Definition: Monoculture means the use of land for growing only one type of plant, or the plant culture that results from such use. The practice of monoculture on a landscape thus has an effect that is the opposite of biodiversity, and can sometimes be responsible for the spread of plant diseases. However, the planting of bedding plants en masse is a widely encountered example of intentional monoculture. Sometimes monoculture is unintentional, as when an invasive plant crowds out all competition and dominates an area of the landscape.
Examples: Japanese knotweed is an example of a weed that forms a monoculture.
