If water really is the next oil, we’d better start hoarding it.
* Water garden less frequently but for longer duration, to give soil a good lasting soak.
* Make sure there's proper drainage, and aerate lawns to allow air and water to penetrate more deeply to the roots.
* Leave clippings on the lawn to serve as mulch, which retains moisture and suppresses weeds. Rake clippings and leaves around the base of plants.
