The cost of these products is what scares me. It also scares me to try to use it as an upsell .... Then listen to the complaints when they see a weed pop up!!
I thought about maybe trying to include it in the services that clients who chose year round monthly payments. I could easily add a little extra to cover cost, spread over the top of plant beds, and hopefully save my mowing crew some time. ( I mean 5 min x 2 guys x 30 growing season cuts could add up).
It was also suggested that in my area an application of snapshot in spring and app of free hand in fall would get me pretty good control. Not sure though. The local extension office has 2 snapshot apps in their yearly bid...maybe figuring the low rate each time?
