Our Comprehensive Buying Guide

 

Compost tumblers save you the trouble of trying to break down various scraps and clippings into compost by easily mixing them together and turning them into high-quality fertilizer. Whether you are looking for a cheap compost tumbler or a more expensive one, there are certain aspects you should consider before making a purchase.

Our guide will help you learn more about the particularities of compost tumblers and what are some of the most important things to keep in mind when looking for this type of product.

Size and capacity

A compost bin tumbler looks similar to a tombola spinner because everything that you put inside it is mixed and turned into compost, without you having to mix it manually or use a shovel. Compost tumblers have various sizes and capacities, and choosing the right one for your needs will not only make it easier to use but also more effective.

A small compost tumbler would be more convenient for beginners and one or two people households because they produce less waste that can be easily turned into compost by a 35-gallon tumbler. Plus, if you intend to place it on your balcony or simply don’t have too much yard space, a compact compost tumbler can save you a lot of headaches.

On the other hand, those who want to dispose of large quantities of scraps and clippings need a large compost tumbler that can hold at least 40 gallons of waste. Depending on how much compost you want to make, you can also go for a dual chamber compost tumbler that allows you to constantly add new scraps so that the composting process is uninterrupted.

 

Design and features

Many compost tumblers mix the compost thanks to a central axis that spins, which is why you need to roll them by hand, while others have a handle that you can spin, and this is how the compost barrel tumbler is spun. A tumbler needs to be easy to turn, otherwise, you won’t be able to repeat this process every couple of days, and you won’t get compost.

A two compost bins tumbler can be a good choice if you want to enjoy a continuous composting flow. If you want to keep it simple and have smaller quantities of waste, simple and affordable compost tumblers are enough. You can also choose a tumbler that can make not only regular compost but also liquid fertilizer, thanks to a tea maker base where all the liquid is collected.

Air vents are another important feature because good airflow is essential for great compost. Plus, a user-friendly design means that it’s easy to open and close the tumbler bin.

Materials and durability

Keep in mind that large compost tumblers, like the Miracle Gro compost tumbler, also need to have a sturdy structure in order to be stable and long-lasting. Plus, they need to be made of high-quality materials.

A good tumbler compost bin is made of non-toxic, BPA-free plastic that is also resistant to UV radiation. The frame is also important for durability, and stainless steel that is corrosion-resistant would be the best choice. It’s preferable to keep your tumbler outside because natural heat is a very important factor in composting. Remember that most compost tumblers require assembly.

 

 

Frequently Asked Questions: 

 

Q: How to use a compost tumbler?

Those who are new to composting are probably wondering “what is a compost tumbler anyway?” and the simple answer is that it’s a barrel that can be rotated or turned, that can be filled with scraps which are then mixed inside of it until they turn to compost.

For those who are used to composing on their own, using a compost tumbler will make things much easier. If you want to know how to compost in a tumbler, there are a few easy steps.

First, you need to fill your tumbler with kitchen scraps and yard waste, making sure that you are adding enough green and brown material. In order to speed up the decomposition, you need to turn the tumbler a few times every couple of days. This will make sure everything is mixed well. If there is also enough heat, you will get fresh compost in a few weeks.

Q: How do you use a dual compost tumbler?

If you are wondering how to make compost in a tumbler with two chambers, know that it’s not a complicated process. In order to have a continuous composting flow, you need to add fresh scraps into one of the chambers on a regular basis, while the other one is cooking. This way, when the first batch of fresh compost is done, the other one is already cooking.

The main advantage is that you don’t have to throw away any waste because you can continuously add it to the tumbler. The downside is that, when both bins are almost full, it can be harder to rotate the tumbler, and the composting process is slowed down. It can also be more difficult to empty out the barrel.

Try to collect enough waste to fill your compost tumbler. This helps everything to decompose evenly for faster results and rich compost. If you want the composting process to start faster, add an accelerator, which will introduce bacteria that kickstarts the decomposition. Next, all you have to do is follow the instructions and turn the tumbler a few times every couple of days.

Adding enough green and brown material is the first step, but air circulation and heat control are also important.
