Alot of algae and moss problems are caused due unhealthy turf conditions. Knowing the soild conditions for your lawn is crucial to planning the most effective treatment. The first step is to have a soil test done through your local county extension office or with a home test kit . These results will tell you how much fertilizer is neccessary to bring your lawn to healthy levels and to determine proper lime and fertilizer needs. For most turfgrasses, the pH should be 6.0 to 6.5. Cultural Control Methods suchs as improving drainage, aerating, removing any areas of soil infected with algae and replacing with new soil, and avoiding over irrigating or water buildup need to be addressed in order for fungicides or algaecides to be successful. Southern Ag Liquid Copper Fungcide and Bonide MossMax are two products labeled for treating algae in residential lawns. We would recommend contacting your Cooperative Extension office in your county for assistance in identifying the disease/algae in your lawn. They are the best resource since they are local to your region. After speaking with them and having the disease identified, we will be happy to help with a correct recommendation.
