Garden patios often become covered in moss, but a simple kitchen ingredient can effectively remove it. Bicarbonate of soda, also known as baking soda, is a common household item that can kill moss without harsh chemicals.
How Bicarbonate of Soda Works
Bicarbonate of soda creates an alkaline environment that moss cannot tolerate. It also draws moisture out of the moss, causing it to dehydrate and die. This method is slow but effective, typically taking 24 hours to a few days.
Step-by-Step Application
- Dampen the moss with water or wait for a damp day.
- Sprinkle bicarbonate of soda generously over the mossy areas.
- Use a broom to brush the powder into the moss for even coverage.
- Leave it for at least 24 hours until the moss turns yellow or golden.
- Scrape away dead moss with a stiff brush or broom.
- Rinse the patio with water to remove residue.
Expert Tips for Best Results
For persistent moss, repeat the process. Avoid heavy runoff onto grass, as bicarbonate of soda can act as a weed killer. If a white chalky residue remains, scrub with warm soapy water and rinse again. Bicarbonate of soda does not stain stone; it only removes dirt and leaves a harmless powder.
This method is a safe, eco-friendly alternative to chemical moss killers. For stubborn cases, consult a gardening expert.
