RE: Best red briar killer
Wooddust,
Sericea is definitely invasive as we are having some real problems with it here in KY taking over some of our native warm season grass stands. It is easy to kill back with chemical, but it is such a powerful seed producer and has such an established seed base, that it always seems to come back. We have been working on burning/mowing/spraying regime in hopes of finding a way to rid some stands or Sericea permanently, but it is yet to be seen whether or not that will happen, or whether we are just going to have to deal with it every so often until the end of time!
