The soil underneath of your Zoysia lawn supplies your grass with nutrients and water as it grows. While Zoysia grows well in a variety of soils, it’s important to know the type of soil you’re working with.
Sandy soil is made of larger rock particles that fit loosely together. While this type of soil does not lend itself to remaining moist, its roomy airspaces allow Zoysia’s roots to penetrate and provide quicker root development. Prior to planting though, this type of soil might require some alteration in the form of manure or compost if it is more sand than soil.
Silt-based soils are made of medium-sized particles that can often only be seen with the aide of a microscope. These types of soils shed water quickly, but feel slick to the touch when they are wet. They tend to be rich in nutrients and a great growing environment.
Clay-like soils are made of tiny particles that stick tightly together. These soils hold water and nutrients well, but they are also susceptible to “winter heaving” which can be harmful to perennial plants. It is best to mix your clay soil well with an organic matter to reduce its compaction, making it easier for roots to grow.
Organic matter is made of organic materials like compost, decomposed manure and shredded leaves. When applied to sandy or clay-like soils, it helps to maintain ideal moisture levels and creates airspace to help roots grow as needed. By adding organic matter in moderation, you alter your existing soil and give your Zoysia lawn the best chance to grow and thrive.
Remember, a big part of keeping your lawn healthy and beautiful is knowing what’s underneath it. Knowing what type of soil you have prior to planting your Zoysia lawn will help it to grow and thrive for years to come.
