The winter gourd plants need 110 days of frost-free weather and grow ideally well in climates with an average daytime temperature below 90 degrees. Winter melons prefer full sun and require a fair amount of water.

When to Start Winter Melon Seeds

Winter melon seeds can be direct sown in a prepared garden two weeks after the last frost. Gardeners can get a jump on the season by starting seeds indoors six weeks before planting. Winter melon seedlings are ready when four to six leaves have appeared, and the ground is above 60 degrees F. You will have the most success using biodegradable seed starting pots as it’s easy to damage the delicate roots of young seedlings.

How to Plant Winter Melon

Sow four to six seeds 1-inch deep in mounds or depressions 24 inches in diameter. Use a 6-12 inch mound if you plan to irrigate or if you live in a climate with summer rainfall. A depression helps provide plenty of water in dry climates. Make a depression about two inches deep and create a rim around the depression.

Thin the seedlings when they have developed 2 or 3 true leaves so that you have 2 or 3 of the strongest plants growing. Clip the thinned seedlings off at the ground with shears. If you are transplanting, you can place one to three plants in each mound.

Soil and Water for Winter Melons

Chinese ash gourds will grow in various soils but will do best when planted in loose, well-draining soil that has been turned with compost. An ideal soil pH for winter melons is 6.0-6.8. Aged manure added to the soil during the autumn previous to planting will produce strong winter melon plants. Use an organic fertilizer tea every two to three weeks during the growing season.

Ash gourd vegetables require frequent and consistent watering. Inconsistent watering will lead to reduced yield and growth of plants. Watering should be done on a set schedule so that the soil stays moist but not wet. Avoid spraying water on leaves to prevent mildew and bacterial growth.

When to Harvest White Gourds

Winter melon gourds take a long time to grow. You should be ready to harvest after about 110 days of growth. Winter melons are ready to harvest when the mature fruit has an ashy appearance, and the stem has withered and turned brown. The ripe melon will smell sweet on the stem end and will be large and heavy.

You may want to harvest immature winter melons, too. The flavor is somewhat sweeter from younger melons. As your winter melon plant grows, pluck off some of the yellow flowers so that each vine has no more than four ash gourd vegetables growing on it. The winter melon flowers can be cooked and eaten.

Pests and Diseases Common to Winter Gourds

Winter gourd melons are susceptible to many types of pests and diseases, many of which are easy for the home gardener to prevent and avoid. Once your winter melon plants begin showing signs of illness or disease, you’ll need to act quickly to save the plant and prevent problems from spreading to other plants in your garden.

– Pests

The most common pests that impact winter melon cultivation are aphids, spider mites, and caterpillars. Of particular importance, winter melon plants attract cucumber beetles. Cucumber beetles will eat little holes in the leaves, but the biggest problem is their role in transmitting wilt to other plants. Wilt is a bacterial disease carried by cucumber beetles that can quickly kill large areas of your garden.

The best way to treat your garden for pests like aphids and cucumber beetles is to use diatomaceous earth sprinkled lightly over the crops between waterings. You must remove infected plants carefully, and you should make an effort to prevent spreading pests to other plants. You can also use a 70% neem oil and water mixture sprayed on plants to kill spider mites, aphids, and hundreds of other pests attracted to winter melon plants.

– Diseases

The most common cause of diseases that impact winter melon plants is improper watering. Plants like the winter melon are highly susceptible to mildew caused by leaves getting wet when conditions don’t allow them to dry quickly. You should always avoid wetting the leaves of trailing vine plants like the winter melon.

Overwatering increases the likelihood of creating perfect conditions for root rot. Plants suffering from root rot will look sickly, yellow, and will have bloated vines and leaves. Once root rot has become a problem, you will need to remove the plant from your garden, taking care to avoid spreading soil to other plants. Do not compost plants that show signs of root rot because the fungus will spread through your compost and continue to infect crops for several years.

How to Use Winter Melon

Most winter melon is cultivated for the large fruit used in many soups, stews, curries, and other Asian dishes. The rind of the winter melon is thin and is easy to peel. Cut winter melon into chunks before using it in dishes. Because winter melon doesn’t have much of a flavor on its own, many dishes use it to enhance seasonings that the fruit’s meat picks up while cooking.

Winter melon blossoms can be plucked when fully developed and excellent when stuffed with rice or chorizo and fried. The flowers have a flavor similar to spinach and add important nutrition to your diet. Flowers can also be sauteed to add color and texture to many dishes.

Tender young shoots and tendrils can be snipped and used cooked or raw in salads. Many recipes that use mature vines call for the cook to remove the hairs with a vegetable peeler. Vines and tendrils can be sauteed for a unique addition to many stir fry recipes.

A popular snack in many parts of Asia is dried and candied winter melon. The fruit’s natural sweetness is enhanced by the drying and candying process, making for a delicious snack that still packs a nutritious punch. You can use a food dehydrator at home to dry winter melon to make candied melon slices.

How to Preserve Winter Melon

When you harvest winter melon, avoid the temptation to wash the fruit. Unwashed, a winter melon will remain edible for up to five months when kept in a cool, dark place.

Sliced winter melon must be wrapped in plastic wrap and kept in the refrigerator, where it will last five to seven days. Flowers and young tendrils should be used immediately after harvest.
