A friend lives in a low-lying area near the Chesapeake Bay. She tells me that you just can't find any rocks, stones, or even pebbles in her soil, and it isn't because she's gardened carefully over the years. They just aren't there.While I envy the lack of pesky stones in her garden soil, I feel sorry for her, in a way. Stones can really add character to a yard and even save you money in the long run while being kind to Mother Earth. For example, stonework can help with watering costs. The more stones you have as a conscious part of your yard and garden, the less you have to water it. It isn't just the desert these days that has problems with getting enough water; areas that historically suffered drought rarely are now finding that they need to curtail their water use. This gorgeous yard has used stones and water-sipping perennials to wonderful effect. Note the whimsical roadrunner. Way to make lemonade out of lemons!
It's true that stone isn't a renewable resource in that you can't make or easily catch more of it, as you can with mulch and sunpower. However, it's very kind to the planet to use it as part of your landscaping. It requires little to no upkeep you might have to weed around it, but that's it. No harmful chemicals are necessary to keep it looking beautiful. No extra water is used for it unless you put in a pond, but that's another matter. It doesn't emit anything harmful, and it's completely safe to be around. In addition, gardening with stone can create beauty, and the world can always use more of that.
