Winter weeds are the sneaky ones. They germinate in fall or early winter, grow extremely slowly over winter, then surge with sudden growth as spring weather arrives, seeming to be everywhere, all at once. Winter weeds, including henbit (Lamium amplexicaule), purple deadnettle (Lamium purpureum), chickweed (Stellaria media), and Persian speedwell (Veronica persica) are generally both prolific and pesky.

The solution to preventing winter weeds is a fall application of Preen Garden Weed Preventer. Preen Garden Weed Preventer provides a low-maintenance solution for stopping winter weeds from taking over the ornamental spring garden. Preen works by stopping weed seeds from sprouting. Preen Garden Weed Preventer forms a barrier that keeps weed seeds from germinating in flower beds. Moreover, since cold temperatures actually lengthen the effective time of Preen, an application in fall also prevents weeds from sprouting in very early spring. Preen thus provides a “double jump” on spring weeding tasks by tackling these off-season weed invaders.
