I can add that I have had beds both of wood and without. The wooden one are ok but yes they do make it easier for the pests to hide and if your paths are a bit rough (such as mine are) then the weeds can also wriggle their way through. I had mine for 15 years and I’m now slowly getting rid of the wooden beds and just mounding them up gently.
I’ve seen Charles’ gardens first hand and they are exceptional, I aspire to this!!
