Brassicas are not a good choice in high deer density areas, even in a good year with adequate moisture. I’ve noticed they’ll browse them down to having no above ground foliage at all in very short order. The plots we planted in high percentage cereal grains and clovers are being browsed, but they’ll be ok. We’ll get rain in 10-14 days and they’ll rebound quickly. I don’t expect my brassicas plots to come back. The damage has been done.
