A weed may be described as any plant or vegetation that interrupts farming or forestry objectives, such as growing crops, grazing animals, or cultivating forest plantations.
A weed may even be defined as any plant growing where it is not wanted. For instance, a plant may be valuable or useful in a garden, farm, or plantation. But if the same plant increases where it lowers the value of agricultural produce or spoils aesthetic or environmental importance, it is considered a weed. Yet, some plants are still weeds regardless of where they grow.
