Growing Instructions

Planting Season: Sow in spring after the danger of hard frost has passed. Some Coreopsis species can also be fall sown in suitable climates.

Sowing: Prepare a fine, weed-free seedbed and sow seeds directly onto the soil. Press them gently into the surface.

Depth: Cover seeds with approximately one-eighth inch of soil.

Spacing: Thin seedlings to approximately twelve to eighteen inches apart, depending on the mature size of the variety.

Sunlight: Provide full sun for strong growth and abundant flowering.

Soil: Choose loose, well-drained soil with moderate fertility. Avoid excessively rich or poorly drained soil.

Watering: Keep soil lightly moist during germination and early establishment. Once established, water when the soil begins to dry.

Germination: Seeds commonly germinate within approximately seven to twenty-one days under favorable conditions. Temperature and moisture can affect germination time.

Transplanting: If starting indoors, transplant young seedlings carefully once they have developed several true leaves and outdoor conditions are suitable.

Fertilizing: Heavy fertilization is generally unnecessary. If the soil is poor, apply a balanced fertilizer according to the product label.

Care: Keep young plants free from weeds and provide adequate spacing for airflow. Deadhead spent flowers to encourage additional blooms.

Flowering/Maturity: Coreopsis commonly begins flowering from late spring into summer. Exact flowering time varies according to species, planting season, climate, and growing conditions.
