🧴 How to Make It:
Step 1: Chop the Banana Peels
Cut the banana peels into small pieces. This helps them break down faster and release nutrients more easily.
Step 2: Add to the Bottle
Place the chopped peels into the empty bottle. If using coffee grounds or sugar, add them now too.
Step 3: Fill with Water
Fill the bottle with water, leaving a little space at the top. Screw the cap on tightly.
Step 4: Let It Ferment
Leave the bottle in a cool, shaded spot for about 3–5 days. Give it a gentle shake once a day. During this time, the water will become infused with nutrients as the peels ferment.
Step 5: Use on Plants
After 3–5 days, pour the liquid (diluted with more water if needed) around the base of your plants. Use it once every 1–2 weeks for best results.
Tip: Don’t forget to compost the leftover peel pieces!
