This article (www.sail-world.com/cruising/usa/Weedy-seabed-could-have-caused-boat-disaster/93636) makes one wary of anchoring over weed.

I too have experienced cases where I held fine over weed on sand for a couple of days, then suddenly lost grip. Obviously changing wind/swell conditions contributed, but I'm wondering if my anchoring technique or type of anchor also need improvement. I have a plow anchor, which is supposed to be good in weed and sand, which is typically what I encounter.

Short of diving down each and every time and visually inspecting one's anchor, what else would help (apart from finding another more protected spot)?
