1. Automatic Shut-Off Nozzle for Hoses.
This will help you control the flow of water so that it’s never running unnecessarily.
2. Use Leftover Water for Plants.
Water used to wash vegetables can be caught in a pot (or tin can), saved and used for watering the garden.
3. Lay Organic Mulch Around Plants.
2-4 inches of organic mulch around plants and shrubs can reduce evaporation from the surface of the soil. This will allow you to them less often.
