Questions worth asking
How much compost can a large tumbler produce?
A 37-gallon tumbler can produce about 5 to 10 gallons of finished compost every few weeks, depending on your mix and how often you turn it. Larger 75-gallon models yield more but take up similar space.
Is a large tumbler too heavy to turn when full?
It can be heavy, but most tumblers are designed to be rotated when full. Look for models with a crank handle or a balanced drum. Some owners add a brick or weight to help rotation, but that is not recommended.
Can I put weeds and diseased plants in a compost tumbler?
A tumbler that heats up can kill weed seeds and pathogens. However, if the compost does not reach high temperatures, they may survive. It is safer to avoid diseased plants and persistent weeds.
How often should I turn my compost tumbler?
You should turn it every 2 to 3 days to aerate the pile. Some gardeners turn daily for faster results. The more often you turn, the quicker the compost breaks down.
Do compost tumblers smell?
When balanced correctly with browns and greens, they should not smell. If it smells, add more dry materials like leaves or cardboard. Turn the tumbler to mix and aerate.
Can I use worms in a compost tumbler?
Tumblers are not ideal for worms because they get disturbed by tumbling. Worms prefer a static bin. If you want vermicomposting, use a separate worm bin.
How long does it take to make compost in a tumbler?
With regular turning, you can get compost in 3 to 6 months. Some models with dual chambers allow you to harvest one side while the other continues, speeding up the overall process.
Where should I place my compost tumbler?
Place it in a spot with partial sun to help heat the pile, but not too much direct sun that dries it out. Ensure you have easy access for loading and turning. Also, keep it away from wooden structures to avoid staining.
Are compost tumblers rodent-proof?
Most tumblers are elevated and sealed, which deters rodents. However, if you have a severe rodent problem, you may need additional precautions like a wire mesh base.
Can I compost in winter with a tumbler?
Yes, you can, but decomposition slows down in cold weather. Insulating the tumbler or moving it to a warmer spot can help. Keep adding materials and turn occasionally.
Our pick
For most small gardens, the FCMP Outdoor IM4000 is the best balance of capacity, durability, and ease of use. If you have a slightly larger budget and want the biggest capacity, choose the Lifetime 75 Gallon. For those on a tight budget, the Miracle-Gro or Goplus offer good value, but be prepared for a shorter lifespan.
