Banana as Fertilizer - Your Homemade Organic Fertilizer

See the photos below for the step by step guide to this easy homemade organic fertilizer recipe.

You only need two ingredients - over-ripe bananas and brown sugar

For this recipe, you will need:

1 kg over-ripe banana, and

1 kg brown sugar

Where to Buy the Over-Ripe Banana?

Go to any wet market or Asian market and they will be happy to sell you these bananas. You will get a discount as the over-ripe banana will start to ferment and be thrown away anyway.

It cost me only RM3 (US$0.70c) for 1kg of this over-ripe banana. The 1kg of brown sugar cost me another RM4 (US$0.95c). So in total, it cost me only RM7 (US$1.65). Cheap for a guaranteed beautiful blooms for your flowering plants.

You can use any type of bananas. It will work just fine. I prefer the very overripe bananas as the fermenting process will start faster. But avoid the very soft overripe banana that has the alcohol-like smell inside.

I have not tried plantains so I cannot vouch for its effectiveness.

Which Brown Sugar to Use?

As for the brown sugar, I prefer to use the dark brown sugar which has more molasses. Hence, it will have more iron, magnesium, calcium and potassium. These are all good for the plants as well as for the micro-organism in the soil medium.

Instructions on How to Prepare this Homemade Liquid Fertilizer

Together with the skin, slice the bananas into small pieces (in circles).

Place these cut bananas into a bowl.

Then sprinkle the brown sugar over the cut bananas. Mix them well.

Add Mixture Into a Container

Next, put the mixture into any container. I prefer my empty biscuit box which is already airtight.

If you use other types of container such as ceramic pots, cover the top with a cloth. But tie tightly so as to prevent ants or flies from entering.

Then put the lid on and leave at room temperature for two weeks. The mixture, with the help of the good bacteria, will unlock the nutrients in the banana and the brown sugar.

For my biscuit box, I put a piece of kitchen paper towel for added air-tightness!

1kg of this mixture will three-quarter filled this box container. So it has sufficient headspace.

Fermenting This Homemade Organic Fertilizer

I usually keep this container in a store room and let the mixture ferment in peace.

Otherwise, someone will open the box to look for biscuits!

You are ready to go on this homemade liquid fertilizer or rather fermented banana juice fertilizer on the eighth day.

How to Use this Homemade Liquid Fertilizer

Dilute this banana/brown sugar mixture at a ratio of 10ml to 1-liter water.

You can either apply directly to the soil or spray on the plant’s leaves.

You need to feed your rose plants and other flowering plants regularly. So apply twice a week to give them a boost of these nutrients.

The Recipe Again


1 kg over-ripe banana, and

1 kg brown sugar

Directions on How to Prepare and Use this Fermented Banana Juice Fertilizer

  1. Slice the banana and the skin into small pieces.
  2. Put these cut bananas into a bowl.
  3. Then, sprinkle brown sugar over the cut bananas. Mix them well.
  4. Next, put the mixture into any airtight container.
  5. Place it in a cool dry place for it to ferment for a week.
  6. You can use this fermented banana juice fertilizer on the 15th day by diluting the mixture at a ratio of 10ml mixture to 1-liter water. Apply it directly to the soil or foliar feed the plant.
  7. Please note that after two weeks of the fermentation process, not all the banana fruits and the banana peels will decompose. You will still have some balance of solid fruit and peels. But all the goodness has gone to the juice. So I normally throw them away. Before you do that, soak them in water to rinse any remaining balance of the juice that might stick around the fruit and peels.

Foliar Feeding is Better

Research at Michigan State University shows that foliar feeding is four to thirty times more effective when fertilizing a plant. The best time to foliar feed is between 7 am and 10 am.

If you prefer evening then spray after 5 pm. These are the time when the plant’s stomata i.e. the small openings on the leaves, are open.

But if you live in the tropics where the temperature is always above 25°C, then foliar feed at night. This is when the temperature is cooler as the best temperature to foliar feed is around 21ºC.

If the weather is very hot and dry, the night temperature may not be that low. Then skip that day and wait for other days when the weather is cooler.

Mix this homemade organic fertilizer thoroughly and use a sprayer that applies in as fine a mist as possible. If you do foliar feeding correctly, you will see visual results by the third day.

Why Foliar Feeding is Better

Banana as Fertilizer

Bananas are rich in nutrients that plants need to grow vigorously.

Nitrogen, Phosphorus, Potassium and a handful of micronutrients that banana contains, help your roses and other flowering plants produce bigger and beautiful blooms.
