Hedge is Dying
 

I have a hedge in my front garden that I planted last year and just in the last 2 weeks about half of them seem to be dying. I don't even know the name of the hedge to search for an answer. Anyone have any ideas? Am I over watering or not watering enough? :(

Could be the soil ph.

Indeed, but before concluding that you need to know for sure. For that people usually hire a specialist or do the test by yourself. You'll need a special device like soil tester of some sort, something like this https://bumpercroptimes.com/best-soil-ph-testers/. Only after that, you can apply fertilizers and weed killers from local store but read the label carefully.
