In this guide, we will explore what to plant in July in Michigan, focusing on vegetables, flowers, herbs, and landscape plants suitable for this time of year.
Vegetables To Plant
The mid-summer window presents a fantastic opportunity for a second round of vegetable planting, especially for crops that love the heat or those that grow well in cooler weather yet can still be planted in July. Here are ten vegetables to consider for your garden this month.
Beans (Phaseolus vulgaris)
Beans, whether bush or pole varieties, thrive in warm soil and can be planted until mid to late July in Michigan. These plants prefer temperatures ranging from 70°F to 90°F. Beans grow quickly and can produce a promising harvest even with a shorter growing season. Ensure the soil is well-drained and rich in organic matter to promote optimal growth and productivity.
Carrots (Daucus carota)
July is also an excellent time to sow carrot seeds for a fall harvest. Carrots can tolerate temperatures as low as 45°F and prefer cooler soil, around 60°F to 70°F. In Michigan, you can start planting carrot seeds in mid to late July, allowing them to mature as temperatures cool in the fall. Be sure to sow seeds ¼ to ½ inch deep in loose, well-aerated soil, ensuring they have adequate space for root expansion.
Cucumbers (Cucumis sativus)
Cucumbers are one of the quintessential summer crops that can be planted until mid-July. Preferring warm weather with temperatures from 70°F to 95°F, cucumbers grow quickly and can yield an abundant harvest in just 50 to 70 days. These vines require ample sunlight and consistent moisture, so make sure to mulch around the base to retain humidity and suppress weeds.
Radishes (Raphanus sativus)
Radishes are a fast-growing option that can be sown throughout July. These hardy little root vegetables thrive in cooler weather and can germinate with soil temperatures as low as 45°F. Plant seeds about half an inch deep for a quick turnover, and expect to harvest your first crop within three to four weeks. Additionally, radishes help break up compact soil, providing an excellent service in mixed plantings.
Beets (Beta vulgaris)
Planting beets in July can yield a fantastic fall crop. Beets prefer temperatures between 50°F and 85°F and have the unique ability to grow well into cooler weather. When planting, space seeds about 2 inches apart and 1 inch deep, ensuring you provide adequate moisture to prevent them from becoming woody. You can start harvesting baby beets in about 50 days.
Turnips (Brassica rapa)
Turnips, especially hardy varieties, can be planted from mid to late July. They thrive in moderate climates, growing best in temperatures from 50°F to 75°F. With a quick turnaround of about 60 days, turnips offer nutritious greens above ground as well as a delicious root crop. Ensure you plant them in well-drained soil, and you will be rewarded with an impressive yield.
Squash (Cucurbita pepo)
Summer squash, including zucchini, can be planted in July for a rolling harvest throughout late summer. These plants thrive in warm conditions between 70°F and 90°F and can be harvested in about 50 to 70 days. To ensure good air circulation, plant squash seeds with enough space (2 to 3 feet apart) between them and provide regular watering for optimal fruit development.
Kale (Brassica oleracea)
Kale is a leafy green that can be sown in early July for a late summer to fall harvest. It grows best between 60°F and 75°F and can withstand frost, making it one of the most resilient crops for Michigan’s unpredictable summer weather. You can expect to start harvesting kale leaves in about 55 to 75 days after planting. Choose a spot with full sunlight and well-drained soil to ensure healthy growth.
Peas (Pisum sativum)
While peas are typically planted earlier in the season, you can still plant certain late-maturing varieties in July for a fall harvest. Peas prefer cooler temperatures, ideally between 55°F and 70°F. If you’re opting for this late planting, select snap peas or snow peas, which can handle the heat better than garden peas. Ensure they have support, as they naturally climb, and provide a good amount of water for optimal yield.
Swiss Chard (Beta vulgaris subsp. cicla)
Swiss chard is an excellent choice for July planting due to its heat tolerance and ability to flourish in diverse conditions. It thrives at temperatures ranging from 50°F to 85°F and can be harvested throughout the summer and fall. Chard seeds can be sown about 1 inch deep and 2 to 4 inches apart. They have a relatively quick maturation time of roughly 50 to 60 days, allowing for continued harvests as other crops begin to fade.
