Step by Step How-To for Composting

Composting is an excellent way to recycle organic waste, enrich soil, and reduce the need for chemical fertilizers. Here’s a step-by-step guide on how to start composting:

1. Choose a Compost Bin:

  • Type: You can choose from a composting heap, wooden crate, plastic bin, tumbler, or worm bin (vermicomposting). The choice depends on your space, budget, and preference.
  • Location: Place the bin in a dry, shaded spot with good drainage. It should be easily accessible year-round.

2. Collect Green and Brown Waste:

  • Green Waste (Nitrogen-rich): Vegetable scraps, fruit peels, fresh grass clippings, green leaves, coffee grounds, tea bags, and manure.
  • Brown Waste (Carbon-rich): Dry leaves, twigs, cardboard, paper, straw, hay, and wood chips.

3. Start Your Compost Pile:

  • Begin with a 6-inch layer of coarse, dry materials like twigs at the bottom for good aeration.
  • Alternate between layers of green and brown waste. Ideally, maintain a ratio of 2 parts brown waste to 1 part green waste.
  • Make sure to chop or shred larger materials to speed up the decomposition process.

4. Maintain the Pile:

  • Moisture: The pile should be damp like a wrung-out sponge. If it’s too dry, sprinkle some water. If too wet, add brown materials to absorb excess moisture.
  • Aeration: Turn the compost once a week using a garden fork or shovel. This introduces air, speeds up decomposition, and prevents the pile from smelling bad. Tumbler bins can be rotated.
  • Size: A compost pile should be at least 3 feet high and 3 feet in diameter to retain heat and decompose efficiently.

5. Monitor Temperature:

  • A compost pile will heat up due to microbial activity. Warmth indicates active decomposition.
  • If the pile cools down, it might need more green materials, moisture, or aeration.

6. Optional Additives:

  • Compost Activators: These contain nitrogen and can kick-start the composting process. Examples include manure, grass clippings, or commercial activators.
  • Worms: In worm bins, red worms (or “red wigglers”) help break down organic materials.

7. Harvesting the Compost:

  • In 2-6 months, depending on conditions and maintenance, the bottom of the pile will turn into a dark, crumbly, soil-like substance. This is mature compost.
  • Harvest the finished compost and leave unfinished materials in the bin to continue decomposing.

8. Use Your Compost:

  • Mix compost into garden beds or sprinkle it on top as mulch.
  • Use it as a potting mix component (usually up to 1/3 of the total mix).
  • Make “compost tea” by soaking compost in water and using the liquid as a nutrient-rich plant feed.

9. Common Issues:

  • Bad Odor: Caused by too much moisture or green materials. Add brown materials and turn the pile.
  • Flies or Pests: Ensure you aren’t adding meat, dairy, or oily foods. Cover the compost with a thick layer of brown materials or soil.
  • Slow Decomposition: The pile may be too dry or lacking green materials. Moisturize and add green waste.

10. Maintain Good Practices:

  • Don’t add meat, dairy, diseased plants, or inorganic materials.
  • If you’re concerned about weed seeds, ensure the pile reaches a high enough temperature (around 140°F or 60°C) to kill them.
  • Wash your hands after handling compost.

Remember, composting is as much an art as a science. You might need to adjust based on your specific conditions, but with time and experience, you’ll develop a feel for what your compost pile needs.
