), the asparagus beetle, which can infest (check with Google Image, they're quite vivid). There are both organic and inorganic sprays to combat them but for most garden beds picking them off by hand and 'despatching' is more common and an adequate deterrent (the grubs will over-winter in the soil and set up a cycle that's harder to combat so the trick is to get them early!) A friend (who grows better asparagus than me, grrr) always allows ONE plant to go straight to fern (i.e doesn't crop that one at all, different one each year) to act as a lure on the basis that any asparagus beetle turning up on the bed will naturally go for the easiest option. He then inspects that plant every day (or so) during the cropping season and removes any beetles he finds. Seems to work. Happy munching. b.
