Watermelons are ideal for introducing youngsters to the joys of gardening! The heritage variety 'Moon and Stars' is particularly interesting with its golden-yellow marbled foliage. Melons are dark green with flecks of yellow, round, and between 4 and 7 kg on average. The flesh is a brilliant red, delicious and sweet. Seeds take 10 days to germinate and the fruit is ready to harvest approximately 100 days later. Plants need plenty of heat and fertile soil.
