Outdoor Compost 

Ideal for Composting Garden- and Food Waste at Home

Our compost bins work great in small gardens. It looks neat, the lid keeps pests out and the opening works great when you want to harvest your compost.  Your household organic waste will break down quickly if you follow a few golden rules. 

A noteworthy ratio to follow: 60% browns; 30% greens and 10% manure and fill bin to the top. 

Firstly start with a layer of wet “brown material” (carbon) for instance twigs, brown leaves, egg carton, wet pizza boxes, shredded toilet paper rolls, cardboard or paper at the bottom.

Alternate with “green material” (nitrogen) like vegetable- and fruit peels, Bokashi fermented food waste, coffee grounds, green leaves or grass clippings in the outdoor compost bin.  

Your top layer should be brown material, to limit smells and flies. You can’t add meat, fish, cooked foods unless it has been treated with Bokashi. The treated food waste will act as an accelerator and speed up the composting process.

The aim is to use different types of materials in your compost heap as this bring more nutrients.  To make even better compost, add manure from horses, cow, chickens etc. (never human, cat or dog manure). 

Use your compost thermometer (can order from us) to measure the heat of your heap. 

Within the first 10-15 days, turn your heap after 72 hours of 55’C or 48 hours of 65’C, to break down pathogens and weed seeds.  Repeat this step. 

Never let your compost go above 73’C, as you will lose minerals and nutrients and anaerobic bacteria will grow.   

Turn your heap again and then let it rest.  You want the fungi to grow, that is why you don’t turn it too much and regulate the heat.

Keep the compost at a 50% moisture level, thus not soggy wet as it will become smelly due to the anaerobic conditions.   

Limit grass clippings to a maximum of 5cm per layer (you can also mix leaves into it to get oxygen in).

Compost is ready once it has completely broken down, is no longer hot and has a 70% dark chocolate colour.  Never work compost into your soil, as it breaks the soil structure.  Only add the compost on top of your veggie- or flower garden’s soil.

Outdoor Compost Bin – Easy Steps

Step One

Put your Compost bin on bare soil in semi shade. (If you have to put it on concrete, add a 10cm layer of compost or soil at the bottom to absorb leachate.)

 Place 10-20cm of twigs, straw or brown leaves to start.

Step Two

 Alternate between layers of green (nitrogen); brown (carbon) materials and manure.  

Greens: Green leaves, grass clippings, coffee grounds, fruit peels, egg shells, tea bags, Bokashi fermented food.

Browns: Brown dried leaves, shredded newspaper, toilet paper rolls, cardboard and egg cartons.

Step Three

Keep the Compost bin moist, but not wet.

Turn the pile to get oxygen in.

Step Four

Harvest compost when dark chocolate colour, has a crumbly texture and is completely broken down.

Use compost on top of your soil.  Never work compost into the soil, as it breaks the soil structure, kills microbes and increases weeds.

Problem Solving:

Outdoor Compost Bin

 

My compost is cold, it doesn't heat up?
  • Add more green material like grass clippings
  • Add manure to get the heat up
  • Add compost activator (Contact Circular Homes)
  • Add more water if it looks dry and turn the pile
My compost is stinky and has flies?
  • Add more brown material (carbon) like dried leaves
  • Always cover any food with brown material (carbon) or soil
  • Ensure the bin is not too wet, only keep it moist
I have bugs in my compost?
  • Ants:  Add more water and turn the pile.
  • Slugs or snails: Great composters, but we don’t encourage them.  You don’t want them in your veggie garden as they do make a lot of damage.
  • Black soldier larvae:  Lucky you! Leave them where you found them.
  • Pill- and sow bugs (roly poly):  We love them and leave them.  They will eat a little from your plants if in your garden. 
  • House flies:  Don’t want them.  Always cover food waste.
  • Grubs:  Great composters, but don’t want them in your veggie garden.
