Q.How to kill a weed that has overtaken my dad’s garden.
Years ago my dad’s friend suggested that he put some of his sheep manure on his garden. Ever since then there is a weed that has overtaken his garden. I even tilled my garden and it started growing here. Is there a treatment we could do in the spring to kill it? The first picture is it at full bloom. The second picture is of it taking over this row.

Use a pre-emergent in spring to eradicate quickweed. If any remain dig by hand or use a post-emergent herbicide.
