Imagine a composting system so simple that it works while you sleep, requires zero maintenance, and keeps your garden worms working overtime. Enter the DIY Worm Tower, the ultimate solution for in-ground composting that feeds your plants and reduces kitchen waste—all while giving your worms a cozy home. Let’s build one!
What Is a Worm Tower?
A worm tower is essentially a mini worm bin installed directly in your garden soil. Worms live in the tower, feast on your kitchen scraps, and distribute their nutrient-rich castings into the surrounding soil. It’s composting on autopilot—and your plants will love you for it.

Why Build a Worm Tower?
- Convenience: No need to harvest compost or worry about smelly piles.
- Eco-Friendly: Compost directly where it’s needed.
- Low Maintenance: Just add food scraps and let the worms do their thing.
Materials You’ll Need
Before you start building, gather these materials:
- A large PVC pipe or similar tube (6-8 inches in diameter, 2-3 feet long).
- A drill (to make holes).
- Compostable bedding materials (e.g., shredded newspaper or coconut coir).
- A saw (to cut the pipe if needed).
- A small lid (to keep critters out).
- Worms! (Red wigglers work best—get them here).

Pro Tip:
You can also use old buckets, barrels, or other upcycled containers. The worms won’t mind as long as it’s dark and cozy.
Step-by-Step Guide to Building a DIY Worm Tower
Step 1: Prep the Pipe
Cut your PVC pipe or chosen container to the desired length (2-3 feet). This will be your tower.
Step 2: Drill Holes
Using your drill, make holes along the bottom two-thirds of the pipe. These holes allow worms to travel between the tower and your garden soil. Aim for 1/4-inch holes spaced a few inches apart.
Step 3: Choose a Location
Find a sunny spot in your garden bed or near plants that need a nutrient boost. Dig a hole deep enough to bury the bottom two-thirds of the tower.
Step 4: Add Bedding
Fill the bottom of the tower with a few inches of moist bedding material. Shredded newspaper, cardboard, or coconut coir works well. This creates a comfortable environment for your worms.
Step 5: Introduce Your Worms
Gently add your red wigglers to the tower. They’ll settle in and start exploring.
Step 6: Add Food Scraps
Place a small amount of chopped fruit and veggie scraps into the tower. Cover the scraps with more bedding to reduce odors and deter pests.
Step 7: Cover It Up
Cap the tower with a lid to keep out rain and critters. An old flowerpot or DIY wooden lid works well.

Maintaining Your Worm Tower
- Feeding: Add food scraps once a week, or as often as the worms can eat them.
- Moisture: Check occasionally to ensure the bedding stays damp but not waterlogged.
- Rotation: Move the tower to another garden spot every 6-12 months for even soil enrichment.
Benefits of a Worm Tower
- Direct Soil Improvement: Worm castings are distributed naturally into the surrounding soil.
- Pest Control: Keeps scraps underground, away from flies and rodents.
- Water Retention: Enhances soil structure and moisture retention around plants.
FAQs About Worm Towers
Q: Can I use a worm tower in a raised bed?
Absolutely! Worm towers are great for raised beds and smaller gardens.
Q: Do I need to empty the tower?
Nope! Worm towers are self-sustaining. The worms do all the work.
Q: What happens in winter?
Worms will slow down in colder weather, but the system can still function as long as the ground isn’t frozen.
