I just returned from a two week trip during which I, against my better judgment, entrusted my in-laws with the care of my garden. I returned to everything still (mostly) intact, but with wood chips all over my beds. My brother in law is obsessed with these chips and are all over his gardens. I personally despise them (and have told him that on many occasions). I guess I just want someone else's opinion, partially as defense to him when I dig them out: is there a problem with these being in my vegetable garden?
