This broadleaf weed has a fibrous root system with a shallow taproot. Blooming from May through July, Carolina Geranium produces small clusters of pale-pink flowers with five petals. Reproduction occurs by seeds.

Control

Geranium carolinianum can be removed by hand but only prior to seed formation. Once seeds have formed, hand-pulling can spread the seeds to additional areas of your lawn. If you are unsure if seeds have formed, do not attempt to remove—consult a professional about broadleaf weed killer applications.
