Watermelon

Watermelons prefer loose, well-draining soils with a pH of 6-7. Water them deeply 1 to 2 times per week to ensure that the plant has sufficient moisture. More frequent watering may be needed during periods of high temperatures. Make sure not to over-saturate the soil, as this can lead to problems such as root rot. Aim to provide 1-2 inches of water per week in total. During hot summer months, you may need to water twice a week. As the fruits begin to ripen, water less frequently to prevent cracking.

Watermelon plants thrive in full sun, meaning they require 8-10 hours of direct sunlight each day. During the warmer months, when the sun is strongest, it is ideal to give Watermelons as much sunlight as possible. During the summer season, Watermelons should ideally receive full sun exposure throughout most of the day. In the early morning, however, some shade may be beneficial because of the intense morning sunlight. In the winter, Watermelons should receive at least 6-8 hours of sunlight per day, although additional light may be necessary depending on the weather. If the winter days are shorter or the sun is not as intense, providing the plants with supplemental lighting may be beneficial.

Watermelons should be pruned when the vines reach 8 to 12 feet in length. Pruning should be done throughout the growing season to encourage the growth of lateral vines. When pruning, about 25 to 40 percent of the main stem should be cut back, but no more than 50 percent (1). Pruning should be done in mid- to late summer, after fruiting has started. This will help keep the plants from becoming unruly and will encourage further fruit production. Make sure to remove any dead or damaged vines when pruning as well.
