What is the life cycle duration of an annual weed?

The life cycle duration of an annual weed is typically one year. Annual weeds germinate, grow, flower, and produce seeds all within a single growing season. After they complete their life cycle, they die, and their seeds can remain viable in the soil for several years, potentially sprouting in subsequent seasons. By contrast, biennial and perennial weeds have longer life cycles; biennials typically take two years to complete their cycle, while perennials can live for multiple years. Understanding the duration of life cycles for different types of weeds is essential for effective weed management, particularly in determining appropriate timing for control measures.
