Peat moss has been used as a soil amendment for so long because it has a lot to offer.
For clay and heavy soils that get compact easily, it softens the soil structure and improves the drainage.
For sandy soil, peat moss helps retain moisture and nutrients for plant roots.
It is often applied with the ratio 2:1. 2 parts of soil per 1 part of peat moss.
If you intend to use peat moss as a soil amendment, you should know that it changes the pH level of the soil. Keep that in mind and, measure and watch out if the pH level drifts too much.
Peat moss is also a good growing medium for the soilless culture. However, people do not use it alone, but often in conjunction with other growing media like perlite, vermiculite.
If you wish to use peat moss for pure hydroponic growing, you should know some facts about why it is not appropriate. Because peat moss is an organic matter, if provided with plenty of oxygen and nitrogen, it will start to decompose. When that happens, the material can compress around plant roots and will choke off your plants.
So better to mix with other materials.
Peat moss is often blended with growing media such as perlite, vermiculite to balance the moisture and aeration.
One of the most useful roles of peat moss is in seed starting because this material is very sterile. Its antiseptic qualities naturally prevent bacteria and fungi from the seeds. It also gives excellent drainage, good aeration, fine texture, and low fertile, making it very ideal for germination.
For this purpose, you can use the peat moss alone or in mixture with some soils. Or remove the hassle by getting the peat pellets sold on the market.
Many people also prefer the soilless mix of peat moss, perlite, coconut coir, vermiculite and others in different amounts. This prevents the diseases, fungus, bacteria, weed seeds, and other bad things commonly found in the soils,
Growing acid-loving plants
Because of its low pH, peat moss is very suitable for vegetables and fruits that require an acidic environment. These include blueberries, pieris, heathers, azaleas, camellias, tomatoes, and so on
