Banana peel gardening hack: Stop burying banana peels in soil; try these 3 methods instead

Banana peels are often described as a natural source of nutrients for plants. They contain potassium, phosphorus, calcium and magnesium, all of which play a role in plant growth. However, that does not mean fresh banana peels should simply be buried in garden soil.

Banana peels are not a complete fertilizer because they provide little nitrogen and can take a long time to decompose. As a result, plants may not get the nutrients they need quickly enough. There are, however, several better ways to reuse banana peels in the garden.

Why you should avoid burying banana peels in soil

Burying banana peels directly in soil is a common gardening practice, but it may not be as beneficial as it sounds. Soil microorganisms must first break down the peels before their nutrients become available to plants. Since decomposition can take considerable time, the nutrients may not be released when plants need them.


Fresh banana peels can also attract unwanted visitors. Rats, raccoons and possums may be drawn to the food waste, while fruit flies, gnats and other insects can also become a problem. Decomposing peels may additionally produce unpleasant smells and create conditions that encourage fungal growth.

How to use banana peels in your garden

Instead of throwing banana peels away or burying them around plants, you can process them in ways that make them more useful for your garden.

Add banana peels to compost

Composting is one of the simplest ways to recycle banana peels. As they decompose with other organic materials, they add nutrients such as potassium, phosphorus, calcium and magnesium to the finished compost.

Cut the peels into smaller pieces before adding them to the compost pile. Mix them with carbon-rich materials such as dried leaves or cardboard. Keeping the peels covered within the compost can also help prevent pests from being attracted to the pile.

Turn the compost regularly to improve airflow and encourage faster decomposition. Once the compost has fully broken down, it can be incorporated into garden soil.

Make banana peel fertilizer tea

Banana peels can also be used to make a homemade liquid fertilizer. Although research into banana peel tea is limited, studies examining banana peel-based fertilizers have found potential benefits for plant growth.

To make the tea, chop banana peels and place them in water for 24 to 48 hours. Strain the liquid and use it to water plants, seedlings or garden beds.

However, banana peel tea should be considered an additional source of nutrients rather than a replacement for a balanced fertilizer.

Turn banana peels into powder

Drying banana peels is another way to make them easier to use in the garden. Place the peels in sunlight for several days or dry them completely in an oven.

Once they are fully dry, grind them into a fine powder using a blender or food processor. The powder can be mixed into soil before planting or sprinkled around established plants.

The nutrients will be released gradually as the dried material breaks down.

Banana peels can be a useful way to recycle kitchen waste, but they should not be treated as a substitute for complete plant nutrition. Composting them, making a peel-based liquid or turning them into powder can be more effective than placing fresh peels directly into the soil.
