Testing Compost Tumblers



You have often seen the advertisements: "You can now have dark, wealthy compost in a couple of days!" How much of an appealing message. Regardless of whether you grow flowers, veggies, herbal treatments or houseplants, compost is "black gold" within the garden. We not have enough, and should not allow it to be quick enough. Compost tumblers, the advertisements say, can provide us a stable supply every few days.

Designed so that you can crank, turn or roll the container to show and aerate the compost, tumblers are available in several dimensions.

Prior to runing out and purchase one, however, remember that individuals head lines are advertising hyperbole at the best. Within our tests, tumblers didn't produce finished compost any quicker than a properly-handled compost bin or open pile.

To be certain, the elements seem to be composting faster because you'll probably turn the contents more frequently inside a tumbler, thus presenting air — among the four vital elements (others being nitrogen, carbon and water) — that's essential to turn vegetable matter into compost. But when you build a wide open pile exactly the same size like a tumbler's capacity, make use of the same elements both in and switch outdoors pile if you rotate the tumbler, they'll produce compost within the same general time period. So, why wouldn't you purchase a compost tumbler?

Last summer time we carried out a area test of numerous compost tumblers versus open compost piles. Although the majority of us at MOTHER use cold composting techniques (replacing here we are at the job of maintaining a warm pile), we went a warm pile like a control.

Under our environment conditions, both open (hot) pile control and also the tumblers produced wealthy, finished compost within 10 days — far in the fourteen days a few of the producers claim. The tumblers were certainly simpler to make use of than turning a wide open pile having a pitchfork, but they didn't substantially boost the speed of production when in comparison to some correctly handled open pile. Easy turning is most likely the primary benefit tumblers offer, but because you will see below, many are simpler to show than the others.

Even though the decomposition time isn't elevated, compost tumblers will have advantages additionally to help ease of turning. Generally, they're clean, neat, inconspicuous, pest-resistant and odor-free. Due to this, tumblers frequently may be used in urban and suburban areas, where local laws and regulations or limited covenants may stop open compost piles.


One enjoyable surprise throughout the testing, with what switched to be considered a drought year, could be that the enclosed tumblers maintained moisture much better than outdoors pile, which needed to be watered frequently.

Compost tumblers fall under four general groups according to their construction:


Crank-operated drums. A flat mounted drum rests on the elevated framework. A crank set up allows you switch the drum easily, as the internal baffles help mix the types of materials, adding air.

Since the drums are elevated relatively high, draining them is straightforward. Basically push a wheelbarrow underneath the drum, squeeze door and open it up. Compost flows into the wheelbarrow.

This kind of tumbler has a tendency to cost about two times around other kinds. But, just like other things, you receive that which you purchase. Within this situation, you trade money for easy operation.

The Mantis ComposTwin and also the ComposTumbler are good examples of the design the previous includes a double drum and also the latter includes a single drum (obtainable in two dimensions).

Center-axle drums. A up and down mounted drum rotates around a main, horizontal axle based on a wood, metal or PVC frame. Operation is usually easy, particularly using the appliances have doorways on finishes.

The central axle functions to interrupt up and blend the types of materials. Many of these tumblers are mounted low down, however, so draining them could be a chore unless of course you've got a low-boy wheelbarrow which happens to fit under them.

The Urban Compost Tumbler (UCT) and also the Tumbleweed are this kind.

Base moving drums. A flat set up drum comes on the ground-level base. A number of them really have paint rollers, while some have molded rounded suggests suspend the drum and allow it to rotate.

Clearly, the tumblers with paint rollers are simpler to show. To make rotating simpler, a number of this style have steps molded in to the body, so that you can make use of your ft and legs to show them, thus theoretically reducing back strain.

Since the base moving tumblers virtually sit on the floor, draining them could be awkward. You need to shovel the compost out — through relatively small openings — instead of flowing it.

