Living in the desert can be an especially tough challenge during the summer, oddly enough we see as many problems concerning over-watered plants as water starved plants. To help find a proper balance the table below has recommended Watering Schedules as set forth by the State of Arizona Department of Water Resources and the University of Arizona Cooperative Extension Master Gardener program. Since everyone has different watering systems, soils, microclimates, etc. please use the following as a guideline.
