What Zone Is AZ for Planting?
Arizona is a state known for its diverse climate and unique geographical features. From the low desert regions to the high mountain ranges, Arizona offers a wide range of conditions for gardening and planting. To determine the appropriate plants and gardening techniques for your area, it is essential to understand the zone in which you are located.
The United States Department of Agriculture (USDA) has developed a zoning system that classifies different regions based on their average minimum temperatures. This system, known as the USDA Hardiness Zone Map, helps gardeners identify the plants that are most likely to thrive in their specific area.
Arizona is generally divided into three main hardiness zones: zones 5, 6, and 7. However, it is crucial to note that Arizona’s diverse geography and varying elevations result in microclimates within these zones. Let’s explore each zone and its characteristics to help you determine the best plants for your Arizona garden.
Zone 5: This zone includes the higher elevations of northern Arizona, such as Flagstaff and the Grand Canyon. The average minimum temperature in zone 5 ranges between -10°F to -20°F (-23.3°C to -28.9°C). This region experiences cold winters and short growing seasons, making it more suitable for cold-hardy plants like aspen trees, lilacs, and tulips.
Zone 6: Zone 6 covers a significant portion of central and eastern Arizona, including cities like Phoenix, Tucson, and Sedona. The average minimum temperature in this zone ranges from -10°F to 0°F (-23.3°C to -17.8°C). This area has a longer growing season and milder winters compared to zone 5. Some popular plants for zone 6 include mesquite trees, desert marigolds, and agave plants.
Zone 7: Zone 7 is found in the southeastern corner of Arizona, bordering New Mexico. The average minimum temperature in this zone ranges from 0°F to 10°F (-17.8°C to -12.2°C). This region experiences mild winters and hot summers, making it suitable for a wide range of plants. Some common plants for zone 7 include citrus trees, cacti, and Mexican feather grass.
