Question
I heard the other day there is a new way to poison weesatch.They said it is a little pill you put at the base of the bush, moisture dissolves it, and kills the plant. Have you heard of this? If so, were can a person get it?

Answer
There are several herbicides that will work based on studies done in Texas. A ground applied herbicide will work BUT will kill other vegetation and will last quite some time in the ground. I would stay away form this and only use as a last result. Here is a web link to the information from Texas on spraying the foliage and also on a stem applied herbicide. The method will depend on your plant and the size.
