Growing a Watermelon in a Pot

Watermelons are widely grown outdoors in warmer regions of the United States. But many gardeners in cooler regions often want to know: Can I grow a watermelon in a pot?

The answer is yes, you can successfully grow a watermelon in a pot or a large container – you just have to create the right conditions. Here are some tips to get you started:

Choose the Right Pot

A watermelon is a large vining plant with a vigorous root system, so pick a large pot. It should be at least 20 gallons or 80 liters in capacity and with drainage holes.

Water and Fertilizer

The plant will require regular watering, which means the soil will need to be moist, but not wet. Aim to water deeply but infrequently and monitor the root zone for moisture.

Watermelon needs regular feeding, especially when the fruit begin to develop. Use an organic fertilizer and follow the package instructions.

Support and Training

Watermelon vines normally sprawl across the ground, so you will need to provide them with support. Install a trellis or similar support for the watermelon to grow up, to make the most of the vertical space.

Once vines reach almost two feet in length, begin regularly training them to the support.

Fight Pests and Diseases

Monitor the watermelon plant closely and act immediately to control any pest or disease issues. Look for symptoms such as poor growth, yellowing leaves, or spots on leaves and stems.


Your watermelon should mature in 70 to 100 days, depending on the variety. When the fruit ripens, it should have a dull thud sound when tapped. Pick the watermelon and enjoy your homegrown crop.

Growing a watermelon in a pot takes dedication and a bit of creativity. But by following these steps, you should be able to enjoy your homegrown watermelon in the comfort of your garden or patio.
