Growing Bright Lights Cosmos Seeds

Bee introduces how to plant

Sow Sulphur Cosmos: Sow seeds in cell packs or flats, 4 to 6 weeks before transplanting into the garden. Kept at 70 to 85° F., seedlings emerge in 7 to 21 days. Can direct sow Sulphur cosmos seeds after all danger of frost into prepared seed beds in rows, 4-6 seeds per foot. Thin seedlings to 10 to 15 inches apart. A less efficient but easier method of sowing cosmos: scatter seeds. Rake seeds into soil, keep area moist until germination.

Grow Sulphur Cosmos: Full sun. Best flower production is in soils of average fertility with moderate water. Sulphur Cosmos tolerate heat, drought, and poor soil. Remove spent blooms to promote additional flowers. Sulphur Cosmos will usually self-sow if some spent blossoms are kept on plants. Cut flowers typically last 5 to 9 days when blooms are cut as petals unfold. Flowers fully open in vase. Sulphur Cosmos attract birds, bees and butterflies and are rarely bothered by pests or disease.
