What Is Worm Composting and Why Should You Try It?
Before we dive into the bins, let’s quickly cover what worm composting is. Worm composting, or vermicomposting, is a process where worms (usually red wigglers) break down organic waste like kitchen scraps, turning it into rich, dark compost called “worm castings.” These castings are like gold for your garden—they’re packed with nutrients that help plants grow strong and healthy.
Here are a few reasons why you should give worm composting a try:
- Eco-Friendly: It reduces the amount of waste going to landfills.
- Cost-Effective: You can make your own compost for free instead of buying it.
- Great for Gardens: Worm castings improve soil structure and fertility.
- Fun for the Family: Kids love watching worms do their magic!
Now, let’s get to the good stuff—how to make your own worm composting bin.
1. The Easiest Worm Bin Ever: A Simple Plastic Bin Setup
If you’re new to worm composting, this is the perfect place to start. The easiest worm bin ever is made from a simple plastic storage bin. It’s quick to set up, requires minimal materials, and works great for small spaces.
Materials Needed:
- 1 large plastic storage bin with a lid (18-20 gallons)
- A drill with a 1/4-inch bit
- Newspaper or cardboard
- A handful of soil
- Red wiggler worms (you can buy them online or from a local garden center)
Step-by-Step Instructions:
- Drill Holes: Drill small holes around the top of the bin for ventilation and a few at the bottom for drainage.
- Prepare Bedding: Shred newspaper or cardboard and soak it in water. Squeeze out the excess water and fluff it up in the bin.
- Add Soil and Worms: Mix in a handful of soil to introduce beneficial microbes, then add your worms.
- Feed Your Worms: Start with small amounts of kitchen scraps like fruit and veggie peels. Avoid meat, dairy, and oily foods.
