I like moss. Actually, I love it. I love the delicate textures and vibrant colors. We incorporate it into our landscape designs and have experimented with cultivating it. Did you know you can buy it? Yep- this Washington nursery carries it.

However, even a moss fan like me has to acknowledge that it isn't desirable everywhere in your landscape. If you have a moss filled lawn you probably don't like it.

What can be done about moss in your Portland turf?

How To Get Rid Of Moss In Your Lawn

The first step is to get rid of your moss. This can be done manually or with iron, often a combination of both is best. You can use a stiff rake and just rake it out. If you have just a small patch in your lawn this may be the best choice. Lawns full of moss can be very labor intensive to clear this way. Iron kills moss quickly. If you use the liquid iron available at your local hardware store it will be black within an hour of application. Iron pellets or powder takes a little longer, but is more practical for large lawns.

Once the moss is dead you have two choices. It will eventually break down and disappear. But if you don't want to wait you can rake it after it's dead. Now that your lawn is free of moss, how do you keep it that way?

How To Prevent Moss From Appearing In Your Lawn

Our landscapes here in Portland tend to be shady and wet- a perfect place for moss. Even in dense shade, however, most moss can be prevented. How? Application of lime. Moss prefers acidic soil, we are also prone to acidic soil here. Lime increases Ph and makes the soil less hospitable to moss. Lime will not get rid of moss that you already have but it can greatly reduce the amount that appears every winter.

Conventional wisdom is that you should have a soil test done before applying lime. This is not a bad idea, but not absolutely necessary here in Portland. Because we are so prone to acidic soil it is pretty safe to assume that moss means low Ph.
