growing watermelons in containers
I have three earthboxes. I plan to grow tomatoes in the 1st, cucumbers in the 2nd, and green beans in the 3rd.
I'd like to grow watermelons in containers. However due to the fact that I'll be growing other things in my three earthboxes, I'll have to grow the watermelons in other containers. The variety of watermelon I plan to grow is called sugarbush, which is a compact, bush variety of the sugar baby that has shorter vines. In comparison to its traditional counterpart, it's more tolerant of being grown in confined spaces.
I would like to grow two sugar bush watermelon plants
in one container. What size container would I need to
grow two sugar bush watermelons without overcrowding them?
Please specify the size of the container in quarts or gallons.
I know that traditionally with squash and melons you need to create a hill for the melon or squash when you plant the seeds. However since I'm growing the watermelon in a container and the variety I plan to grow is a bush type that has short vines, would making hills still be necessary? If so, how tall do the hills have to be and how large across in diameter do they have to be?
I've also heard that watermelons like sandy soil and need to be heavily fertilized so for my potting medium, should I use equal parts of sand, manure and gardening soil?
