Care Instructions

Watering: Maintain consistent soil moisture, especially during the first growing season and hot summer periods. Water at soil level rather than overhead to prevent crown rot and fungal issues. Once established, shows moderate drought tolerance but performs best with regular watering.

Pruning: Remove spent flower stems to encourage continued blooming and maintain tidy appearance. Cut back any damaged or brown foliage in late winter before new growth emerges. Divide clumps every 3-4 years in spring to maintain vigor and prevent overcrowding.

Fertilizing: Apply a balanced, slow-release fertilizer in early spring or use compost as a soil amendment. Avoid high-nitrogen fertilizers which can reduce foliage coloration. Add a thin layer of organic mulch to retain moisture and suppress weeds while providing gradual nutrient release.
