Watercress is a useful way of decreasing the nitrogen level (and hence
blanket weed) in garden ponds - chuck a handful in, wait for it to grow
massivley, then heave most of it out and compost it. Repeat.

Our pond water is very clear despite being full of dead vegetation (we
really must get round to cleaning it out ... ) but the water is clear as
clear, presumably because it's covered in duckweed.

Every day I pull out four large handfuls and line them up for the hens, who
love the weed and the things in it. Of course they all three go to one of
the heaps!

Just wondered - is duckweed edible for humans?
