From the page: The whole orange has a purpose
Idea 8
Citrus composting
Orange peels are rich in nitrogen, potassium and aromatic oils, and have become homemade fertilizer in urban gardens all over the world. The soil's microorganisms break down this organic matter and return the nutrients to the roots — nature recycling in a closed cycle.
What you need
- Orange peels and pulp (and other fruits)
- A bucket or box with a lid
- Soil or ready-made compost to start
- Dry leaves, sawdust or shredded cardboard
- A small shovel or wooden spoon to turn the mixture
How to make it
-
1
Chop the peels into small pieces, because the smaller the surface, the faster bacteria and fungi can break them down.
-
2
In the bucket, alternate layers of citrus material with layers of dry material, such as leaves or cardboard — this balance prevents strong smells and excess moisture.
-
3
Start and finish with a layer of soil, which brings in the microorganisms responsible for decomposition.
-
4
Stir the mixture once a week to oxygenate it, because without air the decomposers stop working and bad odors appear.
-
5
Keep the mixture damp like a wrung-out sponge, watering only if it is too dry.
-
6
In two to three months, when the material is dark and smells like forest soil, it will be ready to use.
Finishing touches
Use the fertilizer in pots, gardens and seedlings — the oranges from your home going back to feed the plants. In small amounts, citrus doesn't bother the compost bin; just avoid piles made only of peels.
