Yes, you can put topsoil over sand to encourage grass growth. The topsoil will help to improve water retention and promote grass roots’ development, making it a recommended step of the seeding process. Adding a layer of topsoil will provide additional nutrients to the sandy soil, helping the grass grow and remain healthy through many seasons.

The best type of rock for landscaping depends on your specific project and needs, as different rocks are suited for different applications. For covering large areas or creating an affordable driveway, consider gravel, but note that it can wash away in flowing water. For water features, river rocks are a good option. Flagstone and cobblestone are ideal for aesthetically pleasing patios and walkways. If you are building a stone wall, fieldstone or small boulders are up to the task. Large boulders and landscape rocks work well as statement pieces, to fill empty space, or to indicate boundaries, but be mindful that they can overwhelm smaller gardens. The best approach is to first define your landscaping project and then select the rock type that best fits that purpose.

The soil around your foundation should slope down and away from your home, not toward it. If the grading drops the farther you are from your home, you can enhance the slope by removing more soil. Mark off a few feet from your house and dig up some of this soil. Regrading around your fountain should encourage water to flow away from your home and not collect or “pond.”

Moss attaches to the ground but doesn’t have roots, so it can take four to six weeks for establishment to begin. It takes between 12 and 18 months for full coverage, and maximum thickness takes about two years. Keep your moss moist and debris-free to ensure it establishes itself well.
