How to protect your garden during a harsh summer
Use irrigation hoses and soakers.
When it's really hot outside, the best way to effectively water your garden is by using irrigation or soaker hoses. While these are slightly different from each other, they both deliver water slowly to the plants' roots, which prevents evaporation and saves water.
Irrigation hoses use flexible plastic tubing that contains little holes. Water slowly drips from these holes into the soil.
