Seeing green algae coat your garden benches can be frustrating, especially in damp, shaded areas. Don't worry—this common issue has simple, effective solutions. First, for a natural clean, mix equal parts white vinegar and water in a spray bottle. Generously apply it to the affected areas and let it sit for 15-20 minutes. The acetic acid breaks down the algae. Then, scrub the surface with a stiff-bristled brush. For tougher growth, a solution of oxygenated bleach (following package directions) is highly effective and safer for plants than chlorine bleach. Rinse thoroughly with a garden hose. To prevent regrowth, improve air circulation by trimming nearby foliage. Applying a water-repellent sealant for outdoor wood or metal can also create a protective barrier. Regularly wiping down benches after rain or dew removes the moisture algae needs to thrive. With these steps, your benches will stay cleaner and brighter, reclaiming your peaceful garden space.
