Why Should You Care About Peat Moss?

That’s a tricky question.

The answer has to do with what happens when it’s harvested.

Holds Earth’s Carbon

Peat forms very slowly in cool wetlands as sphagnum moss decays.

“It’s almost impossible to get it back to the way it was,” says Chalker-Scott.

“I compare it to cutting down old-growth forests.

Sure, you’re free to plant new trees, but it will take a long time.”

What Are the Alternatives to Peat Moss?

Chalker-Scott recommends avoiding it altogether.

“It doesn’t do anything that’s crucial for plant life,” she says.

“Otherwise, there wouldn’t be any plants except right around peat bogs.”

Search Plant-Based Materials

Luckily, plenty of other options exist.

it’s possible for you to also try making your own mix from these alternatives.

None of these substitute materials work quite as well as peat moss.

With the alternatives, you may need to pay more attention when watering.
