Heirlooms to Plant in July

As we head into the hottest part of summer it may feel like the only garden chores left are weeding, watering, and harvesting. However, you can still be planting some summer vegetables, fall crops, and even flowers. If you’d like to squeeze a little more out of your garden this year consider planting some of these heirlooms this July.

Summer Crops

To get good production from summer crops pick quick-growing, heat-tolerant varieties. Beans, southern peas, summer squashes, cucumbers, swiss chard, and collards are all great choices for second successions or empty spaces in your garden.

In the heat, remember to provide consistent water especially while seeds are germinating. This will greatly improve your yields.

Straight Eight Cucumber 

An old standby, this variety won All-American Selections in 1935! It’s incredibly dependable, high-yielding, and ready to harvest in just 57 days!

Creel Crowder Southern Pea (Cowpea)

Ready to harvest in just 61 days this variety is a family heirloom of Cheryl and Garey Hughes, from Garey’s great-uncle R.E. Creel, a truck farmer in Warrior, Alabama in the 1930s. They’re semi-vining plants that are very productive.

Georgia Green (Georgia Southern Creole) Collards

This pre-1880 variety is resistant to both heat and frost and tolerates poor soils. It’s perfect for areas where growing cabbage is difficult.

Pencil Pod Black Wax Bush Snap Bean

This variety was developed in 1900 by crossing ‘Improved Black Wax’ and ‘Black Eyed Wax’. It’s not as productive as modern wax beans but it is extremely tolerant of high heat. Ready in 52 days, it’s great for fresh eating and canning.

Benning’s Green Tint Summer Squash

Developed around 1914, this is one of the hardiest and most beautiful varieties of Patty Pan squash. It’s ready in 52 days and is best harvested small.

Fall Crops

July and August is actually the perfect time to start a lot of fall crops. The heat can make it a bit tough though. To improve germination and yields, keep your soil moist and use tricks like shade cloth or covering seeds with cardboard until they germinate.

Early Flat Dutch Cabbage

The best storage cabbage, this variety dates back to before 1875 and possibly before 1855. It’s heat resistant and the 6-10lb heads are great for sauerkraut.


Growing a few autumn flowers can keep your garden looking full and fresh until the end of the year. It’s also a great way to help pollinators.
