Moss Control in Beds

Q. This year I had lots of moss in my flower garden. Although I have had
patches of moss on other places before, I don’t remember much in my
garden areas. It’s gone now, having had my bed cleaned up for the
winter, but how do I keep it from coming back or killing it if it
does, without hurting my flowers? Sure miss your column in the Tacoma News Tribune.

A. The best way to get rid of moss is to do the opposite of if you wanted it to grow. It prefers a firm acidic substrate (it doesn’t have roots but does have root like structures that help keep it in place) plenty of moisture as well as indirect sunlight (thus why it loves the north side of roofs better than southern side). So if you have poor drainage improve it by adding organic matter to the soil and working it in. cultivate the surface of the soil each month (this also helps control weeds) with a hoe or similar cultivating tool. Check the pH of the soil. Unless you are growing acid loving plants like rhodies and azaleas add lime to bring the pH up just below neutral (6.8 -6.9). And if possible prune the exising plants to allow more light to the soil surface. You can also help the process by using a natural moss control product like Moss and Algae Killer. – HG
