    My pH is 7.8, my parrot feather is yellow and I have one group of
    water hyacinth in the pond and they don't look great either. I
    haven't tried the potash this year, but it is only good for replacing
    potash, and it is my understanding has nothing to do with pH. OK,
    I'll try the potash too. As soon as I send this and tear myself away
    from the chair.

    What is your pH and what kind of filter plants (Not potted.) do you
    have that are green and growing? I'm not against trying another plant
    as a filter plant, I've just had good luck with water hyacinths most
    years, but some years they don't grow in my pond.

  2. Hi Hal,

    As mentioned my pH is over 8. I grow water hyacinth and parrots feather both
    of which thrive in my pond. The only problem I have is my hyacinth doesn't
    too thrilled about blooming. Nitrogen is typically what "greens" things up.
    Try taking them out of the pond and place them in a container with
    fertilizer to see if that helps.

    I'll be interested in answers. Currently I'm at 7.8 in both the koi ponds &
    a little stock tank. The koi pond ones in full sun, aren't doing well, yet
    the stock tank ones w/morning only sun, are a bit better. The Lily Pond, at
    8.2, are really sad. :-( But I haven't been able to grow WH for years.
    Used to be it would grow out of the prefilter and totally hide it. ~ jan

    Try the potash. You have nothing to lose. With a high PH your Iron may be
    tied up. The plants will look chlorotic or pale. I was told this on
    another Forum years ago. I use Ironite in the pots of potted plants now and
    that seems to have cure the problem. It leeches from the pots. I got the
    bag of Ironite at Home Depot. I use 2 Tbs per potted plant mixed with the
    fine gravel or soil.
    The only floaters I have are water lettuce and a few water hyacinths. The
    parrots feather is rooted in the other plants pots. There are no more than
    a couple of duckweed floating in the ponds where the fish can't reach them.

    I'm not against trying another plant
    Usually duckweed grows like wild in the fishless tubs. This year it started
    out great and now is barely hanging on. I tried several garden fertilizers
    along with waste pond water but they didn't respond.

    I don't understand what is happening with WH either. Some years ago
    when I started ponding a friend, George, told me he had tried, but
    couldn't grow them. He had a pond filter that was big, in stages, a
    sweeper pump that kept the bottom swept to the filter and his water
    never greened. It stayed gin clear. He also had a large fish load.
    I believe it was 10 full grown males in about 800 gallons plus filter.
    That was the first time I thought perhaps there wasn't enough nitrogen
    in a pond to support water hyacinths. The though has occurred to me
    concerning my pond, but what does the algae live on?? Irritating
    ain't it??

    Thanks Joe, I'm glad to hear they grow well for you in a higher pH
    than I have. Now I'm still looking for the reason they don't grow
    well in my pond. I have a good fish load, my filter is barely
    keeping up and I don't know......

    They grow wild with plenty of fertilizer, but that doesn't do the pond
    nutrient level any good. I've played musical containers, switching
    them to fertilizer then back to the pond, that just tells me they grow
    well in fertilized water and not in my pond. I'd pull my hair in
    frustration, but I don't have enough left to lose any.

    I have some in a half barrel that have grown into a large bouquet and
    today they are blooming sporadically, you know a couple here and
    there, but they make such a sight this is my second year doing this.

    I've tried potash, magnesium and iron. I never found the chelated
    iron, but I'm guilty of using Ironite. Some years floaters don't do
    well in my pond, period.
    Must be great!

    If they're in the pond with fish, who love to eat their roots, that could
    be a cause. Doesn't solve mine, as none are in with fish.

    I can't even get them healthy with miracle grow. :-( (Is that what you
    At least you've got them growing somewhere. :) ~ jan

    When mine grow in the pond they aren't with larger fish. Some fry did
    get into the plant pond in past years, but they had no real effect on
    the plants. I've even seen them green with very short roots beneath
    the leaves. I have no explanation as to why they grow well some years
    and not others.
    I buy bargain brand fertilizers usually a 1-2-1, like 15-30-15 for
    flowering plants and take whatever brand or type might be available at
    the time I'm at the store and purchasing.
    I don't know why you can't get them to grow with Miracle grow. The
    water hyacinth is such a pig it will eat anything. One thing you
    might try is put some garden dirt in the bottom of a large pot/bucket
    and float them above the dirt. They are pigs in a plant world and
    will find the mud.
