Is there a way to secure a hoop house other then driving posts into the ground?
Or, stated differently: is there a way to get posts into the ground without blindly driving them in?
Yes. Use a wet/dry &quot;shop&quot; vac to dig a hole. If needed, loosen the soil carefully with an appropriate tool (a digging bar, a large screwdriver, a crowbar, etc).
Once you've excavated a hole, set a post in the hole and backfill. The backfill could be native soil, imported sand, concrete, etc. Vibrate the post by thumping it sideways with a mallet or dead blow hammer to help the backfill compact around the post.
