How to Plant Watermelons in a Big Pot


If you enjoy the fresh taste of ripe watermelon still warm from the sun, but don't have the growing space available in your yard, then growing watermelons in a container may be an option. To plant watermelons in a big pot you'll want to select a dwarf variety such as Bush Sugar Baby or Garden Baby and have a large-enough pot to support it. After planting, you'll need to keep the plants well watered and fed to get the best, largest watermelons possible.

Step 1

Layer the bottom inch of your pot with small gravel. Cover the gravel with clean potting soil and fill to within an inch of the top.

Step 2

Plant three dwarf watermelon seeds into the center of the pot, 1 inch deep; plant them 3 inches away from one another. Cover over the seeds lightly with soil. Be sure the pot is set in an area that receives full sun---at least six hours of direct sunlight each day.

Step 3

Water the soil in your pot well and keep it damp, but not soaked, as the seeds germinate over the next two weeks. When the seedlings are 6 inches tall, thin out the weakest one, leaving two plants to grow in your pot.

Step 4

Feed your seedlings with a high-nitrogen fertilizer---10-0-0 strength---with a liquid fertilizer or granules. Feed the watermelon each month to encourage good growth and fruit production.

Step 5

Water the watermelons two to three times a week to keep the soil moist inside the pot. The larger your plants become, the more water they will use, so regular watering is crucial to growing successful watermelons.

Step 6

Allow the vines of your watermelon plant to cascade over the edges of the pot as it grows larger. Make sure your pot is in a location where there is room for the vines to grow and not be cramped or blocked from sunlight.

Tips and Warnings

  • Avoid wetting the leaves of your watermelon plant when you water to keep the chance of disease down.
