Seeds can be stated early indoors in late winter to early summer or can be sown directly outdoors where they are to flower. Seeds can be also sown in autumn, they make fine spring flowering pot plants for the cool greenhouse. 65 days sowing to flowering. 
 
Sowing Direct: 
Choose a sunny, well-drained site, and amend it with compost or well-rotted manure. Direct sow ¼" deep in spring, as soon as the ground can be worked. Pinch seedlings when they are 3" tall to promote branching, and thin to 8in apart. Maintain soil moisture all season, and fertilize monthly with a water-soluble fertilizer, following label directions. 
 
Sowing Indoors: 
Sow in spring about 5 to 7 weeks before the last frost date (around May). Sow 1/16" deep in into pots or trays containing John Innes or similar free draining seed compost. Make sure that the compost is moist but not wet and cover or seal in a polythene bag, exclude light until after germination which usually takes 10 to 21 days at 55- 60°F. 
Transplant when large enough to handle into 8cm (3in) pots to grow on.
Pinch out the growing points when 3" high to ensure a bushy habit. 

Annual phlox seedlings should be hardened off before transplanting to the garden. Put them outdoors in a sheltered spot for a few hours each day, gradually increasing their time outdoors over the course of a week. Plant out 20cm (8in) apart into rich well drained soil and full sun.
