Wax leaf ligustrum
We had a week and a half cold snap ( got down to -3) and now all the leaves on my ligstrums turned brown and many/ most have dropped off. What should I do? I have over 400 of them in a rather long privacy hedge. Can I save them?
There is not much that needs to be done now. You can cut the branches back a little bit after the weather warms back up some, but other than that it will recover on its own just fine.
Here is an article for more information on the shrub: https://www.gardeningknowhow.com/ornamental/shrubs/ligustrum/growing-ligustrum-shrubs.htm
