A backyard worm farm may not be the first thing to spring to mind when you're thinking of new garden ideas, but it can be a fantastic addition to any household.
Worm farms are kind to the environment and allow for easy disposal of household waste like food scraps, tea bags and even newspaper! Plus, new designs mean they don't have to be the cumbersome objects they once were.
Follow these instructions to make your own this summer.
A stacked bin worm worm composter is a great option for red compost worms who migrate upwards. They crawl up toward food in the top bin, leaving their castings to fall into the bottom layer. This means the lower bin can be emptied when it is full of castings and then rotated to the top, rather than clearing the entire system.
If you're only planning a small scale operation, three stackable bins should suffice for your backyard. Make sure these are black and opaque as worms hate light and will not thrive in areas where it permeates through their home.
Make sure the bins can nest inside each other. You can use basic plastic storage bins found at supermarkets, however make sure you have a lid for the top bin.
Start with the sump
The sump is the lower bin, and should be prepared first. Its main role is to collect excess fluid leachate and be able to drain this off. Achieve this by fitting the sump with a barrel tap in order to easily empty the fluid without disturbing the rest of the bin.
Stack 'em up
Drill small holes in the bottom and sides of the two upper bins to provide air for the worms. Set the sump on blocks in a shady location, then nest the upper bins within the sump with spacers in between to allow worms to work.
