If you are a fan of gardening, you are probably aware of the importance of good soil for growing flowers and plants.

Remember to keep all your food scraps, leftovers, and even old newspapers to reduce food waste and create your own humus rich soil at home.

So, what is humus?

The simplest humus definition is that it’s a natural compost. Humus is made when decomposing leaves, animal matter, and other natural substances breakdown to create a squishy dark brown substance that's full of nutrients. It can be mixed with soil to create humus soil: a healthier, richer base for your gardening. Whilst humus is naturally-occuring, it is also easy to make your own humus rich soil in the garden.

What is humus made out of? 

Humus can be made out of any compostable or degradable materials. In nature, it tends to be made from decomposing leaves.

Making your own humus is a great way to combat food waste and transform your garden trimmings and these everyday foods and items can all be included in your humus:

  • Food leftovers: banana skins, vegetable peelings, eggshells and coffee grinds.
  • Grass clippings: any raked leaves, branch cuttings or mowed grass.
  • Recyclable paper including cardboard and old newspapers.

What are the benefits of humus soil?

The advantages of soil containing plenty of humus include: 

  • Humus creates many important nutrients for soil health, including nitrogen, that help plants grow. 
  • Humus can hold on to large amounts of water and will soak up moisture in the soil, helping soil rehydrate when it hasn’t rained. 
  • Humus breaks up soil, trapping oxygen and helping roots grow.
  • Humus can increase organisms in soil, enriching the soil and helping plants feed off the nutrients they create.

Ultimately, a humus rich soil will greatly improve the health of your soil, helping you make the most of your gardening.
