Growing Shock-O-Lat Sunflower Seeds

Bee introduces how to plant

Plant Sunflower Seeds: Direct sow into prepared seed beds after all danger of frost. Plant seeds 6 in. apart, ½ in. deep. Thin to 1-1½ ft. apart. Can start plants early indoors in 2 in. pots or cell packs. Transplant into the garden well before seedlings become root bound.

Grow Sunflowers: Sunflowers require full sun. Soil which is moist and moderately fertile will produce the best flower heads. Blooms attract bees, birds and butterflies.
