Q&A – I have black mold on my flagstone deck. How do I get rid of it?

Question:
I have black mold on my flagstone deck. How do I get rid of it?
​​
Answer:

Mold grows best in shady moist environments. Eliminating those conditions may reduce the mold growth. University of Memphis Director of Landscape Joellen Dimond says there are products available containing alkyldimethylbenzylammonium chloride that control mold. Follow the label directions, but they will probably only need to be applied once a year. Joellen discourages using bleach or vinegar because of the problems those chemicals can cause to surrounding plants.
