Landscape rocks should be installed about 2 to 3 inches thick to reap their intended benefits. At this thickness, your rock ground cover can effectively retain soil moisture, suppress weed growth, and regulate soil temperature. There should also be an inch gap around the base of your plants to prevent the rocks from trapping too much moisture underneath and smothering the plants. If your rocks start to look worn down, you can refresh them with a new layer to keep your landscape in Texas neat and manicured.

A layer of landscape rock should be about 2 to 3 inches thick.

When using rocks for your landscape's ground cover material, the layer should be around 2 to 3 inches thick. This thickness allows you to maximize the benefits of the landscape rocks without causing any issues to your plants. Here are a few reasons why this thickness is ideal:

  • Soil Moisture Retention: Landscape rocks help retain moisture in the soil by reducing water loss from evaporation. Covering the soil with a 2- to 3-inch layer of rocks creates a barrier that blocks sunlight and slows evaporation. As a result, your plants' roots stay moist, helping them survive even in warm weather.
  • Weed Suppression: Rocks keep weeds from growing in your landscape beds by preventing weed seeds from accessing the sunlight they need to germinate and grow. Without weeds, your landscape will stay healthy and well-manicured.
  • Soil Temperature Regulation: A 2- to 3-inch layer of rocks insulates and helps maintain stable soil temperatures. This keeps the soil warm enough in winter and cool enough in summer. Regulating soil temperature protects the plant roots from harsh weather conditions!

Leave about an inch between the rocks and the base of your plants to avoid smothering them.

In addition to keeping the landscape rock layer 2 to 3 inches thick, make sure you leave enough space around your plants. Ideally, there should be an inch of space between the rocks and the base of your plants to avoid smothering them. When you pile up the rocks right against the stem or trunk of your plants, it can trap moisture underneath and create an environment where diseases could foster. It can also inhibit proper air circulation and suffocate the roots, which can lead to root rot that can affect the health of your plants. Avoid these issues by ensuring there is enough space for your plants to breathe!

How often should you refresh your rocks?

One of the advantages of using rocks as landscape ground cover is that they don't decompose. This means they are more long-lasting! However, they can start to look worn down over time because of factors like weathering and exposure to the elements. You can refresh your landscape rocks when they begin to look dull or worn out. This will give your landscape beds a fresher and neater look while also ensuring your plants can maximize the intended benefits of the ground cover.

Maintain your landscape rocks by hosing them down with water occasionally to remove dust and dirt.
