About Yard-Long Beans (Snake Beans)

Yard-long beans (snake beans, Chinese long beans, lobia) are a heat-loving climbing bean producing tender pods up to 3 feet long. Popular across Indian, Chinese, and Southeast Asian cuisines — used in dry-fried dishes, curries, and stir-fries.

Direct sow after soil warms to 65°F. Provide a sturdy trellis — vines grow 8-10 feet. Harvest at 12-18 inches for best texture — longer pods become tough. Pick every 2-3 days during peak. Loves heat and humidity.
