Clematis problem


My clematis plants appear to be dying part of the vine is brown and crisp other parts of the vine are  green and blooming. What should I do?






Clematis can suffer from a fungal problem that shows up as stem rot and leaf spot and is commonly called “wilt”. The large flowered varieties are most susceptible and often the symptoms include a sudden stem collapse just as the flower buds are about to open, followed by the blackening and drying of a stem. Cut off any parts that are attacked. The plant may recover from buds lower on the stem.

The Master Gardeners of Ontario have some good information about clematis wilt here.
