How long does it take?
The time it takes to get useable compost depends on:
- The type and quantity of materials in your bin
- The time of year
- How often you turn your compost
Depending on the conditions your compost will be ready in 4 - 6 months. The ready compost will be crumbly and dark brown. You should not be able to recognize the original materials that were put into the bin, although some twigs and eggshells may still be visible.
Once the first layer of twigs and branches have been put into your Green Johanna more brown and green materials can be added as they become available. Where possible, try adding one part of brown materials to two parts of green materials in your Green Johanna, as this will create the best compost.
Scattering and mixing materials will help speed up the composting process. New green materials should be covered with some brown materials, as this will deter flies.
Adding air speeds up the composting process as it enables the bacteria that break down your kitchen and garden waste to work effectively.
The best way to put air into your compost is to turn it using one of the following methods:
- Use the aerator provided to gently mix the compost up and down.
- Empty the contents of your Green Johanna and turn them with a garden fork before returning them to the bin.
- Turn your compost while it is still in the bin using a garden fork.
Your compost needs the right amount of moisture to work. You can tell if your compost is too wet or dry by gently squeezing a handful. If a couple of drops of water emerge between your fingers the compost has the right amount of moisture in it.
If your compost feels dry and dusty, add some green materials and some water.
If your compost feels slimy or soggy, mix in some brown materials such as cardboard/paper, sawdust or small twigs.
