Propagation
Each frond buds off new fronds continuously, so it doubles its surface coverage rapidly without any intervention.
Frequently asked questions
Is Giant Duckweed easier to control than regular duckweed?
Somewhat. Its larger fronds and multiple roots make it easier to scoop out by hand or net than the tiny single-rooted common duckweed, but it still grows explosively and a few leftover fronds will repopulate the surface.
Will Giant Duckweed block light from my other plants?
It can. A thick surface mat shades plants below and may starve light-hungry species, so skim off a portion regularly to keep coverage partial. Many keepers run it deliberately in low-light or betta tanks where the shade is welcome.
