Peat Moss Benefits and How to Use Peat Moss in Your Landscaping

The term peat moss often conjures images of dense, wet bogs in Ireland, Scotland, and Canada. You might be surprised, however, to learn that peat moss is a common soil amendment and is often used in both hydroponics and everyday landscaping in the United States. Maybe your landscaper has recommended adding peat moss to your garden or lawn and you’re curious about peat moss benefits.

In this article, we’ll dive into the bogs to help you learn the main uses for peat moss and how you can use peat moss for your lawn.

What Is Peat Moss?

What is peat moss good for? Before we can answer that question, it helps to understand what the substance actually is — or isn’t. Peat moss isn’t a specific type of moss or a plant of any kind. Instead, it is a partially decomposed accumulation of plant material that forms in peat bogs or peatlands over thousands of years.

Peat moss is typically composed of mosses, sedges, shrubs, and other vegetation that grows in wetland areas. It’s mostly made up of sphagnum moss and may even sometimes be incorrectly referred to as sphagnum moss. The two terms are related but different. Sphagnum is a specific, living moss. Peat moss is not alive.

While peat moss can evoke romantic visions of Irish and Scottish bogs, most peat moss in the United States is harvested in the peatlands of Canada.

Uses for Peat Moss in Landscaping

Thick blocks of decomposed organic material can do wonders for weak soil, hungry seedlings, and new lawns alike.

Soil Amendment

One of the most popular uses for peat moss is as a soil amendment, meaning it can improve the health of the soil. In particular, the spongy texture of peat moss can loosen dense soils, improve aeration, and help soil retain more moisture.

Seed Starting

Peat moss is sterile, lightweight, and great at holding onto moisture, which makes it an excellent ingredient in seed-starting mixes. If you’re looking to start a new garden of flowers, herbs, or vegetables, a peat moss mix could set up your seedlings for success.

Lawn Establishment

Much like new gardens, new lawns need a little help getting established. The same features that make peat moss so useful in boosting garden plants also make it a great medium for aiding the germination of grass seeds.

Mulching

Peat moss can also serve as a good mulch in garden beds and around trees. Its ability to suppress weeds, moderate soil temperatures, and retain moisture can keep plants strong and healthy.

Peat Moss Benefits

Should you consider using peat moss for your lawn? Here are some of the primary benefits of mixing a little peat into your soil.

It Retains Water

The spongy, fibrous texture of peat moss makes it superb at absorbing and retaining water. This ability can help keep the soil moist and plant roots hydrated. Using peat moss may allow you to lower the amount you need to water your garden or lawn and may be useful during periods of drought.

Provides Acidity

Peat moss is highly acidic, with a pH around 3.0 – 4.0. Certain plants love acidity, including the following:

• Azaleas
• Camellias
• Hydrangeas
• Irises
• Dogwood trees

Mixing some peat moss into the soil can help these plants thrive. It can also be beneficial to add peat moss to soil that is too alkaline and needs a better pH balance.

Complete Sterility

Peat moss is fully sterilized before it is packaged and sold, meaning you won’t have to worry about introducing bacteria, fungi, or weeds into your lawn or garden. The sterility of peat moss also ensures that it is a clean growing medium for vulnerable seedlings.

Holds Nutrients

The same characteristics that allow peat moss to absorb water also help it hold on to the nutrients you add to your soil. Peat moss does not provide nutrients to your soil and plants, but when you fertilize your lawn or garden, the peat moss in the soil can help ensure the fertilizer doesn’t quickly wash away.

Lightweight

Hauling around bags of soil can be physically challenging, especially if you are planning a big gardening or lawn project. Peat moss is very light, making it easy to work with whether you want to amend your soil or make potting mixes.

Is Peat Moss Right for You?

In this article, we’ve reviewed the uses of peat moss and highlighted several peat moss benefits. Does that mean we recommend peat moss for everyone? Not necessarily. Peat moss is just one option among many soil amendments that can help support a healthy, thriving lawn and garden. It is a non-renewable resource and is often more expensive than other alternatives, like compost, coconut coir, and pine bark.
