Cedar raised bed boxes

Hey folks. Wondering if anyone's investigated this, am I, as I haven't, yet, had the opportunity.

What is the antimicrobial effect of cedar boxes on the soil contained? Does the close proximity of the cedar negatively effect the microbiome?

If anyone has established cedar raised-beds and is also interested, I'd love to have some samples for analysis.

Thanks

Hi J.L.! I used to have a garden full of raised beds made from western red cedar. Here's a picture of them: https://permies.com/t/67972/personal-quest-super-soil#572669

I spent years nurturing and building the soil in those raised beds and I did not experience any detrimental effect of the cedar on the soil contained in those raised beds. The healthiest, most delicious and best looking plants I've ever grown were in those raised beds. I am not a scientist and have not gathered data from tests beds along side control groups, but based on my experience I tend to have my doubts about cedar having a negative effect on the microbiome as a whole in the soil contained in raised beds made from cedar. Hope this helps!

I've had a raised bed of eastern white cedar (6-8" logs)  for a decade or so. Mine is a bit tall at 24" so it seems to dry out a bit more than I would like but I don't think the growth is retarded in that bed compared to the ground. Certainly the stuff around the base of the bed (right up against the logs) grows just fine.
