morning glory - cut back or not ?
hi - my morning glory always looks like this (click link below) after winter but there is normally life running through it and it becomes completely full again in spring. however, we had a colder winter than usual and the only signs of life are in the runners next to the ground. someone suggested that i could just leave the dead vine for the new growth to climb on. would this be best or should i just cut all the dead back and start all over ? any green in the photo is from other plant life. - thanks, brian
