Southwest Planting tips from tucsonbotanical.org

July: Avoid planting new plants except summer wildflowers or monsoon-season crops. Collect rainwater through water harvesting. Use BT mosquito dunks in any standing water. Maintain watering for most plants, but discontinue temporarily after heavy monsoon rains. Stop watering cacti & succulents if moderate to heavy rains arrive. Prune drooping tree limbs or wind-damaged branches.
