All about wicking beds
Wicking beds are a great way to grow vegetables in any area where rainfall is intermittent or 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.
A wicking bed looks similar to any other raised garden bed - the difference is that it is waterproof on the base and up the sides. Much like a pond, except that there is an outflow pipe a little way up the side so it doesn't flood if it rains a lot.
Wicking beds work on the same principle as 'self watering pots', which have a reservoir at the base of the pot. The difference is that wicking beds can be any shape and size you want, especially if you make your own, and they have a larger, more effective reservoir inside. If you make your own, they are a lot cheaper than a self watering pot too! Mosquitoes can also be kept to a minimum as you can ensure there's no access for insects, unlike regular self watering pots.
Because the soil in the bed isn't actually in contact with the surrounding soil, you can grow water loving hungry 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! In our garden we have several beds close to a very large gum tree. The tree takes a lot of moisture out of the soil, so only certain plants can thrive. But with the wicking beds we are able to grow heaps of vegetables in the same area!

Converted IBC BedsIBCs 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! (We learned this the hard way! We have now invested in a special set of shears that cuts the plastic without leaving any bits of plastic to clean up - yay!) To save you the trouble, we can provide ready to use half IBC beds with all fittings. Please note we only use food grade IBCs so you can be assured of no nasty chemical residue in your garden bed. Each IBC bed comes with the following:
Important safety note: we take a bit of extra time and do our best to file and hammer down any sharp edges of the steel cages of our IBC beds but we can't guarantee there won't be a few sharp edges left - please be careful when handling! As an extra precaution, we also cut out the middle section of the cage, meaning the plastic insert is higher than the cage, so there are no pointy metal ends sticking up to catch your arm on when reaching into the garden bed. Note that some sellers cut the cage and then turn it upside down - we experimented with this but it results in a much flimsier cage surrounding the bed, especially on top halves. Our approach instead is to retain the strength of the original cage, but cut out the middle section to make it safer for you to work with. This approach does mean it takes a little longer for us to make the beds but we think it's a sturdier and safer bed! PricesTop half - $195 ($210 with tank fitting)

Converted barrel bedsPlastic barrels are used to transport 220 litres of liquid around the world on ships - the blue ones pictured here contained organic soy sauce!
While making these barrels is simpler than an IBC, cutting through the barrels is still a bit of a job and very messy too! To save you time and effort, we cut these in half, drill the holes, make handles with quality rope, and provide all fittings (tank outlet fitting is an optional extra). The resulting bed has a capacity of over 100 litres - about the same as a half wine barrel, but at a considerably lower price! And of course, it's a water wise wicking bed with fittings too. If you're not sure how much you can grow in one, see the picture at the bottom of the page - it's very much about the soil, and as you can see, things really can go gangbusters in wicking barrels! Note: we only use straight sided drums as pictured above. Beds can be a bottom or a top half (the latter have two small sealed bungs in the base). We only use food grade barrels for our wicking beds. Each barrel bed comes with the following:
