Unfortunately, two months after moving in, the once pristine pond was covered in watermeal, a tiny plant that can quickly coat the surface of a pond with a soft, green vegetation.

Duckweed and watermeal are amongst some of the weeds that thrive in nutrient-rich bodies of water such as farm ponds, but they can slowly choke the life out of those ponds.

Duckweed and watermeal are just two types of weeds that most pond owners seek to control with chemicals such as diquat.

Duckweed — so called because ducks eat it — is a flowering aquatic plant that floats on or just below the surface of still bodies of water, while watermeal is the world’s smallest flowering plant.
