Phew, X was a hard letter to find something to write about. But in searching around I came up with a little gem that is relevant for those who live in really dry areas. Xeriscaping is landscaping for dry conditions that allows for gardens that need little or no extra irrigation. It has often been criticised for not being aesthetically pleasing but, where water conservation is an issue, it may be the only method that permits a garden of sorts.
Put simply, a xeriscape will contain plants that thrive in dry conditions. These tend to be things like cacti and agaves and some herbs and desert varieties – plants with deep roots, grey, fluffy leaves that reflect the sun or succulent leaves that store water. Water and nutrient intensive species such as roses or environments such as lawns require too much maintenance and resources and so are usually rejected. When watering is needed, the water is targeted to the plant only either by hand or a drip line. To conserve water more efficiently, mulch can be applied to the soil to prevent it drying out and also to protect plant roots from the sun. Sometimes it is necessary to add compost to the soil before planting as it will improve the moisture-holding properties of the soil. A rainwater collection and saving system may also be installed somewhere within the property.
Here are a few pictures of land that has been xeriscaped. As you can see, not all of these landscapes are colourless or just full of cacti:
