Weeds

Desert or rock-covered landscapes are popular in Arizona because they are attractive, require low maintenance, and conserve precious water. Weeds will invade established desert or rock-covered landscapes and other non-turf landscape areas where irrigation water is applied and in response to rainfall. Weeds will also be a problem where the desert is disturbed in the process of home building or the installation of a new landscape area.

This site provides information on the management and control of these invasive weeds. It assumes the reader has some knowledge about plants. For more basic information about plants, consult Chapter 1: Basic Botany, Physiology, and Environmental Effects on Plant Growth in the Arizona Master Gardener Manual, produced by the University of Arizona Cooperative Extension.
