Making a compost box is very simple, requires little materials, and is great for the environment.
Step 1: Making the box
The box should be 2-4-8. Keep in mind that your box has no top. You can make your box out of one 4-8 piece of wood, two 2-4 pieces of wood, and two 2-8 pieces of wood.
NOTE: you can make your boxes different sizes, just use scale factors for the dirt, worms, ect.
Step 2: Starting the box
The two basic elements that make up compost are green garden debris (grass clippings or old annuals) and brown garden debris (dry leaves). Green ingredients are high in nitrogen and brown materials are high in carbon. All these items are required for a successful box. Use one part green to two part brown materials break down fastest.
Step 3: Adding the dirt
Add in about 2 shovelfuls of garden soil to help the the microbial activity in your pile.
Step 4: Adding worms(this step is optional)
Although this is not required, it helps to decompose. A 2-4-8 box should have about 500(you can use more for better results) worms.
