Is there a selective weedkiler to spray trees that are entwined in Jasmine that will kill the Jasmine but not the trees?

Hi Anthony, Unfortunately there is no easy way to deal with pest vines growing in trees. The best way to deal with these vines is to cut the vines at the base as best as you can and leave the foliage in the trees to die off. Spray a weedkiller such as Yates Amitrole (a weed killer for hard to kill weeds) where the vines are growing at the base. You will need to keep a spray routine to make sure the vine doesn’t grow back again. They can be extremely resilient as you probably know.