Usual for this design would be the Envirocycle, the Step-lower Composter and also the EZ Composter.

Roll-Around Sphere Compost Tumblers. They are giant molded angular balls that you simply fill with composting material after which roll around your yard. The concept is initially intriguing used, however, they have a tendency to he probably the most awkward to make use of and the most challenging to empty.

Roll-around composters aren't actually round, but they are faceted just like a geodesic dome. Consequently, they merely roll on which could be their equator. And, rather than moving just like a snowball, they swing left or in sharp arcs.

The heavier they're loaded, the less control you've.

The Bio Orb and also the Large Batch Composter are good examples of the style.

Whichever unit you select, you should know of certain operational factors:


1) Ignore recommendations to make use of compost accelerators. About 50 % the producers still recommend this practice, yet comprehensives research has proven that such chemicals don't have any significant impact on the composting process.

2) The proportion of eco-friendly material to brown is much more essential in a shut tumbler compared to a wide open pile. If you do not add a minimum of 40 % browns, you'll finish track of a slimy, smelly mess rather than compost.

If little else can be obtained, have a bag of leaves or perhaps a bale of hay handy and employ it as essential to keep up with the balance. Generally where customers have reported poor results, it works out they've been adding only grass cuttings and kitchen scraps towards the unit.

3) All tumblers are pest-proof to rats, dogs along with other creatures — to not bugs. Whenever you open a tumbler, be ready for a cloud of gnats to emerge. The truth is, the gnats hover over open compost piles, but you're less conscious of them since you don't encounter them in mass.

4) Monitor the moisture content. Tumblers retain moisture letter than open piles, so you don't have to add much. Usually, grass cuttings alone provide ample moisture.

Your working pile should seem like a clamp sponge.

Whether it's wetter than that, leave the doorway open some time therefore it can dry up. From time to time you might want to add a tiny bit of water. If that's the case, add a maximum of just one cup at any given time, and make certain to tumble the contents after each addition.

5) Air is vital towards the composting process. Periodically check to guarantee the vents inside your composter weren't clogged by organic material. If you feel this mixture is not getting enough air, rotate tile tumblers more often.

Compost Tumbler Features: Benefits and drawbacks


After you have made the decision which type of tumbler you would like, consider the specific options that come with each. It is the small things that may do or die a design.


For example, compare the Envirocycle towards the EZ Composter. The previous includes a hinged door. The second includes a round hatch with carefully threaded screws.

Consequently, loading and unloading the Envirocycle is substantially simpler than loading and unloading the EZ Composter, with a hatch that's hard to screw lower even if your unit is totally new, not to mention after grime and debris clog the threads.

Among center-axle types, some, like the Tumbleweed, open at both finishes, while some, like the Urban compost Tumbler, open only atone finish. Getting openings on finishes makes loading and unloading simpler. However, the additional ventilation from the UCT's patented core-oygenation system, which precludes getting both finishes open, might he well worth the trade-off.

Capacity is also an problem. Many models are available in several size. In the beginning blush, the bigger size appears to create sense since it produces more compost within the equivalent time like a more compact one.

However the bigger one may also he heavier and much more hard to operate.

There's another facet of ability to consider. Composting speed is really a purpose of the final products to he added. That's, you will not i believe load of compost unless of course you've include a full load of organic material. This does not mean you cannot add material just a little in a tune.

What it really entails, however, is the fact that "time for you to completion" is measured from all of the individuals small additions.

Due to this, you might want to have several unit. Begin by completely filling one with a combination of brown and eco-friendly compost material. Good examples of brown material are fine mood chips, brown weeds, hay, leaves and kitchen scraps good examples of eco-friendly material are grass cuttings, eco-friendly garden cast-offs and manure.

That can be a batch "cooks," you are able to gradually fill another unit.

This is actually the idea behind the ComposTwin: You could have one bin filled and composting when you are adding fresh elements towards the second bin.
