Removing Concrete Dust from Plants

Emergency Situation

Concrete saw dust covers liriope, hosta, azaleas, impatiens, and iris after a driveway replacement. Concern about leaf burn and soil pH changes.

Immediate Action

Wash the dust off leaves as soon as possible to prevent burn. The dust is unlikely to alter soil pH significantly unless applied in a layer an inch or more thick—typical lime applications require much more material to affect acidity.
