Succulent & Cactus Soil

Soil Type

Water: Rock pine thrives in arid environments with exceptional drought tolerance, requiring watering only once every three weeks. This evergreen plant efficiently utilizes scarce rainfall, making it well-suited for outdoor growth in its native habitat.

Fertilize: Rock pine benefits from infrequent applications of Succulents And Cacti Food, ideally at half-strength quarterly during spring to fall. Cease feeding in winter to respect dormancy. Proper feeding promotes health, longevity, and enhanced coloration, preventing root damage and ensuring nutrient absorption.

Pruning: To maintain shape, large succulent plants like rock pine require pruning in spring and autumn, removing redundant or dense branches. For propagation, cut leaves in the same seasons, using a knife and applying sulfur powder on wounds before planting. Keep the cutting soil slightly moist.

Propagation: Rock pine is a hardy succulent that propagates well from cuttings. Cut healthy leaves or rosettes, allow the cut to callous, and plant in well-draining soil. Place in bright, indirect light and keep the substrate slightly moist to encourage root development and new growth.
