That is just ignorant.
The chloride WILL leach into the ground around the root crown, and the pressure of the snow getting pushed up on the tree WILL break or tear roots leaving vectors for other issues.
Granted, the Property owner never planned on those trees getting much bigger than they are in the photo, and will likely replace them in a year or two anyway dead or not.
It's still a stoopid practice if it is avoidable.
Good luck with that.Thanks for all the feedback guys. Anyone use these theory's to try to push for snow removal?
Runner,Chlorides ARE used in fertilization, but it s chlorides that are formulated for and dosed for those applications. By these pics, with the type of lot and setting, it could be a highly probable cause of sodium overdose. One factor that would make this unlikely though, is that the islands only hold so much, and are therefore limited with the capacity they can take of added piling of brine filled slush/snow.
A second idea for ya to sell.Good luck with that.
Add up the cost of replacing trees every 3-5 years, and see how it compares to the cost of hauling the slop off over the same time period.
It's likely a wash.
If the groundkeep or service used for maint. is smart, they would be using young potted trees and rotate them out in the fall.
Maybe another avenue for ya...
