Seiran from Rancho Cucamonga, Ca writes,

Does the Hi Yield crab grass control also effect St. Augustine grass and prevent its growth?


Hi-Yield Crabgrass Weed Control is safe on established St. Augustine Grass. Hi-Yield Crabgrass Weed Control is a pre emergent and must be applied before crabgrass germinates.
