Growth of moss is usually a result of inadequate drainage, shade, low nutrient level and/or acidic soil. Moss needs moisture to grow but can survive periods of drought. As moss thrives in damp conditions, it develops in areas that get the least sun, have poor drainage and where the soil is compacted. We can spray and treat moss where ever it is found. i.e. Any damp and shady area of your property such as roofs, paths, fences, lawns and driveways.
