Hi Alcuza
To a hog, some nice thick vegetation is nice thick vegetation whether ornamental or not!
It seems quite likely that it was hibernating at this time of year. They don’t normally hibernate in the same places that they used as nests in their active time – apart from anything else for parasite prevention reasons.
Possibly a bit late now, but the best thing to do if you find a hedgehog like that is to disturb it as little as possible, try to replace any of the more surface vegetation which you might have moved and hope it continues hibernating. I think it is a good idea to put some food out, though, in case the hog was hibernating and has woken up. If it wasn’t hibernating it would probably welcome some supplementary food too. Don’t forget water as well.
Good luck. Hope the hog is alright.
