If you’ve only recently decided to add the composting process to your garden routine, a quick search of the available options can be a little overwhelming. That’s why we’ve compiled a buying guide to help you identify the features required to make composting easier. We recommend reading our guide to get an idea of the features to consider as you start shortlisting favorites.
If you’ve decided to add compost to your garden, the next question in your mind will center around the best method to process the compost. While you can do it manually in a corner in your yard, it’s considerably easier to use a compost tumbler. Some of the reasons you’ll benefit from using a compost tumbler include:
There are many items that you can place in a composter to eventually add to your garden. Making compost out of your kitchen scraps and garden cuttings will considerably reduce the waste you send to the landfill. Some popular items to add to your composter include:
While the general principle of compost tumbling is the same, not all tumblers work the same. There’s also a difference in the material used to construct them, capacity, size, and the number of chambers. It’s important to know which features would suit your individual gardening needs. Are some features better than others? Are there specific features that you should highlight in your shortlisting process? Keep reading to get an idea of the key specifications to consider.
When you’re considering capacity, it’s crucial to first establish your composting needs. If you want to add compost to a thriving vegetable patch, you might need a larger tumbler. For a smaller garden, a regular size composter would work fine. Generally, the smallest composters hold about 15 gallons, while larger units can hold as much as 80 gallons. It takes about ten weeks to completely process a batch of compost.
This leads some avid gardeners to invest in composters with dual chambers, which allow composting to take place at different rates. The Barton Tumbler Composter has a capacity of 37-gallons and has two chambers. The Spin Bin Outdoor Compost Tumbler, on the other hand, has a larger capacity but only one chamber. For a much smaller tumbler, the Dual Chamber Compost Tumbler by Miracle-Gro has 18.5 gallons with two chambers.
For durability, it’s important to consider the material your potential tumbler is made of. Some models are constructed using steel, by most compost tumblers are typically made of a UV-protected plastic bin that rests on a tubular steel frame.
Plastic is ideal because it’s weather and corrosion-resistant. Opting for a plastic bin will allow heat to transfer slowly and won’t rust from the moisture or outdoor elements. Steel frames make it easier to hold the weight of the tumbler as it fills up.
On our list of favorites, the IM4000 Dual Chamber Tumbling Composter and the Lifetime 60309 Outdoor Rotating Composter are only two examples of plastic tumblers. The Jora Composter JK 270, on the other hand, is made of galvanized steel. Other models like the IM4000 Dual Chamber Tumbling Composter are made from 100% post-consumer recycled polypropylene.
When it comes to rotation, you want to consider a tumbler that’s going to be easy to use. Some tumblers feature handles for turning the barrel to mix the compost. Other types of compost tumblers have rotation locks to have the two parts close securely when you rotate the barrel up and down.
Pro tip: opt for the system that’s going to be easiest for you to use when it’s full of compost. Would you prefer to crank a handle or roll a barrel? Since compost needs to be continuously mixed, you’ll have to move the barrel around, and this includes when it’s full.
Our list features the Barton Tumbler Composter, which features a rotating barrel best for small quantities of compost. The RSI MCT-MC Maze Compost Tumbler has a handle that makes it easy to mix the decomposing material.
Since the tumbler needs to stand in the sun for the composting process to work effectively, extended exposure to the weather elements could cause wear on the materials. That being said, it’s recommended that you opt for a tumbler that’s made of UV-protected materials. In most instances, this means looking for galvanized steel or high-density polyethylene plastic. The Lifetime 60076 Compost Tumbler on our list is made from this type of plastic and is guaranteed to be UV-protected. The Jora Composter JK 270 is made from galvanized steel if you’re not a fan of plastic.
The size of compost tumbler you should look for depends on the space you have available to put it. If your composter is going to be in the way, it’s just going to annoy you, and you’ll end up not using it at all. Ideally, your composter should be out of the way but still in a place where it receives maximum sun. Always consider the space you want to dedicate to it before randomly choosing a potential favorite.
Our review list features the FCMP Outdoor HOTFROG Rolling Composter with dimensions of 24” x 27” x 24”. For larger spaces, consider the Lifetime 60309 Outdoor Rotating Composter with dimensions of 65” x 31” x 43.3”.
Some additional features to keep an eye out for include:
Dual-chamber designs: A composter with two compartments allows you to get a new batch started while the existing batch is decomposing. The Jora Composter JK 270 and the Dual Chamber Compost Tumbler by Miracle-Gro are examples of dual-chamber designs.
Opening size: If you’re planning to place large quantities of leaves or clippings into your composter, you’ll need a model with large opening size. In this instance, you could consider the Lifetime 60076 Compost Tumbler, which boasts an extra-large removable lid.
Accessories: Additional accessories that form part of the package can sometimes make using the particular composter so much easier. For instance, the RSI MCT-MC Maze Compost Tumbler comes with an additional cart. The cart easily fits under the tumbler and makes it considerably easier to move compost from the tumbler to the garden. This typically means there’s no need to invest in a wheelbarrow or separate bucket to move the compost around. Always look for accessories that make the composting process easier!
Your compost is ready for use once it’s dark and crumbly. You can use compost around your garden or vegetable patch.
