This week we’re talking about worm farms, and the huge capacity of worms to turn “waste” food into a rich source of nutrients for your fruit trees.
It’s the single best thing you can do at home to provide high-quality fertiliser for your fruit trees.
You may not appreciate just how awesome these tiny creatures are, but they are truly incredible waste-munching machines, and a worm farm is one of the simplest and most useful things you can add to your garden to rapidly increase soil fertility with absolutely no cost.
Do you have a worm farm? And if not, why not?
Lots of people think it’s complicated, messy or expensive to set one up, but it doesn’t have to be – there’s no need to buy a ready-made worm farm.
Or you might have tried to have a worm farm but ended up with a pile of sludge, or all the worms either died or mysteriously disappeared – all common problems, but simple to avoid when you know what worms like!
So, here’s the 7 steps to make a simple and inexpensive worm farm at home that will provide the right habitat to keep your worms happy.
- Get a suitable box – a simple polystyrene box with a lid will do, and you can probably get one from your local organic or fruit and veg shop, or possibly even the supermarket if you don’t have a greengrocer nearby. Put a drainage hole in the bottom if there isn’t one.
- Line the bottom of the box with some appropriate bedding material.
- Wet thoroughly – it should be about 10 cm deep in total.
- Add a handful of compost worms (note: don’t use earthworms, as they have different feeding habits and won’t be happy in a worm farm).
- Put the lid on the box (pierce a few air holes in it first), and keep your worm farm in a spot with an even temperature – not too hot or cold, and not in direct sun.
- Feed the worms regularly, but not too often (be guided by how quickly they are eating the food you’re giving them), and make sure they don’t dry out.
- Dampen them every few days if they seem too dry, and collect any excess liquid that drains out the hole in the bottom. This is worm juice, and is fantastic liquid fertiiser that you can dilute and use on your garden. Worms don’t naturally produce liquid, so you’ll only get this worm juice coming out of the worm farm if there’s an excess of liquid going in, but be careful not to add too much water (and make sure the drainage is adequate) or you can actually drown your worms.
As long as you’re fussy about details like appropriate bedding materials, adding the right type of worms, and feeding them the good stuff you’ll now have a super-powered fertiliser machine in your garden.

And then sit back and enjoy the lovely “black gold” your worms produce – the finest compost/soil conditioner you’ll ever see!
