Caring for Scabious

Watering and Humidity

Scabious plants require regular watering, especially during their establishment phase. They are somewhat drought-tolerant once established, but consistent moisture is key to vibrant blooms. Be mindful of humidity levels, as scabious prefers a drier environment.

Sun and Temperature

These plants love the summer sun and need full sun exposure with at least 6 hours of direct sunlight daily. Ideal temperatures range from 55-65°F. They can tolerate both hot and cold temperatures but are sensitive to extreme heat and frost.

Pruning and Deadheading

Regular deadheading of spent flowers encourages more blooms and prolongs the flowering period. Cut back the plants in autumn to promote healthy growth in the following season.
