Heard of grass keeping the lakes clean? An experiment being conducted by the State Horticulture Department.

Vetiveria zizanioides, popularly known as khus grass, will be grown around the lake, which will help the authorities to keep the lake clean. The roots of khus grass have a special characteristic of absorbing the toxins in water and purify it naturally.

Khus grass is being grown in Lalbagh to reduce the expenditure being incurred on cleaning the lake. Visitors have been polluting it by throwing waste into it. The grass will be grown on ramps made of bamboo poles, which will float on the lake. The purpose is to keep the lake water clean and use it for irrigating the garden. The cost of the project will be reasonable as the khus grass is being grown in Lalbagh itself.

The department is also working on beautifying the lake by planting ornamental plants around it. Besides, the department had a plan to create a water fall to enhance the beauty of the lake. It is important to control pollution around the lake and maintain its ecological balance, as the island within provided habitat to various species of birds.
