It can be hard to imagine that anything other than cactus could grow in Arizona's 120-degree summer temperatures. Surprisingly, Arizona ranks fourth in the nation in citrus exports. Unlike most of the United States, Arizona has mild winters, rarely reaching lower than 20 degrees. These temperatures make wintertime an optimal growing season in the Valley of the Sun. For the home gardener, winter is the best time for growing vegetables.
Amend the soil by tilling in a mixture of sphagnum moss, compost and fish emulsion. The ideal blend is 20 pounds of sphagnum moss, 20 pounds of compost and 30 pounds of fish emulsion for every 1,000 square feet of ground.
Select vegetables that will succeed in Arizona's climate. The growing season for vegetables in most of Arizona is the wintertime, with planting in fall and harvesting in spring. The best vegetables for Arizona include broccoli, peppers, eggplant and spinach. Herbs such as dill and rosemary thrive in partial shade.
Organize irrigation systems that ensure consistent watering. Plant vegetables in small wells for quality deep watering.
