One of the most important part of gardening is mulching. It keeps down weeds by blocking the light that allows weeds to germinate. Mulch will slow down the evaporation of moisture from the soil, which also will keep the soil from drying out and creating a crusty soil.

  Earthworms love organic mulch, they eat the organic matter and produce castings. When they move around in the soil the tunnels they make aerates the soil and improves the texture. Other organisms do the same. All the work they do makes a nutrient-rich substance that our plants need.

  This process is actually decomposition, which adds valuable organic humus to the soil.

  Simple steps to mulching:

  1. Distribute the mulch material to a depth of at least 3 to 5 inches. The more coarse the material, the more you add.

  2. Place the mulch between and around the plants, but allow the immediate area around the base of the stems of annuals and perennials to be free of it.

  3. Moisten the mulch.

  When mulching trees and shrubs, keep the mulch approximately 5 - 10 inches from the base of the tree. Over time mulch on trunks, even with organic matter too close to the trunk of the plant, will cause many problems down the road.

  The wood mulch keeps the soil cool and maintains an even soil temperature. If bark chips and sawdust are used they may delete nitrogen from the soil when they decompose, so add some nitrogen to the soil first before and then after laying down such mulches.

  Look at organic wastes like shredded tree barks or light pruning, seasoned sawdust, wood shavings, peanut shells, cocoa bean hulls, rice husks, ground corn cobs, grass clippings, unused vegetable waste and seaweed.

  Black Plastic Sheets

  If organic methods are not your style then take a look at black plastic sheets that are used for mulching the soil. It affords excellent weed control and moisture conservation, if done properly.
