Help there any treatment for my Jasmine Officinale? It's in a pot and the leaves are covered with black sooty sticky stuff l have been cutting the effected leaves out but there are SO many, l would hate to loose it.



You'd need to tackle the problem first. Aphids ? Mealy bug ? Scale ? is the jasmine indoors or out?

Usually, a wipe of the leaves with a squirt of Fairy liquid in water does the trick. Bit more info needed.

The black sticky stuff is almost certainly sooty mould and it grows on the honeydew secreted by insect pests. If there is a lot of the black stuff then there is (has been) an insect infestation which you need to cure.
You can go for the napalm-in-the-morning approach and spray with a branded pesticide (but please avoid anything with neonicitinoids) or you can spray with a mild soap (not detergent) solution.
Make sure you spray the whole plant, especially the undersides of the leaves.
You may need to spray more than once.
