In gardening, many lessons can be drawn from observing nature.
In nature there is no bare ground exposed to the sun, winds and rain, except for the deserts.
Each space is immediately colonized by plants with the result that the soil will be protected from the erosive action of the elements.
Even in the garden we should avoid to keep the ground uncovered.
A soil covered with ground covers or mulching will retain its structure, will maintain moisture for longer a period and will be the ideal habitat for terrestrial animals and beneficial micro-organisms.
