Pre-emergents (other than Treflan)
I am on the Landscape Committee for our Townhouse Association. The Nursery with which we are working has a good plan for the restoration of the grounds, except that we are concerned about the pre-emergent (Treflan) suggested for a strip/berm along the sidewalk and public street on the west edge of the property.
Can you suggest an effective non-toxic (non-carcinogenic to humans) pre-emergent that is currently available? We are older mostly-retired residents and want to avoid any Round-up type pesticides after some of us have had serious health problems after use of Bayer-Monsanto products. (Run-off can go into street drains.) Can you help?
