Unlock the Benefits: Layering Gravel Under Mulch for a Thriving Garden

Gravel and mulch are two popular options for ground cover in gardens. Each serves a purpose: gravel is great for keeping weeds at bay, while mulch nourishes plants. Many gardeners find themselves debating whether to use one, the other, or even both. But is combining them really a good idea?

To get some insight, we spoke with Lara Hermanson, co-founder of Farmscape, a company that designs sustainable gardens in California. Hermanson emphasizes that sticking with mulch usually works best. "Adding gravel adds complexity without real benefits," she notes. Her team focuses on creating gardens that conserve water and enhance plant health, so they prefer using mulch alone.

Gravel does help prevent weeds but can also pose problems. Hermanson points out that using it under mulch often doesn’t give enough return on investment. In dry climates, she opts for water-retaining mulches instead. "Gravel can restrict growth and even cause root rot," she warns.

Instead of layering gravel, Hermanson suggests using eco-friendly mulches that improve drainage and weed control. There’s a variety of eco-friendly mulch options available for gardeners.

Alternatives to Consider

If you’re looking to spice up your garden without adding gravel, consider alternatives that can boost your yard’s health. Hermanson recommends implementing a rain garden, which absorbs excess water and supports native plants. Native plants are not just beautiful; they also require less care and help with drainage.

Another great option is raised garden beds. They offer better drainage and allow you to customize the soil mix for your plants. Hermanson believes they often make a bigger impact than layering gravel under mulch.

When facing persistent garden issues, Hermanson advises consulting with a professional landscaper. They can provide tailored solutions to meet your garden’s unique needs.

By choosing the right ground cover and garden strategies, you can create a thriving outdoor space that’s both beautiful and practical.
