Solid advice. Most of my garden is trees, btw, so I only have a small patch of land for tomatoes, peppers, etc. I like watermelons too, but I haven't planted them in years.

In the winter I'm leaving it to "rotate" to whatever grows naturally (weeds, flowers, etc).

For the time being rotation should not be an issue (3rd year intact - it's left to grow wild weeds, I cut them down once per year and then let them to rot on top of the ground. It creates a nice dark-colored soil, where next years weeds and flowers are growing with even more vigor.

If I am to plant tomatoes next year I may do an experiment. I'll plant some there and some in another patch of land and see what happens.
