So I started working in a chemical plant as the lawn keeper. Mainly I mow grass and weedeat. Apparently I also have to take care of the bushes and shrubbery. We'll I took a look at them and alot were choked with vines. I know enough that vines will kill them and it appears they have already. One of them was so chocked that it appeared to be a healthy green bush but once I pulled the vines out it was a skeleton appearing dead. Some of them to appear go have some leaves growing off the branches out the bottom but most just appear dead. Does anyone have some advice. Are they actually dead? Also I have no idea what type of bush shrub they are. Anything will be appreciated

Tried posting photos but it won't let me.
