Hi Jim..

Thanks for the kind welcome..! :-)

As I commented on TFA,
mine has beeter luck where it is neither crowded out nor
eaten up.

Yeah. At the moment we've no duckweed eaters in the barrels
and summer ponds, too..

@ Jan:

Would recommend to remove it (duckweed) from the surface
because of the gas exchange..

@ all:

Thanks..!
