How Often Should I Turn My Compost Tumbler?

A tumbler is an effective way to accelerate the composting process, but how often you turn it is dependent upon a number of factors.

As soon as you understand when to turn compost, your materials can move more rapidly into and out of the bin, giving you more consistent results.

Tumblers can be an efficient and fast way to create compost, as they expedite the decomposition process. But to ensure optimal results, it is crucial that you know when and how often to turn it in order to prevent overheating and allow optimal mixing and aeration. A good rule of thumb would be turning at least twice per week – sooner if possible as microbes need time to develop themselves; once your compost reaches later stages of decomposition you may need to reduce frequency as microbes settle out – once established further along in decomposition the frequency can decrease accordingly.

If your compost is too hot, that could indicate that microbes are working so rapidly that they have exhausted all of the oxygen available in its mixture and led to its failure as an aeration system. To prevent this issue from happening, use a thermometer to gauge temperature; if its temperature becomes excessively hot, turn or mix your compost to help aerate it further.

Turning your compost is an efficient way of mixing its materials and improving aeration, giving organic material from outer layers an opportunity to move toward its center where temperatures and microbial activity is greater. Tumbling compost may still get messy but is less prone to infestation from elements and rodents compared with open piles of compost. Some models of tumblers feature vents for excess liquid drainage from within the tumbler itself that can then be used to water your garden later.

Many people complain that their compost tumbler doesn’t heat up. This could be caused by an imbalance between greens and browns – with greens providing nitrogen while browns adding carbon – the ratio is out of balance, needing a better balance to decompose properly. You can correct this problem by adding more browns into the mix; shredding all plant matter before placing it into the tumbler will also help ensure faster decomposition time.


Your compost tumbler’s contents require the appropriate level of moisture for effective decomposition, which you can monitor with either a moisture meter or just by looking at your compost; it should appear moist but not water-logged.

If your compost pile is too dry, microorganisms that aid the breakdown process could become overwhelmed and die out. This issue can be remedied by adding water or carbon-rich material into the pile; moisture levels should ideally range between 30-50% depending on local conditions.

When it comes to compost piles, regular turning is crucial to the process. Doing this helps aerate its contents and accelerates its progress; either using a pitchfork, shovel, compost tumbler hand crank or grooved barrel can do this work for you – always read your tumbler instructions as this could vary between models and it should be performed according to its instructions.

Compost tumblers can be an ideal solution for gardeners with small plots. Not only does their compact container keep the compost tidy and pests away, but the tumbling action provides ample aeration without needing an additional system like worm bins or other methods of ventilation.

Tumblers offer another advantage by accommodating ingredients that would normally not belong in a compost pile, such as meat, fat and fish scraps. As they’re turned regularly to prevent any unpleasant odors from developing.

Compost tumblers make compost management much simpler. You can keep one in an outdoor shaded space and they are much more compact. Plus, their sealed nature prevents pests from invading the system!

If you don’t plan on rotating the compost tumbler when adding new batches, it is wise to add greens first and browns after. This will prevent fruit flies or other pests from invading the pile, while you could add booster or compost activator (but only if necessary) which may assist the decomposition process.


Turning a compost pile regularly provides organic materials and microorganisms with ample oxygen, helping the process remain at full strength. Traditional turning is done using a strong garden fork or pitchfork; however, tumblers perform this same function more easily and less frequently.

Compost tumblers feature handles that make turning an easy process; in contrast to the laborious task required when turning piles of compost with forks or shovels. By turning your tumbler several times each week, soon you will have rich, healthy compost for use in your garden.

Tumbling your compost tumbler aerates it and generates heat that speeds decomposition, but too much tumbling may dissipate that heat and slow decomposition. Spinning it more than once daily as some do (children may find this activity enjoyable) also prevents material from reaching maximum temperatures.

Water is also an important consideration when determining how frequently a compost should be turned, since damp compost heats up faster but may also dry out and kill off microorganisms faster. A good rule of thumb for adding more moisture when the compost appears dry would be adding it only when required.

As a way of measuring the moisture in your compost, one effective method of doing so is smelling it. If its aroma smells sour, then too much moisture has accumulated and needs to be evaporated off before further use. Furthermore, wet compost indicates an imbalanced carbon to nitrogen ratio and should be resolved.

Some compost tumblers feature a basin at the bottom that collects liquid drippings from the mix as it aerates, known as compost tea and an excellent way to supplement regular chemical fertilizer application in gardens. Many people also use it as an additional method for feeding their gardens regularly with chemicals fertilizers.

Starting to use compost tea will depend on what kind of plants you are growing; most experts advise waiting until after your first turning before doing so. Therefore, having multiple chambers in your tumbler allows you to restart this process when one chamber becomes empty.


Compost tumblers allow you to aerate compost faster than conventional bins, but you still must turn them regularly in order to reap maximum benefit. Through turning, materials in your tumbler will mix more effectively for decomposition as the center heats up faster and breaks down than its edges, depriving oxygen in its core while killing microbes that live there; turning is therefore key in revitalizing them and speeding decomposition processes.

Turning your compost tumbler allows you to gauge its progress. If the smell of the pile is unpleasant, more frequent turning may be required; otherwise, sour smells could indicate overheating in which case adding additional brown material could balance ratios and help cool it down further.

Dependent upon the size and climate where you reside, turning your compost tumbler more frequently may be necessary than twice every week. A smaller tumbler’s contents can quickly heat up when exposed to direct sunlight, necessitating more frequent turning so as to maintain even decomposition and temperature regulation of materials inside it.

Most experts advise beginning your compost bin by layering brown material (high in carbon) like straw, sawdust or shredded paper before layering vegetable scraps and other green waste in three to four parts browns:greens ratio; this will absorb any extra liquid released when green waste breaks down over time.

Starting off a new batch can be daunting. In general, experts advise turning your compost tumbler once or twice each week for two weeks after starting up before slowing down as too much tumbling can dissipate heat and delay decomposition processes. Experts also recommend giving it several back-and-forth swings before completely overturning to ensure proper mixing and air circulation; you could also purchase models equipped with crank handles that make turning simpler.
