I am in coastal Oregon and have a very nasty little weed that I can't get rid of--it's about 6" tall (although I've seen it grow taller when necessary to reach sunlight, right thru other plants--as much as 2' taller!) It has segmented stems and roots that are very reed-like with 'needle' like foliage. I've been told that NOTHING kills it - (including toxic chemicals) short of smothering it with weed barrier which has to be left in place at least 3 years!!! It is fond of poorer soils and full sun.HELP, please I don't want it taking over my yard.
Hi scordra, you would probably be better off posting your question in the Invasive Plants forum http://davesgarden.com/community/forums/f/invasives/all/ This forum is for questions about the Plant Files database, anything to do with care/eradication/etc of plants will probably get more answers in the other forums. If you don't know the name of the weed, it might also help to post a picture of it in the Plant Identification forum first to find out what it is, then people can make better suggestions on how to get rid of it.
