How to Grow Kiwano in Ireland
Kiwano, also known as horned melon, is an exotic fruit native to Africa that can be grown successfully in Ireland with some care. Its unique spiky orange skin and vibrant green interior make it a fascinating addition to any garden. Kiwano thrives in warm conditions, so while Ireland’s climate can pose challenges, it’s possible to cultivate this tropical fruit in a greenhouse or polytunnel. We grow them since ten years inside our polytunnel and they yield consistently. It is a crop that we always recommend because it is an easy one.
Getting Started
Start by planting kiwano seeds indoors in late spring like your cucumber. Use peat-free compost and place the seeds in small pots, keeping them warm (20-25°C) and moist until germination occurs. Once the seedlings are strong enough, transplant them into larger pots or beds in your greenhouse or polytunnel.
Growing Tips
Kiwano plants need plenty of sunlight, warmth, and water to thrive. They grow as vines, so provide a trellis or support system. Water regularly but avoid waterlogging, as the roots can rot. Feeding the plants with a balanced liquid fertilizer (like fermented nettles extract and vinasse) every two weeks will encourage healthy growth and fruiting.
Harvesting
Kiwano fruits are ready to harvest at the end of September, around 5 months after planting. The fruit can be stored for weeks, making it a practical and exotic addition to your homegrown produce. Harvest them before any frost and keep them inside your kitchen. They are ready when they go bright orange which usually happens around Christmas. The flesh is then bright green.
Why Grow Kiwano?
Not only is kiwano visually stunning, but it’s also packed with nutrients like vitamin C and antioxidants. It’s perfect for smoothies, salads, or as a unique decorative fruit.
Try mixing the pulp of the kiwano with a little bit of cider vinegar, honey, salt and pepper. Enjoy!
