Hi,
Just to jump back in here real quick, I have a couple tips for you and questions. How's the sunlight--veggies need a lot, like 6-8 hr. Watermelon needs a lot of heat and spaceand a long season, it's not one of the easiest to grow...
Re: your bed…
If it's any help, I started a blog last month to help anyone grow organic food, especially if you've never done it.
You can check it at

Growing organic food and sharing that knowledge and food with as many people as possible through hands-on consulting and through info on my blog. Anyone can grow some of their own food organically even with no land and very little money, and it's fun.
