GREENHOUSE: Sow Mar. 1st for perennial sales. Germinate @ 60°F/16°C soil temp. for 20 days. Cover seed lightly, 1/4 in/6 mm deep, and firm. High soil temps. will limit germination. Maintain air temp. of 65°F/18°C days and 55°F/13°C nights for about 2 weeks. Grow seedlings @ 50°F/10°C to prevent soft, spindly growth. Transplant into 2 1/4 in/6 cm peat pots, about 6 weeks after seeding. When transplanting - use all sizes of seedlings. Do not sort seedlings according to height, or you will end up sorting out each color. Whites and pinks are the most vigorous. The reds, salmons and yellows are usually the smaller ones.
DIRECT SOWING: Sow outdoors as above, from May to July. Space plants 12 in/31 cm apart. Keep plants sprayed with a fungicide to prevent "rust" disease, which attacks the foliage (especially double types). Most double flowered varieties attain full bloom the second season. Double-ness increases to almost 100% the following spring.
