Three Ways to Make Banana Peel Fertilizer

This spring, we’re bananas for DIY fertilizer! Whether you’re an avid gardener or testing your green thumb for the first time, you’ll want to think twice before tossing out your banana peels. What you may consider trash can actually give your garden a boost!

At roughly 42% potassium, banana peels are a potassium powerhouse. Potassium is one of the “Big Three” nutrients that are essential to healthy plant growth. It strengthens plant immune systems, nourishes roots, prevents wilting, and protects plants during cold or dry weather. All in all, potassium is important for maintaining healthy growth.

Banana peels are also special because they don’t contain nitrogen. This makes them effective for growing low-nitrogen plants such as tomatoes, peppers, cucumbers, and radishes. Most store-bought fertilizers contain nitrogen, and too much nitrogen in these plants causes a lot of leafy growth but not much fruit or flowers.

Making your own fertilizer is not only good for your garden, it eliminates waste, too! Here are three ways to make banana peel fertilizer. We hope you find them a-peel-ing!

1. Liquid Banana Peel Fertilizer

Supplies:

  • Banana peels
  • Glass jar with lid
  • Water

Instructions:

Step one: Place banana peels in a jar. Be careful not to overload the jar.
Step two: Fill the jar with water and close the lid.
Step three: Let banana peels soak for about a week. Once they’re done soaking, remove the peels. Compost your banana peels, or reuse them using another method below!
Step four: Use the fertilizer to water the base of your plants. It may take a week or two to start seeing results, so be patient!

2. Dried Banana Peel Fertilizer

Supplies:

  • Banana peels
  • Scissors or knife

Instructions:

Step one: Cut banana peels into small squares, about an inch wide.
Step two: Dry banana peel pieces. Lay them directly in the sun, or use an oven. If using an oven, keep it at a low temperature with the door ajar.
Step three: Bury dried banana peels in the soil around your plant’s roots. Happy gardening!

3. Powdered Banana Peel Fertilizer

Supplies:

  • Banana peels
  • Scissors or knife
  • Food processor, coffee grinder, or blender
  • Optional: 3 eggshells, Epsom salt, and spray bottle

Instructions:

Step one: Cut banana peels into small squares, about an inch wide.
Step two: Dry banana peel pieces. Lay them directly in the sun or use an oven. If using an oven, keep it at a low temperature with the door ajar.
Step three: Using a food processor, coffee grinder, or blender, grind dried banana peels into a powder.
Step four: Mix the powder into your soil. Potassium power!
Optional: Grind three eggshells into powder. Combine with four tablespoons of banana peel powder and one tablespoon Epsom salt. Put the mixture into a spray bottle, and fill to the top with water. Shake until the powder and salt are dissolved. Spray this mixture at the base of your plants to promote healthy growth!
