Is Bilzen that famous? :p Well I'm not a fan haha; I actually hate it. Those guys have no respect for the rules of the road around here!
Well I already worked in some potting soil and sharp sand through it last summer before planting, but drainage hasn't really improved because of that. Anyway, I'm trying to get my own composting factory up and running to supply myself each year for topdressing.
And yea as you said, mulching is perhaps better in already 'established/planted' beds. I also dig up some worms from the back of the shed and move them to the raised beds to lend a helping hand :p I'd be surprised if they moved from my lawn to the beds themselves as they need to dig underneath the wall.
