Duck Weed

[Uncleman]

Thanks for helping me with this. I never even considered that it might not be duck weed - I really know nothing about water pond biology, but I do love them . I would like to know how to control this , short of any chemicals, and I'm grateful for your help.

No worries on introducing any fish that don't belong, I'd never let that happen.

Thanks

I always thought duckweed was the little floating leaves.

There are several kinds of duckweed, small leaves, larger leaves, ivy-leaved, but the one Peter pictured (Lemna minor) is by far the most common.

Just bought 5 cups full on Monday.... and poured them in the pond yesterday when they arrived... already half eaten... damn water breathing pigs. The duckweed had no hope.

Appears to be pennywort.

Or from the pic "quarter wort"
