Chamber Bitter; Gripe Weed - Phyllanthus Urinaria
My property is infested with this weed, brought in, alas, with various natives I planted throughout 21 acres. This year I decided to get rid of it, and it has been the battle of my life. I spray it with glyphosate and hand pull some of it, which is back-breaking. My question is in two parts: at what point are the prolific seeds mature? It is much easier to spray it, but I'm hand-pulling it if the seeds look mature, for fear they'll sprout even where the sprayed plant dies. The second related question is: if the seeds are immature, or mature for that matter, does spraying glyphosate interfere with their ability to sprout, such that it would be OK to spray a plant with even mature seeds and let it just fall where it dies, without fear of the seeds sprouting? Or are the seeds impervious to the hormonal disruption inflicted by spraying?
