Q: SOS!!! My husband had concrete driveway pad replaced; dust from concrete saw (used to break up old pad) covers my liriope, hosta, azaleas, impatiens, some iris. what is best way to remove it? I’m concerned it will change PH of soil as well as burn leaves.

A: The dust might burn the leaves of nearby plants so wash it off as soon as you can. I doubt it will change the pH of the soil. It takes a good bit of lime to raise acidity…unless there was a layer an inch or more thick I don’t see it being a problem.
