Geranium carolinianum Herbicide

Description of Geranium, Carolina (Geranium carolinianum):
Carolina geranium is an annual weed that can be found in the lawn in winter. This pest tends to thrive in poor soil conditions with little permeation (rocky, dry, clay soil) and partial shade. It's difficult to control due to the coating on the seed that is impermeable to herbicides. The pink to red stems have spiky hairs with two leaves per node.
