Should You Spread Peat Moss On Your Lawn?

Growing peat moss at the garden

Peat moss helps your grass seed germinate by retaining moisture and providing cover while the seeds are in their most vulnerable state. Although it helps grass grow, it also comes with some caveats.

Peat moss reduces soil quality in the long term by turning soil more acidic as it leeches nutrients. It also contributes little to the earth when it degrades.

Another negative quality of peat moss is that it is environmentally unsustainable. Peat moss is harvested by draining naturally occurring swamps, which causes irreparable damage to the ecosystem.

Also, it takes a very long time for peat moss to grow back, so the damage is detrimental.

Are There Alternatives To Peat Moss?

There are some excellent alternatives to peat moss that can work just as well, if not better. Compost is a perfect substitute for peat moss because it's extremely environmentally friendly and contributes nutrients to your soil.

Plus, it provides extra moisture retention and cover for grass seeds. Coconut coir, pine needles, and leaf mold are also wonderful alternatives that are safer for the environment.

How Do You Know When To Water Peat Moss?

Check your lawn by inserting your finger into the soil about 2-inches deep to feel how moist the moss is. If the moss feels fairly dry, it's time to water. But if it's still damp, you can wait a couple more days and check again.

Make sure you check a sunny portion of the lawn since these areas dry out the quickest.
