Summer Greenhouse Crops: Heat-Loving Vegetables That Thrive in High Temps

Don’t abandon your greenhouse when temperatures soar. With ventilation and daily watering, these heat-tolerant crops will outproduce their outdoor counterparts.

Setup Essentials

• Containers ≥2 ft wide (tomatoes) or floor beds.
• Soil depth 12–18 inches.
• Water daily (minimum).
• Fans + vents mandatory—verify function.

Top Summer Performers

• Tomatoes & peppers (Solanaceae): Native to warm South America—thrive at 85°F+.
• Asian eggplants (‘Ichiban,’ ‘Machiaw’): More productive than Italian types in heat.
• Hot peppers: Freeze/dry for winter cooking. Sweet peppers freeze well too.
• Summer squash/zucchini: ‘Zucchini Tricolor Mix’ yields three gourmet varieties.
• Mediterranean herbs (oregano, marjoram, thyme): Heat-loving, low-water.
• Malabar Spinach: Indian native, twining, loves heat. Red-stemmed variety is ornamental. Leaves delicious raw/cooked—kids often prefer it to regular spinach.

Your hot greenhouse isn’t a liability—it’s a tropical paradise waiting for the right plants. Plant bold; harvest abundantly.
