I recently salvaged some Redwood deck lumber from my parents home. After 25 to 30 years, the board ends had started to rot out (where the boards had been nailed), but a lot of that lumber is still useable.
I am thinking about using some of those boards to edge my garden area and raised beds.
Does anyone know if Redwood boards were ever chemically treated? Or, would it be pretty safe to assume those boards were untreated, since Redwood is supposed to be naturally rot-resistant?
