    Not green water!

    I havnt had a problem with green water this year (only string algae way back when) probably due to vigorously overgrown bog that I have. I couldnt see a lot of my other plants anymore... the dollarweed (pennywort?) are taking over!

    I do not want this many of them next year as I really do want more flowers. My question is, how winter hardy these pennywort are! I'll try to yank them out as much as possible but they are quite persistent and ran through other plant roots and it's hard to actually take them all out.

    I'll move them to the part where they cant really take over like this :)

    Any tips of getting rid of them?

    When I've had bog plants take over like that, I've realized that it was because I underestimated their "invasive" properties. So now, I either eliminate that plant all together, or try to stay on top of it from the start. It's amazing how quickly they can go from nothing to totally out of control.

    Yes they are invasive. I didnt know how invasive they are until a few months ago! Last year it wasnt this bad. this year it was just boom and took over. I dont mind invasive bush like mint and lizardtail, but this pennywort is hard to take out!

    Are you wanting to totally eliminate it or just control it? Is it hard to pull up or have quirky roots? Wonder if putting a cut-off flower pot over it would contain it (like, cut the bottom off a pot and use it like a cage)? Guessing that would depend on length of the roots......but you'd still have to catch it before it over ran the sides of the pot. Hmmm, I might have to try that with some aquatic forget me nots. I love the little plant, but it crawls in among other stems which makes it harder to pull out for thinning.

    I found this.....no idea how helpful these treatments are.

    GETTING RID OF DOLLAR WEED NATURALLY.....
    Since this weed thrives in overly moist areas, the best way to treat dollar weed is by reducing moisture in the affected area with proper mowing and irrigation. You should also improve any drainage issues that may be present. In addition, dollar weed can be easily pulled up by hand, though this can be tedious and in larger areas, it may not be feasible. Organic control involves methods that may work for some while not others, but it’s always worth a try to see if one will work for you before resorting to chemicals. These methods include the following:
    Boiling water – Pouring boiling water on areas with dollar weed will quickly kill the plants. However, care should be taken not to get any on other nearby plants or grass, as boiling water will kill anything it comes into contact with.
    Baking soda – Some people have had luck with using baking soda for killing dollar weeds. Simply wet down the dollar weed foliage and sprinkle baking soda over it, leaving it overnight. This is supposed to kill the weeds but be safe for the grass. Sugar – Others have found success with dissolving white sugar over the weed. Spread the sugar over the area and water it in thoroughly.
    Vinegar – Spot treating dollar weed with white vinegar has also been deemed effective as a dollar weed herbicide.

    I dont know if i can kill them with stuff other than pulling them out as they are entwine with other plants. It's send shoots through other clump of grasses/rushes everwhere. It's pertty easy to pull since the roots stay shallow enough but it breaks off easily and every break creates new plant ;)
    I think i'll have to get rid of it. I know how good it is as herb (help with memory, brain, and all that.. it's a very good herb) but I'll have to keep it contain so my other plants in my bog gets a chance of life ;)

    I think i'll try to yank them as much as i can then wait and tank them again then may be spot kill?

    Pennywort is super invasive here. I can't completely get rid of it and when I do pull it, I have to be super gentle and dig for the thread. Some places they don't grow so crazy, like at Addy's I don't think she has a huge problem with it.
    I just yank it by the handful and then let it grow back in.

    Hi Nepen. If they are in your bog get your fingers in the gravel and find the common thread and gently tug at it. That is the only way you can eradicate it all. At least that's the only way I know how to do it. It has been a little bit. :)

    I had some penny wart, yanked out a bit to send to someone that wanted it and the rest disappeared. No problem with it in my yard.

    I yanked them before and they took a clump of sweet flag up with them since their roots went though other plants roots balls, it's hard to actually target only them.

    @Nepen I'm glad you brought this up. Maybe we could get @addy1 to contribute to or start a thread "topic" titled INVASIVES or PLANT AT YOUR OWN RISK. It could list the various plants that are known to be invasive, ranked from [maybe] "easy to control," through "don't go there!" And list certain considerations for each one.

    Sounds like a good idea. I can start a list and we can add to it from there (I know very little plants though)

    Aquatic forget me nots are not as bad as your dollar weed, but you do have to keep an eye on it and thin regularly. It tends to entwine among other plants, though, like the dollar weed, which makes it difficult to pull. I can't recall what the others were, but I've had some that took over, yet were easy to pull out and control [I call that a controlled invasive, LOL], and some that you needed a jackhammer to break out! I think that's the kind of info that would help us as garden ponders! Most plant info won't tell you because you might not buy the plant [but I have seen some sites that give warnings].

    I think it depends on the area that you live what is considered invasive.
