Vegetables growing in the low desert Arizona garden in July
Several varieties of peppers are producing in the garden this month. These serrano peppers take the heat well. Bell peppers can get sunburned if fruits get direct sun; provide some shade if scalding is a problem.
The last of the tomatoes on the vine have ripened. It is too hot for pollen to be viable for new tomatoes to develop. After removing the final fruits, I pulled out the plants and will plant new ones at the end of the month.
Cucumbers. I’ve harvested a steady supply of Japanese, Collier, Lemon and Burpless cucumbers. Cucumbers do best on a trellis, with even watering and mulching with compost. Pick cucumbers young and pick them often to encourage production. Production slows or even stops this month as temperatures heat up. Pull plants if necessary if pests or diseases are an issue.

Arizona gardening in July wouldn’t be the same without sunflowers! They are everywhere in my yard and I love it. There are many reasons to plant sunflowers: they provide shade, can be used as a trellis, attract wildlife and pollinators, and they are so simple to grow from seed in nearly any spot in your yard.
Learn how to grow and harvest sunflower seeds in this article I wrote for Kellogg Garden.
Yellow Dot is a vigorous ground cover that grows rapidly in well-drained soil and can grow in full sun or shady areas. It looks great most of the year and provides a living mulch to trees in the heat of the summer.
Zinnias are a champion of Arizona gardening in July. They are best grown from seed; you can plant them all summer long. Don’t get water on the leaves as they can burn in the sun if you do this. Give them consistent moisture and enjoy the lovely blooms! They are also an excellent cut flower.
Ornamental Sweet Potato Vine is a fast grower and available in several different colors. Great greenery and filler even in the hottest months. This vine is easy to start from cuttings; root in water first and then plant, it’s that simple. Regular watering keeps it lush.

Rosemary is doing great and doesn’t mind the heat. It’s best not to prune it this month, but you can harvest it as needed for recipes.
Low Desert Arizona Garden in July To-Do List:
- Fertilize sweet potatoes with a balanced fertilizer.
- Clear out squash and other plants that have stopped producing or are showing signs of heat stress and disease to make room for monsoon and fall planting.
- Don’t prune or fertilize most plants. Most are in summer dormancy in order to survive. Pruning can expose new parts of a plant to sunlight damage, and fertilizing can cause stress in plants as well.
- Water evenly. Hopefully the monsoon humidity and added moisture comes to the low desert this month. A rain gage is helpful to see how much rain you received. If you measure .5 inches of rain, turn off your water timers! You can also insert a screwdriver into grass or rocks to determine whether to water. If it passes easily into the soil, you can wait a day or two to water. Monitor plants for signs of stress, and make sure plants are getting enough water and have good drainage.
