Mulch and Topsoil questions, answered by experts

Yes, gravel comes in different sizes, from fine powder to pea-, coin-, and even golf ball-size. Pea gravel is about 3/8 inch, while crushed stone gravel is about 3/8 to 4 inches. Most companies use a numerical system to assign a size, with the smallest being #10 and the biggest being #1. 

Yes, rubber mulch allows water to seep through and reach the soil underneath. Rubber mulch is not as absorbent as organic mulch, which allows the soil underneath to stay moist and hydrated. Keep in mind that the permeability of rubber mulch can get clogged by landscape fabric and other additional materials.

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.

How tall your mulch should be around your tree depends on the type of mulch you use, but aim for 3 to 4 inches as a rule of thumb. You’ll want to avoid simply piling it up in hopes of offering additional benefits to your tree. Volcano mulching is the infamous term for piling way too much mulch against the stem of your tree. This could actually kill your tree or severely harm it, as your tree trunk needs space to breathe without too much moisture.

Measure the area needing coverage and consult with suppliers on average depth requirements for each material. Calculations often use cubic yards for accuracy and practicality.
