Salts utilized to melt ice by lowering the freezing point of water below 32 degrees, de-icing materials are very popular among landscape superintendents throughout the northeast and Midwest.

De-icing salts damage landscape plants when excessive amounts accumulate in the soil, with the most serious damage typically occurring near major streets and highways where salt from run-off accumulate.

Before applying salt, wait until the precipitation has ended and remove as much of the ice and snow as possible. Mix salt with an abrasive material. Fifty pounds of sand mixed with one pound of salt works effectively. Avoid piling salt-laden snow and ice around trees and shrubs.

As soon as the ground thaws in early spring, heavily water areas where salt accumulates over winter. A thorough soaking should help flush the salt from the plant’s root zone.

If possible, alter the drainage pattern so winter run-off drains away from ornamental plants. When planting trees near major streets or highways, consider selecting salt tolerant tree species.
