Best Compost Tumbler – Here’s What You Need to Know

How to Choose the Best Compost Tumbler

Each brand and model of compost tumbler has different features, capacities, and requirements. Finding the best compost tumbler to fit your needs can be a challenge. Ask yourself these four main questions to help narrow down your decision: 

  • What do I want to compost?
  • Where will I keep my composter?
  • What will I do with the finished compost?
  • How much time do I want to spend composting?  

First, think about what kind of material you plan to compost. Do you need a composter just for kitchen scraps? Would you want to compost yard waste too? 

Some compost tumblers are designed for kitchen waste alone and have smaller capacities. Larger capacity tumblers are more suitable if you plan to compost yard waste along with your kitchen scraps. 

Next, take a moment to think about where you will keep your composter. Do you plan to keep it inside your home or garage? Will you put it in the garden or on the patio? 

Keeping an indoor composter has several advantages. Indoor compost bins are convenient and easy to access. Because you can keep them in any dry, dark area, they do well in basements, closets, or cabinets. Keeping compost bins indoors also allows you to use them all year long without worrying about temperature changes. 

Outdoor compost bins are excellent options if you want to compost your yard waste as well. Keep in mind that you need to shield outdoor composting bins from the weather and heavy rain. They should be kept out of direct sunlight in the summer and insulated to prevent freezing in the winter.  

Another thing to think about is what you want to do with your finished compost. From brewing compost tea to making your own DIY potting soil, finished compost has many practical applications. Will you use it for fertilizing your garden? Will you keep it for houseplants? Were you only composting to reduce your waste and don’t have any specific plans for it?

If you need large amounts of compost for gardening, picking a higher capacity model with a strong seal to hold in heat is a wise choice. With larger, heat-sealing compost tumblers you can quickly make enough nutrient-rich soil to keep your garden vegetables healthy and thriving. 

Smaller compost tumblers will allow you to make enough compost to give your houseplants a nutrient boost. They also can help you to reduce your overall household waste. Even if you just plan on scattering the finished compost outside, small compost bins can help you reduce your carbon footprint

Finally, think about how often you will fill up your compost tumbler. Do you have a lot of organic material to compost at one time? Do you have daily kitchen scraps that you need to add to your compost tumbler continuously? 

Single chambered compost tumblers work well if you plan to fill up the container and wait for the compost to finish before adding more. Dual chambered compost tumblers are smart options for people that want a steady stream of compost. You can fill up one chamber, and while you are waiting for that compost to finish, keep adding scraps to the second chamber.

Now that you’ve had a chance to think about what kind of composter will best fit your needs, check out our recommendations for the five best compost tumblers on the market.

FAQ

Are compost tumblers worth it?

In short—absolutely. Most compost tumblers require very little attention and effort, unlike traditional outdoor compost piles or even indoor worm bins. Simply add your kitchen scraps or yard waste, and remember to turn the composter as directed in the instruction manual. 

Compost tumblers not only transform organic waste into a plant and garden superfood but can also help you reduce your carbon footprint. In our book, that makes the little effort they require totally worth it. 

How often should I turn my compost tumbler?

On average, you can expect to have to rotate your tumbler 2-3 times per week. 

However, each brand and model has different recommendations for how much you should turn the composter. Make sure you check your compost tumbler’s instruction manual for the proper guidelines. 

What should you not put in a compost tumbler?

While composting can work wonders for many organic materials, there are some things you should avoid putting in your compost tumbler. These include:

  • Meat
  • Bones
  • Dairy products
  • Oils or grease
  • Citrus
  • Bread or cooked grains
  • Treated wood
  • Glossy papers

All of these things can either interfere with the composting process or are unable to be properly broken down. Save your composter, and look into other sustainable disposal methods for these items.  

How do you make a good compost tumbler?

Making a compost tumbler that is cost-effective, efficient, and eco-friendly is probably easier than you think. 

There are many different styles you can make in just an afternoon. Most require only a sealable container, some treated wood, wheels, hinges, and basic tools. 

You can make our favorite DIY tumbling composter by using a 5-gallon barrel

The first step is to cut a hole in the side of the barrel for a door. Then, reattach the cutout with hinges and pin locks, so it opens and closes easily. Drill half-inch holes into the sides to keep your compost aerated. 

You can create a platform by attaching four wheels to a treated wood board. Place the barrel on top of the wheels and give it a spin!


Our Verdict

Using a tumbling composter makes composting quicker and easier than traditional methods. From heavy-duty composters like the FCMP IM4000 Dual Chamber Tumbling Composter to space-saving compost bins like Miracle-Gro’s Small Composter, there are many different models available to suit your needs.
