It doesn't sound as if he's quite understood the principles of the Organic approach.

We had the opposite from one of our neighbours, who complained that a lot of water was draining from our land down onto his, so we 'had better clear our drains'. Oh really? Being unable to alter the lie of our land, which is uphill of his so where would drains drain, we fenced off the offending corner and planted it up with Willow, Aspen and a mixed bag of native trees and shrubs to use up the water from a small spring in our field. From our side it's worked perfectly as the trees have grown; from his side, well he's stopped moaning and his corner is no wetter than it has been for the past 30 years
