Banana Tea: Homemade Flowering Fertilizer


Homemade fertilizer is also an option that’s discussed in cultivation groups. It’s not only used to solve deficiencies but also to fatten buds during flowering.

You’ll find plenty of potassium and phosphorus, the key nutrients in flowering, in the peel of a banana, and the banana itself if it is ripe.

True banana tea is actually a cold tea, despite the fact that it is commonly used to boil. If you leave it to soak as an organic ‘waste’ in water for enough days, it will begin to pass its nutrients into the water thanks to the formation of bacteria. Otherwise, if you boil it, you will not get as many nutrients and many will be lost due to high temperatures.

How To Make Banana Peel Homemade Fertilizer The Right Way:

  1. Let the water sit for at least 24 hours to clean it,
  2. Cut the banana peels into pieces,
  3. Put the pieces in a jar filling about 5 centimeters,
  4. Finish filling up to 3/4 of the total content with water,
  5. Cover it with a rag,
  6. Let it rest in the fridge for 3-5 days,
  7. Stir it a couple of times a day,

Note: Gasses in the jar are normal. However, if you see any type of mold accumulation, you must start again. The tea should smell sweet and of banana. If it has an acid or rancid odor, do not use it, try again, leaving it for fewer days.


After a few days, all that’s left is to strain it — so as not to leave food scraps on the soil.

To water, first you must dilute the tea in standing water, 1 liter of water for every half glass of tea — or 1 part of tea for every 10 parts of water. Then water your plants normally. This banana tea will provide your plant with significant amounts of potassium and phosphorous, as well as other beneficial microorganisms for the substrate.

This will provide your plant with significant amounts of potassium and phosphorous, as well as beneficial microorganisms for the substrate.

Don’t apply it too often. Depending on the size of your plant, applying it to the irrigation water once every week will be enough. It is important to never overdo your fertilizers; it’s better to apply a little many times than a lot once and overdo it.
