Lawn Talk with Harold Enger – Podcast Transcription

Episode: Moss Control

Tim Kauffold: Welcome to Lawn Talk, I’m your host Tim Kauffold. Lawn Talk is a series of conversations with Spring-Green lawn care professionals. Joining me is Harold Enger. Harold has worked in the Green Industry for nearly 30 years and is a Certified Turfgrass and Ornamental Landscape professional.

Today on Lawn Talk we’re speaking with Harold about moss. Harold, what are some of the problems unique to the Pacific Northwest?

Harold Enger: Moss is one of the problems that is unique to the Pacific Northwest. Because of the weather conditions in the Pacific Northwest, which is about nine months of cool, mild rainy, overcast weather, it’s a great environmental condition for moss to grow. In fact, as they say, if it stands still for more than 10 minutes, moss will grow on it.  So often, lawns develop large, unsightly patches of moss.  It just doesn’t look good. So, it has to be sprayed with a product to control it. Iron sulfate is, usually, what is used to control it, or parasulfate, is sprayed on the lawn to kill off the moss.

Tim: But isn’t moss found throughout the U.S.?

Harold: Oh, sure, you can find it in many different places.  There are many different varieties of mosses, but the climate in the Pacific Northwest is especially conducive for the development of moss to great extent. Occasionally, we will see it in some lawns that are shady, or really wet, throughout the country, but the major concern is in the area of the Pacific Northwest. We have to include it as part of the program in order to keep it under control to provide our customers with good looking lawns.

Tim: You talked, just a moment ago, about having to put down a control for the moss that would kill it off. What happens then, after the moss dies?

Harold: The moss will, actually, turn black, so now you have big, black patches in your lawn, and you will need to rake out the larger patches—the smaller ones will decompose on their own.  You’ll need to rake to remove it out of the lawn, so that your grass can regrow and fill in those areas.

Tim: So, when I’ve cleaned the moss up, are there going to be some bare spots in the lawn, or is the grass pretty much there?

Harold: The grass will regrow into those areas. The grass is there.  It’s just being covered up by the moss. Once you get rid of the moss, the grass will grow. In certain severe situations, you may require some reseeding in the spring, but the lawn will recover on its own.

Tim: After I’ve had my Spring Green professional come out and take care of the moss for me, is it going to come back?

Harold: Well, unfortunately, the weather conditions are such that, yes, it will probably come back every year. Because of the extended cool, mild, wet weather, that folks in the Pacific Northwest have to endure every year, it’s going to be an annual event to spray the lawn for moss.

Tim: And, then should it be a part of the program for every homeowner out there.

Harold:  Yes, it should. There are a few lawns that may not have it, but for the most part, everybody has a problem with moss. It will need to be treated, or else, we will have a lawn that just doesn’t look good. In the summer time, believe it or not, it gets very, very dry in Washington, Oregon, and throughout the Pacific Northwest, and the moss will turn brown, which will not look very attractive in your lawn.
