OH2 Ornamental Herbicide – 50 Lbs.

OH2 Ornamental Herbicide is a pre-emergent herbicide in a granular formulation which is very effective against hard to control broadleaf weeds and grasses including chickweed, spurge, oxalis, crabgrass, annual bluegrass, fireweed, and more.

It features two active ingredients, Oxyfluorfen and Pendimethalin, a great combination that will help prevent and control weeds in container, field grown and landscape ornamentals.

It is recommended to repeat application with approximately 3-month interval during the growing season if you’re aiming for season-long control.
