My uncle told me to always set posts in the rain, and I finally tried it on a job in Portland last month.
He's been putting up fences for 40 years and always said the rain packs the dirt tighter around the post, making it stronger. I thought it sounded like an old wives' tale, honestly. We had a big privacy fence job with 40 cedar posts, and a steady drizzle started right as we were about to set the first one. Instead of waiting, we just went for it. Mixed the concrete like normal and dropped the posts in. The mud was a pain, but the ground was so soft it made digging and tamping way easier. A week later, I came back to check and those posts felt rock solid, like they were part of the earth. Has anyone else tried this, or was I just lucky with the soil type?
