.
Bare-root grapes vines are best planted in springtime. Dig a hole that is twice as deep/wide as the root system of your grapevine, at the base of a trellis post. Place the bare-root vine in the hole and fan out its roots. Place the root-ball so that the area where its roots begin on the trunk is about 1” below the soil line. Back-fill the hole ¾ of the way full, then water to settle the soil. Add remaining soil to fill the hole to ground level, and water once more.
