A Malaysian farm says it has perfected its methods to successfully grow Japanese muskmelons, one of the world’s costliest fruits. Farmers at Malaysia’s Mono Premium Melon company said they had discovered the right mix of nutrients and treatments to grow the top quality melons. One of the methods involves workers rubbing the melons with a soft cloth. The farmers believe that doing this can improve the taste of the fruit. They also play classical music around the plants, which is thought to increase growth. Seh Cheng Siang is the director and co-founder of the farm, in Putrajaya, south of Kuala Lumpur. Every single Japanese melon that you see in our farm is almost like an art piece, Seh told Reuters news agency. Since the last century, farmers in Japan have been perfecting the art of growing the fruit. Japanese muskmelons are prized for their tastiness and exact, rounded shape. In Japan, the costly melons are sold in high-end stores as luxury products. The farmers said they aim to grow melons with the same level of quality as those sold in Japan. But the process is more difficult in Malaysia because of the country’s hot and humid climate. Japan enjoys more moderate climate conditions than Malaysia.
