Layer mulching in the subtropics and tropics

Layer mulching was developed in the sub-tropics and is extremely useful for making 'compost' right where you're going to establish a garden. You place various materials (see below) in layers, although the method of applying the mulch layers is the reverse of that used in building the compost pile, where the heaviest material is on the bottom.

With layer mulching you need the lightest material available for the speediest breakdown. This happens when a concentration of micro-organisms, bacteria, and earthworms are attracted to the soil's surface. These minute creatures will move upwards into the second layer of material after ingesting the first layer.

Of course, the easiest way to apply mulch is on unplanted soil. However, if you're converting an orchard or plantation to enjoy the numerous advantages of layer mulching, obviously you must mulch around the existing plants. When you do this be especially careful to maintain a clearance of about ten cm from tree trunks to allow air to circulate.
