Answer: As long as your deck provides plenty of sunshine, you can grow Bush Sugar Baby watermelons in containers there. To give the roots plenty of room to grow, plan on using at least a 3-gallon container. Make sure the container has adequate drainage holes, and use potting soil rather than garden soil as your growing medium. Plants growing in containers need extra attention, especially during hot weather. Check the soil regularly and supply water to keep it moist, but not soggy wet. When fertilizing containerized plants it's usually best to dilute the fertilizer to half-strength and apply twice as often.
Good luck with your melons!
