Maintain soil temp. of 70°F/21°C for about 5 days. Lower growing temp. to about 60°F/16°C. Transplant in 4 or 5 weeks, about the same depth as they were in the seedling flat. Maintain good air circulation, grow fairly cool @ 50°F/10°C after transplanting. Dense clusters of fragrant, brightly colored flowers will bloom in early June, the second season from seed.
DIRECT SOWING: Sow seed outdoors where the plants are to bloom any time from spring until mid summer, for flowers the following season. Thin seedlings to about 8 in/20 cm apart before they become too crowded. This species persists by self seeding. They like well drained sandy soil and require sufficient moisture during dry weather. Trim after blooming to encourage new growth. Use a fungicide to protect plants during humid weather.
