How to Sow and Plant

Sow seeds directly into prepared soil in a sunny location after the last frost.

Scatter seeds lightly and cover with a thin layer of soil.

Water gently to keep soil moist until germination, which usually occurs within 7 to 14 days.

Thin seedlings once established to allow proper spacing for healthy growth.

How to Grow

Grow cosmos in full sun for best flowering.

Water moderately during early growth, then sparingly once plants are established.

Avoid excessive fertilization, as rich soil encourages foliage over flowers.

Deadhead spent blooms regularly to extend the flowering period.

Tips

Do not overfeed plants, as cosmos prefer lean soil.

Provide support in windy locations for taller plants.

Excellent choice for cut flowers due to long stems and long vase life.

Allow some flowers to go to seed for natural reseeding.
