Two years ago, I planted the Autumn Revolutions cultivar of bittersweet near a garden trellis. The vines took over the trellis quite nicely, but it has not fruited.
I know most varieties of bittersweet require both a male and female plant to produce fruit, but this cultivar is supposed to have both male and female parts on the same plant, and thus be self-fertile.
I did try to plant two separate vines on either side of the trellis, but only one thrived. I have not seen any flowers on the established plant either year.
I am about to re-plant the second vine, but was wondering if I there is anything else I can do to encourage fruit production on the established plant.
Perhaps the plant I purchased was faulty and did not actually have both the male and female parts?
