Planting & Care
Sow Diablo Cosmos seeds directly outdoors after the last frost date, or start them indoors 4–6 weeks before transplanting. Press seeds lightly into the soil surface and keep evenly moist until germination, which typically occurs in 7–21 days at 65–75°F. Thin seedlings to the recommended spacing to encourage strong, bushy growth.
Once established, cosmos require little care. Water during dry spells and deadhead spent blooms to prolong flowering. Tall plants may benefit from staking in windy areas. Avoid over-fertilizing, as rich soil can promote excessive foliage at the expense of flowers.
