Could anyone tell me what is wrong with my Star Jasmine. The leaves are turning brown and falling off, even the small amount of new growth it has put on has turned brown. I bought it two and a half years ago, and its in a large pot against a wall where it is sheltered from harsh winds.I feed it fortnightly in the spring with Tomorite which usually encourages it to put on lots of new growth.but nothing i do seems to be working, its looking a very sorry site.It has always looked very healthy up until this Spring. do you think its the awful weather we have been having that has caused this. Have uploaded a couple of pics.for you to see. Any advice would be apreciated, many thanks Elizabeth.
