Winter Melon

Benincasa hispida

vegetable

Winter melon, also called wax gourd or ash gourd, is a sprawling warm-season vine of the gourd family that produces enormous fruit - oblong gourds that can reach 10 to 40 pounds. Young fruit is covered in fine fuzz, while mature fruit develops a powdery white waxy bloom that seals it so well it stores for 6 to 12 months, far longer than almost any other garden vegetable and the source of the name. The mild, white, faintly sweet flesh is a staple of Asian kitchens, simmered in the classic winter melon soup (often served in the hollowed-out gourd), stir-fried, or candied into sweets. Despite the name it is a hot-weather crop, needing a long warm season of 120 to 150 days to mature its giant fruit.

✅ Plant alongside

Good neighbors that attract beneficial insects or deter pests

• Corn: A tall partner that shares the warm-season bed without crowding the ground-running vines
• Provider Bush Bean: Fixes nitrogen for the heavy-feeding, large-fruited vine
• French Marigold: Helps deter nematodes and some cucurbit pests around the planting

🛡️ Pest & disease prevention

Proactive ways to stop trouble before it starts. Tap a name with an arrow for its full guide

• Cucumber beetles →

  Use row cover on young plants, hand-pick, and keep the area weed-free to limit bacterial wilt they spread

• Squash bugs →

  Hand-pick adults and crush egg clusters on leaf undersides; clean up old vines at season end

• Aphids →

  Rinse colonies from new growth and encourage ladybugs

• Powdery mildew →

  Space the sprawling vines for airflow and avoid wetting the foliage late in the day

🌾 Harvest & storage

Winter melon is ready about 120 to 150 days from planting, when the fruit is full-size and a mature gourd has developed its chalky white waxy coating; the fuzz of young fruit gives way to that smooth wax. Cut the gourd with a few inches of stem and handle it gently to avoid bruising the rind. For long storage, cure mature fruit in a warm, airy spot for a week or two to harden the rind, then keep it in a cool, dry place, where an intact waxy gourd holds for 6 to 12 months. Young fuzzy fruit can also be picked small and cooked right away.

🥗 Nutrition & benefits

Winter melon is among the lightest of vegetables at about 13 calories per 100 g, with a very high water content, fiber, and vitamin C plus some minerals. Mild and cooling, it is the heart of winter melon soup, simmered in broths and stir-fries where it absorbs surrounding flavors, or candied into a sweet treat; the long-keeping gourd is a valued fresh vegetable through winter.
