Not the common, annual milkweeds that the Monarch butterfly catterpillars eat but the recent (in my area) perennial type that ryzhomes.
I started noticing these things 10-15 years ago but thought that they could be easily controlled with broad leaf herbicides so did little.
Damn things are perennial, ryzhome, and are unaffected by just about any broad leaf herbicide that I am aware of. Yes, Round Up will kill them but I have them in areas where I cannot kill the grass.
Once established, they can grow densly and rapidly enough to choke out even heavy grass. One must mow every 3 or 4 weeks to prevent this.
Local farm store had Crossbow on sale so I bought a gallon to experiment. Material says "suppress" at highest recommended concentration.
Going to experiment this fall.
Anyone have first hand experiance?
