Mulch is generally the better choice for garden beds with plants because it improves soil health, retains moisture, and regulates temperature, while decorative stone works best in low-plant areas where permanence and minimal maintenance are priorities. This is one of the most common questions we hear from homeowners in the Powassan and North Bay area, and the answer depends on what you want the ground cover to do and where you are using it. Both mulch and stone have legitimate roles in landscape design, but using the wrong material in the wrong location creates ongoing problems. Martin Services installs both mulch and decorative stone ground covers and helps clients choose the right option for each area of their property.
When Mulch Is the Better Choice
Organic mulch — cedar, hardwood, or bark — is the superior choice for garden beds that contain trees, shrubs, perennials, or annuals. As mulch decomposes over one to three seasons, it adds organic matter to the soil, improving structure, water retention, and nutrient availability. Mulch maintains more consistent soil moisture levels by reducing evaporation, which means less watering during dry summer stretches. It also insulates plant roots from temperature extremes — keeping roots cooler in summer and warmer in fall, which extends the growing season slightly and protects against early freeze damage. In Northern Ontario, where freeze-thaw cycles can heave shallow-rooted plants out of the ground, mulch provides critical temperature buffering that stone cannot match.
When Stone Makes More Sense
Decorative stone is the better choice in areas without plants or with very few, widely spaced plants. Around foundations, in drainage channels, between stepping stones, in rock garden features, and along driveways or property borders, stone provides a clean, permanent ground cover that never needs replacement. Stone does not decompose, does not blow away, and does not attract insects. However, stone has significant drawbacks in planted garden beds — it absorbs and radiates heat in summer, which can stress plants and dry out soil. Stone does not improve soil health or add nutrients as it ages. Weeds that grow through stone mulch are harder to remove because their roots grow around and between the stones. And in fall, cleaning leaves out of stone beds is more difficult than raking them off a mulch surface. With 35 years of experience, Martin Services helps you use each material where it performs best for a landscape that looks great and functions properly.
