Common Uses for Bark, Mulch & Topsoil

From planting beds to playground surfaces — see where organic material does work that rock can't.

Mulching Planting Beds

Mulching Planting Beds

A 2" to 3" layer of bark or wood mulch over established beds suppresses weeds, slows evaporation, and feeds the soil as it breaks down. Refresh annually as it decomposes — that's the trade-off vs. inert rock mulch.

Building Raised Beds & Veggie Gardens

Building Raised Beds & Veggie Gardens

Premium topsoil filled to within an inch of the rim of a raised bed gives roots the depth and structure they need from day one. Mix with compost for vegetables; straight topsoil for trees and shrubs.

Tree & Shrub Planting

Tree & Shrub Planting

Backfill new tree and shrub holes with a mix of native soil and quality topsoil. Crown with 3" of bark mulch (kept off the trunk) to insulate roots and retain moisture during establishment.

Lawn Top-Dressing & Repair

Lawn Top-Dressing & Repair

A 1/4" top-dress of screened topsoil over a lawn evens out low spots, smooths the surface, and gives new seed something to root in. Overseed before top-dressing for the best take.

Children's Play Surfaces

Children's Play Surfaces

Engineered wood fiber (playground bark) at 9" depth gives ASTM-compliant fall protection under play structures. Refresh every couple of years as the fiber compresses underfoot.

Erosion Control & Slope Stabilization

Erosion Control & Slope Stabilization

Coarse bark or wood chip over a freshly graded slope holds soil in place until grass or ground cover establishes. Cheaper and friendlier-looking than the alternatives during the establishment year.

Bark, Mulch & Topsoil Buying Guide

Pick the right product for the job, calculate how much you need, and apply it correctly.

Bark, mulch, and topsoil are the organic counterparts to our rock products — they feed soil, retain moisture, suppress weeds, and provide the growing medium that plants actually need. Unlike rock mulch, organic material decomposes over time and needs refreshing, but in exchange it builds soil structure year over year.

Browse the full collection for what's currently in stock. The table below pairs each product with its best use and the tips cover the application details that make a difference.

What Gardeners Know

  • 3" is the right mulch depth. Less and weeds find daylight; more and water has trouble reaching the roots. Refresh annually as the layer breaks down to roughly half its original thickness.
  • Keep mulch off tree trunks. The volcano of mulch piled against a tree trunk holds moisture against the bark and invites rot and disease. Mulch flat in a ring with the trunk in the middle untouched.
  • Fresh mulch ties up nitrogen — temporarily. As bark decomposes, the microbes pull nitrogen from surrounding soil. In established beds it's negligible; in vegetable gardens, add a light nitrogen feed when you spread fresh wood chip.
  • Topsoil settles 15 to 25%. Order enough volume to fill the bed plus a quarter again. The first heavy watering will compact it to its working level.
  • For raised vegetable beds, mix topsoil with compost. A 70/30 topsoil-to-compost mix gives roots structure and food. Pure compost stays too wet; pure topsoil starves seedlings.
  • Schedule deliveries before rain. Bulk topsoil and mulch are easier to handle dry. Try to time delivery for a clear window so you can wheelbarrow it to where it needs to go without slogging through mud.

FAQ

Use the coverage calculator at the top of this page. Rule of thumb: 1 cubic yard covers about 100 sq ft at 3" depth. Bark mulch weighs about 0.5 to 0.7 tons per cubic yard; topsoil weighs about 1 ton per cubic yard.
Bark mulch is shredded outer bark from trees — finer, slower to decompose, prettier in beds. Wood chip is whole-wood chips from the rest of the tree — coarser, breaks down faster, good for slopes and paths. Engineered wood fiber is consistently shredded virgin wood meeting ASTM playground specs.
Plan to top-dress annually. A 3" layer typically settles and breaks down to about 1.5" after a year. Pull weeds, then add an inch or two of fresh on top — you don't need to remove the old layer.
Yes. Our premium topsoil is screened to remove rocks, roots, and clumps before it's bagged or supersacked. It comes out of the bag ready to spread without pre-cleaning.
Most projects yes — a wheelbarrow and a sturdy rake will get you through a typical residential bed in an afternoon. For larger volumes (over 5 cubic yards), supersack delivery and renting a small tracked loader is worth considering. Call (800) 215-7372 with your project for sizing help.
