All about wicking beds

Wicking beds are a great way to grow vegetables in any area with hot, dry summers where there is competition from larger plants (like big gum trees) that make it all but impossible to establish a vegetable garden in the ground.

Wicking beds work on the same principle as 'self watering’ pots - they are watered from underneath as well as above. The difference is that the reservoir in a wicking bed usually larger and often filled with gravel to help with the wicking action. Wicking beds are often much larger too, offering a viable alternative to standard raised beds for growing your vegetables.

Because the soil in the bed isn't actually in contact with the surrounding soil, you can grow water loving vegetables in places you wouldn't normally be able to - saving space, and integrating yields into established ornamental gardens. You can even grow good yields on top of concrete or underneath gum trees!

If you want to learn how to make one yourself, please see the information videos at the bottom of this page.

What's a converted IBC bed?

IBCs (intermediate bulk containers) are used to freight 1 cubic metre of liquids around the world on container ships. The plastic tub is surrounded by a sturdy steel cage. Reusing IBCs is a great way to reduce waste.

But it can be daunting to buy a whole IBC because you will need an angle grinder to cut through the steel cage and then you need to cut through the plastic and drill your holes in the right places. Cutting through the plastic with a jigsaw, angle grinder (or by hand) also generates a lot of small plastic dust so there's a big clean up operation involved to avoid getting microplastics all over your garden!

To save you the trouble, Mick and Nicole from Maple Garden Wicking Beds can provide ready to use half IBC beds with all fittings. They have been supplying wicking bed kits to Canberra and the surrounding region for over two years. They source food safe IBC containers and all the wicking bed components to kick start your container garden.

Each IBC bed comes with the following:
  • Top or base half of IBC (just over 1 square metre growing space - dimensions are 1.2m long x 1m wide x about 45-50cm high)
  • Silicone used on lids to ensure no leaks (top half only), on the existing IBC tap (bottom half only) and overflow tank fitting (both halves)
  • 5m length of 50mm slotted agi pipe (Australian manufactured)
  • Section of geotextile (we use grey or white UV-stabilised road grade fabric for long life)
  • 50mm pvc inlet pipe with cap and agi pipe fitting (Australian manufactured)
  • One overflow hole with 15mm tank fitting and overflow pipe (Australian manufactured)
  • All sharp edges are filed/chamfered down to ensure safety.

​Important safety note: while they take care to file sharp edges of the steel cages of their IBC beds please be careful when handling!
