This week’s weed of the week and featured EDIS publication is about galinsoga (Galinsoga quadriradiata). Galinsoga is a common weed in agricultural fields, container-grown ornamentals, landscape planting beds, lawns, gardens, and other disturbed areas. In container nurseries, galinsoga can be found in containers, in pot drain holes, growing through weed mats, and in noncrop areas around the nursery. In landscapes, it is frequently found growing in turfgrass or in mulched planting beds but is also commonly found in cracks in sidewalks and between patio pavers. Galinsoga has a strong competitive advantage in high-light environments and prefers warm and sunny locations.

For more information on Galinsoga quadriradiata, including specific recommendations for chemical, physical, and cultural weed controls, please consult: Biology and Management of Galinsoga (Galinsoga quadriradiata) in Ornamental Crop Production.
