Does anyone here have any knowledge of, or know of resources to find out if calcium chloride (i.e. highway de-icing) has adverse effects on juniper, specifically Juniperus virginiana and/or J. chinensis? We planted a row of J. virginiana late last summer along a busy road. We chose redcedar because of its hardiness against drought, salt, pollution, etc. but this spring all 18 of them died! I called my wholesaler in a panic and he told me that the extra that he had ordered when he ordered mine were also dead (the nursery is an hour and half away and a USDA zone warmer than me). He was unable to get an explanation from his supplier/grower and we have all assumed or agreed that the problem was from the grower. After much consideration as to possible causes, we've started to wonder if the use of calcium chloride as a de-icing agent on the roads may have been a contributing factor? Thus we are concerned about the health of the newly planted shrubs (J. chinensis). Any thoughts would be greatly appreciated.
