Worm Towers

Worm tower
We have at least one worm tower in each garden bed.

Worm towers are a handy addition to garden beds. We have one in each of our smaller wicking beds and two in our longer bed.

They’re very simple to make and allow you to add food scraps and green waste directly to the bed where the worms will take care of breaking it down and distributing the goodness.

The size will vary depending on your beds. For our purposes, I used 600mm of 100mm PVC pipe.

The bottom 100mm has lots of holes drilled into it and this layer is put below the soil line. I put it so the bottom of the pipe is 150mm below the soil level. This layer allows the worms to move in and out of the tower and spread their goodness to the soil mix.

The rest is above ground. I put a cap on ours, some folks don’t, but we have rats and other things of the night around that like to feed on veggie scraps.

A month ago, this tower was full. Now’ its in need of a top up of scraps.

What to do

Start the bed by 1/4 filling the tower with worms and castings taken from an active, healthy, worm farm. Add a couple of handfuls of finely chopped kitchen scraps and a little water. Cover the tube.

The the worms will compost the scraps and move from the tower into the surrounding soil for exercise and to lay their eggs. The compost worms won’t live out in the soil, but just sojourn there at their leisure. They’ll return to the tower to eat and live. I’ve added a few earthworms to the beds, just to keep mixing things up a little.

The worm juice and castings will make their way into the surrounding soil and make for happy, happy plants 🌿
