How to Sow and Plant

Prepare well-drained soil and sow seeds directly outdoors after the last frost.

Scatter seeds lightly and cover with a thin layer of soil, about 0.5 cm deep.

Water gently to keep the soil moist until germination occurs.

Seeds can also be started indoors 4–6 weeks before transplanting.

How to Grow

Grow cosmos in full sun for best flowering.

Water moderately, allowing soil to dry slightly between watering.

Avoid excessive fertilization, as this encourages foliage over flowers.

Deadhead spent blooms to promote continuous flowering throughout the season.

Tips

Do not over-fertilize; cosmos prefer lean soil.

Pinch young plants for bushier growth.

Allow some flowers to go to seed for self-sowing.
