Lawn Weeds
I have been lurking here for a few weeks and would now like to tap your
not inconsiderable collective knowlege. I have two problem weeds, one in each of my two lawns. Both have been treated with Verdone and a spray on spot weeder with no effect. The first is https://www.dropbox.com/s/41828lh67k..._1921.JPG?dl=0 https://www.dropbox.com/s/zj1bm8c9rr..._1922.JPG?dl=0 This one has purple flowers looking somewhat like clover and the second is https://www.dropbox.com/s/tudftpbyxs..._1923.JPG?dl=0 https://www.dropbox.com/s/5qeeo1g96g..._1924.JPG?dl=0 The foliage is purple and seems to shed water - it spreads readily. I appreciate that one answer is to dig it all up and re-seed but the second covers a considerable area and appears to spread from the smallest fragment TIA Malcolm Race |

Try nuclear weapons, or glyphosate and often. Regards, Nick Maclaren. |

I appreciate that one answer is to dig it all up and re-seed but the second covers a considerable area and appears to spread from the smallest fragment The first is Self-heal which is quite tough but a good raking before cutting will lift the stems above the level of the grass so that they will be cut off. This will control it and may eventually kill it. The second is Oxalis and I think that the only way to deal with it is with repeated verdone2 treatments. It produces underground bulbils which can be as small as a mustard seed but will still grow. Killing off all leaves as soon as they appear may be the only solution, but I would be very interested to hear the views of others. Ardmhor |

Try nuclear weapons, or glyphosate and often. Agree the second one is Oxalis and a nuclear bomb would just spread the seed over the whole country! I have it here, it seeds into the front garden where I constantly try to control it, it seeds into pots where I try to pull it out, it seeds into paving where I use a flame wand to control it, I try not to let it seed but it hides under other plants. Luckily it does not appear to like our grass. If you get it in a packed greenhouse OMG total repotting job. BTW don't try composting it, dump it. -- Regards. Bob Hobden.

My worst fears are confirmed - dig it out seems to be the best option in both cases :-) Malcolm |

Dig it up, religiously. That's not too hard, as its flowers stand out well. It's very attractive, and a functional lawn plant, but is much darker than grass. I let small amounts of it grow in my lawns. It isn't too invasive and has nice flowers. But then I don't like a monochrome green lawn. I only really draw the line at dandelions - they have to come out. Verdone will kill it and a good raking and hand weeding will easily thin it out. and the second is https://www.dropbox.com/s/tudftpbyxs..._1923.JPG?dl=0 https://www.dropbox.com/s/5qeeo1g96g..._1924.JPG?dl=0 The foliage is purple and seems to shed water - it spreads readily.

Try nuclear weapons, or glyphosate and often. It is very common around here but it doesn't cause any bother at all in my lawns. Paths and everywhere else but not in the lawn. I'd have expected Verdone to kill that too but you might have to use a bit more. Try a weed & feed treatment in spring. Grass should be able to out compete the oxalis in a healthy lawn. -- Regards, Martin Brown |
