The finished ‘WoodblocX’ planter- soon to be home to an alpine collection
You may recall that two wooden planters in the courtyard here at Old School Garden, recently ‘bit the dust’. Not using pressure treated timber when I made these a few years ago was certainly a mistake. I was wondering what to do to replace them and a few weeks ago was approached by a Scottish company called WoodblocX to do a trial of their products- they make a range of raised planters, beds and ground support systems using an interlinking set of wooden bricks (or ‘blocX’).
Having looked at their comprehensive website, I decided to go for a raised planter (1350mm long by 450mm wide and 450mm high), and I’m hoping to use this both to replace the old planters and create a new feature – an alpine bed. This should be at the right height to be viewed from the nearby metal table and chairs in the courtyard and if suitably finished off will tie in nicely to the predominantly black and terracotta colouring of the many other planters and pots in this sheltered, sun trap setting.
Well, the planter was successfully delivered within a few days of ordering. Last week (having given the courtyard surfacing its yearly clean), I set about constructing it.

- In with the new- my new ‘Woodblockx’ planter awaiting construction
There was a pack of various leaflets and other material supplied with the pallet-load of parts and having checked these off against the list supplied, I wound myself through this material. Though comprehensive, the fact that there were bits of advice and information spread across more than one document initially threw me and I didn’t find any instructions specifically about how my planter should be built or look.
So I spent a few minutes working back from the diagram on the company website to see how each layer of the planter should be built up. I also began knocking in the various plastic dowels and wedges (which join each layer of ‘blocX’ together) to what I hoped was the correct configuration. Then I discovered that these didn’t match up to the next layer’s holes, as the next layer of blocX has to be laid like a brick course with no joints overlapping each other, so not all of the holes correlate. Still no problem, as I guessed that a couple of spare blocX had been sent and, as I discovered later, it is easy to just saw off the tops af any dowels that are in the wrong place! (there was also a good supply of plastic dowels sent so I could afford to waste a couple).
I decided to take another look at the literature I’d been sent and then – to my embarrassment – discovered a set of instruction diagrams for my planter showing which sized blocX should go where and which holes should have the dowels in! Though I hadn’t worked out the layout to exactly match that shown in these diagrams, I thought mine would work too, so I pressed on with the second and subsequent layers. Hammering in the dowels and then pushing home the next layer of blocX on top was very satisfying and I proceeded layer upon layer, to see my planter taking solid form before my eyes!

- Using a rubber mallet, and green plastic tubing to hammer home the black plastic dowels was a doddle
After the fourth and final layer of blocX then came the simple, but attractive capping, which really finished of the planter very tidily. This is knocked onto another set of dowels as well as four metal corner brackets which help the planter to hold its shape. The whole construction time- allowing for my careless beginning– took around an hour, was simple and good fun, giving ‘instant results’.
These planters can be used in open ground (they come with two long metal spikes which help anchor it into the ground), but in my situation, sat on clay paviours, the weight of the planter (especially once full of earth) will be sufficient to hold it in place. As advised by the Company I could have also fixed it in place with some angle brackets. I will add an inner lining of landscaping fabric to help protect the wood (though it is all pressure treated) and to avoid soil seeping out from underneath.
Though the rough-planed finish of the WoodblocX is attractive enough from a distance, I think I may sand it down a little and apply either some black wood stain or similar treatment to tie it into the rest of the courtyard planters. I’ll do a further article to show the finished item, planted up.
