Task of controlling weeds doesn't end with summer

Winter annuals germinate in the fall and the next spring they flower, produce seed and die before the summer heat. Examples are downy brome, chickweed, some mustards and wild oats.

Biennials have two year cycles. They grow vegetatively (without flowering) the first year. The next season they flower, produce seed and die. Thistles, mullein and hound tongue are biennials.

Perennials live three years or more. They flower and set seed without dying. Usually the tops die back in the winter but resume growth in the spring. Examples are quack grass, field bindweed, dandelion and plantain.

Knowing about weeds helps you control them. Next week's column will focus on specific weeds and how to best control them.
