Planter Construction for the garden


New Member
Hello all, hope you’re all having a good weekend.
Can anyone advise me at all.
I was a plasterer 10 plus years ago and can still chuck a trowel around
Might sound daft but I’m looking to build garden planters out of cement board or something else that will last?
Not looking at using breeze block and render. Is there a board I can use then render?
Any thought well appreciated
