Have this account, mowed every ten days. Yes, the dreaded tendayer. Pull up today and notice the yard is super green and lush. Ask the lady if any fertilizer was put on the yard and she informs me, "Yes, my son was in town for a week and thought the yard needed some fertilizer." I'm thinking, great another hit and run fertilizer freak!! This lady has made it clear to me over the years that she only wants the yard mowed every 10 days. I inform her that due to her sons stroke of genius, that I will need to mow it every 7 days at least, maybe every 5 days. She tells me to try and do it every week, but I can tell her dumba$$ kid put down a double dose of 10-10-10. Maybe she'll get the hint when it grows 2 inches overnight!!
