Cold Tea — Compost Tea
This homemade fertilizer that is most discussed in the cultivation groups. It is not only used to fix potassium deficiency but also to fatten buds.
You’ll find plenty of Potassium and Phosphorus, the key nutrients in bloom, in the peel — 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 an organic ‘waste’ in water for enough days, it will begin to pass its nutrients into the water thanks to the formation of bacteria.1 Otherwise, if you boil it, you will not get as many nutrients and many will be lost due to high temperatures.
How to get it right:
- Let the water sit for at least 24 hours to clean it.
- Cut the banana peels into pieces.
- Put the pieces in a jar filling about 5 centimeters.
- Finish filling up to 3/4 of the total content with water.
- Cover it with a rag.
- Let it rest in the fridge for 3-5 days.
- Stir it a couple of times a day.
Note: if you see that there are gases in the jar it is normal. On the other hand, if you see any type of mold accentuating, we must start again.
The tea should smell sweet and banana like. If it has an acid or rancid odor, do not use it, try again, leaving it less 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. And water enough to water your plants normally.
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 every 1 week will be enough. It is important never to overdo with fertilizers, better to apply a little many times, than a lot and to overdo.
