What Size Pot for Watermelon?

Watermelon is a classic summertime favorite, and is great for adding to summer salads, desserts, or eating out of hand. So you may be wondering – what size pot should I use for growing watermelons?

The Size of Pot Matters

When growing any kind of watermelon, the size of your pot does matter. If the pot is too small, the vine won’t be able to get the support it needs from the soil, and the melon will not develop to its full size. On the other hand, if the pot is too big, the watermelon will be very difficult to move.

Best Pot Size for Watermelon

The best pot size for watermelon is usually between 16 to 20 inches in diameter. This size pot can provide enough room for the roots to spread out, while at the same time not being too big, so the watermelon can be easily moved.

Tips for Growing Watermelon in Pots

When growing watermelons in pots, there are some important tips to keep in mind:

  • Choose a lightweight pot – Watermelons can get very heavy, so make sure to choose a lightweight pot to avoid stressing the vines.
  • Use nutrient-rich soil – Watermelons need plenty of nutrition to grow, so make sure to use a nutrient-rich soil for your pot.
  • Provide adequate sunlight – Watermelons need plenty of sunlight, so make sure to provide at least 8 hours of direct sunlight a day.
  • Water regularly – Keep the soil consistently moist, but not soggy.
  • Fertilize – Add an all-purpose fertilizer every two weeks to encourage healthy growth and better-tasting melons.


When growing watermelon in a pot, it’s important to choose the right size pot and to provide adequate sunlight, soil, and water.
