Question From: Albuquerque, New Mexico, United States
Q: Not a lawn problem, but a yard problem. Have a zeroscape yard - no grass, just plants and rocks. We have a white powdery substance coming up around the house foundation, retaining walls and the rocks and lights in the yard. I can rub it back into the rocks but it quickly returns. Seems to be eating away at the stucco also.
A: Judy, I am not familiar with adobe materials but I think it's the cause of the powder. I think it's leaching out of the walls and foundation. Check with construction experts in your area. Best Nancy and thanks for visiting Yardener.com.
