Paul and THC,
Thanks for your replies.
Yep, you are right it def does depend.
But what I am looking for is tolerances, minimums.
I am temperate UK, northern.
Be good to get your input generally before I tell you my intentions. Because I don't want to look at this as an individual case, rather one end of the scale; when planting trees/perens on to unrotted biomass.
As for your pics online. I've viewed these many times. However what would be great is if you have any pics of this bed in production over the years since it was done that would be great also.
cedar does take an extra long time to break down and therefore would be a very slow hugelkultur choice even if it doesn't give off any bad chemicals.
