How to start and maintain a worm farm


I trust you are well. It's about time to get the next worm composting newsletter out.

Today we will help all those who are new to worm composting with a crash course in worm farm set up and maintenance.

There might as well be some useful information for the experienced worm farmers.

So lets get into it right away.

Starting a worm farm to convert organic waste into nutrient rich plant food and soil conditioner!


This newsletter will give you step by step instructions how to set up and maintain a 3 tier worm bin.


1.Find a place out of direct sunlight for your Worm bin to prevent overheating.


2. Place a layer of approximately10 cm / 4 inches of moist bedding in the bottom of your Middle Bin.

As bedding you could use Shredded News Paper or Cardboard.

The bedding should be soaked in water for at least one hour and then drained before you add it to the worm farm.


3. Place the worms with some soil or compost on top of the Shredded paper.

Your worms will burrow down into the bedding.


4. Start adding worm food in small quantities at first. Increase feeding with time.

Place the worm food on top of the bedding and cover it up with a whole soaked Newspaper and a plastic sheet, this will act as an barrier against pests and keep the moisture levels more stable inside the worm bin.


5. The Contents of the worm bin should always be moist.

If the bedding seems to become dry, pour some water (a few liters / half a gallon) over the food and bedding but if possible avoid fresh tap water that contains chlorine!

Let water with chlorine stand in an open bucket for 24 hours. This will help to reduce the chlorine level in the water.

The bedding should ideally be as moist as a squeezed out sponge.

A little more or less will still be fine.

(Worms are breathing through their skin and need a moist environment to breath)


6. In regular intervals remove the plastic sheet and newspaper and add fresh food onto the surface of the Middle bin.

Compost worms are top feeders and will always

migrate upwards to follow the food supply

Once the middle bin is full start adding food to the bin on top of it,

over a period of time most of the

worms will migrate upwards into the top bin


7. Regularly add some water to your worm bin to adjust the moisture level.

The bedding and remaining food in the bin will soak up the moisture level it can hold.

The excess liquid will absorb nutrients from the finished worm castings in the bin and will drain into the bottom bin (It should ideally have a Tap)

You can harvest the liquid and either use as is or brew some fresh Worm tea with it.


8. When the top bin is about half full with worm castings and food most of the compost worms should now be in the top bin.

Now harvest the worm castings from the middle bin

Empty the worm castings from the middle bin and place the empty bin on top of the half full bin that is now containing the worms

One of the advantages of a 3 tier worm bin is the fact that you don’t have to separate the compost worms from the worm castings manually


It is important to know that compost worms of the variety Eisenia fetida can handle a wide range of Temperatures from about 5 degrees C /41 degrees Fahrenheit to 28 degrees C / 82 degrees Fahrenheit quite comfortably.

If you follow these simple steps you should be off to a great start with your worm bin and should have lots of fun with your worms for years to come.
