How to make humus soil: A step-by-step guide

Read below for our quick and simple step-by-step guide to making humus soil.

  1. Choose your spot. You need to have a decent amount of space in your garden to add your compostable materials; or alternatively, invest in a compost container or bin.
  2. What is humus made of? There are certain things that should (and should not!) be added to your humus compost heap.
    • Good for humus soil: Vegetables, leaves, fruit skins, grass clipping, old newspapers and egg shells (not whole eggs!)
    • Bad for humus soil: Metal, plastic, chemicals, animal food, meat, or garden clipping which were treated with pesticides.
  3. As a general rule, if you wouldn’t eat it, don’t put it in: it shouldn’t be fed to your plants either!
  4. Consider adding horse manure to your mix. No other animal (or human) faeces should be added.
  5. Turn your compost regularly. Preferably you should be turning your pile at least once per day to help the process happen quicker.
  6. Ensure that it neither becomes too wet or too dry; it should just be damp.
  7. Keep an eye on the way that the compost looks. In time it will become humus, which is a dark, spongy, jelly-like material.
