Hello all. I was hoping to get some help with my Bower Vines. The vines are in large planters, a couple feet deep, and they have grown about 12 feet high up my stucco wall. However, they are thinning out, with some vines leaves turning brown, followed by the stem turning brown/black. Is this normal? Check out the pictures. Thanks!!
