What to do about this plant?
We can not identify this plant, but it spreads like crazy taking over our flower bed and now spreading to our lawn. Can you give a link to tell how to control it -- actually to get rid of it. Thanks so much.
We think this looks like Carolina geranium (Geranium carolinianum) also known as wild geranium or crane's-bill.
It is a biennial, and spends it's first year as a low rosette and overwinters in that form. The plant dies out after making seeds. Reproduction is by seeds, which can germinate in late summer/early autumn or even spring. It tends to grow on dry, low fertility sites.
The least toxic method of control is hand weeding.
In your lawn you can use a broadleaved weed control, and in your garden bed you can carefully apply a non-selective weed killer containing glyphosate (like Round Up), being careful not to contact desireable plants. Follow all label instructions for any herbicide/pesticide.
