Used a 12 inch bit. It’s a great workout, but really sucked when we encountered tree roots with it. Tomorrow, I’m going to set some posts in concrete using the holes.

Don’t mean to hi-jack this post but I am getting good advice.
I feel 4’ x 18" hole, for a 20’ (above ground height, so 24’ overall) x 3" pole, backfilled with cement, should be good enough to support 40 lbs of bat house + bats and not worry about winds.
(North of Houston so sometimes tornados, but not the Dorothy going to Oz kind, just little 5 minute ones that blow fences down and the occasional roof.)
Does this give anyone heartburn?
If you were in sandy soil you might end up with issues with wind. Depends how much of a sail the bat house makes. You might end up guying it if it starts to lean.
Thank for taking the time to respond.
It’s not that big, as far as surface area goes and our soil is claylike.
Guying it is a great idea, thank you.
