No diggers just cover with composted mulch, there’s nothing for the slugs t & wood lice to eat so they b@gger orf. The worms dig it for you & all the micro organisms get to do their stuff without being disturbed
Are you saying that you think, dug/forked over soil plus a covering of compost or manure, provide more food for slugs and wood lice, than the same thing on undug soil?
The worms & micro organisms also do their stuff under my covers, as well.
