Ugly looking plant--looks like the plants on the Sci-fi,horror movie "Day of the Triffids!"Only way I would want to takle those is on a tractor with a brush hog!Or try salt water on as done on that horror movie-that killed and dissolved the plants.
between all of my butterfly garden plants and rose bushes, so ground clear or weed whacking is not an option. Preen does not work, so I get my garden gloves, dandilion weed puller, and get them before they bloom or seed.
Doing my part for the bee's, butterflies, and that is "Salt of the Earth!
I tolerate quite a lot for them. Is one's way the only way?
