How 'well separated' need they be? I've created three veg beds for

insect problem.

Depending on the pest, anywhere from 20' up to several miles.

Rotating crops does no harm, and the nutrient aspect is real. It is
more about not growing crops with too much nitrogen than it is about
anything getting exhausted, though. However, unless you use large
quantities of animal manure, it isn't a major issue.



Thanks Nick! To be honest I didn't notice the original message mentioned
pests, and thought you were making a general point about rotation not being
worth doing. My mistake.
