How many seasons does it take for a biannual weed to complete its life cycle?

A biannual weed, often referred to as a biennial weed, completes its life cycle over two growing seasons. Initially, during the first season, these weeds typically germinate and grow, forming a vegetative structure without producing flowers or seeds. This phase commonly involves the development of a strong root system and foliage.

In the second season, the biennial weed enters its reproductive phase. During this time, it flowers, produces seeds, and ultimately dies after completing its life cycle. This characteristic distinguishes biennial weeds from annual weeds, which complete their life cycle in one growing season, and perennial weeds, which live for multiple years.
