Warning: I found out the average fence post hole needs way more concrete than I thought

I read a spec sheet from a lumber supplier that said a standard 4x4 post in a 2-foot hole needs a full 60-pound bag of mix, not the half-bag I'd been using. Anyone else run into this and have a good method for mixing on site without a mixer?

Oh man, that's a real bummer. I did the same thing on my last project and had to redo two posts that got wobbly. I just mix it right in the hole with a shovel now, it's messy but it works.

Yeah, the "mix it right in the hole" method @violah43 mentioned is the only way I trust now. It might be a messy job, but it beats having to fix a wobbly post later. That extra minute of mixing saves a ton of time.

I used to mix concrete in a wheelbarrow first (seemed cleaner, you know). But after one fence post started leaning way too soon, I switched to the in-hole method. The mix gets way more solid around the post base, no air pockets. It's a game changer for sure.

Totally agree. Messy beats redoing the whole thing later. A little extra work upfront saves so much hassle.
