i have recently recieved two jasmine plants - im not sure what type they are, they are growing around a looped wire and have small white buds. they were close to being thrown out from the shop that sold them. i have repotted them, which desperately needed doing, watered them and put them in a sunny position. there is still quite a bit of green on them, but a lot of dead bits also. does anyone know how i can save them?

thanks
