Know before you buy
No, Ornamec 170 is specifically formulated for 'over-the-top' application. It is safe to use on over 400 labeled species of ornamentals, shrubs, and flowers without causing plant injury.
You can expect grass growth to stop within 48 hours of application. Complete death of the targeted grass typically occurs within one to three weeks.
Ornamec 170 is effective against a wide range of grasses, including Bermudagrass, Crabgrass, Barnyardgrass, Foxtail, Goosegrass, and Quackgrass.
Ornamec 170 is designed for use around ornamentals, trees, and groundcovers, not as a general lawn weed killer. It is specifically labeled for use in areas like junipers, hydrangeas, and crepe myrtle, rather than for broad-spectrum lawn maintenance.
It is safe for many listed tree species, but you should always check the product label to ensure your specific variety is included. It is widely compatible with common landscape trees, but verifying the label is the best way to ensure plant safety.
