Gardening Advice

Proper care will ensure that chocolate cosmos thrives and blooms beautifully.

Sunlight

Prefers full sun but can tolerate partial shade. However, insufficient sunlight may result in fewer flowers.

Watering

Soil

Well-draining soil is ideal. Mixing compost or perlite into the soil can improve growth.

Fertilizer

Apply slow-release fertilizer once a month during the growing season. Over-fertilization may lead to excessive foliage growth.
