I have a small pond (1/2 acre). What does duck weed look like? I have a lot
of a vinous growth plant  (long strings) under water. What can one do to
reduce cattails?

Hmmmm...

So...

Well...

It is like this...

Duckweed (Salvia) is a rather interesting plant.   It tells you a whole lot
about a body of water and in "some" bodies of water it plays a critical
management role.

I guess what I am saying is I hope you have a big pond, and not one that was
covered from shore to opposite shore by salvia, and in such an event that
prudence dictated that you not remove a disproportionate amount of duckweed.

A few things a pond covered in duckweed benefits from.   Cooler water as the
leaves reflect the sunlight, oxygen rich water as the salvia actually
deposits oxygen into the water via the root, and an extra area of
biodiversity via the habitat that the dangling roots provide.

I have unfortunately seen several small ponds destroyed when eager new
owners mistakenly skim off al the duckweed they see in order to tidy up the
pond, what can follow is a dramatic rise in temperature, oxygen depletion, a
sure fish kill and then a massive algae bloom created from the newly
introduced sunlight and the rich water from all the decaying fish.

Just an FYI for those with small ponds.
