Are granite outdoor tree boxes resistant to discoloration from fertilizers?
Granite outdoor tree boxes are highly durable and resistant to many environmental factors, but their resistance to discoloration from fertilizers depends on the type and frequency of fertilizer use. Granite is a dense, non-porous stone, which makes it less likely to absorb chemicals that cause staining compared to other materials. However, prolonged exposure to acidic or chemical-heavy fertilizers may still lead to slight discoloration over time. To minimize this risk, opt for slow-release or organic fertilizers and rinse the surface regularly. With proper care, granite tree boxes can maintain their elegant appearance for years, making them a stylish and practical choice for garden decor.
