All this seems very logical until someone asks the seemingly daft question 'but why dig at all?' Think about it: untold billions of acres of land have never been touched by a spade but are populated by a profusely growing collection of trees, shrubs, herbaceous plants and annuals. So why do we spend so much time breaking our backs under the impression that our way produces better results than nature? The answer to this conundrum lies in the simple fact that we walk on the soil, compacting the crumb structure and excluding air. Plants respire - a process which involves roots converting sugars into growth energy and one of the raw materials necessary for this to take place is the oxygen our size nines have squeezed out.
By using a deep bed system we are working with nature, enabling natural soil inhabitants, of which there are millions per cubic foot, to beaver away at doing what they do best - breaking down organic material. Picture the scene: a leaf falls from the tree and a nearby worm, leaning on his mini Spear & Jackson stainless steel spade, wipes the sweat off his brow, grabs the stalk and starts dragging it into the cave he's just excavated. Easy, isn't it. Out with the deckchair.
