How to build a wicking garden bed?

Hello Bunnings community, I am after some advice on wicking garden beds. I am following the steps on the Bunnings website https://www.bunnings.com.au/diy-advice/garden/planting-and-growing/how-to-build-a-wicking-bed

I’m unsure as to what size (diameter) agri hose to buy and what size drill I have to make on the bed for the outlet. I’m also bit unsure about how 19mm poly joiner connects with agri hose. Any advice would be appreciated. Any photos would also be great! Thanks, Praveen

Hello @prav21ooty

Thanks for sharing your question about building a wicking bed for your garden. The guide recommends using 50mm PVC fittings but the smallest agi pipe with a sock filter is 65mm. I recommend going to your nearest store and testing the fittings together to make sure that they work. There are larger 65mm fittings just in case the 50mm piece is too small.

The instructions state that you need to cut a hole in the side of the garden bed and attach the poly joiner. This is technically the overflow hole of the bed and prevents you from overfilling the wicking bed with water. The suggestion is that it sits just above the level of the scoria. The poly joiner is not connected to the agi hose.

If you have any other questions we can help with, please let us know.
