Could they have gotten sun burned?
Maybe they were raised in a greenhouse.


That is exactly what I was going to say Kathy....my duckweed and azolla does
the exact same thing when first brought outside to the ponds. It will recover,
but I would try and shade it a little for awhile if possible......Jerri



Good point -- I don't know the answer.It's been cloudy for us lately, though, so the
plants weren't getting a whole lot of sun. And I never took my summer shade cloth
awning down over the pond. Maybe just a little was too much? I'll leave some of it
in for a while and see what happens.
