How to start your own Worm Bin
Starting a worm bin is a simple process that will reward you time and again with something as simple as garden treatment in the form of worm urine, juice, and worm feces, castings, and the worms themselves.
For this setup all you'll need the following;
Worm bin, for this setup we have chosen a tiered system with three tiers, two for the worms themselves and a fourth for the juice.
10L of composted worm food
1000 worms, roughly 1/4kg (minimum recommended)
250ml worm juice
750ml rain water
How to set up and use the bin.
The first layer, starting from the bottom, is the juice catchment tray.
This layer is for the juice, leaving nothing for us to really do once assembled.
The second layer is for our little friends the worms.
In this layer we put the worm food, preferably a compost to help them make a start and give them food to start on, up to the point where the third layer touches it, slightly compacting the middle to allow the worms to transition to the third layer.
Layer 3 is placed on top of layer 2, make sure it touches the contents of layer 2, and is filled with kitchen scraps and inoculated as you put the scraps in. You will find small insects in there, don't worry as many that appear in the bins will be helpful and help break down the larger pieces of food to a size more manageable for the worms.
Using the worm juice and rain water in a ratio of 1:3 using a watering
can pour over the worms and compost as an inoculate . This is also to
moisten the mix more to the worms liking. Remove all the juice from the
1st layer and use up to 2lt back into the bin, the remainder can go into the garden.
Now, filling each layer is pretty simple, inoculate as you go and don't add too much at the same time, as adding too much can cause the food scraps to start to heat up and potentially kill the worms. A guide to adding the food is simple, add the food every few days over one half of the uppermost layer and inoculate using the juice/water mix after adding the scraps, and for the first 5 weeks only add 1lt of scraps. At the end of week 5 you can go up to 1.5tl of scraps a week and at week 10 you can add 2lt of scraps a week.
