•Summer Annuals: Germinate from seed in the spring.
•Winter Annuals: Germinate from seed in the fall.
•Biennials: Germinate from seed in the spring and summer.
•Perennials: Germinate in spring when young and actively growing.

Maximize The Kill Opportunity
Since the main objective is to prevent weeds from producing and spreading seeds, they must be killed early in the life cycle. Usually the best time of application is when plants are young and vulnerable.

Less Is Better
Minimizing is the key to proper application. Always use the least amount of herbicide necessary. Minimal applications provide enough herbicide to completely kill weeds without causing dangerous environmental or human hazards. Younger weeds also require less herbicide for total kill.
