Summer/fall bloom
Frost tender
TO START DIRECTLY IN THE GARDEN
Sow seeds in well-worked soil in full sun when danger of frost is past and temperatures are above 50°F (10°C) both day and night. Space seeds 2 to 3 inches apart in rows 12 inches apart, cover about 1/2 inch deep and gently firm soil. Keep evenly moist while awaiting germination.
TO START EARLY INDOORS
Four weeks before last frost date, sow seeds 1/2 inch deep and 3 inches apart in containers of seed starting mix. Keep warm and moist and provide a strong light source. Feed with 1/2 strength fertilizer every 2 weeks. Just as soon as seedlings have several sets of true leaves, plant outdoors when temperatures stay above 50°F (10°C) at night.
THIN OR TRANSPLANT
Space seedlings 8 to 10 inches apart when large enough to handle to provide good air circulation and give plants room to mature.
GROWING NOTES
Zinnias grow readily in ordinary garden soil in full sun. Be sure to thin before seedlings get crowded; adequate spacing and regular even watering help keep zinnias productive and disease free. Grow colorful Persian Carpet in beds or borders, or combine with white alyssum, dwarf marigolds, petunias and salvia for season-long bloom in terracotta pots and color bowls.
