I want to edge the lawn in a few places and have seen these quite long lengths of coconut wood, which is quite heavy and it's cheap. The guy at the wood yard said it wasn't suitable to be used for what I wanted, but I wonder if a preservative like creosote was used would it be OK?

I've never tried it with creosote but I don't think I would ever bother to try it. Whilst it can be quite long lasting as a lacquered decorative timber, it will break down very quickly if in contact with soil and it is also termites first choice. They love it!

Thanks, I'll have to find an alternative.

Favorite food for termites as mansioned above.

I would be looking at one of the wood substitutes, Shera or similar. In the larger sizes it's remarkably robust and the beasties don't like it.

Think I'm going to go with those big brown bricks, that look like volcanic rock.

That sounds like Laterite, if it's readily available in your area it will do a good job, natural too.
