A natural product to prevent the growth and spread duckweed.
Eco pond Duckweed Control contains a special bacterial culture which removes nutrients which aids growth of common species of duckweed. Once the majority of the existing weed has been manually removed the treatment can be carried out. Duckweed Control is harmless to fish, wildlife or other plant life in the pond.
Duckweed Control is best applied in Spring, however, it can be successfully applied right through the summer and early autumn (whilst temperature remains at a minimum 8-10 degrees) and this will prevent spore formation which otherwise leads to further duckweed growth the following Spring.
