How to Create a Wormery for Garden Compost


Wormeries are a simple way to compost kitchen scraps for your garden. This method will allow you to compost the leftover food of three to six people. Of course, you can make larger or smaller wormeries. A good rule of thumb to remember is that 2 pounds of worms can go through about 1 pound of scraps per day. Scraps can include any biodegradable items that are free from chemicals, such as pesticides.

Step 1

Drill 14 to 20 holes on the bottom of the plastic bin. If using wood, drill fewer holes, only 9 to 12. Drill two holes on each side of the bin, just below the lid.

Step 2

Place bin on bricks or blocks, over the tray. Fill the bin about halfway up with shredded newspaper. Add dry leaves and mix together.

Step 3

Put in two handfuls of peat moss and one handful of sand on top of the mix. Add a handful of crushed egg shells.

Step 4

Water generously. Place worms on top of mixture. They will burrow in.

Step 5

Add food scraps. Cover wormery and keep in cool location, never in direct sunlight. Feed again when food is almost gone.

Step 6

Harvest compost three to four months later by placing wormery contents on an open newspaper. Create small piles around the edges and allow worms to crawl out and to the center. Now you can use the compost in your garden.

Step 7

Repeat steps two through six as needed to create more bedding for the worms.

Tips and Warnings

  • Only use black and white newspaper, not the glossy or colored sections.
