How long can quick weed seed survive in the soil? What is the best way to eradicate it?
Becker County Minnesota
I really can't say how long the seed remains viable. The best way to get rid of it is to pull it as soon as you can or apply a herbicide. Apparently it has the ability to produce more seeds almost immediately after it has bloomed. Sounds like it could quickly become a problem. Here is some more info about it. https://www.bbg.org/news/weed_of_the_month_galinsoga . https://www.minnesotawildflowers.info/flower/small-flowered-galinsoga
