Groundsel – also referred to as Common Groundsel, Grimsel, Simson, Birdseed, and Ragwort – can be either a winter or summer annual broadleaf weed. Preferring highly areas with little competition, Senecio vulgaris is often found growing in low maintenance lawns, gardens, nursery plots, and along railroads and roadsides. Groundsel can be found throughout much of North America.
Identifying Groundsel -
Groundsel can be a winter or summer annual. It can be identified by its branched stems that are smooth, frequently rooting at the lower nodes. The leaves are fleshy, sparsely hairy to smooth, and the lower leaf blades taper to the petiole.
Blooming from June through October, Groundsel produces small clusters of flowerheads that are composed of several yellow disk flowers. Reproduction is by seed.
*NOTE: Groundsel contains alkaloids that can cause liver damage in horse and cattle.
Groundsel Control -
Groundsel can be a problematic weed if conditions allow it to produce seed in your lawn – especially common in cooler, wetter months. While cultural weed control methods and good turf management practices can help prevent this pest from going to seed, once it is present in your lawn, professionally selected and applied herbicides are typically necessary for removal.
Scotts LawnService uses a selective systemic weed control program to fight Groundsel in your lawn, which ensures the herbicide is moved throughout the weed, killing it completely root and all.
