To succeed at growing watermelons, you will need to utilize the warmth of the summer months. Fertilize your soil to provide it with the right sort of nutrients and be prepared to provide your seedlings with lots of water. You will also need a fair amount of acreage, as the vine shoots of watermelon plants cover a large territory horizontally.

Watermelons are believed to come from the Southern African region, but their use has spread across the globe. The excavation of Tutankhamen’s elaborate tomb in Egypt testifies to the presence of watermelon in Egypt for a minimum of three millennia. Watermelon seeds were identified within. There is evidence of the watermelon being known to the Chinese in the 10th century AD. European records refer to it during the latter medieval period and it arrived in the Americas in the 16th century. Watermelons are cultivated in various states of America, but most prolifically in Arizona, Florida, California, Texas and Georgia. Japanese watermelon farmers in the Zentsuji region have grown a new type of watermelon, which is square, for easy packaging.
Considering their bulk, you would not expect to be able to cultivate watermelons in containers, but, depending on the species, it can be done. You will need to select one of the more compact types of watermelon, though. The Golden Midget would be ideal, as it only weighs 3 pounds (1.36kg). Its flesh is golden yellow when ripe and it can be ready for harvest within two and a half months. The Solitaire watermelon is another great choice for growing watermelons within limited space. It is characterized by a hard rind, an interior without seeds and it will weigh somewhere between 3 and a half and 5 pounds (1.58kg and 2.26kg). Slightly bigger, but still manageable is the Sugar Baby watermelon. It features the familiar brown seeds and is known for its sweet taste. It hits the scale at 6 to 10 pounds (2.7kg and 4.5kg). The pot you use for growing watermelon will need to be a five-gallon size or larger. Several drainage holes will be a basic requirement and you should add a good quality mix of potting soil. If you stay in the city, you could find yourself taking on pollination duties by hand.
Some of the bigger varieties of watermelon include the Jubilee, which can weigh up to 45 pounds (20.4kg) and the Crimson Sweet, which hits the scale at between 15 and 20 pounds (6.8kg and 9kg). Distinguished by their yellow speckles, the Moon and Stars watermelons can also reach 40 pounds (18.1kg) but that is nothing compared to the Blue Rind, which could weigh four times as much.
One of the challenges of growing watermelon is knowing when they are ready to harvest. The best way, according to various sources, is to knock on its side. If there is a slightly hollow echo, you can consider it ready for the picking.
A certain family in Arizona has held the record for the largest watermelon for more than thirty years. They are the Brights, from Hope Farm. Their first write-up in the Guinness Book of Records came in 1979, which a watermelon that weighed well over 200 pounds (90.7kg). However they have since bettered their own record, not once, but twice, most recently in 2005 with a watermelon of 268.8 pounds (121.9kg). These are of the largest type of watermelon, the Carolina Cross, but growing watermelons as large as that, is not an occupation for amateurs.
