name the five types of weed on the basis of condition required for the growth
Answers
Answer:
So what are weeds and where do weeds grow? By definition, a weed is known as “a plant in the wrong place.” For the most part, these plants are known more for their undesirable qualities rather than for their good ones, should there be any.
Annual types – Annual weeds germinate and spread by seed, having an average lifespan of one year. These include both winter and summer types. Winter annuals, like chickweed, germinate in late summer/early fall, go dormant in winter and actively grow during spring. Summer annuals, such as lambs quarters, germinate in spring, grow throughout summer and are gone with the arrival of cold weather.
Biennial types – Biennial weeds complete their life cycle in two years, germinating and forming rosettes their first year and producing flowers and seeds their second year. Examples of these types include: bull thistle and garlic mustard.
Perennial types – Perennial weeds return every year and normally produce long tap roots in addition to seeds. These weeds, which include dandelions, plantain, and purple loosestrife, are the most difficult to control.
