Garden Soil

Soil Type

Water: Adapted to rocky, cold environments, moss campion requires minimal water, thriving with a watering schedule of once every 1-2 weeks. Preferring well-draining soil, it suits outdoor rock gardens and conserves water in its dense foliage, enhancing its survival and flowering potential during the short alpine growing season.

Fertilize: For moss campion, use balanced fertilizers or high phosphorus options in early spring and midsummer at half-strength. Apply a quarter teaspoon per gallon of water, avoiding over-fertilization. Adjust frequency as moss campion transitions from active growth to dormancy, ensuring robust health and vibrant blooms.

Pruning: Moss campion is a mat-forming perennial with dense growth and pink flowers. Light pruning in early spring to late winter removes dead stems and encourages health. Regularly snipping spent blooms promotes further flowering, ensuring vigorous growth and an attractive appearance.

Propagation: Moss campion is best propagated through cuttings from healthy non-flowering shoots. Place cuttings in well-draining soil with ample indirect light and stable moisture. Using rooting hormone and ensuring good air circulation helps reduce rot and disease risks, enhancing propagation success for this cushion-forming perennial.

Repotting: Repot moss campion every 2-3 years in spring, using shallow, wide containers. Choose a pot one size larger to avoid waterlogging. After repotting, maintain even soil moisture and place in a cool, sunny spot for optimal recovery.
