Join the home composting trend

Published Mon 20 Apr 2020

With all of us at home social distancing, a lot of households are embarking on home improvement projects including new ways to improve your garden. One of the best and easiest ways to improve the quality of your soil and ultimately the heath of your plants is through compost. 

Join the home composting trend The added benefit to compositing at home is reducing the waste your home produces.  In Victoria 36% of the average household bin is organic food waste, which goes straight to landfill. By getting involved in the home composting trend you could turn your kitchen scraps and garden waste into the ultimate organic soil improver for your garden while helping out the environment.  
 

Compost to reduce greenhouse gas emissions

Last year around 250,000 tonnes worth of food (enough to fill Melbourne's Eureka Tower) ended up in landfill. When organic waste is buried in landfill it is starved of oxygen and broken down by anaerobic decomposer organisms which generates methane.
When this same waste is composted above ground at home and exposed to oxygen, aerobic organisms break down the organic waste generating carbon dioxide.
Methane is 26 times more potent than carbon dioxide as a greenhouse gas and is a significant contributor to global greenhouse gas emissions.

Getting started

Compost piles or bins can come in many different shapes and sizes and a simple google search will help you choose the right size or system to suit your lifestyle and space. However, the principals stay the same and once you get going it’ll become a part of your daily routine. Here’s some tips on how to start an outdoor compost pile.
  1. Choose a shady spot in your garden to help avoid the pile drying out or overheating.
  2. Start your pile directly onto earth instead of on a paving slab or concrete to encourage earthworms and other organisms to help with the composting process.
  3. To deter unwanted midnight feasters or curious pets choose an enclosed / lidded system and bury the base.
  4. Start with a layer of course Brown (see below) material like twigs or autumn leaves so that air can circulate from beneath as well as above.

The ingredients

Green – Brown – Aerate - Check moisture - Repeat.

Composting requires mixing Nitrogen Rich (Green) ingredients with Carbon Rich (Brown) ingredients. To keep the pile moist and aerated you can start with a general ratio of 2-parts Brown to 1-part Green when layering your ingredients.
Typically materials that are green and moist tend to be high in nitrogen, and those that are brown and dry are high in carbon. Here’s a list to make it a bit clearer.
Browns (Carbon Rich) Greens (Nitrogen Rich)
autumn leaves vegetable scraps
straw coffee grounds
wood chips or sawdust grass clippings
bark manure
mixed paper plant cuttings
shredded newspaper fruit scraps
corrugated cardboard eggshells
egg cartons manure
 
Avoid adding meat (including bones), fish, wheat and dairy or waxed cardboard to your compost pile.
 

Top Tips from the Warralily Community Garden Group

  • To test the moisture level, squeeze the compost in your hand - water should release. If it breaks apart in your hand add some water.
  • Turn or aerate the pile once a week to promote an oxygenated environment. This will also help reduce strong odours.
  • Manure and coffee grounds are both high in nitrogen and will help increase the heat in the pile and energise the composting process.
  • If the mixture is too wet just mix in some dry brown ingredients.
In no time you’ll start to see a reduction of waste in your bin and after a few months your compost will be ready to spread on your garden.
