Composting and Yard Care


About Composting

Each year, nearly four million tons of yard trimmings in the form of leaves, grass, tree limbs, weeds and other organic debris are thrown away in Texas. That amounts to almost 20 percent of all trash in municipal landfills. 

In addition, Texans spend more than $300 million each year disposing of yard trimmings, and billions in total yard care costs, including water, fertilizer, and chemicals to combat harmful insects and plant diseases. Costly synthetic fertilizers and pesticides allow chemicals to wash into lakes, streams, and underground water.

Composting is a simple biological process that breaks down leaves, grass clippings, wood chips, brush, and food scraps into a dark, crumbly, nutrient-rich, organic product. It's nature's way of recycling organic matter and returning it to the earth so that it may be used again.

You should however avoid composting meat, dairy products, cooking oil and grease.

Creating Compost Piles

A compost pile may be started directly on the ground using a container or structure, which will save space, hasten decomposition and keep the yard looking neat.

  1. Select a level area near a water source that receives equal amounts of sunlight and shade during the day.
  2. Apply a 3- to 6-inch layer of chopped brush, branches, dead leaves, straw and twigs to allow air circulation around the base of the heap.
  3. Add 6 inches of grass clippings, manure and sawdust. Materials should be kept damp, but not wet and soggy. Rabbit pellets, cow or horse manure only.
  4. Repeat Steps 2 and 3 until the pile is sufficient in height. The ideal pile is 4- to 5-feet wide and high.
  5. Every couple of weeks, turn the pile and water it until damp. Turning the pile more often makes compost faster.

Indications of a Finished Compost Pile

Compost is ready when:

  • It is crumbly and not identifiable as grass, leaves, etc.
  • It looks like dark soil.
  • It no longer heats up after it is turned or wetted.
  • It smells earthy, not sour, putrid or like ammonia.

A properly made heap will reach temperatures up to 160º F in several days. During this time, there will be settlement in the pile. This is a good sign that the compost pile is working properly.

Composting Process

The composting process may last from a few weeks to months, depending upon the types of materials used, water requirements, and how often the pile is turned. Apply the finished product to gardens or around trees and shrubs by turning the soil and applying 1- to 3-inch layers of compost, working it in well.
