Torpedo grass (Panicum repens) is the most aggressive weed I have in my garden. In my garden? Heck, once it got started, it is showing up everywhere. The root runners are down about 12 to 18 inches under the surface and unless you dig every piece of it up, it regrows at an even faster rate. I believe it came in in a purchased plant pot, because in 2000 when we moved into our home, the yard had zero torpedo grass. Does ANYONE have any methods of killing this scourge without killing everything it comes up in. It seems to specialize in coming up intertwined in the root system of another plant.

I am totally commiserating with you. Only digging out every inch of it is effective in the long run. Thumbs down

I try to keep in under control but it comes up even through the mulch if I don't put down a heavy barrier first. I have been trying a grass killer that kills the roots too. I have been told that you can kill certain plants without harming surorunding plants by putting weedkiller in a hypodermic syringe and injecting directed into the plant but I haven't tried it. It may work better this way if you use a more concentrated dose since the runners can be pretty long. I may try it this weekend as I have a small amount of it in my center bed.

Yep. I'm constantly after it. It's currently trying to invade my peanut patch. That won't do...
