The installation of sod paired with a new mulch bed really revived this yard.
Deciding whether or not you need to bring in nutrient rich top soil can be a bit tricky. Sod experts at Red Hen claim that adding topsoil is not essential for sod but it will provide some benefits. What topsoil does is increases a soil’s water and nutrient holding capacity. If you add it, the intervals between watering and fertilizing will be longer. When adding topsoil, 2 inches will provide good benefits only if you mix it into the existing soil. If you cannot have the topsoil mixed into the existing soil, then do not apply it! A thin layer of topsoil prevents grass plants from rooting deeply. This is important to note because you do not want weak roots. Weak roots will prevent your turf from growing strong and remaining healthy.
