How To Build Your Own DIY Worm Tower

Do you always kill your worms? Then try worm farming with our easy DIY worm tower!

Today we want to share our really easy How to Make Your Own Worm Tower video. In just a few minutes you will learn how to make your very own DIY worm tower. And the great news is it can be made from scrap materials.

When you farm worms in the ground with one of these worm towers they are much less susceptible to heat stress, which is the number one killer for worms.

Furthermore, with this tower your worms will come and go from your garden beds, spreading their castings for you as they go.

What you will need:

  • Offcut of PVC pipe
  • Drill
  • Suitable cap for PVC pipe

And that’s it! Follow along with the video above to see how easy it is to create your own DIY worm tower.

The plans for this worm tower are featured in Issue #10 of Pip Magazine, available here.

  1. We have a large open container 1.5×1.5m which we’ve used for composting and have introduced worms. We’re a little worried tha our worms are dying, that they’re too susceptible to heat stress vs being directly in the ground.

    Lots of other small bugs etc are doing a great job of composting but haven’t seen worms for a while.

    Any advice to keep them cool in the weather’s warm weather?

    1. I recommend layering up more matter on top – prunings, grass cuttings etc. At least 1 foot deep. See how that goes. If they are nice and deep they can have their pick of which soil depth they hang out i to ensure their survival. This worm tower idea might suit you if you are good at killing them because they have the same level of control over their own environment, temperature and needs to survive.

    2. HI Alicia,
      Thanks for your question. Worms need to be in a temperate (up to 25c or so) and moist environment as they rely on the moisture to move around. If they are too hot or dry they will go as deep as they can to try and find moisture. A few suggestions; The worms (and the food scraps) need to be well covered as the worms are adverse to light. I use straw or newspaper/cardboard which I wet thoroughly first, I also put a cover over the whole thing to create shade and protection. I like old carpet or hessian bags as they allow the moisture in when it does rain or when I hose it. Another option is tin or wood but either way, you need to remember to check the moisture. Too wet and they’ll drown (but I don’t think that’ll happen in a bin that size), but too dry and they’ll disappear. If you want to see if the worms are still around and encourage them back, moisten the whole bin (so they can travel easily), perhaps turning it a bit, then crack a few eggs or add rich food scraps in one place and again, cover with a moist covering. The worms should come to that place within 24 hours. The most important thing is adequate moisture in the whole environment and protective covering over the food. The other option is a separate worm farm just for food scraps where you can monitor the worms a bit easier, I use an old bathtub. I hope this helps, Peta

  2. Great post but SO ugly! There are more attractive options. I have one made from an upturned length of terracotta pipe (old sewer pipe) with a terracotta dish on top filled with water for the local birds. When I have worm food (scraps) I tip the old water into the pipe and add the food. Then I refill the bird bath. The whole thing looks really beautiful.
    I also have one made from a plastic bin with a fitted lid. This has large holes drilled in the bottom and tiny holes drilled in the lid for drainage and ventilation. It’s half buried under my avocado tree (gross feeder) and uses both resident compost worms and visiting earth worms to nourish the tree. It’s in an area where we entertain so food waste from parties can go straight into the worm hotel.

    1. Does the terracotta pipe need to have holes in the sides under the ground or do the works just climb on up through the bottom?

      Also do have a design for your worm bath? We are thinking of starting a micro business in worm juice for an autistic gentleman I work with to get more active in the local community ????

      1. Hi Paul,
        Thanks for your questions. Firstly yes. If you want the worms to go out the sides they will need holes, but that can be pretty tricky with terracotta. One could have the PVC pipe with side holes in the ground and fit a terracotta pipe into or over the plastic to make the whole thing more aesthetic? That would be one way to resolve both issues.
        Secondly, nice idea to start a micro-business with worm juice. It’s very simple. Get an old bath or series of deep laundry tubs (check the local tip shop regularly). Your worm farm will need to be elevated for a couple of reasons: 1) To make it ergonomic 2) to enable a bucket or container to fit easily under the drain to collect the worm juice. I like to put a bottom layer of blue metal or small pebbles to ensure that you always have good drainage and then I put some shade cloth straw on top of that. Then begin to make your worm farm with damp organic matter, some food scraps or manure, worm stock and then damp organic matter over the top. I keep my farms covered with old carpet or a lid of some description to help prevent drying out. I like the carpet/thick material so if we do have rain, the whole farm is moistened but excess moisture will drain out. If you live in a very wet area, use a sheet of corrugated iron or ply to help keep things evenly damp so the worms don’t drown. Good luck with your venture! Peta

  3. Here is a another way of building one and useful tips on household composting. They can be made attractive to blend in to the garden. I have also made a larger version out of a 200 litre drum.The first one I made for my neighbour did not seam to work until I put a damp sack over it befor putting on the lid … and hey presto the worms started munching. It can be messy pulling up a damp sack so I have installed a little ‘pillow’ made of shade cloth stuffed with some insulating cloth and added a handle of used polly pipe. It fits snugly into the top and keeps in snug for the worms.
