The most renowned tea-producing areas in India are located near the foothills of the Himalayan Mountains. The locations above encompass Assam and West Bengal. These areas are characterized by tropical to subtropical climates, with annual precipitation ranging from 1150 to 2800 mm and temperatures ranging from 10 to 35 °C. Furthermore, these conditions facilitate the proliferation of a diverse range of weed species. Weeds interfere with the growth of tea plants at almost all stages, but most interfere during the initial period of plantation. Weeds are the most common pest, reducing tea productivity by 10-50% depending on growth intensity, level of competition, weed type, and the competing ability of clones. Utmost care is required, as if left unattended, the weeds can outgrow the tea plantlets, eventually leading to their death due to tough competition for nutrients and moisture. This review focuses on the weeds in tea plantations in Assam and West Bengal. The study also reveals their harmful and beneficial effects, their invasiveness, and their management.
