Arizona Master Gardener Manual Planting Calendar
The Southwest's varied topography and climate create myriad growing conditions and planting seasons. What is ideal for one gardener may be problematic for another living just a few miles away. There is no substitute for experience and keeping a record of what occurs in your particular microclimate! As a general guideline, the Arizona Master Gardener Manual includes a Planting Calendar divided into six elevation zones ranging from 10 feet to over 6000 feet. Although based on Arizona's conditions, it works as a starting point for all Southwestern gardeners. If you live out of state, check with your County Cooperative Extension office. Many have planting calendars for their area.
