Fresh seeds only Original Sugar Baby Watermelon Seeds 25 Seeds Heirloom Open Pollinated USDA Zone 3-12 One of the best known icebox melons is ‘Sugar Baby’. This heirloom watermelon was introduced in 1956 and has been earning fans ever since. Like many icebox types, ‘Sugar Baby’ ripens 8- to 12-pound fruits in 75 days (compared to 120 days for a full-size watermelon). Even though fruits are small, they’re packed with full-size flavor and sweetness. Growing Instructions: In cool climates, watermelon seeds should be started indoors, but no sooner than a month before transplanting. Plant 3 seeds per pot, 1/4" deep. Provide heat to keep the soil at least 80-85°. Cut off all but the strongest seedling as soon as true leaves appear and transplant about a week after the last spring frost. Make hills about 6-8' apart and put 2-3 plants in each hill. In warm climates, direct sow the seeds once the soil temp reaches 75° planting 6 seeds per hill with 6-8' space in all directions. Thin to the strongest 2-3 plants as soon as the seedlings appear. Watermelon should be planted in full sun and rich, loose soil. Young seedlings may benefit from black plastic to warm up the soil. As soon as the vines develop, add a layer of mulch to conserve water, control weeds, and protect the melons from soil contact.
