picked up a new lawn the last week of may.customer went with a cheaper service first and it was only cut three times since the start of the season. i took it over grass was REAL tall now its on a regular schedule every 5-7 days and the front is browning out and the customer is conivinced its my fault im cutting to short or something. i cut it at 4" the first time 3" next 2 times and 3.5" the last time. all other lawns are still green and only the front lawn at this house is browning.we havent had much rain since i started cutting it she refuses to water because she never had to before mid july before. could it still be stressed out from the first cutting when i had to take off so much?
