Start indoors in a well-lighted area about 6-8 weeks before last frost. Sow seeds 1/4" deep in seed-Starting formula. Keep evenly moist.
How to Grow
Seedlings emerge in 10-20 days 60-65°F. Transplant hardened-off seedlings to the garden after all danger of frost. Stock prefers rich, well-drained soil and full sun. Taller cultivars may need staking, although the stems are generally strong. The plants require cool temperatures to flower and will not form new blooms when temperatures rise above 65°F.
Stock is useful for beds, borders, and containers, but it is best grown for cutting and for its exquisite frangrance. Grow tall cultivars in a cool greenhouse for winter cut flowers.
