False Loosestrife (Ludwigia palustris) is a perennial commonly found throughout the Upper Midwest along the muddy shores of freshwater streams, rivers and ponds. It has lance-shaped leaves ½ to 2-½” long, both floating and submersed. Leaves can be alternate or oppositely attached with smooth toothless edges that taper at the tip. Roots form in the stem joints. It has a small inconspicuous 4-sided flower in the leaf axils that bloom in August through September.
False Loosestrife reproduces from seed.
2) Aquacide Pellets are a good systemic control option, especially when applied early, prior to seed. Best applied early spring as new growth begins to appear. Aquacide Pellets can be used for spot treatment or treatment of the entire pond.
