How to prevent algae growth on granite flower boxes in shaded areas?
Granite flower boxes add elegance to any garden, but shaded areas can encourage unsightly algae growth. To prevent this, start by ensuring proper drainage to avoid water accumulation, as stagnant moisture promotes algae. Regularly clean the granite surfaces with a mixture of water and white vinegar or a mild bleach solution to kill existing algae and deter regrowth. Applying a sealant designed for granite can create a protective barrier, making it harder for algae to take hold. Additionally, trim nearby foliage to increase sunlight exposure and improve airflow, reducing damp conditions. For long-term prevention, consider using algae-resistant granite or periodically repositioning the flower boxes to sunnier spots. These simple steps will keep your granite flower boxes looking pristine year-round.
