How to Grow and Care for Horseweed

Horseweed, also known as Canadian Fleabane, Marestail, Coltstail, Butterweed, Canadian Horseweed, Conyza canadensis

Horseweed is a hardy weedy species that is highly adaptable and can thrive in various conditions, making it generally easy to care for. Key care points for horseweed include ensuring it has enough space to grow, as it can spread quickly and become invasive. Furthermore, it’s vital to manage horseweed's growth through regular weeding and potentially limiting seed dispersal to prevent it from overtaking desired vegetation areas.

Horseweed is readily recognizable as a winter annual with a rosette of hairy leaves. As it matures in spring, it vigorously grows into a slender, upright form, reaching heights of 3 to 6 feet (about 0.9 to 1.8 meters). Its tap root system, accompanied by fibrous roots, anchors it firmly, making extraction challenging. Small, inconspicuous flowers adorn the plant, featuring white ray flowers circling a center of yellow disk flowers. These characteristics are crucial for effective identification of horseweed.
