Will Tenacity work on Nutsedge growing in my Oporum ground cover?
Tenacity is a systemic preemergent labeled to treat for Yellow Nutsedge only, but not does list other types of nutsedge. We do carry Sedgehammer, a post emergent which is labeled for Purple and Yellow Nutsedge control. We recommend contacting your local Master Gardner for clarification on the effects of either of the products on you oporum ground cover.
