How can moss growth on stone outdoor planters be controlled without damaging the surface?

Moss growth on stone outdoor planters can add a rustic charm but may become unsightly or slippery over time. To control moss without harming the stone surface, follow these methods:

1. Vinegar Solution: Mix equal parts white vinegar and water, spray on moss, and scrub gently with a soft brush. Rinse thoroughly to prevent residue buildup.

2. Baking Soda Paste: Apply a paste of baking soda and water to mossy areas, let sit for 15 minutes, then scrub and rinse.

3. Preventive Measures: Ensure proper drainage and sunlight exposure to discourage moss regrowth.

4. Natural Herbicides: Use eco-friendly moss killers containing citric acid or potassium salts for stubborn growth.

Avoid harsh chemicals or pressure washing, as they can erode the stone. Regular maintenance keeps planters moss-free while preserving their beauty.
