From the page: Banana peels are pure gold
Idea 6
Powerful liquid fertilizer
Fermenting banana peels in water is an old technique among those who grow in small spaces: garden grandmothers and coffee growers always saved peels for "banana tea." It works because bananas are rich in potassium and phosphorus, nutrients that fermentation releases into the water, making them ready for the plant to quickly absorb through the roots.
What you need
- Peels of 3 to 4 bananas
- A jar or 2-liter bottle with a lid
- Water
- A sieve or cloth for straining
- Watering can
How to make it
-
1
Chop the peels into small pieces — the smaller they are, the faster the nutrients move from the peel into the water.
-
2
Put everything in the jar and cover with water, leaving about two fingers of space at the top, because fermentation releases gases and needs room.
-
3
Cover without sealing airtight (or open it a little every day) to release the gases and keep the jar from bulging.
-
4
Let it rest for 3 to 5 days in a cool spot, stirring once a day — when the water turns tea-colored and smells lightly sweet, it's ready.
-
5
Strain the liquid and dilute one part of the tea in ten parts of water before watering — straight, it's too strong and can burn the roots.
Finishing touches
Use every 10 to 15 days on flowering and fruiting plants, which love banana potassium. The strained peels can still go straight into the pot as soil cover.
