We think the question should be why on earth would they not! Our customers lawns are treated with the very best fertilisers, weed killers and moss control available anywhere. All Grasshopper groundsmen are full time employees, they are experts at what they do, and they take pride in their work. The price of our regular seasonal treatments is directly comparable to the cost of the inferior DIY alternatives. Why a home owner would prefer to do the work themselves, with lower quality materials and results is certainly a mystery.
