American Burnweed, commonly known as fireweed, is a rapid-growing broadleaf weed that flourishes in cool, damp conditions—such as those we've experienced recently in LaGrange, GA. This resilient plant often outpaces mowing and spraying schedules, germinating above pre-emergent herbicide layers. Its vigorous growth can be particularly challenging for warm-season turfgrasses, struggling to keep pace with burnweed's rapid expansion.
