In this month’s column of In the Grow,\u00a0B. Rosie Lerner, Purdue Extension Consumer Horticulturist, addresses algae that can pop up on stone, concrete, gravel or even lawns this summer as we are getting large amounts of hot, rainy weather.<\/p>\n

This terrestrial algae known as Nostoc can look unappealing and also be a slippery\u00a0safety hazard, but unfortunately, there isn’t much to do about it. Raking the algae will just spread it to larger areas. Keeping the area aerated and dry as much as you are able can\u00a0help a little with controlling\u00a0this algae, and applying copper sulfate will also shrink it a little bit,\u00a0but it will just reappear when warm, rainy weather conditions occur again.<\/p>\n
