Wood preservatives

[gdh]

I'm about to build some raised beds for the garden and what wondering what treatments others use for wood? Is creosote still any good?

 

We're going to cut the wood here from sequoia and I'll need a lot.

It's not as good as it used to be because the process they used to do to make it at coal mines isn't done the same way anymore I believe. You can get a full barrel of it and then soak the wood in it for best effect. It's what we do for fence posts.

Add some burst oil to the creosote

Thanks for the advice so far. Nice to know you can still get proper creosote.

 

Any alternatives for vegetable beds, I've been told nothing too poisonous.

just use a wood that is resistant to rot...

 

both wester red and genuine cedar will do the job. 15-25 years.

That would be ideal but I can get hold of sequoia/redwood reasonably priced and I'm aiming for the beds to last 20 years.

 

Edit: are we using different names for the same wood here?

all different woods mate.

 

western red, Western Red Cedar | The Wood Database - Lumber Identification (Softwoods)

 

sequoia, Redwood | The Wood Database - Lumber Identification (Softwoods)

 

cedar, Cedar of Lebanon | The Wood Database - Lumber Identification (Softwoods)

 

 

there are loads of other timbers that do the job too.

 

 

these are on ebay and could be of use.

here is a chart that may help you.

Sequoia is a good choice for raised beds isn't it? Rated as moderately to very durable depending where it's grown.

If I were making the beds I would use Sequoia with no treatment and expect it to last upwards of 15 years.

Maybe I'm wrong but I reckon if Sequoia is at hand then it's a good choice.

yes james it is an excellent choice.

 

you don't have to go all exotic to get good rot resistant timbers.

 

home grown ones can include robinia, oak, sweet chestnut, larch, any of the three cedar (cedrus) species, western red cedar, leylandii and im sure that there are others.
