Our landscape vendor performs two applications of herbicide during a season. The first is typically in July with the second application occurring in the fall.
Once the product is dry, this poses no risk to humans or pets. It dries very quickly, especially in warm temperatures. Herbicide typically will not be oversprayed onto your property. For those who are very sensitive to odors, the smell should dissipate quickly.
The District’s landscape service contract does not include hand-pulling of weeds in open space areas (only in planted landscape beds). Once weeds have been chemically treated, it’s often beneficial to leave the root system in place to help mitigate soil erosion, the weeds will usually lie down once dead, or they can be clipped just above soil level.
