|Last year I planted a trumpet vine. It looked healthy although the top growth did not develop much, which I expected as I assumed it was establishing its roots. This spring, no top growth occurred at all. I thought the plant was a goner, but now shoots have appeared at the base. I have since read that it is not unusual for trumpet vine to die back during the winter. My question is, is there something I can do to prevent this dieback? I want the trumpet vine to cover a fence, but if it has to start from scratch each year, I doubt this will ever happen. Thanks!
