Wondering about Arizona gardening in July? All of these pictures come from my garden in Mesa, Arizona this month.

Arizona Gardening in July
Which fruits and vegetables are growing in the garden beds in July?
Melons are producing well. This year I planted Hopi yellow watermelon, Chimayo melons and cantaloupe. Be sure to water regularly and keep the plant healthy. Provide a trellis or ladder for the growing plants to keep them up off the ground.
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.
It’s been a great year for 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.
WHICH FLOWERS ARE BLOOMING AROUND THE YARD IN JUly?
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.
Globe Amaranth thrives in the heat with consistant watering. I like to harvest the flowers for cut flowers. I’ve planted this in my flower beds as well as throughout my garden beds to attract pollinators.
Tecoma is in full bloom and doesn’t mind the heat. Hummingbirds and pollinators love it. This is a great addition to an Arizona garden landscape.
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.
WHAT GROWS ON ARIZONA FRUIT TREES IN JUly?
Anna apples are finishing up. The birds got a few of them before I could harvest them. We had a smaller crop this year. I think it was due to the milder than normal winter and lack of winter and spring rain.
Citrus is developing on all the citrus trees throughout the yard. Last month the trees self-thinned and the fruit that is left on the tree is growing well. The monsoon rains and higher humidity this month are appreciated by the citrus trees.
Several citrus trees around the yard have sun damage on the leaves from the hot dry June we had this year.
WHICH HERBS GROW IN ARIZONA GARDENS IN july?
Lemon grass is growing fast. I’m a newbie at this herb and still learning what to do with it. Prairie Homestead has a great article on using and growing lemongrass if you would like more information.
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.
Basil is the champion herb of summer. Be sure to keep it pruned and try different varieties to mix things up.
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. We have had a few monsoon storms so far this year which is much needed. 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.
What I'm planting in July:
- Pepper and tomato transplants at the end of the month or beginning of August
- Snap beans in the middle of the month
- Carrots at the end of the month or beginning of August
- You can also plant pumpkin, corn, winter squash, blackeyed peas, and a final planting of sunflowers or cantaloupe for the year.
