Eastern Turf Maintenance

Contracted Eastern Turf Maintenance to fertilize and control a ground ivy issue my prior service did notOver the past two years it has gotten worse and now covers almost 1/of my back yard...! Called 3-times over past summer and while they came out...it continued to get worseWhen seading time came...they couldn't do anything as it would possibly kill any new grassI sprayed a couple small areas with a lawn weed killer from Home Depot and it killed the ivy and did no damage to surrounding grass!! What was it I was paying for
