How to I kill moss growing between patio stones? How to I kill moss growing between patio stones?

Patio stones are susceptible to moss growing between them due to the perfect growing conditions of moisture and heat. Usually, a power washer will remove the moss due to its short root system. To be certain that it has all been killed, mix 1 cup of powdered laundry detergent with a ½ cup of liquid bleach in a bucket of hot water. Stir until the powdered detergent has dissolved. Pour on the moss, and just leave it. It will kill the moss and deter growth of new moss forming.
