Our crop of stinging nettles has grown exponentially over the past few years, and we covet the bounty. We picked a pound or so today for a batch of nettle wine (recipe to come; same basic procedure as with mint wine) with some extra to dehydrate for tea. Any work in the barnyard brings a troop of helpers.
The goats and sheep keep all greens in the field finely mowed, with the exception of the stinging nettles. Since goats happily munch roses, blackberry brambles, and poison oak, I doubt the stingers deter them, yet they ignore them nonetheless and instead keep them fertilized and without weedy competition.
