Duck weed
This year our small garden pond is totally blanketed with duck weed.
Is there a remedy likely to be harmless to the inhabitants? Netting it out seems to stimulate further growth! - John Lloyd Black Country, UK |

Netting it out seems to stimulate further growth! An Oase SwimSkim will remove it eventually but they are not cheap and you will need to empty it's container constantly at first. Once it's got rid of most of the floating stuff it will only need cleaning out every few days as it clears up any new weed, floating leaves, etc. Also provides water movement and aeration. -- Regards Bob Hobden just W. of London |

For an environmentally acceptable solution for larger ponds is the Grass Carp Ctenopharyngodon idella which is a herbivore that feeds on plants and algae (ordinary carp Cyprinus carpio will eat other pondlife). |

I was told that there is very little that can be done if the pond is too small for wild fowl which might eat it. The only things suggested were, buy a pump and some kind of water circulation device to keep the surface moving, or wait for a sharp winter frost then the weed will become encased in ice and can be moved away wholesale. As the latter is likely to be months away, I am considering the former. |

If your pond overflows at one point, pumping water into it from other end can work well as the duck weed washes out with the overflow. If you use tap water, be careful the extra chlorene doesn't kill off any fish you have. Matt |

Thanks, I will live in hope. |

Some years it completely covers the IJsselmeer, although not so far this year. Tourists have been known to take short cuts across canals in the semi dark because they mistook the duckweed for lawns. I nearly fell for that myself when I was a youngster. Recently I saw a dog chase a cat across a duck weed covered pond. They both got a bit wet. Steve -- Neural Planner Software Ltd www.NPSL1.com |

One has to be willing to make sacrifices. :o) Give the pond some shade by planting some shrubs/trees. Encourage ducks, moorhens, etc as they eat the stuff. Try a duck weed treatment but there aren't many and this one is expensive: http://www.aquahydrotech.com/catalog...product_type=1 Keep raking it out. Remember that it does some good in removing contaminants from the water (hence it is cultivated in some sewage/waste water treatment plants. Or try one of these -- you might take baby out with the bathwater but at least you don't have tokeep emptying it: http://www.garden4less.co.uk/hozelock-pond-vac.asp |

It IS expensive but might welll be worth it as 2 of our ponds have duckweed and the third doesn't. If we can get rid of it in those 2, it would be a great boon. -- Sacha www.hillhousenursery.com Shrubs & perennials. Tender & exotics. South Devon |
