Ten Reasons Why You Really Need Rocks

Here are ten reasons why your landscape—especially if it includes succulents—really needs rocks, large and small.

Remember when crushed-rock front yards were a ’60s retirement-community cliche? Not any longer! Nowadays smart designers cover bare soil with rocks to create gardens that are as sophisticated and good-looking as they are practical.

In my video, Van Liew Garden Redo, San Diego landscape designer Steve McDearmon explains how he installs succulents amid swaths of warm-toned Mojave Gold gravel, Hickory Creek rubble rock, and Honey Quartz boulders (all from Southwest Boulder and Stone). Though subtle, the rocks are as important as the plants.

Ten Reasons for Rocks: They…

— need no maintenance and look the same forever.

— contrast texturally with walls, pavement, and plants.

— add color and cohesion to a landscape.

— moderate soil temperature, keeping it warmer in winter and cooler in summer.

— hold moisture in the soil and inhibit evaporation.

— prevent erosion by diffusing the impact of rain.

— give a garden a finished look. (Doubtless you already know that topdressing is important for containers. The same is true of gardens.)

— are visually intriguing, especially when several sizes combine.

— lend design interest and emphasize focal points when used to create flowing lines in the landscape.

— prevent weeds from germinating by shading the soil. And any that do pop up are easier to pull.

    Thanks for going over some benefits of using rocks in your landscape. I actually didn’t know that they can moderate soil temperature, like in the winter and whatnot. I’m kind of interested to learn if there are specific types of rocks that can do this or if some are better at it than others.

      The larger the rock (boulder) the better at moderating soil temperature. Rocks absorb heat from the sun during the day and release it gradually at night. The denser the rock, i.e. granite vs lava, the better, I would think, but I’m no expert.

        I suspect that this may be helpful in colder climates?

    I have started collecting rocks from our property to use in my very new succulent garden, and I like the idea mentioned here to also use rocks to create a flow and focal interest. I could buy some contrasting ones for that, so thanks for pointing that out.

    My wife and I are wanting to landscape our yard later this year, so thanks for sharing this. I like your point about how landscape rocks can add color and cohesion to a landscape. We feel like the yard is boring as it is, so getting some colorful rocks might help break it up a bit.
