I want to build a terraced garden up a steep slope on my land. I have built raised beds before and just used untreated planks screwed together knowin that after a few seasons I would need to replace them. Not a problem since the rotted wood could be incorporated into the graden. For my current project I do not want to have to rebuild every few years as I will likely néed to include stairs and standing platforms between each level.
I was watching Fixer Upper on home and garden TV and they showed the Shou Sugi Ban technique on wood panelling for a house boat. Does any one know if this would be viable in a garden? I believe it would be non toxic. This would be a garden used for vegetables, fruits, and herbs.
