Maintain daytime temperatures between 66°F and 72°F, and keep the soil consistently moist, while also providing a complete nutrient solution with an EC 2.5-3.5 for healthy growth.
Regularly inspect for pests and diseases, and consider using beneficial insects for natural control. Harvest eggplants when their skin is glossy, and remember to leave a small portion of the stem attached for the best results. Enjoy your bountiful harvest!
Quick-Growing Cucumbers
Cucumbers are a fantastic choice for summer gardens, as they grow quickly and yield abundant fruit. Opt for parthenocarpic varieties, which produce fruit without pollination—perfect for your greenhouse. Gynoecious types mostly bear female flowers, needing pollinator varieties to set fruit.
English cucumbers are long and seedless, while Beit Alpha cucumbers share similar traits. For optimal growth, maintain daytime temperatures between 75° and 80°F, ensuring humidity and ample light. Trellis your plants to maximize space and encourage larger fruits. Regular pruning improves air circulation and promotes healthy growth.

If you're short on space, try scallop or patty pan squash, which are compact and easy to manage. Notably, varieties like 'Yellowfin' and 'Bossa Nova' resist common diseases, making them reliable choices.
Hand pollination might be necessary for seed saving, but don't worry—squash grows well in high heat and humidity, perfect for your greenhouse.
With proper care, you'll enjoy a bountiful harvest!
Heat-Loving Beans and Okra
Summer heat brings a perfect opportunity to cultivate heat-loving beans and okra in your greenhouse. You can start with Tepary beans, which thrive in hot, dry conditions, or edamame, the tasty green soybeans that mature before frost. Tepary beans are known for their exceptional drought and heat tolerance, making them an ideal choice for your summer garden.
Consider yard long beans and bush varieties of Lima beans for their quick growth in high temperatures. For best results, prepare your soil with compost and mycorrhizae, soak seeds overnight, and plant them 4-6 inches apart.
Ensure good ventilation to prevent mildew and use shade cloth if temperatures rise too high. Okra, another heat-loving favorite, needs well-draining soil and consistent moisture. With proper care, both beans and okra can be delicious additions to your summer meals.
Leafy Greens and Herbs for Summer Harvests
