How to grow it
SCARIFICATION & STRATIFICATION: Open your Seeds In A Cup kit and remove the seed packet. Nick each seed coat lightly with a nail file or sandpaper, then soak seeds in warm water for 24 hours. Place the scarified seeds in the provided moistened growing medium inside a sealed bag. Refrigerate at 33-41°F (1-5°C) for 30-60 days.
PLANTING: After stratification, fill your Seeds In A Cup container with the provided growing medium. Plant seeds ½ inch deep. Water gently until moist throughout. Place in a warm, sunny spot (70-75°F) or under a grow light for 14-16 hours/day. Keep soil evenly moist. Germination typically occurs in 14-30 days.
SEEDLING CARE: When seedlings develop 2-3 sets of true leaves, gradually acclimate to outdoor conditions over 7-10 days (hardening off). Transplant to a permanent location with full sun and a sturdy trellis or arbor in USDA Zones 5-9. Water deeply once per week. Note: Wisteria may take 3-5 years from seed to first bloom. Prune annually in late winter for best flower production.
