Q.cold damaged jasmine
Is it possible to save a Jasmine plant that has brown leaves from the cold? My Jasmine plant was hit hard by cold and snow. It’s not completely brown, maybe one third of the leaves. Will fertilizer help and, if so, what type?

You can prune away the dead or damaged plant material.
Do not try to fertilize it into health when it is stressed.
Wait to fertilize when the plant is actively growing again.
