What This Means for Your Garden
The dominant soil in Phoenix, AZ is Sandy soil. Sandy soils drain quickly and warm up fast in the spring, giving you an early start to the growing season. The tradeoff is that water and nutrients wash through easily, so you may need to water and fertilize more often. Adding compost builds up organic matter and helps the soil hold moisture.
The pH in your area ranges from 7.8 - 8.6, which is classified as Strongly Alkaline. Alkaline soil suits lavender, asparagus, and many herbs. To lower pH for acid-loving plants, you can work in elemental sulfur or acidic compost over time.
Your USDA hardiness zone is 9b, meaning winter lows can reach around 25 degrees Fahrenheit. This determines which perennials, trees, and shrubs will survive winter in your area. Check the plant recommendations below for varieties suited to both your soil and climate.
