Crop rotation as a method of disease control doesn't work on a
small scale, and it is pretty ineffective in other ways, too.
The conventional recommendation is never to plant within 10 yards
of where you did last year - and that's the distance of the
closest points. Get real in a suburban garden.

Or on an allotment. Even the chap on our site with 6 allotments, all but one
together, would have a job to manage that.

Crop rotation isn't only to control disease. Is there a scientific
source for the 10 yard figure?

Possibly. It's only a rule of thumb, anyway, and refers to how
far soil-living parasites will travel.

But the main other reason for crop rotation is nutrition, and
that's rarely an issue, except for the most extreme gardeners.
