Buying Guide

At first sight, it might look not so easy to decide on a compost tumbler that suits your garden size and expectations most. However, you should consider first what exactly you require when making your own compost.

Garden Size

First, your garden and yard size is important to determine the ideal volume and size you require for your composter. You need sufficient space to place the tumbler without standing in everybody’s way. Also, consider how much compost you need regularly.

Type of Composter

If you need to fertilize your garden or vegetable beds regularly, then a dual compartment composter will be the ideal choice for you. You always have a supply of readily fermented compost at hand, while in the second chamber, a new batch is decomposing already. Keep in mind that making compost takes around 4 – 6 weeks on average. Please avoid filling in high-protein food scraps like meat or fish, as these are not suitable to be composted.

Durability

As usual, the quality and durability of the materials used to construct the compost tumbler are important too. The composter shall last you for a long time; hence the materials must withstand the elements and the wear and tear. You also want to rotate and turn the compost chamber without big efforts.

Oxygen and Accessories

The aeration is another point to pay attention to. Without oxygen, there is no decomposing process. The same is for the heat absorption of the compost chamber, as heat is needed as well for the process.  However, the compost chamber must be closed tightly to keep rodents out of your garden and house. Further accessories like wheels to pull the compost tumbler conveniently within your garden or an extra garden cart are welcome features too. So are integrated mixing bars for even curing of the compost. And last but not least, the composter’s assembling should not be too complicated; most of them are not pre-assembled upon delivery.

We hope our recommendations will help you find the most suitable compost tumbler for your garden.
