How can I get my trumpet vine to blossom?
I purchased a trumpet vine a few years ago and planted it alongside a fence which is situated at my property line. The vine grows vigorously every year, but has yet to blossom (the blossoms, according to the label on the plant when I bought it, are supposed to be yellow). I prune the vine back hard early every spring and so far, have never seen a blossom? Your thoughts?
