Grass removed from flower bed

Asked October 3, 2018, 7:06 PM EDT

I have a landscaper who is proposing to use a weed wacker to cut the grass down to the soil and then apply leafsoil over it as a method to stop grass growing for my flower beds. Is this effective? Thank you for your help.

Whether this method works well depends on what type of grass weed we are talking about, and how much leafgro/leafmold we are talking about.
Perennial grassy and other weeds are likely to be able to return next year through the soil unless it is very thickly applied.
Annual grassy weeds like crabgrass or the newer invasive species Japanese Stiltgrass, which would normally germinate in spring, might be shaded out with several inches of coverage. (Annual weeds will die with the cold weather).
If it is stiltgrass, it pulls very easily and getting any weeds out of there- pulled or dug and bagged for trash, before they produce seeds would be a good idea.
