My uncle's domestic red currants (red lake) have been in decline for
several years. I have assumed the problem was the deer, but it is
possible it is the weeds. (or both) I am curious to hear others'
experience. He gets random seedlings from time to time, some of which
live for years, although none gets a large as the one I transplanted
into rich soil and keep weeded several years ago. (I had two, planted
close, but the larger one finally overwhelmed the smaller one last
