To get rid of nostoc algae, a combination of physical, chemical, and environmental methods is recommended. Physically remove the visible growth using a rake or shovel. Chemical herbicides specifically targeting cyanobacteria or algae can be used to kill the remaining nostoc. Alternatively, natural methods like applying vinegar or hydrogen peroxide can be effective in eliminating nostoc. It’s also important to address the environmental conditions that promote nostoc growth, such as excess moisture and poor drainage. Reducing water accumulation and improving drainage can prevent future infestations.
