What do I do with the "dead" looking vines on my morning glories I planted last year?
I planted vining morning glories last year. Very beautiful. This spring they look like dead vines. Do I prune these back or pull them?
Morning glories are an annual, so they live just one year before frost kills them.
So yes, pull them up. You'll porbabhly find that the seeds from last year's flower produce more vines this year. Or you can plant seeds if you want to be sure.
