The webinar will be recorded for anyone unable to attend the live session.


Toni DiTommaso will introduce the new edition of his comprehensive reference book, Weeds of the Northeast, and answer your weed related questions.

The new edition covers 500 common and economically important weeds in the region south to North Carolina, north to Maine and southern Canada, and west to Wisconsin. This practical guide includes descriptions and photos of floral and vegetative characteristics, giving home gardeners, landscape managers, pest management specialists, and allergists the ability to identify weeds before they flower.

Bring your curiosity and your all your weedy questions.
