I can believe that.
I used to come home once in awhile from the hay sales down a certain side road, guy had a row of arborvitae planted along the road around a curve, looked real nice. They never used to salt that road or curve, ever. The last 4 or 5 years they’ve kept it clear all winter and I’ve noticed his trees are looking sick last time I was by. Sure wish all that salt would slow the grass down in the ditches along my yard, that stuff grows thick and heavy all the time.
