Mulch and Topsoil questions, answered by experts

As a base, you should use a fertilizer with a 5-5-5 NPK ratio (5% nitrogen, 5% phosphorus, and 5% potassium). You may need a different ratio depending on what your soil is lacking, but a soil test can help determine the perfect amount.

The best size rock for your landscaping depends on the design, as different boulders serve different purposes. If you want to group boulders to create a natural-looking cluster, you’ll need a range of sizes. Otherwise, here are some suggestions:

  • Small boulders (smaller than 12 inches across): Best for landscape edging and fire pits 

  • Medium boulders (12–24 inches): Best for retaining walls and water features

  • Large boulders (more than 24 inches): Best as standalone landscaping features, steps, or walkways.

Of course, you can mix and match sizes to create a unique display.

The main benefit of topsoil is that it enriches the soil with nutrients that help your plants and garden grow at a healthy rate. Topsoil improves how well your soil drains water and gives it a more fertile texture, so that not only do you get better planting, but weeding is also much easier.

While you can put gravel directly on dirt, it won’t be very stable. It also won’t block out any weeds. Most experts recommend layering weed barrier and a layer of packed sand or other foundation material to prevent the gravel from sinking into the earth and being overtaken by weeds.

The least costly way to keep grass from growing is also the most labor-intensive: regular weeding. Pull out grass blades as you see them pop up through the soil in areas where they’re unwanted. Another cost-effective way to keep grass from growing is by spreading a thick layer of mulch on the area as this will suffocate the grass.
