Effective Yellow Nutsedge Pre-emergents
I have a lawn in Kansas City of bluegrass and perennial sports turf rye mix (Estate Mix is the brand). I did a full kill/reseeding last fall and ended up with a bad case of yellow nutsedge, despite a thick lawn. Many of the post-emergents did harm to my grass. Is there an effective pre-emergent or winter product I can put on my yard to effectively control the yellow nutsedge? My lawn is an "estate mix" of bluegrass and perennial sports turf rye mix. Thank you.
Unfortunately there is not a pre-emergent that is effective for nutsedge. Nutsedge can only be treated with a post emergent such as Sedgehammer. You may contact your local Master Gardener for recommendations that would be best for your county and region.
