Soot covered leaves on my Trachelospernum J
I have a trachelospernum jasminoides which is thriving and flowers well but the leaves are covered in what looks like soot. It does rub off but takes quite an effort to remove it. Any ideas what it could be and can I cut the plant right back as it is getting rather large for the space available and this would also remove the unsightly leaves.
