You're probably tired of paying for a huge water bill after a long and hot summer just trying to keep your lawn and garden green.
It's officially fall, so the days are shorter and the heat is less intense during the day. The plants in your garden are starting to use less water and going dormant.
Instead of watering your plants every four to five days, you can cut back to watering once every 10 days.
It's also good practice to let your garden dry out before watering it again. You can actually drown your plants if the ground is always wet. You will not be killing your plants at all by cutting back on the water, but helping to force them into dormancy.
Cutting back your watering will help you save some money and use less energy, so will ultimately you will help the environment too.
