Coreopsis ‘Zagreb’ Care

Planting: Choose a location with full sunlight for your Coreopsis ‘Zagreb’. Ensure well-drained soil, as soggy conditions can lead to root rot. Space plants about 12 to 18 inches apart.

Watering: Water regularly during the first growing season to establish a strong root system. Once established, ‘Zagreb’ Coreopsis is drought-tolerant and only requires watering during prolonged dry spells. Water at the base of the plant to avoid wetting the foliage, which can lead to disease.

Soil: Coreopsis ‘Zagreb’ prefers well-drained soil of average fertility. It can tolerate poor soils but thrives in amended soil with organic matter such as compost.

Mulching: Apply a layer of mulch around the base of the plant to conserve moisture, regulate soil temperature, and suppress weed growth. Keep the mulch a few inches away from the plant’s stems to prevent rot and disease.

Fertilizing: ‘Zagreb’ Coreopsis generally does not require fertilization. However, if the soil is poor, you can apply a balanced, slow-release fertilizer in spring.

Pruning: Deadhead spent flowers regularly to encourage continuous blooming throughout the growing season. Cut back the entire plant to about half its height after the first flush of blooms to encourage a second round of flowering.

Division: Every few years, divide overcrowded clumps of Coreopsis ‘Zagreb’ in spring or fall to rejuvenate the plant and maintain vigor.

Protection: Coreopsis ‘Zagreb’ is generally resistant to pests and diseases. However, monitor for common issues such as aphids or powdery mildew, and treat promptly if necessary with insecticidal soap or fungicide.
