Willow herb

gnoshgnosh Posts: 22
Hi , Willow herb has popped up right out of the centre of water avens in a pond and is growing like mad . Will this be harmful for the fish ? I can’t find a definitive answer so far on Google . The water avens were bought from a reputable company last year . It’s not unattractive by any means but I don’t know if it’s toxic to aquatic life ?

    I have it growing out of most of the baskets in my pond and it's been happening for years. I pull it out frequently but seeds just drift in and more appear. I've never noticed any ill effects - my pond is teeming with newts and other life.
    Willowherb produce masses of tiny fluffy seeds that get blown around everywhere.
    Try and gently pull it out if you can reach it or there will be 000's more seeds floating around soon - the willowhers in my garden are just about to flower - so I'm rushing round pulling them up before they do

    Willowherb often grows as a marginal pond or river plant. It’s not toxic to fish etc and apart from it being ‘a bit of a spreader’ to put it mildly it’s not a problem.
