Over watering escallonia pink princess hedge.
My neighbor has been watering his lawn almost non-stop for several weeks even though it's February, and we live on the central Oregon coast. His sprinklers also water my escallonia pink princess hedge to the point that the soil is soggy all the time. Is this harmful to the hedge? If we get a frost will this soggy soil increase the danger to the hedge?
Unless you are seeing signs of rot, like spotting and excessive leaf drop, I don't think it will cause it much harm. You can add wettable sulfur to the soil to prevent any infection from starting. Plus, sulfur is good for the soil regardless, so adding it would be a good thing to do anyways.
