Pre-Emergents for Oak Seedlings in Groundcover: Try Trifluralin or Benefin+Oryzalin

No pre-emergent labeled for oak seedlings. Dr. Mark Czarnota suggests trying trifluralin (Preen) or benefin+oryzalin (Amaze)—they control broadleaf weeds and might suppress acorn sprouts. Test and report results.

Worth a try; hand-pulling is current norm.
