Garden Soil

Soil Type

Water: Originating from the Pacific islands, pacific island silvergrass thrives in humid, tropical conditions. It prefers consistent moisture, requiring weekly watering. Once established, it is moderately drought-tolerant. Indoors, pacific island silvergrass enhances decor but needs careful watering to maintain its vibrant foliage and avoid soil dryness.

Fertilize: Pacific island silvergrass requires balanced fertilizers containing equal nitrogen, phosphorus, and potassium, applied quarterly during the growing season. Increase application frequency while active but reduce during dormancy. Use slow-release fertilizers, water after application, and follow safety guidelines for optimal growth and root protection.

Pruning: To promote healthy growth of pacific island silvergrass, prune in early spring by cutting back last season's growth to 6-8 inches (15-20 cm). This enhances air circulation, reduces disease, and encourages blooming while maintaining a neat appearance and preventing density that limits sunlight access.

Propagation: Pacific island silvergrass is propagated through division during its dormant period to reduce transplant shock. Ensure sections have sufficient roots and shoots for reestablishment. Use sharp tools to cut cleanly, and plant divisions at the same soil depth as the parent. Consistent watering aids establishment.
