EASIEST TO PLANT OUTDOORS

Plant in full sun in good garden soil only when weather is warm and settled, all danger of frost is past and both days and nights are evenly in the 50°F (10°C) range. Poke individual seeds into well-worked soil about 1/2 in. deep, 4 to 5 in. apart. Press the soil firmly over the seeds and keep the seedbed evenly moist until seedlings emerge in 8 to 10 days.

Important: when the seedlings are well-established, carefully thin them to a final spacing of 1 foot apart; this way they will have enough room to develop sturdy stalks that won’t blow over and big clusters of flowers. Any extra seedlings you need to remove can be transplanted elsewhere in the garden or potted up and given to friends.

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 well established and ready to plant outside. Transplant carefully, disturbing the roots as little as possible. Space seedlings 1 foot apart so plants will have room to grow and mature.

GROWING NOTES

Growing these colorful sunflowers for pollinators and bouquets is both easy and rewarding. Make several sowings several weeks apart and you’ll have a succession of flowers in full bloom. Keep soil moist and well weeded. Protect very young seedlings from bird predation by covering the bed with bird netting held tautly well above seedlings by supports. Or use plastic berry baskets, removing before plants get crowded.
