Help with Star jasmine
I am really hoping for some advice for my Star jasmine, which is kept in an unheated conservatory, in good light. It had a great summer last year, flowering well and putting out lots of 'runners' which I hoped would start to wind their way up a trellis. It overwintered in here, which is frost free (no less than 5C). I noticed quite a bit of scale, so treated initially with Provado, and more recently with several applications of horticultural oil. All the scale I can now find appear dead and just flake right off.
As you can see, the plant looks awful and on death's door. Lots of browning leaves, many of which fall off to the touch, and a complete wilted look. The compost is not dry so confident it isn't as simple as that. I assume this isn't normal for this plant at this time of year, prior to new growth? Any help much appreciated.
