Get matched with top mulch and topsoil pros in Lynnwood, WA

Topsoil should go down first. If the topsoil is next to your house, make sure the grade slopes away from the house to keep water from pooling against your foundation and possibly leaking into your basement or crawl space. Don’t cover your decorative landscape mulch with topsoil as that defeats the purpose of laying down the mulch. If you’re trying to create a certain soil composition to improve plant growth, you’ll likely want compost mixed into the topsoil instead of mulch. Over time, any decorative wood mulch will simply decompose under the topsoil.

Permits depend on local regulations concerning street use and public spaces. Check requirements with community authorities to avoid fines or logistical issues.

The depth of your decomposed granite depends on its intended use, but around 3 to 4 inches is the most common depth. Driveways that need to support a lot of weight should be at a depth of no less than 6 inches. Walkways that won’t see a lot of weight but lots of foot traffic should be built at a depth of 3 to 4 inches, and patios should also be between 3 and 4 inches deep.

No, gravel and crushed rock are different. Crushed rock is made in a quarry and has sharp, jagged edges. It’s most commonly used for building and construction.

Gravel naturally occurs in river beds or lakes and features smooth edges, making it a better choice for landscaping or other decorative areas. Like crushed stone, gravel can also be found in quarries, but it’s typically due to rock-on-rock erosion rather than machinery.
