Winter melon (Benincasa hispida), also known as ash gourd or wax gourd, is a popular climbing vegetable in many Asian countries. Its large, mild-flavored fruits are prized for soups, stews, and health tonics. While winter melons are often grown on the ground, cultivating them as hanging plants has proven to be not only space-saving but also highly productive when done right.
This guide shares how to grow hanging winter melons with a focus on boosting fruit production, using rice husks in the soil mix, and the surprising results that came from this approach.
1. Choosing the Right Variety and Time to Plant
For hanging cultivation, choose a winter melon variety that produces medium to large fruits with strong vines. Look for disease-resistant hybrids if possible. Winter melon prefers warm, sunny weather. In tropical or subtropical climates, it can be planted year-round, but it performs best when sown during dry, sunny months to avoid fungal problems.
Start seeds in small containers or seedling trays and transplant them once they reach 2–3 true leaves. Winter melons grow vigorously, so ensure the seedlings have a strong root system before transplanting.
2. Trellising for Hanging Growth
Winter melons are natural climbers, but when grown for hanging fruits, a sturdy trellis system is essential. Build a vertical support structure using wood, bamboo, or metal frames. A horizontal overhead net or mesh (approximately 1.5 to 2 meters above the ground) allows vines to climb and fruits to hang freely.
Make sure the support is strong enough to carry multiple large fruits, each potentially weighing several kilograms. Spacing between plants should be at least 1.5 meters apart to allow ample sunlight and airflow.
3. Soil Preparation and Rice Husk Integration
A key tip that significantly boosted fruit production in this case was the use of rice husks in the soil. Rice husks improve soil aeration, drainage, and microbial activity—factors essential for healthy root development and strong vine growth.
Soil Mix Recipe:
-
50% loamy garden soil
-
25% well-rotted compost or cow manure
-
25% rice husks (raw or partially composted)
The rice husks create air pockets that help prevent waterlogging and root rot, especially important for heavy fruiting vines like winter melon. Additionally, the slow decomposition of husks enriches the soil over time.
Surprisingly, the inclusion of rice husks also reduced the incidence of powdery mildew and root diseases. This was likely due to improved airflow around the base of the plant and better drainage, which prevented excess moisture buildup.
4. Watering and Fertilization Tips
Winter melons require consistent moisture but dislike soggy conditions. Water deeply 2–3 times a week, depending on rainfall and temperature. During flowering and fruiting stages, reduce watering slightly to encourage better fruit setting.
Fertilize every 10–15 days with a balanced organic fertilizer, such as fermented compost tea or diluted fish emulsion. Once fruits begin to form, switch to a potassium-rich fertilizer like banana peel compost, wood ash, or a diluted molasses solution. Potassium promotes flower retention, fruit swelling, and sweet flavor.
A foliar spray made from fermented rice water was also applied weekly. This not only nourished the plant through the leaves but also helped deter certain pests. The result was a stronger, more resilient plant with more flowers turning into fruits.
5. Pollination and Pruning Techniques
Hand pollination dramatically increases fruit yield. Since winter melon flowers are large and separate (male and female), use a soft brush or cotton swab to transfer pollen from male flowers to female ones in the early morning.
Prune the side shoots regularly to control vine growth and direct energy into fruit development. Limit each plant to 3–4 main vines and allow only a few fruits to mature at a time, as each fruit demands high energy from the plant.
6. Unexpected Results and Harvest
With proper care, the hanging winter melon setup produced not only more fruits than traditional ground planting but also cleaner and more uniform melons. Since the fruits never touched the ground, there was no soil rot or insect damage.
The rice husk-enhanced soil mix proved to be a game-changer. Plants grew faster, showed fewer nutrient deficiencies, and remained healthy even during prolonged rains.
Harvesting was easier as well. Ripe melons hung down within reach, and their condition was easier to monitor. Signs of maturity include a dull green skin, a waxy coating, and a hollow sound when tapped.
Final Thoughts
Growing winter melon as a hanging plant with rice husks in the soil delivers numerous benefits: higher yields, healthier plants, and cleaner fruits. It’s a sustainable approach that uses agricultural by-products while maximizing vertical garden space.
Whether you’re a backyard gardener or growing commercially, these techniques can help you achieve surprisingly successful results with winter melons.
