My pond is covered with Duckweed. Has anyone ever used it for mulch? I am trying it around my strawberries. A raccoon digs up mulch including plants when I use composted leaves. So far it hasn't touch the duckweed.

wow someone chatting about duckweed..lemna.. :)
i did research on duckweed in college..
yes..you sure can use it as mulch..compost..feed for animals..
unless you have a HUGE pond.im guessing you wont get alot..but
duckweed takes in alot of N and other minerals from the water..
good luck to you..

I have 25 strawberry plants I put in this Spring and I have muched them with the duckweed. My pond is about 15' in diameter when it is full. Somewhat smaller at 3' below the rim. The entire is , or was covered with duckweed and no matter how much I take out it is back the next day, just a little thinner. I may start using it on the rest of the garden.

From what I have read, water hyacinth makes good fertilizer, too. This is the plant that clogs the canals in Florida.

honeybee..i would think so too.. i dont know from my reading
but i agree..these floating plants absorb nutrients from water..some
good some we dont want in our soils.but..these plants do what they do
in eastern europe..duckweed has been used to absorb heavy metals from
polluted waters..then duckweed disposed of..
im sure there are some university studies of water hyacinth..and its possible
value in composting,animal food,biofuel..

tropicalnut777 - if a commercial use for water hyacinth is ever found, one can be assured that someone will find a way to make money from it. ^_^

The folks in FL would never consider it endangered. It is awful stuff.
