Find a growing area that receives full sun, as Candice grapes thrive in ample sunlight. Plant in loamy soil with a pH ranging from 5 to 5.5 for best growth. While these hardy grapes grow in many soil types, they do best in loamy soil.
Dig post holes approximately 2 feet deep and spaced 20 feet apart to start a grape trellis. Use 8 feet long posts that are about 3 to 4 inches in diameter, as recommended by North Carolina University Cooperative Extension. Ensure they are straight and pack the soil around the posts.
Tie 12-gauge trellis wire along the posts. Wrap the wire around each post tightly to make sure it can hold the weight of the grape vine.
Plant each grape plant in early spring about 5 to 8 feet apart. Trim off any dead roots before placing the plants into the holes.
Spread 1/2 cup low-nitrogen fertilizer around the base of each plant without allowing the fertilizer to come in direct contact with the base of the plant. Water the plants thoroughly and keep the soil moist during the first year for optimal growth.
Fertilize the plants once a year with a low-nitrogen fertilizer. Add fertilizer to the plants according to the package directions.
Prune all weak shoots from the vines as they grow to allow the strong shoots to travel up the trellis.
Harvest the grapes as they mature, which is typically late summer. Candice grapes will usually continue to produce fruit throughout early autumn.
