Watermelon cultivation started thousands of years ago, but didn't start in the United States until the 1500s. These large fruits come in several different varieties and can be as light as five pounds or as heavy as 200 pounds. No matter what the variety is, watermelons have a light, sweet flavor that is perfect for cooling down on a hot day. They can grow in almost any climate that has warm summers, but they must have ideal growing plots to do well.
Choose a spot in your garden that gets full sunlight. Watermelons do best in hot and humid environments.
Dig a hole about a foot deep and four feet wide. Set the soil aside in a pile. Break it up with a shovel to remove large clumps.
Mix one part compost to three parts soil. The compost will add nutrients to the soil as well as help it drain.
Fill the hole with the soil and compost mixture. Arrange the mixture so it makes a hill. Ideally, the top of the hill should be about four inches higher than the ground surrounding it.
Bury four watermelon seeds an inch deep at the top of the hill. Water the soil so it is moist.
Keep the soil moist at all times. It is especially important that watermelons have moist soil.
