Coco Vs. Peat Moss

Both peat moss and coco are commonly used as soil amendments.

If you're looking to mix your own potting soil, the choices can at first seem confusing. Peat moss? Coco? What's the difference, and why would your soil need either? But don't worry, peat moss and coco fill much the same function, and for many gardeners, the choice comes down to personal preference.

What Is Coco?

Coconut husks are the source of coco, also called coco peat.

Made from the shredded husk of the coconut, coco (also called coco coir, coconut coir or coco peat) is a light-brown fiber that absorbs many times its weight in water.

Peat Moss

Peat moss, which is also commonly known as sphagnum, is farmed from peat bogs. After harvesting, the peat moss is decomposed, compressed and packaged into bricks.

Why Use Either?

Coco and peat moss are both used as soil amendments. When mixed into potting soil, they keep the soil from compacting---which can prevent root growth---and help the soil hold on to water.

Peat Moss: Traditional Choice

Peat moss has been used as a soil amendment for a much longer time than coco and is more widely available. Most commercial potting soils contain some amount of peat moss.

Rise of Coco

Coco has risen in popularity in recent years, as concerns about the environmental hazards of peat bog farming have led gardeners to look for a greener alternative.
