What is Composting?
Composting is a simple technique that turns organic materials, like yard debris and vegetative food scraps, into a rich soil conditioner that we can use in our yards and gardens
This process occurs in nature continually as vegetation falls to the ground and slowly decays. Composting is simply a technique we can use to accelerate this natural process.
Why Compost?
- Reduces the amount of garbage to be landfilled or incinerated
- Provides an excellent soil conditioner
- Enhances a natural cycle of our environment
- Is easy to do and makes sense
Four Easy Steps to Backyard Composting
Step 1: Choose and Prepare a Site:
The ideal location for a compost pile is a spot that receives equal amounts of sunshine and shade. There are many simple and inexpensive ways to prepare a site. Here are just a few ideas:
- Place compostable materials in a dense pile
- Use chicken wire and wooden stakes to build an enclosure
- Scrap lumber can be used to build wooden bins
- A variety of compost bin ideas and plans from the simple to the sophisticated is available. Call or email our office for brochures.
Step 2: Select and Combine and Right Materials
Much of the yard debris and vegetative food scraps many of us place in the garbage are easily composted. The main parts of a compost pile are:
- grass clippings, seedless weeds
- green vegetation
- dry layers of leaves, chipped twigs and branches
- garden soil and/or manure
What to Compost
Choose the right materials to keep your compost productive and free of odors and pests.
Compost | Do Not Compost |
---|---|
grass clippings | meat and fish |
leaves | chicken/poultry |
vegetable scraps | animal fats |
fruit peelings/cores | bones |
egg and nut shells | vegetable oils |
garden clippings | dairy products |
stalks and stems | plastics |
seedless weeds | synthetic fibers |
wood ashes |
Step 3: Keep Moist and Provide Ventilation
Water should be added periodically to maintain a sufficient moisture content. The pile should not be soaked, but watered to the consistency of a wrung-out sponge
Air circulation aids in the composting process. How frequently you turn your compost pile by moving materials from the bottom to the top will determine how soon your compost will be ready for use.
Air circulation aids in the composting process. How frequently you turn your compost pile by moving materials from the bottom to the top will determine how soon your compost will be ready for use.
- Infrequent turning (once every 4-5 weeks) produces a finished compost in 4-6 months. With more frequent turning (every 3-5 days), compost can be ready in 2-3 weeks.
- You can also help to produce good airflow by pushing rods or poles through your compost pile to produce airways.
Step 4: Use the Compost In Your Yard or Garden
Reap the benefits of your labor by using the composted material as a soil conditioner for landscaping or in your garden!
- The compost is ready for use when it is a rich dark color and it is broken down into small particles.
- It is good practice to sieve the compost through a 1-1/2″ screen. Return the coarse, unfinished material back into your pile for further decomposition.
- Apply the compost to your garden in 1″ to 3″ layers. Mix the compost and soil well and work it into the ground. It is best to add no more than one pound of compost per square foot of soil.
