Cosmos are an easy to grow and beautiful addition to the cottage garden. Long stems make them perfect for flower arrangements and the wide variety of colors and flower shapes means there is definitely a variety for everyone.
Sow cosmos seeds into cell packs 6 weeks before the average last frost in your area. Cover the seeds lightly and keep moist. Transplant into the garden after danger of frost has passed.
Sow into the garden once the soil has warmed to around 60 degrees and all danger of frost has passed (mid-May in our area). Cover the seeds lightly and keep the area moist. Thin seedlings to about 12" apart after they emerge.
Tolerant of most soil types
Pinch young plants to encourage branching, which creates a fuller effect.
