Question
I have a jasmine in my London garden which has been happily in situ for 12 years. It flowers profusely and is a vigorous grower, particularly in the summer. This year, however, the bark is splitting like it has exploded. There is still lots of new growth but some parts are dead. We had some very cold weather this winter and had lying snow for over a week at a time and the jasmine was covered in snow. I'm wondering whether it has suffered from the cold, or whether it has a more sinister disease.

Hello and good morning from Arkansas.  I am glad to hear from a visitor from afar!  Bark splitting can be a result of freezing temperatures.  Best to protect from forcasted cold temps if feasible or practical.  After the cold period and plant has resumed growth, you can selectively prune out the dead portions that may harbor insects or diseases.  Be cureful to stay away from the "green parts" though. Just dispose of the dead prunings. Also be sure to keep it watered to avoid drought situations.

Thanks for your interest!
