Step 3. Incorporate Brown and Green Materials

To establish a well-balanced compost pile, a mixture of “browns” (carbon-rich materials) and “greens” (nitrogen-rich materials) is necessary.”Brown material” encompass dried leaves, shredded newspaper, or straw, while “green material” consists of food scraps, potato plants remain, and vegetable scraps.

Initiate the layering process by adding a layer of brown at the bottom of your compost bin. This facilitates airflow and moisture absorption, preventing the pile from becoming excessively wet and emitting odors. Aim for a layer that measures approximately 4 to 6 inches in thickness.

Step 4. Continue Layering

On top of the browns, put the greens. You will mix in the potato skins at this point. Ensure a uniform distribution as you sprinkle a thin layer of potato peels over the layer of browns. Then add another layer of brown material to cover the peels.

Important! Make sure that each green layer is completely covered by a brown layer as you continue to alternate layers of green and brown. This layering method encourages a balanced carbon-to-nitrogen ratio within the compost pile, increasing decomposition while preventing foul odors.

Step 5. Provide Adequate Moisture to the Compost Piles

For your composting to be successful, moisture is necessary. The compost pile should always be wet, about like a sponge that has been wrung out. The compost pile might need water added if the potato peels are fairly dry. As you build the pile, wet each layer with a watering can or hose.

Important! Avoid overwatering as it can result in a wet pile and slow down the composting process. Aim for a moist but not soggy composition that is uniform across the pile. Maintain moisture levels between the recommended 50 and 60 percent.

Step 6: Turn the Pile

This action assists in the distribution of moisture, oxygen, and beneficial microorganisms, which hasten the decomposition of potato peels and other organic matter. Additionally, it helps maintain a consistent temperature throughout the pile.

  • The optimal temperature range for efficient composting typically falls between 110-160°F (43-71°C).
  • However, potato peels alone may not generate enough heat for ideal composting.
  • To encourage higher temperatures within the compost pile and avoid potato blight, consider incorporating other nitrogen-rich materials like grass clippings or manure.
  • Continue turning the pile every few weeks or when a decrease in temperature or compaction is observed.
  • Over time, the potato peels will break down along with the other compostable materials, ultimately transforming into nutrient-rich compost suitable for your garden.
