When most people think of mulch, they picture wood chips.

But here in New Mexico, one of our most unique mulches begins somewhere entirely different... A pecan orchard.

A New Mexico Tradition

Did you know New Mexico is one of the nation's leading pecan-producing states?

Drive through southern New Mexico and you'll pass thousands of acres of beautiful pecan orchards stretching across the Mesilla Valley and surrounding communities. Every autumn, those trees produce millions of pounds of pecans destined for grocery stores, bakeries, candy makers, and kitchens across the country.

After the nuts are harvested and shelled, the shells remain as a natural by-product of the industry. Rather than going to waste, they've long been used throughout the South and Southwest as an attractive, functional landscape mulch.

At Soilutions, we're proud to offer this time-tested mulch, giving a local agricultural by-product a second life while creating beautiful, water-wise landscapes across New Mexico.

Naturally Beautiful

Fresh pecan shells have a warm brick-red color that instantly adds richness to the landscape.

Over time, exposure to sunlight and the elements naturally deepens the shells into a rich chocolate brown. Unlike dyed mulches, there are no artificial colorants involved—the changing color is simply part of the shells' natural aging process.

Pecan Shell Mulch is especially popular with rosarians. The warm red tones create a striking contrast against the deep green foliage of rose bushes, making blooms stand out even more dramatically throughout the growing season.

Built to Last

Of all the organic mulches we carry, Pecan Shell Mulch is our most durable.

The hard shells break down much more slowly than wood-based mulches, meaning they stay attractive for years while still gradually contributing organic matter back into the soil.

If you're looking for an organic mulch that doesn't need to be refreshed as often, pecan shells are an excellent choice.

A Beautiful Alternative to Gravel

Gravel is a popular landscape material throughout the Southwest, but it comes with a downside.

Rock absorbs and stores heat all day long, then slowly releases that heat well into the evening. Around plants, that extra heat can increase water loss and place additional stress on roots during New Mexico's hottest months.

Pecan Shell Mulch offers a different approach.

A layer of pecan shells helps:

💧 Reduce moisture evaporation

🌡️ Moderate soil temperatures

🌱 Protect plant roots from extreme temperature swings

Unlike gravel, pecan shells gradually break down over time, adding organic matter back into the soil while providing years of beautiful ground cover.

Great for Pathways

One of the things customers love most about Pecan Shell Mulch is something you can't appreciate in a photograph. It crunches under your feet.

That satisfying sound—and its long-lasting durability—make it a favorite for:

• Garden pathways

• Courtyards

• Xeriscape landscapes

• Around raised beds

• Decorative planting areas

Naturally Discourages Some Pests

Another unique benefit of pecan shells is their naturally angular texture.

Unlike softer mulches, the shells create a surface that many crawling pests prefer to avoid, making them a popular choice around ornamental beds and rose gardens.

While no mulch completely prevents pests, many gardeners appreciate the shells' firm, textured surface compared to softer organic mulches.

Frequently Asked Question:

Will Pecan Shell Mulch Attract Rodents?

This is one of the most common questions we receive, and the honest answer is yes—but only temporarily.

During the shelling process, it's nearly impossible to remove every tiny piece of pecan meat from the shells. Because of those small remnants, you may notice a few birds, squirrels, or other small wildlife investigating freshly installed mulch during the first several days.

The good news is they're simply cleaning up those remaining bits of pecan. Once the tiny food particles are gone—typically within about a week—the shells themselves are no longer a food source, and the activity quickly subsides.

For most homeowners, it's a short-lived occurrence that's simply part of using a natural agricultural product.

A Natural Choice

Like all of our mulches, Pecan Shell Mulch is made from a by-product that would otherwise have little value.

At Soilutions, we believe the best mulch isn't manufactured—it's reclaimed from nature and given a second purpose.

Whether it's arbor chips from local tree work, pecan shells from New Mexico orchards, or compost created from recycled food scraps and green waste, we're committed to finding beneficial uses for natural materials that might otherwise be discarded.

That's what organics recycling is all about!

🌰 The Bottom Line

Pecan Shell Mulch is one of New Mexico's most distinctive landscape materials. Sourced from the state's thriving pecan industry, it gives an agricultural by-product a valuable second life while creating beautiful, functional landscapes.

Its rich natural color, exceptional durability, water-saving benefits, and unique texture make it an excellent choice for pathways, rose gardens, ornamental beds, and water-wise landscapes. If you're looking for an organic alternative to gravel that lasts for years while supporting healthier soil, Pecan Shell Mulch is hard to beat.

Soilutions offers Pecan Mulch in bulk and in 2 cubic foot bags available at most local plant nurseries.
