Is It Possible to Grow Watermelon in a Pot?

Successfully growing watermelons in pots starts before you even plant your watermelon seed. Choose a pot that will be large enough for your container watermelon to thrive. Watermelons grow rapidly and require plenty of water, so it is recommended that you go with a 5-gallon (19 kg) or larger size container. 

Watermelons require full sun for proper growth. Choose a location where watermelons receive eight to 10 hours of direct sunlight. The plants need sun to remain healthy and productive. 

Healthy watermelon vines produce 2-4 fruits per plant. The vines produce both male and female flowers. Both are needed to set fruit and there are fewer female flowers compared to male, about one female for every seven males.
