"Great service and honest people to work with! Charlie was able to give me a good estimate for repairing my concrete at my back yard. Although it was not a big project, Charlie agreed to do it and he sent to my house 2 guys that took out the old concrete and to do a new one with a nice design. The workers worked for 3 days in a row and they made sure to do their work without interfear us.  At the end they made sure to clean  and to ask our permission that everything is good.

Mulch and Topsoil FAQs, answered by experts

Yes, and in many cases, you should. Large gravel works best as a base layer because it improves drainage and keeps the surface stable. A top layer of smaller gravel fills in gaps and creates a smoother, more compacted surface. This combination is common in driveways and high-traffic areas where both stability and comfort matter.

In most cases, it’s better to remove rocks before adding mulch. Layering the two will restrict drainage and plant health, and can create an unpleasant texture underfoot.

The right depth depends on your intended use for the area. For instance, pea gravel for walkways and patios typically only needs to be about 2 to 3 inches deep. However, driveways and other areas with heavier loads may require 4 to 6 inches for better stability.

Wood from black walnut, magnolia, eucalyptus, red maple, and invasive species like tree of heaven are not recommended for mulching. These trees release allelochemicals that can suppress plant growth. Some homeowners, however, use wood from these trees for mulching if it is less potent due to age or concentration, or if the plants are not as sensitive to them.

Replace organic mulch every one to two years, depending on the variety. Wood chips and straw, for example, will last a couple of years, while grass clippings and pine needles need replacing every several months. Inorganic mulch—such as rock and rubber chips—can stay in place for up to four years, depending on erosion and general garden upkeep.
