What is duckweed?
Duckweed or Lemna Minor is amongst the smallest of the flowering plants found worldwide. It is a perennial aquatic plant with 1-3 fronds or tiny leaves. Root hairs appear with every leave and hang below the water surface deriving nutrition from it while the leaves float above water covering the surface as a thick mat. This characteristic of the weed often make pond keepers mistake the duckweed infestation for algae bloom.Unlike other aquatic plants which may float above but are rooted at the bottom, duckweed in ponds, lakes derives nutrition from the water. Water bodies with excessive nutrients offer a favourable environment to multiply prolifically. These plants, under ideal conditions could double the covered surface area in less than 2 days. Since it is a plant, it does not respond to algae treatments. One should make special efforts to identify the type of infestation prior to any treatments.
