Sow seeds indoors 8 weeks before your last spring frost date in containers kept at 65-75°F. Scarify the seed coat using a file, rubbing about halfway around the seed to break through the hard shell. Expect germination in 14-28 days. Keep soil consistently moist until seedlings emerge.
Transplant seedlings outdoors about 2 weeks after your last spring frost, once soil has warmed and night temperatures stay reliably above 50°F. Harden off seedlings gradually over 7-10 days before moving them to their final location. Space plants 3 inches apart initially, though mature vines will need sturdy support structures.
You can sow seeds directly in place about 2 weeks after your last spring frost. Scarify seeds before sowing and keep soil consistently moist until seedlings establish.
Prune Corkscrew Vine after flowering ends in late fall to remove dead or tangled growth and shape the vine to fit your trellis structure. Light pruning during the growing season helps direct vigorous growth and encourages bushier flowering.
