I had this weed and it is plain out scary. I took it to the Ga Ext. They gave me a name for it other than Walter’s. They told me to do pre-emergent in spring and fall and it would take about 3 years of this to kill it. By the time I got this info it had spread into our lawn that was fescue and it was impossible to contain. The first year it grew chest high because of the flower bed it was in. I would pull it up and the next morning it would be enmass covered again. I never saw anything like it I shared plants with children for their flower beds and it was in soil and got all over their place. It’s unbelievable. I bought up a potted plant recently and recognized that in the soil was starting two of these “from hell plants”. I immediately garbaged the whole thing. I cannot bear for it to ruin another yard (we moved from the previous house and yard. No,not really because of the plant.).

Born pregnant is a good name for it. Otherwise known as mulberry leaf weed, this aggressive annual is encouraged by attempts to fight it. Spraying poison on it or pulling it means exposing the previously dropped seeds to light, and this causes germination. Preventing the seeds from getting light seems like the best way to stop this plant. Mulch heavily after pulling, and throw the pulled seed covered weeds in the trash or burn them. Other people may discuss pre-emergents, and they may help too, but it seems like you would have to keep putting them out, and you wouldn’t be able to plant vegetable seed.
