Growing ProCut F1 Sunflower Garden Seeds

Sunflowers generally grow so hardy and vigorous that there is little reason to start seeds indoors. Sow ProCut seeds directly after final frost in a sunny spot at the north end of the garden and shelter from strong winds. However, for early spring blooming, start Procut seeds indoors 6-8 weeks prior. Seeds will take 7-14 days for germination. Early plants may need staking in addition to wind protection. For direct sowing, plant 2-3 ProCut sunflower seeds ½ inch deep and 12 inches apart in Organic, rich, and well-drained soil in full sun. Plants are heat and drought tolerant, but susceptible to mold and powdery mildew in poorly-drained soil. Monitor regularly for aphids, but ProCut Series sunflowers have no serious pests or diseases. Adjust staking and wind protection as plants mature. ProCut® Series sunflower seeds mature in as early as 50-65 days as 48-72 inch tall bushy uprights with a 12 inch spread and one 3-4 inch pollenless head circled in petals of sunburst, orange, gold, red, and mixed.

A common misconception about flowering Helianthus annuus heads is that they track the sun across the sky. Immature sunflower buds will exhibit this tendency, while mature heads are fixed throughout the day, generally facing an eastern direction. The leaves and foliage, however, will lean towards the sun for full light advantage.
