If your lawn isn’t looking too healthy or weeds are taking over, it’s likely because your soil may be too acidic or compacted. To green up your lawn, soil amendments might be the way to go.
Soil amendments improve the physical nature of soil. They can help aerate the soil to reduce compaction, allow nutrients to move through more easily, and help water reach plant roots. The three primary types are clay soil, sandy soil, and loam, the ideal soil for gardening. Use a simple soil test kit to find out what kind of soil and where it falls in the range of acid to alkaline.
When you want to know how to amend soil, there are a lot of options out there to pick from depending on what your lawn needs. Always be sure to consult a tree arborist professional to ensure that you are protecting your property’s existing plant life.
For Lawns in Need of Water
- Vermiculite improves moisture retention and aeration.
- Sphagnum peat moss absorbs water, slowly releasing it for use by plant roots.
For Lawns in Need of Aeration
- Gypsum improves aeration of compacted soil, helping it drain more efficiently.
- Perlite improves aeration and drainage.
- Builder’s sand is coarse sand that can improve soil drainage.
For Lawns in Need of Nutrients
- Composts can be made at home or bought in different forms. For example, mushroom compost is a mixture of straw, peat moss and other organic components good for a home garden.
- Composted manure is an odorless farm byproduct. In addition to improving aeration and moisture retention, it enriches the soil.
For Lawns in Need of pH Balance
- Lime raises soil pH, reducing acidity.
- Sulfur lowers soil pH, increasing acidity.
