  1. Hmmmm....Up here in Ontario it has been the hottest summer on record. Everything is growing twice as fast than we are used too.

    I keep forgetting about fertilizing lilies. Ours live in 30" tubs
    filled with 2" rock and also on the floor of the cement pond. It
    would be an interesting experiment to fertilize the tub groups and see
    about flowers. Mostly, we have avoided adding anything but potassium
    to the pond, considering the fish to be the nitrogen adders.

    How do your fertilizer stakes affect the general pond algae levels?

    Most commercial fertilizers are N-P-K, N = Nitrogen, P = Phosphate and the
    K is Potash. Phosphate is what makes things bloom (including algae) the
    nice thing about Phosphate in a tab or spike, when inserted into soil
    phosphate binds to clay.

    Considering I have mostly sandy soil it apparently doesn't take much clay
    in the soil for it to bind up that phosphate as my ponds are clear to the

    My biggest problem this year was due to cool weather this spring, I got
    string algae because the higher plants were slow to get going. That's
    cleared up in the koi pond, but in the lily pond, it is now sitting on the
    bottom with anacharis and hornwort growing out of it. A part of me wants to
    rake it out... but the other part wants to leave the anacharis and hornwort

    I'm hoping come August heat the lilies will take off and shade the string
    algae to nothingness.

    So to answer your question, as long as you're inserting tabs or spikes
    before the soil, I see no problem. With rock.... I guess it would depend
    how clean the rock is.

    I know I had to feed the lilies in the holding tubs this week as they were
    looking a bit anemic. 1 tub has 2 wakins... and the other did have taddies,
    but it looks like they all turned to frogs so I need to add more taddies
    from the cooler kiddy pool. ~ jan
