Compost Tumbler Buying Guide

Most people get the dilemma in matching how the compost tumbler features will match up against their garden requirements. Well, below are some of the things to consider when deciding which of the above compost tumbler would be best to purchase.

How you plan to compost

You should begin the search by looking into how you compost. What this means is that if you want to add garden waste and kitchen scraps over some period or you want a one-time compost batch. If your plan is to add materials to the composter regularly, go for a dual-chamber composter. This will make it easy to fill up the second chamber as the first chamber is composting.

Using a one-chamber composter may not be ideal for such cases. Opening up the chamber as you add new material will admit cold air into the system, slowing the process. Besides, if you want to remove the compost, you will need to filter the already-decayed part, which can be daunting.

The only alternative option is purchasing a second compost tumbler. Go for a small composter such as the Envirocycle that doesn’t take up much space in your garden. Settling for a one-chamber composter, on the other hand, provides more space that can fit large amounts of compost material.

You should also consider the option of collecting liquid fertilizers. Some composters enable gardeners to collect liquid fertilizer separately, while others only form solid compost.

Ease of Use

Compost tumblers are designed to eliminate the strain of eliminating air from the compost mixture. This takes out the strain of using a rake, as turning the chamber makes everything possible. However, some composters are easy to use compared to others.

Composters with large capacities will get heavy when full. However, such units have an elongated spin bin that helps in creating momentum to swing the tumbler back and forth. The Mantis, for instance, has a gear-driven handle that makes rotation very easy.

Small compost tumblers are relatively lighter, but you should check how they work. Envirocycle, for instance, sits on the ground. To turn the unit, you will need to get down and turn it manually. This might be challenging for anyone with mobility issues. You should also reposition the barrel at the top to access the liquid compost compartment.

It is wise to go for composters that sit on a frame raised above the ground. You should also ensure that it has a locking mechanism that holds it in place when you are done turning the tumbler to keep it stable.

Compost Location

You should as well consider where the compost would be positioned in your garden. Will you need something small enough to be placed at the back porch? Or will it be tucked at the bottom of the garden that can accommodate something big? Is your garden landscape level?

Most compost tumblers such as the Envirocycle will not cope with slightly steep slopes. If your garden has a steep slope, consider a product with a broad base and low centre of gravity. That aside, note that composters attract pests, squirrels, foxes, rats and even bears. Therefore, ensure that it comes with a tight door with airtight latch to keep them completely shut.

You should also check on the weather conditions that your compost tumbler will be exposed to. Note that compost ripens much faster in hot climates. If your area experiences cold temperatures, go for a product with a black finish to absorb sunrays. Similarly, if you live in areas receiving heavy rainfall, go for a plastic model as it will be more durable compared to metal made composters.

Plastic composters may not also last long in areas with strong sunlight. However, some models, such as the FMCP outdoor compost employ UV-resistant plastics that inhibit degradation. Lastly, consider the aesthetics of your product of choice.

Bottom Line

One thing that gardeners like about compost tumblers is their ability to take the straining tasks out of composting. However, this can be enjoyed by choosing the right compost tumbler from the hundreds of models available on the market. We are hopeful that the guide above has provided you with the basic starting point and direction to take in your search.
