I am building a long rectangular wooden planter with a trellis back to be sited on top of a wall. The wood has been preserved. Do I need to line the box with something like pond liner and/or do I need to drill drainage holes in the bottom of the planter. It is approx 18" high x 12" deep and 9' long.



I highly recommend lining the box, just to prevent the wood rotting so it stays looking nice. Yes I would also drill drainage holes, I have on my planters so they don't stay bogged with water.
Love the name btw :o)
And welcome to GOY

welcome to Goy L plates. I agree with busy bee. How high is the wall on which you are planningto site it. It could probably do with being lifted on feet like you would do with a pot to allow water to drain.

I would suggest instead of lining it with plastic you find a plastic container that fits it much easier to manage as you can cover the drainage hole so they dont clog and the roots wont puncture.

Good thinking Drc726. That will also allow excess water to drain off.
