- How to grow duckweed in a pond
- Choose a pond in full sun with slow moving or still water, that already contains fish, preferable koi, goldfish or carp, and other aquatic plants.
- To help the duckweed become established, fill a plastic bucket with water from the pond, making sure you do not have fish or snails in the bucket. Float the duckweed in the bucket. You can partially submerge the bucket in the pond, just make sure fish cannot enter the bucket.
- Add pond water as necessary to keep the bucket at least half full of water. It will take 3 to 7 days for the duckweed to multiply.
- When the duckweed has completely blanketed the water in the bucket, use a fish net or plastic scoop to gently transfer most of the duckweed from the bucket to the pond. Leave a few duckweed plants in the bucket to continue to grow and multiple just in case the duckweed in the pond is eaten by fish.
- Continue growing duckweed in the bucket and transferring into the pond until you have sufficient duckweed growing in the pond.
