Duckweed Eradication - Any experiences?
I am sure that anyone out there with a pond knows all about duckweed - bit like a dog, it's not just for Christmas! I usually scoop it off the surface on a regular basis and add it to the compost bin but this is only a stop gap and it never really reduces the amount of weed. I have recently become aware of products (specifically Ecopond) that claim to rid your pond of the weed if used in the Autumn months - has anyone used any of these products and do they work.
Or any other suggestions would be appreciated.
