Mulch is a substance that you spread on the ground around trees, shrubberies, and other plants to keep the soil moist and cool, to inhibit weed growth, and to make a garden look attractive. There are numerous organic options that will eventually biodegrade and nourish the soil. To help you choose the right one for your purposes, The Gardener, an experienced landscaping contractor in Columbia, MO, discusses some of the most common types in the following sections.

A Quick Guide to Organic Mulch

1. Wood Chips

Wood chips are the most common organic mulch. They are particularly attractive and effective, though they sometimes cost more than other options. However, if you chip your own wood, that cost is eliminated.

2. Wheat Straw

Straw makes an effective ground covering and does a stellar job of preventing weeds and keeping the soil moist. Moreover, although it has little phosphorus content, it does deliver moderate amounts of nitrogen and potassium, two nutrients that nourish soil and greenery.

3. Grass Clippings

Grass clippings, which are a good source of nitrogen, are not just cheap, but absolutely free. If you gather them as you mow the lawn and spread them around your trees and shrubs, you'll help nourish the soil and protect the moisture around the root ball of your plants. Their only weakness is a tendency to be blown around by the wind.

4. Leaves

Fallen and raked leaves are likewise free. Their only cost is a bit of light yard work on your part. You can even use the "mulching" feature on your lawn mower to chop them into pieces. This helps them decompose faster to enrich the soil.

5. Cardboard & Newspaper

Cardboard and newspaper are both exceptional weed barriers, but they may not look as natural or attractive as some of the other types. Cost is minimal. Most people have boxes lying around either from a prior move or from products they've purchased in the past, while newspaper tends to accumulate in large quantities.
