How to Grow Red Crimson Seedless Vine

Install a wire trellis system in a sunny location with well-draining soil in your landscape. Red crimson seedless grape vines grow best in full sunlight and produce a sprawling vine that requires a stable trellis system to support the weight of the large, heavy grape clusters.

Dig a hole 2 to 3 feet wide and 2 feet deep near one of the posts of the trellis system and mix in organic compost with the parent soil. Organic compost helps improve soil drainage and provides supplemental nutrients for developing red crimson vines.

Plant the young red crimson vine in the prepared planting site to the same depth as the nursery container. Plant the vines in early spring, after the risk of frost has passed, and ensure that the root collar of the vine is slightly above the soil surface.

Place a 2 to 3-inch layer of mulch around the base of the vine -- at least 3 feet in diameter -- to help retain soil moisture and prevent competition from weeds.

Water the vine daily until the roots are established and new growth is observed on the vine.

Train the developing vine to the wire trellis using twine to direct the shape of the vine. Space the vines so that there is plenty of space between each vine to improve air circulation and prevent disease.

Prune new growth that emerges from the base of the vine with pruning shears to focus plant growth on the vines and encourage grape production on the plant.
