Composting Apples: The Ultimate Guide

Composting apples is an excellent way to reduce food waste while producing nutrient-rich compost for your garden. This comprehensive guide covers everything you need to know about adding apples to your compost pile.

Benefits of Composting Apples

Composting apples offers numerous advantages:

  • Nutrient-rich addition: Apples provide nitrogen, phosphorus, potassium, calcium, and magnesium to feed composting microorganisms. As the apples decompose, these nutrients are released into the compost.

  • Natural sweetener: The sugars in apples serve as an energy source for beneficial composting bacteria and fungi. This speeds up the breakdown of other materials.

  • Moisture source: The high water content in apples helps maintain the ideal 40-60% moisture level in the compost pile.

  • Attracts decomposers: The apple flesh draws in worms, bacteria, and fungi that drive the composting process. More decomposers means faster, more efficient composting.

  • Greater aeration: As apple chunks decompose, they leave behind air pockets for improved oxygen flow in the compost. Proper aeration prevents anaerobic conditions.

  • pH buffer: Apples contain malic acid which can help buffer pH levels. This creates favorable conditions for composting organisms.

  • Reduces waste: Composting apple peels, cores, and spoiled whole apples cuts down on organic waste going to landfills.

What Parts of Apples Can Be Composted?

Nearly every part of the apple can be added to compost:

  • Peels
  • Flesh
  • Seeds
  • Stems
  • Core
  • Rotten or damaged whole apples

The main exceptions are stickers, bands, or any non-organic material on the apples. These should be removed before composting.

Composting Whole vs Cut-Up Apples

Whole apples take longer to break down but can be composted. Cutting apples into smaller pieces speeds decomposition.

Apple chunks provide more surface area for microbes and allow better air circulation. Optimal size is 1 inch chunks.

Cores and peels decompose the fastest as they have less skin to protect them.

Chopped apples are best for hot composting methods to accelerate decay. Whole apples work for slower, cold composting.

How to Prepare and Add Apples to Compost

Follow these steps for composting apples:

  1. Remove any stickers, bands, or ties from the apples. Compost only the organic material.

  2. Wash apples if needed to remove dirt or debris. Soap is not required.

  3. Cut into smaller chunks if desired, for faster composting.

  4. Mix apples into compost pile, burying them under 10-12 inches of other materials.

  5. Add dry browns like leaves or paper to balance the apples' moisture.

  6. Turn or stir pile to incorporate apples fully. Monitor temperature and moisture.

  7. Continue burying additional apples as you add them to maintain a balanced pile.

Apple Composting Tips

  • Add a 2:1 ratio of browns like dried leaves or wood chips to balance the greens.

  • Use apple chunks rather than whole apples in hot, fast composting systems.

  • Bury rotten or moldy apples in the center of the pile to break down fully.

  • Avoid adding too many apples at once. Add them gradually over time.

  • Turn or aerate piles with excess apple waste to prevent bad odors.

  • Monitor moisture and add water or browns if pile gets too wet. Ideal is 40-60% moisture.

Composting Apple Pomace and Scraps

Apple pomace is the pulpy material left after juicing or cider production. This nutrient-rich waste can be composted.

Dried pomace lasts longer in the compost than fresh wet pomace. Compost pomace in batches over time rather than all at once.

Apple scraps from food prep like peels, cores and trimmings can also be composted. Chop large pieces for faster breakdown.

Troubleshooting Apple Composting Problems

Bad smell: Excess apples or moisture causes anaerobic rotting. Turn pile and add browns.

Slow decomposition: Add more greens, turn pile, check moisture. Chop apples into smaller pieces.

Pests: Rodents or wildlife attracted to fruit. Bury apples fully, install secure bin.

Clumpy compost: Too much unchopped apple waste. Break up clumps and turn pile.

Nitrogen deficiency: Insufficient greens. Add more fruit and veggie scraps like apple waste.

FAQs About Composting Apples

Can you put whole apples in compost?

Yes, whole apples can be composted but will break down slower than chopped apples. Cutting fresh apples speeds decomposition so it's recommended for hot composting. Whole apples work well for slower cold composting.

Should apple cores and peels be composted?

Apple cores and peels are ideal compost additions. With the flesh exposed, they decompose rapidly. Peels provide nutrients, and cores are a rich nitrogen source. Compost them routinely instead of trashing them.

What's the best way to compost rotten apples?

Rotten apples decompose quickly but may attract pests. Bury rotten apples at least 10 inches deep in the center of the compost pile. Turn piles with rotten apples regularly to speed breakdown. Adding dry leaves prevents odors and pests.

Can you put apple seeds in compost?

Apple seeds can be safely composted. They contain cyanide but in very low concentrations. Composting temperatures will easily neutralize the toxins. Crush seeds if desired but leaving seeds whole is fine. Most will not sprout due to compost conditions.

Can you compost diseased apple waste?

It's best not to compost apples with transmittable diseases like apple scab or fire blight. For general mold, compost diseased apples as long as they break down fully. Always bury diseased waste in the hot center of the pile and monitor for smells or growth.

In summary, apples are a valuable addition to any compost pile. By following proper preparation, mixing, and maintenance steps, you can successfully compost apple waste from your kitchen or garden. Adding apples to compost boosts nutrients, balances moisture, speeds decomposition, and reduces food scraps sent to the landfill. Composting apples is easy and beneficial for creating richer, healthier soil.
