I have a brick paver patio. It gets indirect sun. Moss grows in between the bricks. It is not really horrible, but I don’t like it. What I am looking for is something I can mix in a bucket, toss it over the patio, spread it out with a broom and voila, kills the moss. I really do not want to stand there all day and squirt a stream of stuff until my forearms get vascular. Did I ask this last year?
