A good mulch layer helps retain moisture, suppress weeds, regulate soil temperature, and give your landscape a finished look. Organic mulches also slowly break down, improving soil structure and adding nutrients over time.

With several mulch options available, how do you know which one is best for your yard? Here’s a look at some common choices and how they perform in Midwestern landscapes.

Cedar Mulch

Cedar mulch is known for its natural oils, which help repel certain insects. This makes it especially attractive to use around foundations. Because it breaks down slowly, it tends to last longer than many other mulches and doesn’t need to be replaced as often. Its rich color will gradually fade to a silvery gray over time. 

Hardwood Mulch

Hardwood mulch is one of the most commonly used mulches in Michigan landscapes. It’s typically made from shredded hardwood bark and wood, giving beds a natural, dark appearance. When used in sufficient depth, it suppresses weeds effectively, holds moisture well during summer heat, and gradually improves the soil as it decomposes. You can also find dyed varieties such as black, brown, or red to complement the color palette of your home and plantings.

Cypress Mulch

Cypress mulch is valued for its durability and ability to resist decay. It also contains natural oils that help repel insects. Its fine texture holds moisture, making this an excellent choice to use in beds that tend to dry out quickly. It has a light color and beautifully complements many garden themes.

Pine Bark Mulch

Pine bark mulch slowly acidifies the soil as it breaks down, making it a popular choice for gardeners growing acid-loving plants such as rhododendrons, azaleas, blueberries, and hydrangeas. Its chunky texture can help stabilize soil on sloped terrain, and it allows water and air to move easily through the mulch layer, which helps promote a healthy root system.

Pine bark mulch decomposes quicker than cedar or hardwood mulch, so requires more frequent touch-ups, but tends to cost less.

How Much Mulch Should You Use?

For most landscape beds, aim for a 2 - 3 inch layer of mulch. This depth is enough to suppress weeds and hold moisture without smothering plant roots. 

Helpful tips:

• Keep mulch a few inches away from plant stems and tree trunks.

• Refresh mulch each spring as it naturally breaks down.

• Consider adding compost before mulching to improve soil fertility.

The Best Mulch for Your Landscape

There’s no single mulch that works for every garden. The best choice depends on your plants, your soil, and the look you want in your landscape. Consider things like color, aroma, durability, plant needs, and aesthetic appeal when selecting mulch for your landscape.

Many Michigan gardeners choose shredded hardwood mulch for general beds, pine bark for acid-loving plants, and cedar or cypress for long-lasting coverage.

Whichever mulch you choose, adding a fresh layer each season is one of the easiest ways to improve the health, beauty, and resilience of your garden.
