POISON HEMLOCK AWARENESS NOTICE

Please be aware the Borough has confirmed that poison hemlock has been spotted in tree lawns which have recently been disturbed by construction.  This invasive plant has become a national issue over the past several years and has affected most land developments projects throughout the region because hemlock is a pioneer species, and it can quickly move any time that soil is disturbed.  The Borough is addressing the issue in areas which have been recently disturbed through the separation and streetscape projects.   

Poison hemlock is simple to control and eradicate with hand pulling and the use of herbicide treatments. If found, the Borough advises to remove the weeds, while wearing rubber gloves and protective clothing, by pulling, and following up with an herbicide to prevent future growth. Once the plant and its roots are extracted from the ground, place the plant into a plastic garbage bag and dispose of it into a trash receptacle.

Poison hemlock is a biennial plant that can grow as tall as four to nine feet. The hollow stem is smooth and hairless and has very distinctive purple blotches all over it. It also has large, glossy green, finely divided, fern-like leaves that are smooth and hairless. Its flower is similar in appearance to Queen Anne’s lace and wild carrot.  Poison hemlock can be fatal if ingested by humans or pets.
