Save those nutrient explosive peels when you eat or bake with those bananas!

Your plants will give you a high five for feeding them with potassium rich banana peels. Most plants thrive on the potassium rich "peel smoothies".


If you don't have a smoothie maker, you can use a food processor but it will have to be processed longer in order to make the liquid find and dissolve the peel chunks. You can actually put the peels around your plants and achieve the same results but it will take a lot longer for the plants to benefit from the peels.


Using my smoothie maker produces a finer pulp with much less chunks of peel. Which ever method you use will be ok for your plants but the finer the peels are ground, the faster they will reach your plant's needs.

I would not suggest using this on house plants until you can set the plants outside in the spring as you may encourage fruit flies to come.

After I finished the processing I poured the "peel smoothie" into a jar to store till spring to use around my roses and other plants.

Potassium is important to plant growth and development. Potassium helps:

  • Plants grow faster
  • Use water better and be more drought resistant
  • Fight off disease
  • Resist pests
  • Grow stronger
  • Produce more crops
  • With all plants, potassium assists all functions within the plant. When a plant has enough potassium, it will simply be a better overall plant.

    Do you use this straight or dilute with water? How much and how often?

  • Jackie Jackie on Jun 21, 2023

    I will certainly give this a go but I need to know how long I can store it before it ends up in the bin??

  • Jenny Jenny on Jul 12, 2023

    I'm going to try using this with a rose bush that I have to move. Maybe it will help with the shock of moving?

    Have done this mixing with old coffee grounds and egg shells.

      careful old coffee grounds may become too acidic for some garden plants, however a lot of shrubs& bushes love them, an left over coffee-cooled!

    You can also just put the banana peelings in water, place in a window sill for a could of days & use the liquid for potted plants. I then put the peels around my roses or mulch pile.
