Donna Ah, now that's interesting. The pond with no fish is the worst affected, the pond with a few fish has some duckweed and the pond with loads of fish has none. Thank you, Donna. The only problem is that we want to keep one pond fish free so that other wildllife are safe from their predations. Life is full of decisions! Could you scoop up some of the duckweed from the fish free one and dump it in the lotsa-fish one to give them a treat ? |

No, what we have is duck weed. And it's worst on the pond we don't want to put fish into! How about using a vacuum cleaner made for cleaning swimming pools It would clog up in seconds and take the small but desirable things with it, like frogspawn, newts, dragonfly larvae etc! -- Sacha http://www.hillhousenursery.com South Devon Exotic plants, shrubs & perennials online |

It's taken me years to get rid of the stuff on our pond, had to buy a skimmer (Oase SwimSkim) in the end and that has worked so far. Never seen any of our fish eat it, indeed when they gulp down a mouthful of pellets and accidentally get some Duckweed too they spit it out. Maybe it's not carp that eat it. Thanks, Bob. I'll look that up but probably not to be used until after the tads have hopped it?! We have all sorts in our ponds, some carp, some goldfish, some goodness knows what. All seem happy and are breeding, so something must be right. But the wildlife pond need the skimmer most so I'll look at that once the spawn has hatched. It will need cleaning out at least daily at first, then after it's removed the visible duckweed and other floating stuff you can extend the clean out period. There is always duckweed hiding in places to take over again. As far as I can see, one flake of duckweed rapidly becomes thousands. It's terrible stuff for spreading. We're stumped then, because we could only clear it when we are in France, which is three or four times a year. I see the problem has even made it to today's Grauniad. But they have nothing much to say and no easy solution either: http://www.guardian.co.uk/lifeandsty...d-gardens-lia- leendertze -- Kate B PS 'elvira' is spamtrapped - please reply to 'elviraspam' at cockaigne dot org dot uk if you want to reply personally |

I'd have thought it's possible that it's the fish that are keeping the pondweed from growing on the fishy pool. But then, I've no experience with ponds, fish or duckweed! |

(Your sig-separator's borked - this time - two trailing spaces... Probably, it would work, but duckweed is not too difficult to keep in check just by raking it off the surface. Bleach in your pond paraphernalia will kill a hell of a lot more than duckweed - and it's not certain that it will kill all the duckweed, anyway, unless you really go over the top with it. -- Rusty Growing old is mandatory; growing up is optional.
