Gardening Advice

Chocolate cosmos can provide long-lasting blooms if grown under proper conditions.

Sunlight

Prefers full sun. It can grow in partial shade, but insufficient light reduces flowering.

Watering

Likes moderate moisture but is sensitive to overwatering, which causes root rot. Water when the soil surface has dried.

Soil

Requires well-drained soil. A light mix with compost or perlite promotes healthy growth.

Fertilizer

Apply slow-release fertilizer once a month during the growing season. Excess fertilizer encourages leaf growth over flowers.

Wintering

In cold climates, it is sensitive to frost. Keep it indoors in pots during winter or dig up and store the tubers.
