Planter made from decking

shanyajayatilaka

hi, my husband has just made a massive planter made from decking board wood. Should I line this with plastic before use? Would lining with cardboard be sufficient ? ( his suggestion now mine) 

any advice please ? Thank you!

I would imagine that cardboard might help retain moisture but it won’t protect the planter from rotting.  I would use plastic.

You do need drainage holes both in the wood and plastic at the bottom.
Impressive bit of woodwork, its going to take a lot of mpc + Ji3 to fill.
(Multi purpose compost and John Innes no 3)

Thank you! My husband loves a project! 

Any advice on the plastic used to line it ? I have to find some and also a staple gun! [email protected] garden shop maybe 🤔!

Thanks , this is what I thought as well! Would be a shame for it. It to last as long as possible after all the hard work that went into it !

Old compost bags are perfect, so whatever you can get of that sort of thickness if you haven't any.

You can use anything tough, old compost bags, pond liner, old tarpaulin. 
If you are buying in compost in bags use those if you have somewhere to tip it.
You can buy nails with a broad head meant for nailing shed roof covering which would work if you don't have a staple gun or the copper sort for slate roof tiles

Sorry to trouble you again! Would weed control fabric do the trick at all? That way water can pass through as well ?

I think the idea for the sides is to stop water but for the bottom you need drainage.so even with weed membrane you will need some holes in the base.
Your container will last a few years even without a plastic liner, then your husband can put his skills to use and make you another. 😁
