Sow seeds indoors in deep pots 4-6 weeks before your last spring frost date, keeping the soil temperature between 55-65°F. Once seedlings emerge, move them to cold conditions outside to harden off before transplanting into the garden.
Transplant seedlings out after your last spring frost date. Space plants 6 inches apart and ensure they have sturdy trellising nearby to climb.
Direct sow 3-4 weeks before your last spring frost date, planting seeds at a depth of 1/2 to 1 inch. Prepare the soil well with compost and aged manure before sowing.
Cut flowers regularly for arrangements once they open fully. Regular harvesting encourages continuous flowering throughout spring and summer, extending the bloom period from initial buds through late season.
