I have four old raised garden beds made out of wooden 4x4s. I never stained or sealed them or did anything to them (except garden in them). Now I want to pay some attention to them. Is it too late? What can I do?
They were put in maybe 4 or 5 years ago. I don't know if they're treated or untreated, but if that's important information I can try to figure it out (how?). They're definitely weather-worn but still intact and sturdy. I want to (1) make them look nicer and (2) help them last longer. Assume I know very little about what I'm doing, though I have stained furniture before. What can I do?
