Default Watercress

Mary Fisher writes


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.


That reduces the light level in the pond and thus reduces algal growth,
but the fact that you are removing 4 handfuls a day is also removing the
nitrogen involved in growing those four handfuls, thus adding to the
beneficial effects.

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?
