Mulch is usually made of organic matter around the base of a plant, shrub, or tree. Mulch keeps water in the soil from getting too compacted when it rains. It also slows down the loss of earth and the flow of water.
Most of the time, landscapers and gardeners use natural, least-processed or semi-processed Mulch to keep weeds down, create moist soil, insulate plant roots, stop dirt from washing away, and improve the ground. If you lay Mulch over old Mulch, there’s no need to take these mulches away.
Also, Mulch helps keep the temperature of the soil stable and encourages the growth of microorganisms and worms in the soil. As Mulch breaks down over time, it lets nutrients and organic matter into the ground. Replace the Mulch as needed to keep a 2- to 4-inch-thick layer on top of the soil. Here, I will tell you and everything about how to lay Mulch over old Mulch.
