Can You Compost Banana Peels? (Methods, Tips & Uses)

Most of us love to eat bananas. But have you ever wondered if the banana peels could be reused instead of going to landfills? You might be happy to know that banana peels have innumerable benefits and can be used in gardens. But how? Can you add banana peels directly to the soil? Or can you compost banana peels? Let’s dig deep to find the answer.

Banana peels are compostable and add organic matter to your soil. They are an excellent soil additive as they are high in potassium, which is an essential nutrient for the development of flowers and fruits. Cut the banana peels into small chunks before adding them to the compost pile for faster decomposition.

How To Compost Banana Peels?

Banana peel breaks down quickly, making it a great composting material. Banana skin can be composted through different methods like hot composting, cold composting, or can be used in worm bins.

Now that you know banana peels are compostable, here is the step-by-step process you need to follow for composting banana peels.

Banana Peels

Step 1. Cut the banana peel into small pieces

Collect the banana peels and remove their stickers (if any).

Now wash the peels and cut them into smaller pieces, ideally 1-2 inches, to escalate the decomposition process. The smaller the banana peel, the quicker it will decompose.

Step 2. Add brown materials to your compost bin

Make a layer of brown materials by adding wood chips, shredded cardboard, dry branches, straw, ash, etc. Make sure to chop them into smaller pieces.

Brown materials are rich in carbon and provide food for the bacteria and fungus in the compost pile.

Step 3. Add Banana Peels to your Compost Bin

Mix banana skin with other green materials like food waste, kitchen scraps, and yard waste. Cut the vegetable and fruit peels into smaller pieces and then add them to the compost pile, making a 2- inch layer of green materials.

Green materials are rich in nitrogen and help in the growth of microbes.

Step 4. Repeat the layering process

Now, repeat the process by altering the layers of green and brown materials.

Once you have layered the beds with green and brown materials, cover them with a firm layer of soil of 2-inches.

Green materials contain water, and brown materials absorb excess water. So it is essential to balance both the green and brown materials in your compost bin.

Step 5. Add water to your compost pile

Your compost pile needs to be moist for carrying out the decomposition process. Add adequate water to your compost pile every 3-7 days. You can always add some extra brown materials if you feel there is excess water in your compost heap.

Step 6. Turn the compost pile

Banana peels require oxygen to decompose quickly. To keep the compost pile aerated, you need to turn it in 3-7 days or poke holes with a pitchfork.

Proper aeration helps the microbes act upon and break down the compost quickly. Provided with ideal conditions, your compost may be ready in 3-4 weeks.

Can Banana Peels Go To Worm bins?

Yes, banana peels can be used for vermicomposting. Red wiggler worms love to eat banana peels. When using banana skin in the worm bins, remember to cut them into small pieces and mix them with other green materials.

After digesting the food, the worms produce worm casting. This is called vermicast or vermicompost, and they act as organic fertilizer for plants.

In worm bins, banana peels only take 2-3 weeks to break down entirely if they are adequately maintained.

Can You Bury Banana Peels Directly Into The Soil?

Banana peels can be added directly to the soil, but it takes more time to decompose. Also, when you plan to add banana peels directly, you need to dig the soil and put the peels inside it instead of throwing them open on top of the soil.

However, banana peels need air to decompose. So, covering them deep in the soil might hinder the oxygen supply and slow down the decomposition process. Therefore, composting banana skin is considered the best method.

Moreover, it is estimated that if a whole banana peel is left on the soil, it will take up to two years to decompose completely.
