Treatments start at £25 for a small garden and one off treatments are available.
Generally though my regular customers choose to have their lawns treated three times per year, in Spring, Summer and late Autumn in order to keep their grass healthy all year long and weeds/moss kept under control. I only use high quality, longlast micro pellet fertilisers and professional grade pesticides.
I do not use annual contracts preferring to let the quality of my work, and high level service that I provide to retain my customers.
