Yes - all ice melters have the potential to damage plants and hard (stone, paved, concrete, etc.) surfaces. New concrete and boxwoods, in particular, can be damaged by our ice melter products. We are not responsible for any damage to plants or hard surfaces caused by the ice melter. We'll do our best to respect any requests you make about the way we apply the ecosalt (for example, avoiding areas near boxwoods), but if you are more worried about damage from ecosalt than you are about ice buildup, we recommend you go with a no-salt option.
