Can anyone help me eradicate russian thistle? Up to 3' tall, DEEP running roots, sm prpl flower & LOTS of seed
Answers:
Cut off the flowers so it cannot produce seed (if this is feasible, it will help!). If you can, wait until after a heavy rain, then go out and start pulling. The rain will hopefully loosen up the soil which will make getting the entire root out of the ground much easier. You have to get the root though, otherwise it will just grow back.
If you were really desperate, get some roundup and go with the highest recommended rate on the label (the label is the law). Wait about two weeks, then reapply the round up. A one shot application will not suffice. (Hope there aren't any plants nearby that you would want to keep.)
Good luck

We have Russian thistle on the farm all the time. Get a Roundup type product and put a little 2-4-D in it and spray when their is no wind to reduce drift.
