Introduction

Tumbling composters help you create nutrient-rich compost for your garden by continuously mixing and aerating the organic materials inside. As a result, they speed up the decomposition process, allowing you to achieve finished compost in a matter of weeks instead of months. In this article, we’ll explore three ways to build your own tumbling composter using readily available materials.

1. DIY Barrel Tumbling Composter

Materials:

– A 55-gallon plastic drum or barrel with a tight-fitting lid

– Heavy-duty metal hinges

– Screws and nuts

– Drilling machine and drill bits

– Metal pipes or wood for the supporting frame

Steps:

1. Drill several 0.5-inch holes throughout the barrel to provide proper aeration.

2. Attach the metal hinges to one side of the barrel’s lid, attaching it securely with screws and nuts.

3. Construct a sturdy frame using metal pipes or wood to support the barrel’s rotation mechanism.

4. Install brackets on each side of the frame where the barrel will sit horizontally.

5. Place the barrel on the brackets and secure it with an axle through its center.

6. Fill your new tumbling composter with green (nitrogen-rich) and brown (carbon-rich) materials, close the lid, and rotate it regularly.

2. Tire Stack Tumbling Composter

Materials:

– 4 to 6 discarded tires

– Waterproof tarp or plywood sheet

– Bungee cords or straps

– Drill or awl for puncturing holes

Steps:

1. Punch drainage holes across a waterproof tarp or cut a piece of plywood with enough diameter to cover the bottom tire.

2. Stack at least four tires on top of each other, ensuring they line up properly.

3. Cover the openings at either end with a tarp or plywood sheet and secure in place with bungee cords or straps.

4. Fill the tire stack with green and brown materials, close the opening, and secure it.

5. To “tumble” the composter, undo the straps and disassemble the tire stack.

6. Re-stack the tires in a different sequence to provide thorough mixing of materials.

3. Rotating Mesh Composter

Materials:

– 1 large wire mesh roll (lawn fencing or chicken wire)

– Wooden dowels or metal pipes

– Twine or zip ties

– Thin sheet of plywood for a base

Steps:

1. Create a cylindrical shape by connecting both ends of the mesh roll using twine or zip ties.

2. Drill two holes at equal heights on opposite sides of the cylinder, approximately 12 inches from either end (a total of 4 holes).

3. Insert wooden dowels or metal pipes through each pair of holes to serve as axles for rotation.

4. Attach a base made from a thin plywood sheet to one end of the cylinder with screws or twine.

5. Place your new mesh composter on a stand or on trestles, ensuring that the axles can rotate freely.

6. Fill it with green and brown materials, tumble regularly by rotating the cylinder around its axles.

Conclusion

With these three DIY tumbling composter designs, you can easily create nutrient-rich compost that will greatly benefit your garden’s plants and growth. Choose whichever method suits your space and resources best, and start enjoying faster composting times today!
