Cut peels into small pieces to make the tea and put them in a container with a lid. Add 250 milliliters of water per apple, cover, but don’t close completely
Place the jar in a shady spot and after three to five days, strain the peels out of the solution and throw them into your compost to continue reusing them.
Instead of brewing, you can add the chopped peels directly into the soil, but they will need to decompose for a few weeks to a few months for the nutrients to release.
