Gardening Advice

Coreopsis is easy to grow and ideal for adding bright color to gardens. To enjoy beautiful blooms for a long time, keep the following points in mind:

Sunlight

Prefers sunny locations; full light promotes abundant flowering.

Watering

Drought-tolerant; avoid overwatering. Water generously only when the soil is completely dry.

Soil

Thrives in well-drained soil. Sandy soil or soil mixed with leaf mold works best.

Fertilizer

Heavy fertilization is unnecessary. However, during the blooming season, applying liquid fertilizer once a month helps extend flowering.

Pruning

Regularly remove withered flowers to encourage new blooms. Pruning improves the overall flowering performance.

Cold resistance

Many varieties are cold-hardy and can be grown even in cooler regions. However, varieties sensitive to frost should be kept in pots and moved indoors during winter.
