Wilting asparagus problem

Ah - me too! This is my first year of growing asparagus. I planted them last year and they ferned up; then this year, I think it was the first one showing that stayed bent over and then did nothing. I thought I saw a brown mark at the bottom of the stem but that wasn't necessarily slug or snail damage. It has been a funny spring and lots of cold winds too. I have erected a piece of horizontal cleamtis netting about a foot over the spears and will put another one about 3 foot above so that the spears/ferns aren't broken by the winds as we live in an exposed situation; but the bed is protected by pallets to about 3 foot on three sides.
