The Best Way to Get Rid of Moss Between Patio Bricks


Nothing is more charming than a shaded brick patio with lush moss peeking through the crevices. The moss adds a classic, aged patina. Unfortunately, walking on that patio is downright dangerous because that moss becomes slippery when it's damp. Moss thrives in damp, shady conditions. Selectively prune trees and shrubs to promote more light and position sprinklers so they don't fall on your patio. But these measures probably won't completely prevent moss growth in wet climates.

Step 1

Scrub the moss with a stiff-bristled brush. Moss has no roots so it comes off easily.

Step 2

Make a solution of 1 part chlorine bleach to 9 parts water in a bucket.

Step 3

Scrub the bricks with the chlorine bleach solution to inhibit future moss growth.

Tips and Warnings

  • Test the chlorine bleach solution on an inconspicuous area on your patio before applying it. Don't use it if the bricks seem faded or discolored. Power-washing will remove moss, but can also damage bricks. Use power-washers on the lowest setting and don't point them directly at the bricks. Use a side-sweeping motion or call a professional.
