Mulch refers to any material applied over the soil surface, from bark and wood chips to plastic or paper. Unlike soil amendments, which must be mixed into the soil, mulches stay on top and serve a different set of functions\u2014protecting soil, improving plant health, and enhancing visual appeal.<\/p>

Mulch is a critical part of landscape care. Choosing the right mulch depends on the effect you want\u2014whether it\u2019s moisture retention, weed control, or simply a cleaner, more polished look. Here\u2019s what to consider:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Let\u2019s be honest\u2014mulch makes a garden look finished. Like framing a picture, it ties everything together. While looks often drive the choice, remember: appearance is just one piece. Pick two or three mulch types you like visually, then compare their practical benefits before deciding.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Blocking weeds is a top reason to mulch. Some mulches are more effective than others, especially those that create a strong barrier\u2014like black plastic. While not pretty or eco-friendly, it\u2019s widely used on farms because it works.<\/p>

More sustainable options include thick layers of coarse bark or wood chips. Our mulches are made from clean urban wood or forestry byproducts\u2014attractive, biodegradable, and environmentally sound. While not as aggressive as plastic, they suppress weeds well and support soil health.<\/p>

Still, some weeds can break through, like oxalis or rhizomatous grasses. Oxalis, in particular, stores energy in bulbs that let it push up through most mulches. The best time to pull them is during mid-winter when bulb energy has been depleted during the formation of new shoots.<\/p>

Although mulch helps suppress weeds, expect to do some weeding. Weeds are tenacious, spreading by seed, roots, rhizomes, and more. Mulch will reduce their numbers but not eliminate them. Typically, weedy plants that reproduce from roots, rhizomes, and bulbs are the most difficult to control and often require removal by digging them out.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Mulch helps soil retain moisture, especially in dry, hot climates. Bare soil heats up fast, dries out quickly, and loses water to wind and sun. A mulch layer insulates the soil, keeping temperatures lower and reducing evaporation. It also provides a vapor barrier that holds moisture in the soil.<\/p>

Combined with drip irrigation, mulch can dramatically reduce water use. Even with overhead watering, mulch reduces the need to water as often. However, mulch can absorb water from overhead watering and release it back into the atmosphere before it enters the soil, essentially wasting this water. Some mulches absorb more water than others.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Good soil is crumbly, not compacted. It\u2019s made of small and large aggregates that allow air and water to move freely through it. When soil is left bare, sun, rain, and foot traffic break the aggregates down, leading to crusted, compacted soil. In severe cases, this can lead to water puddling during rains or irrigation. A sigh that water is not moving into the soil. The reduction of air movement into the soil is less visible but also damaging to root systems. Plants do not grow well under these conditions. It is not uncommon to see stunted shrubs showing little growth year after year in exposed soil areas. Even weed growth can be inhibited.<\/p>

Mulch prevents these problems by protecting the soil\u2019s surface, preserving the crumb structure, and allowing the essential movement of air and water through the soil. It is a role of mulching that is often overlooked, although it is one of its most important functions.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
