Wood preservative for a planter

[Chief Broom]

I intend to make a large ,tall and deep planter for a climbing rose. Decay of the wood is inevitable but thought i might treat the wood with something to slow it up. Question is whats best and wont be toxic to the rose?

I'd treat it with something like sikkens then line with thick plastic.

I'd get a plastic pot and build the planter round it.

inside or outside the planter??.....on the inside of my planters i have painted them with cuprinol ducksback in black with the new wax formula and also lined them with the thick black rubble bags, so the timber doesn't suck the moisture out of the compost

Both i want it to last as long as possible and when its cream crackered i will make a new one around it....unless im dead of course then my only employment will be pushing up the Bellis perennis

all mine are the same black cuprinol in ducks back inside and out.......i use black as it allows the flowers to stand out against the darker timber

There are numerous products which claim to be non toxic to plants. If you're going to use one I suggest a well-known brand such as Cuprinol, Ronseal, Sika. Myself I wouldn't use anything but would line the plant, pop the rose in a container and fill any gap with stone of some type.

Use the right wood. Larch will last fifteen years untreated.
Sweet chestnut will last thirty.
Slapping chemicals on wood to preserve it is just slapping chemicals around.

Some of those woods are expensive though and cant always be bought locally……..

You do love the sound of your own voice mate. Seems you have to chip in with opinions on opinions. You had your say. Let someone else have a shot.

Just making an alternative, sustainable and environmentally sound suggestion to the OP, based on thirty years in forestry and as a mobile sawmill contractor.

Aside from arsenic-based and petrochemical preservatives, you may as well pour your money down the drain protecting softwood with proprietary "preservatives".

So you believe your opinion cant be challenged - hmmmmm, yet your challenging mine and being abusive at the same time…….

the only thing is im pointing that alternatives can be expensive and maybe not locally sourced. Maybe we let the OP decide

I used yacht varnish on mine. Quite pricey but if you don't mind the yellowish colour then it'll protect very well with 2 or 3 coats

I would like to use a type of wood that would last but making the best of what ive got. I found a load of timber in the attic of the house i just moved into. I think its all pine- kids bunk beds and frame of an adults bed and various dismantled cupboards-this is what im using. If a preservative isnt going to extend the life much i'll use it as it is.
Bodged a cold frame today just need to do the top

No you must go and buy rot proof red cedar…….enjoy the planter

At the very least, keep the base of the planter off the surface that it sits on.
