Has Moss Taken a Lichen to Your Lawn? Get It Under Control with Help from Spring-Green


Moss may have an epiphytic relationship with the trees and plants that grow in the forest, but when it comes to your lawn, this green, carpet-like epiphyte is anything but welcome.

Moss takes root in the bare patches of your lawn during the dark and rainy Pacific Northwest days.

In the Pacific Northwest, damp and shady conditions create the perfect breeding grounds for moss to grow — where grass is thin or not present. Your best defense against moss growth is a full, healthy lawn. But when moss does find its way into unwanted areas of your yard, Mike Bell, owner of Spring-Green Lawn Care, and his experienced team of lawn care professionals can help.

Mike says moss is most often the result of a lawn that is not full and healthy. “If you have a lawn that is well taken care of through fertilization, weed control and aeration, you crowd out the opportunity for moss to take over,” he explains. A lawn that is lacking in good health, however, helps create the perfect environment for moss to take hold. And after a particularly dry summer, your lawn may be suffering. With the darker, rainier days of winter ahead, moss is most likely moving in right under your nose.

“A lot of lawns died this summer because of the drought,” Mike says. “Those are areas where moss is an opportunist; it will be one of the first things to come in.” Because the moss grows in before the grass has a chance to, Mike says it crowds out the opportunity for your lawn to recover on its own. “If there’s bare ground or sparse turf, the moss will try to grow in those areas,” Mike explains.

Concerned about moss growth in other parts of your yard? Mike Bell says moss growth on bark and branches won’t harm the health of your trees.

But to combat this, Mike says removing the moss alone is not enough — you need to aerate and over seed the affected areas in order to stimulate new lawn growth, and there’s no better time than in the spring once the soil begins to warm up.

Once unwanted moss has been killed by Spring-Green and raked from your lawn, that’s where Mike and his experienced team of lawn care professionals can aerate and over seed the areas where the moss has been removed, ensuring that your lawn has its best chance for recovery.

Once your lawn is healthy again, Mike says preventative care is key to stopping future moss growth, and there are many factors to consider, including poor drainage, too much shade, low soil fertility, compact soil, and too much acidity.

Mike says acidic soil levels are common in this region. But a simple application of lime can help balance the pH of your soil. While the lime itself does not prevent the growth of moss, the lime application works together with fertilizers, creating an optimal environment for healthy grass growth. “Lime breaks down with the fertilizer we put down, allowing the grass roots to take better hold,” Mike explains. If you want to take preventative measures against future moss growth — or just want to ensure the health of your lawn — an annual lime application is a great way to do this.

With so many dark, damp months, Mike says moss has found a happy home in the Pacific Northwest. But he says not all moss growth is damaging. “A lot of people get worried about moss growing on the sides of their trees or branches,” Mike explains, “but it doesn’t harm the tree or shrub, it is an epiphyte drawing in sustenance from the air and water.”
