Understanding the Southwest monsoon and plant growth timing

Unlike most of North America, much of the Southwest receives its primary rainfall in July–September (the North American Monsoon) and again in winter. Spring is often the driest time of year. Per Texas A&M AgriLife Extension, this distinct rainfall pattern means "many Southwest natives are programmed to flush growth after summer rains, not in spring like eastern species." Understanding this timing helps prevent the frustration of spring-planted natives that appear to do nothing until July.

Best planting time: fall (October–November) in lower-elevation Sonoran and Chihuahuan desert areas; late spring (April–May) at higher elevations before monsoon rains begin. Avoid planting in the heat of summer before monsoons arrive or in the brief but cold winter freezes at higher elevations.
