Raised wicking garden bed with Ekodeck

An elevated garden bed clad with Ekodeck and lined to create a self-watering wicking bed.





The project

This is beneath the window of what will be our master bedroom with Gardenia planted in it. The bed itself is an elevated timber frame and then it's lined to create a self-watering wicking bed.


The whole garden bed has then been clad with 137mm EkoDeck Plus decking slats, which have concealed fixings. As a lot of what I was attaching to was steel I used their fixing kit for steel joists.

I have used EkoDeck before on smaller screening projects so this one was interesting to do and pushed the limits a bit. To give neat corners I used aluminium angle, some of which I had to paint myself as I couldn't find larger sizes in a black finish. For the edging along the top I found that HardieDeck trim worked but I did need to plane the boards a little as it is designed for 18mm boards and the larger EkoDeck is 23mm.


To get the best lifespan from a project like this, you really need to use a landscape-grade timber for the internals especially. Ideally use H4 treated pine. I tend to use sleepers for these projects as they are cost effective, easy to work with and have a long lifespan. Normally 200 x 50mm x 2.4m does the job.


Any screws need to be suitable for landscape use too. You can use galvanised but personally I prefer ClimaCote as I've found that they are a lot easier to screw in and apparently they have a longer lifespan in treated Pine.
