The Fordhook hybrid watermelon is a sweet melon that weighs 14 lbs. at maturity. The Fordhook hybrid takes just 75 days to mature, unlike other common watermelon varieties, which take 90 days or more to ripen. If you're growing the Fordhook hybrid from seed, you can start your seeds indoors about six weeks in advance by sowing the seeds in groups of five or six spaced 6 to 8 inches apart. Plant the seeds about 1 1/2 inches deep in peat pots and place them in a sunny window, watering the seeds twice a week until they sprout and are ready to plant outdoors.
Plant your Fordhook hybrid watermelon in a spot that receives full sunlight and has sandier, lighter soil. Plant in the spring, when all danger of frost has passed, and allow for about 12 square feet (about 3 feet by 4 feet) of growing space.
Dig a planting hole using a shovel for your Fordhook hybrid watermelon plant that is 3 feet wide and 1 to 1 1/2 feet deep. Make sure the planting hole is in the center of the 12-square-foot space.
Mix into the displaced soil some organic compost. If you have heavier soil, mix in some sand to lighten it.
Back fill the planting hole halfway with the amended soil. Place the Fordhook hybrid watermelon plant's root system into the planting hole so that the top of the root system is about 6 inches above the ground surface.
Fill in the rest of the planting hole with the amended soil. Gently pack the remainder of the amended soil around the plant's roots to create a small mound around the plant.
Tamp the soil around the watermelon plant gently with your hands. Water the plant generously, moistening the soil down to below the root system.
Spread a 2- or 3-inch layer of thick straw mulch on the ground around the plant when the watermelons begin to grow. The mulch will protect the melons from coming into contact with the soil, which can cause insect infestations and rot.
