Let’s dig into the specifics of 20 tropical vegetables to plant in June, discussing their temperature tolerance, ideal planting times, and additional tips to make the most of your garden.
Okra
Okra is a quintessential summer vegetable, thriving in hot weather. It can tolerate temperatures between 75°F and 95°F, making it perfect for the summer months. Zone 9 typically allows for direct sowing in June, after the last frost. Plant seeds 1 inch deep in fertile, well-drained soil with plenty of sun exposure. Space plants about 12-18 inches apart to allow for their bushy growth.
Once established, okra can produce an abundance of immature pods throughout the summer. Make sure to harvest regularly every two to three days to encourage continual production. Okra is versatile in the kitchen; you can fry, steam, or even pickle it. Adding this southern favorite to your garden not only brings culinary diversity but also colorful stalks that can grace your garden space.
Sweet Potatoes
Sweet potatoes thrive in warm soil and temperatures between 65°F and 95°F, making them a great fit for Zone 9. June is an ideal time to plant sweet potato slips; you can start harvesting in late summer to early fall.
Plant sweet potatoes by digging a trench about 4-6 inches deep and placing the slips about 12 inches apart. They require well-drained sandy loam or loamy soil and should receive full sun for optimal growth. Once they start growing, their leafy vines will provide ground cover, which can also help suppress weeds. As the sweet potatoes develop underground, you can look forward to a diverse array of flavors in your cooking, from sweet potato fries to casseroles.
Eggplant
Eggplants enjoy the heat and can thrive in temperatures ranging from 70°F to 90°F. Planting them in June in Zone 9 ensures they receive plenty of sunlight and warmth. Start seeds indoors about 8-10 weeks before the last frost, or you can sow them directly in the garden once the soil has warmed.
Eggplants need fertile, well-draining soil and should be spaced about 18-24 inches apart for ample growth. They often bear fruit throughout the summer, typically needing about 70-90 days from planting to harvest, depending on the variety. With their globe-like shapes and stunning colors ranging from deep purple to white, eggplants can be the stars of your garden and kitchen alike. Prepare them grilled, roasted, or stuffed, and let their rich flavors shine in your summer dishes.
Peppers
Peppers are incredibly versatile and can withstand high temperatures, generally thriving between 70°F and 90°F. In Zone 9, June is perfect for planting both sweet and hot varieties directly in the garden, once frost danger has passed.
