The mini-oasis concept for landscape design is often practiced in hot and dry climates so one can enjoy a small, lush space and save precious water by landscaping the rest of the yard with low water use natives.
This idea does not necessarily relate only to desert climates. With the world’s potable water sitting at a mere one percent, everyone should be doing their part to conserve water.
The mini-oasis concept means have a small space with water loving plants close to the house where it can be enjoyed the most. Being in a somewhat protected zone, even higher water use plants will use less. Enclosing the mini-oasis also protects plants from drying winds, which increase water use. This mini-oasis can contain such amenities as a small water feature or fountain, potted plants, and a small patch of grass.
Conserving water is everyone’s responsibility. If you are not harvesting at least some rain water, you should be. A simple garbage can collect water from your roof to be used on potted plants.
