Moss on patios can be eliminated in just five minutes using a common kitchen ingredient, according to a homeowner who tested the method. Baking soda works by dehydrating the moss and altering the patio's pH level to prevent regrowth.
The baking soda method
The technique involves sprinkling baking soda directly onto moss patches after brushing away loose dirt. The moss turns brown within 24 hours and dies without the need for scrubbing or harsh chemicals.
The homeowner, Katherine McPhillips, shared her experience after learning the trick from a neighbor. She was initially skeptical but found it effective after trying it in late July. She now spends less than five minutes treating her patio and sees results within a day or two.
Why it works
Baking soda is highly absorbent, drawing moisture from the moss and dehydrating it. Additionally, its alkaline nature raises the pH level of the patio, making it harder for moss to re-establish.
McPhillips notes that the process requires patience, as the baking soda needs at least 24 hours to break down the moss. However, she prefers this natural method over chemical products, especially since she has a dog that sniffs around the garden.
Application tips
Before applying, check the weather forecast to ensure dry conditions, as rain will wash the baking soda away. Brush the patio with a stiff broom to remove loose dirt, then sprinkle a generous amount of baking soda on any green or black spots. Leave it for at least two hours, ideally overnight, then rinse with water.
The moss should come off easily without scrubbing. For heavy infestations, the process may need repeating, but typically this five-minute task keeps patios moss-free through summer and autumn.
