If the grass seems greener on the other side of the fence, it might be because your neighbors are composting. Compost is an easy, low-cost way to improve your soil for a happier lawn and a more productive garden. Not only does composting create rich, healthy soil, it also keeps kitchen scraps and yard waste out of landfills. Whether you’ve been composting for a while or are just getting started, it can be hard to know which composter will be the best choice for your needs. We’ve put together the ultimate guide to composting and selecting the best composter to take the all the guesswork out of it for you.

Composting 101

If you’re new to composting, you may be wondering what it does and how to do it. Stu Cambell, author of the definitive composting book “Let it Rot!” describes composting as simply speeding up a natural process. The process really is that simple. You take organic material like food scraps, lawn waste, egg shells, and hair and put it together so it can decompose. This process creates a nutrient rich soil additive known as compost. To accomplish this, you simply need a composter or container, organic material, and some time for the material to break down. Heat and moisture help the speed up the process, and insects like worms can also contribute.

Numerous items can be composted. The Environmental Protection Agency indicates that 20 to 30 percent of materials we send to landfills every year are compostable. To ensure your compost breaks down in a timely fashion and has all the essential nutrients that plants need, you need to make sure your compost includes a mix of green or fresh matter and brown or older materials. These items add nitrogen, carbon, and other beneficial nutrients to the compost. Some examples of items you can compost include:

Green Materials:

• Fresh lawn clippings
• Vegetable and fruit scraps
• Flowers
• Food items (not meat or fish)
• Garden waste
• Manure

Brown Materials:

• Dead leaves
• Coffee grounds and paper filters
• Shredded cardboard and paper
• Broken down twigs, wood shavings, and sawdust
• Peanut shells
• Straw

Other Materials:

• Egg shells
• Hair
• Wool or cotton fabric or lint

Types of Composters

Composters come in many different styles, sizes, and can offer a number of various features. Even with all that variety, composters can be broken down into three primary types. Each type works in a different way to create compost.

Classic Bin Composters

Composting-Bin

This traditional style of composter is reminiscent of the old compost pile, but with several added benefits. These bins can come in a variety of materials and designs, but the basic principle is the same. You continue to add material to these creating layers of matter. The lower, older layers will turn to compost first, so you will need to be able to access the bottom of the container.

The advantages to bin composters are they require very little upkeep or involvement in the process. They are ideal for long-term compost projects like gardens and work well for anyone who wants to add material continuously.

The disadvantage of this style is it can take several months to produce compost. The process can be sped up if the compost is routinely aerated or broken up, but this requires more effort.

Tumbler Composters

Compost-tumbler

This type of composter does exactly what its title suggests; it tumbles the compost in a rotating bin. You add a batch of compostable material to the bin and then rotate it at regular intervals – usually daily or weekly. The movement adds oxygen to the material inside, speeding up the process. These composters come in many sizes with various methods of rotating the contents, including everything from smaller, rolling bins to larger, handle-turned set ups.

The advantage of tumbler composters is that the compost is ready much quicker. In fact, this style of composter can sometimes produce usable compost in as little as two weeks. They work best for people who need to produce batches of compost quickly.

The disadvantages of this style are that it requires more involvement in the composting process, and the batch process means you cannot add material until the current batch is finished.

Worm Tray Composters

This kind of composter uses worms to produce high-quality compost in a technique known as vermicomposting. As the worms naturally compost kitchen scraps and yard waste, they create their own waste called worm castings, which is a rich, organic material that makes plants thrive. Learn more about how vermicompost provides nutrients and prevents plant diseases from Cornell University’s award-winning research. Worm composters generally use stackable trays, with a new tray being added on top of the other as trays fill. The worms are able to move between trays as the material continues to stack up.

The advantages of this style are that you can continue to add material, the composting process occurs more quickly than bin styles, and the worms help control odors. This makes it ideal for smaller spaces or even indoor applications.

The disadvantages of worm tray composters are that you have to keep the worms alive for them to be successful. This means ensuring proper temperatures (generally between 40-80 degrees Fahrenheit) and material has to be added on a regular basis.

Which One is Right for You?

So how do you know which type of composter is right for you? You have to consider a few factors to determine which composter options best meet your needs. Check out our composter reviews below for the best recommendations. Some things you should keep in mind:

• Available Space – Composters range in size from smaller, indoor options to giant outdoor containers. Determine how much space you want to dedicate to composting before you begin shopping. If you’re an apartment dweller or have a small amount of space, you’ll want a more compact version.

• Processing Time – Tumbler and worm tray composters produce usable material faster than traditional bin versions. If you need smaller batches of compost produced more quickly they would be a better choice.

• Time and Involvement – Various models of composters will require different commitments from you in terms of time and effort. If you don’t want to be very involved in the process than a classic bin or option where you can just toss in scraps and let it go might be better for you.

• Extras – There are lots of extra features that may or may not matter depending on what you’re trying to do. Some options, like liquid collectors with spigots, are very useful if you’re nourishing a garden, but won’t be as useful if you’re doing the whole lawn.

• Start-Up – The model you decide on will have different start-up related activities and expenses. Again, you need to decide what you want to do. Some versions require a lot of assembly and can be tricky to work with, while other options are smaller but come fully assembled. Also, worm tray composters require an initial investment in worms and bedding materials.
