Unveiling the Moon Melon: Can You Really Grow This Garden Rarity?
The allure of the exotic and unusual often captivates gardeners, and the “moon melon,” also known as the Densuke watermelon, certainly fits the bill. This rare Japanese watermelon is renowned for its exceptional sweetness, crisp texture, and striking black rind. But can you actually grow a garden variety of this moon melon, and what makes it such a rarity?
What is the Moon Melon? The Densuke Watermelon Explained
The Densuke watermelon is a specific cultivar of watermelon grown exclusively on the island of Hokkaido, Japan. Its name, “Densuke,” doesn’t literally translate to “moon melon,” but its dark, almost black rind, coupled with its high price tag and mystique, has led to the popular (though somewhat inaccurate) moniker. The authentic Densuke is known for its incredibly sweet flavor, described as having a distinct crispness and a unique sweetness that sets it apart from common watermelons. The flesh is typically a deep red color. This moon melon is truly a rarity.
Why is the Densuke Watermelon So Expensive?
Several factors contribute to the Densuke watermelon’s hefty price tag. These include:
- Limited Production: Densuke watermelons are grown in very small quantities, with only around 100,000 being produced each year. This limited supply drives up the price considerably.
- Geographic Exclusivity: The Densuke watermelon is only grown in Hokkaido, Japan. The specific soil and climate conditions of this region are believed to contribute to its unique flavor and texture. Trying to grow a garden version outside of this region presents challenges.
- Rigorous Quality Control: Each Densuke watermelon undergoes strict quality control measures. Only the watermelons that meet the highest standards are sold under the Densuke name.
- Symbolic Value: In Japan, high-quality fruits like the Densuke watermelon are often given as gifts, particularly during special occasions. This cultural significance further contributes to their perceived value.
Can You Grow a Moon Melon in Your Garden?
The question on every gardener’s mind: can you actually grow a garden variety of the moon melon? The answer is complex. While you can’t legally grow *authentic* Densuke watermelons outside of Hokkaido (due to intellectual property rights and geographical limitations), you *can* attempt to cultivate watermelons that resemble the Densuke in appearance. Seeds marketed as “black watermelon” or “Densuke-type” are available, but it’s crucial to understand that these are not the genuine article. They are often hybrids bred to mimic the dark rind and sweetness of the original Densuke.
Growing “Densuke-Type” Watermelons: A Guide
If you’re eager to try growing your own version of the moon melon, here’s a guide to help you succeed:
Seed Selection
Carefully select seeds from reputable suppliers that are specifically labeled as “black watermelon” or “Densuke-type.” Be wary of seeds claiming to be “genuine Densuke” unless they come directly from Hokkaido (which is highly unlikely for international buyers). Read reviews and research the supplier to ensure you’re getting a quality product.
Soil Preparation
Watermelons thrive in well-drained, sandy loam soil with a pH of 6.0 to 6.8. Amend your soil with compost or well-rotted manure to improve drainage and fertility. Ensure the soil is warm, as watermelons are heat-loving plants.
Starting Seeds
You can start watermelon seeds indoors 4-6 weeks before the last expected frost. Sow seeds ½ inch deep in individual pots filled with seed-starting mix. Keep the soil moist and maintain a temperature of 70-80°F (21-27°C). Once the seedlings have developed a few true leaves, they can be transplanted outdoors after the danger of frost has passed.
Transplanting and Spacing
Choose a sunny location with at least 6-8 hours of direct sunlight per day. Space watermelon plants 3-4 feet apart in rows that are 8-10 feet apart. Dig a hole slightly larger than the root ball of the seedling and gently place the plant in the hole. Backfill with soil and water thoroughly.
Watering and Fertilizing
Watermelons need consistent moisture, especially during fruit development. Water deeply and regularly, aiming to keep the soil evenly moist but not waterlogged. Fertilize with a balanced fertilizer every 2-3 weeks. Reduce fertilization as the fruit ripens to avoid compromising the sweetness.
Pollination
Watermelons require pollination to set fruit. If you notice that your plants are producing flowers but not fruit, you may need to hand-pollinate them. Use a small paintbrush to transfer pollen from the male flowers to the female flowers. Female flowers have a small swelling at the base of the flower that will eventually develop into a watermelon.
Pest and Disease Control
Watermelons can be susceptible to various pests and diseases, including aphids, squash bugs, and powdery mildew. Monitor your plants regularly and take action promptly if you notice any signs of infestation or disease. Use organic pest control methods whenever possible. Crop rotation can also help prevent soil-borne diseases. Protecting your moon melon attempt is crucial.
Harvesting
Watermelons typically take 80-90 days to mature. To determine if a watermelon is ripe, look for these signs:
- The tendril closest to the fruit turns brown and dry.
- The underside of the watermelon (where it rests on the ground) turns yellow.
- The watermelon sounds hollow when thumped.
Use a sharp knife to cut the watermelon from the vine, leaving a few inches of stem attached.
The Reality of “Moon Melon” Taste and Expectations
It’s important to manage your expectations when growing “Densuke-type” watermelons. While these varieties may resemble the Densuke in appearance, their flavor and texture may not be identical to the authentic Japanese watermelon. Factors such as soil conditions, climate, and growing practices can all influence the taste of the fruit. Even the best “Densuke-type” watermelon grown outside of Hokkaido may not fully replicate the unique characteristics of the original moon melon. The unique characteristics of the Japanese moon melon are difficult to replicate when you grow a garden version.
The Allure of Rarity and the Joy of Gardening
Despite the challenges of replicating the true Densuke experience, growing “Densuke-type” watermelons can still be a rewarding experience. The dark rind and the promise of exceptional sweetness add an element of excitement to the gardening process. Even if the fruit doesn’t taste exactly like the real thing, you can still enjoy the satisfaction of growing your own food and the unique flavor of a home-grown watermelon. The quest to grow a garden moon melon is a journey in itself.
Conclusion: Embracing the Challenge of Growing a Garden Rarity
While the authentic Densuke watermelon remains a rare and expensive delicacy, the availability of “Densuke-type” seeds allows gardeners to experience a taste of this exotic fruit. By following the tips outlined above, you can increase your chances of successfully growing a dark-rinded watermelon that is both visually appealing and delicious. Remember that replicating the exact taste of the original Densuke may be challenging, but the joy of gardening and the satisfaction of harvesting your own home-grown watermelon are rewards in themselves. Embrace the challenge, experiment with different varieties, and enjoy the journey of growing your own garden rarity. The pursuit of the moon melon is a testament to the allure of the unusual in the gardening world. Even if you don’t achieve perfect replication, the attempt to grow a garden version is a worthwhile endeavor.
