Secondly, what is a good substitute for peat moss? Here are some suitable peat moss alternatives you can use instead:

Compost.
Coconut coir.

How does peat moss help soil?

Peat moss helps the soil hold nutrients by increasing what is called the CEC or "cation exchange capacity." Peat moss has a low pH, so if you use much, lime should be added as well. Plants that do well in acidic soils, termed "ericaceous" such as blueberries and rhododendrons, benefit from peat moss.

Why is peat moss bad?

Peatlands store a third of the world's soil carbon, and their harvesting and use releases carbon dioxide, the major greenhouse gas driving climate change.
