Annually, peat moss accumulates at more than 70 times the rate it is harvested. Harvested bogs are returned to wetlands so the ecological balance of the area is maintained. Peat moss is a good value since it is compressed into bales. When opened, it expands to approximately twice the amount as packaged. Peat moss makes your compost more effective because peat and compost do two different things.
Peat moss restructures the soil, whereas compost provides nutrients.
By blending the two you can reduce compost s tendency to compact the soil, and thus allow more water, air and nutrients to reach plant roots. In addition, the peat moss and compost combination helps retain moisture in garden beds, allowing gardeners to water less frequently. Peat also extends the life of compost in soil by four to five times. Sphagnum peat moss can improve the composting process by speeding up the decomposition. Peat moss also retains water and reduces leaching of nutrients in the soil and minimizes odors in the compost pile.
