Growing these colorful flowers is easy and rewarding. Make several sowings 3 weeks apart to have a succession of flowers in full bloom. Keep soil moist and well weeded and protect seedlings from birds with netting or plastic berry baskets, removing before plants get crowded. Be sure to thin properly when seedlings are about 3 inches tall.
TO START EARLY INDOORS
Several weeks before last frost date, sow seeds 1/2 inch deep in individual pots of well-drained seed starting mix. Keep moist and provide a strong light source until seedlings are ready to plant outside. Transplant carefully, disturbing the roots as little as possible.
