Everything You Need to Know About Mulch Installation

When it comes to creating a healthy, attractive, and low-maintenance landscape, mulch is one of the best investments you can make. It’s not just about making flower beds look polished—mulch plays a vital role in soil health, moisture retention, and weed prevention.

So let’s dive into everything you need to know about mulch installation—and why early spring in Des Moines is the perfect time to get started.

Mulch installation is beneficial any time of year, but early spring in Central Iowa is hands-down the best season to get it done. Here’s why:

1. Weed Prevention Starts Early
Spring is when weeds begin to sprout. Applying mulch before they germinate gives you a major head start in weed suppression. A thick layer of mulch blocks sunlight, making it much harder for weeds to grow.

2. Moisture Retention Before Summer Heat
Mulch helps the soil retain moisture. Installing it early in the spring gives your plants a strong start by locking in spring rains and protecting the soil from drying out in the summer sun. This is especially valuable during Iowa’s hot summers.

3.Soil Temperature Regulation
In early spring, nights can still get cold. Mulch helps regulate soil temperature, protecting tender roots and newly planted flowers and shrubs from sudden temperature swings.

4. Boosts Curb Appeal at the Start of the Season
A fresh layer of mulch immediately improves the appearance of your landscape. By installing it in spring, you enjoy that crisp, clean look all season long. This is a great way for Des Moines homeowners to boost their property’s visual appeal early in the year.

Proper mulch depth is essential. Too little and it won’t do the job—too much and you could harm your plants.

Avoid going over 4 inches, as this can suffocate plant roots, prevent water from reaching the soil, and create a breeding ground for pests.

Mulch is typically sold by the cubic yard. One cubic yard covers:

Mulch is typically sold by the cubic yard. One cubic yard covers:

      1. Measure the length and width of your beds in feet.
      2. Multiply to get square footage.
      3. Divide by the coverage above depending on your desired depth.

Example: A 10×20 bed = 200 sq ft
At 3 inches deep: 200 ÷ 100 = 2 cubic yards of mulch

If that sounds like a lot of math, don’t worry we’ll calculate the exact amount you need when you schedule a service with Excel Lawns & Landscape.

The cost of mulch depends on the type (hardwood, dyed, cedar, etc.) and whether you’re buying it bagged or in bulk. In Des Moines, Iowa, average mulch prices are:

If you’re hiring a professional (like Excel Lawns & Landscape), you can expect pricing to include:

Professional mulch installation typically ranges from $60 to $100+ per cubic yard, depending on terrain, type of mulch, and total volume.

While you could do it yourself, many of our customers find that hiring a professional saves time, effort, and ensures a cleaner, longer-lasting result.

If you’re a DIYer, here’s a step-by-step guide to installing mulch properly:

Remove old mulch (if deteriorated), weeds, and debris. A clean surface ensures new mulch does its job effectively.

Create a physical barrier between your beds and lawn using an edging tool. This gives a tidy look and helps keep mulch in place.

Some people use landscape fabric, but we recommend caution. Fabric can prevent soil from breathing and make it hard to add new plants later. In most cases, a thick layer of mulch alone will suppress weeds just fine.

Use a rake or gloved hands to distribute mulch to a depth of 2–4 inches. Make sure it’s level and not mounded against stems or trunks.

Give the mulch a gentle soak to help it settle in place and reduce blowing or movement.

Of course, the easiest way to get this done is to call Excel Lawns & Landscape. We handle everything from prep to installation, so you can sit back and enjoy your beautiful landscape from the deck.
