Q.Junipers
We have a pointed juniper of the southeast corner and northeast corner of our house. For 3 years the south half of both tree is all brown in the spring. I water them a lot and the brown is better by fall. Should I wrap these trees in the fall to avoid sunburn or whatever the damage is?

Your Junipers are likely suffering from Winter Burn.
You can certainly add some winter protection.
