Northern Milfoil (Myriophyllum)

Leaves whorled in groups of 4 to 6.  Each leaf is divided into 5 to 12 leaflets extending from a stout green central rib.  Form tangled mats on the water surface.  Late summer, some varieties will produce serrated leaves and small flowers clustered on a spike that grows above the water surface.  Treat anytime weeds are actively growing.

E=Excellent, G=Good, F=Fair 


Pellets are a systemic option for Water Milfoil weed control. Pellets can be used for spot treatment or treatment of an entire pond. For best results, apply early spring as new growth begins to appear.
