2.Photo of weedsEliminate weeds before they have a chance to go to seed. “One year of seeds, seven years of weeds,” says Superintendent Emeritus of the UC Davis Arboretum and Public Garden Warren Roberts.
3.Photo of poppies and deergrassDeadhead perennials to extend bloom. When your catmint, Santa Barbara daisies, asters, and other perennials stop blooming and start going to seed, shear them back and apply a shot of water. Usually this will result in renewed bloom. This also works on California poppies.

5.Replacing plantsConsider replacing the thirstiest plants with water-saving varieties this fall. Plan to plant in fall to take advantage of fall and winter rains and cooler temperatures to help plants get established.

Irrigate in the evening and early morning to prevent water loss to evaporation. Irrigate deeply and less frequently. Watering your lawn less frequently will slow its growth and reduce the need for mowing.
