Okay, here's what happened. About a month or two back I snipped off a piece of one of my peppermint plants (with adequate roots and such) and planted it outside next to a small building of mine. Yesterday I went outside to check on it and it still looked okay, but got told that it was sprayed with Round Up weedkiller only about 2 hours earlier. I don't know if what I did was helpful or not, but I cut off pretty much all of the peppermint that was above the ground (it was only about 2 inches high at most) so only a small tip of the remaining stem was peeking up from the ground, gently removed it from the ground (not taking any of the round up sprayed soil with me), and replanted what was left of it back inside my house with fresh soil and Miracle gro potting mix. Though I know that round up only works if you spray it on a weed and it rains, it didn't rain at all yesterday. Do you think what's left of my peppermint plant will survive? If so, would what grows up new be harmful if someone wants to nibble on some of the leaves or make a tea from it?
Today's Roundup requires only about an hour without rain to be mostly absorbed into the exposed vegitation. How fast and far it travels within the plant is beyond my knowlege, but it works by translocating to the roots, so my guess would be that if your plant survives, that would mean that not much had reached the roots. As for the safety and edibility of the grown plant, I believe Roundup is the same stuff that many years ago Dr. Gordon Shrum ostensibly drank a glass of when he was CEO of BC Hydro to "prove" that it was safe to use as a berbicide on power line rights of way! (Kids, don't try this at home!). Personally - I'd start a new plant. Ralph
O_o ...whoa... ^_^ Thank you kindly for the help Ralph. I'm just curious. Did the Dr. Gordon Shrum guy survive?
I'd start over with a new, clean plant in an area that is not receiving herbicide treatments, such as a container - a good place for notoriously invasive mint plants anyway. Why bother with a situation that has stressful aspects? At this time of the year you can even find small mint plants for a few dollars each (or less) at supermarkets.
