How to Use & When to Apply:
Use Ortho Grass Killer when grasses or grassy weeds are actively growing during the season. The herbicide is absorbed through the leaves and moves down into the roots, which kills the plants. This product is safe to use in and around broadleaf shrubs and plants such as (but not limited to) azalea, boxwood, holly, dogwood, and spruce.
Spray this product until the leaves are covered but not to the point of dripping. You may need to reapply a few weeks later if regrowth appears.
Ortho Grass Killer kills grass and grassy type weeds such as barnyardgrass, crabgrass, brome, foxtails, goosegrass, and panicum. Also kills perennials like bermudagrass, johnsongrass, and quackgrass, though these grasses are very tough and reapplication may be required.
Pros to Using Ortho Grass Killer
- Good for spot spraying when you don’t need a lot of chemical
- Will not hurt broadleaf perennials and shrubs–kills grass growing within them
- For lawns and gardens
- Easy to use sprayer
Cons to Using Ortho Grass Killer
- More expensive than non-selective herbicides such as Roundup
- May need repeated application if regrowth occurs on grassy weeds
