this a weird time of the season for this question, but i figured many of you veterans would have experience with a problem i experienced this spring. i had a customer quit on me after one application because i put down a premergent and he couldn't reseed some spots in his lawn like he planned. how do you guys avoid this? when you send you renewal notice in january or february do you write that you will be applying a crabgrass preventer and they won't be able to reseed? Do you just apply and then tell them, and if they get pissed they get pissed? Etc...?
