Utah Ornamental and Turf Pest Control Practice Test

The primary characteristic of winter annual weeds is that they germinate in the fall and typically die in the spring. This life cycle allows winter annuals to take advantage of cooler temperatures and moisture in the autumn for germination. They grow during the fall and winter months, often becoming established before the onset of harsh winter conditions. Once spring arrives, these weeds mature and set seed quickly, completing their life cycle before the hotter summer months, which can be detrimental to their growth.

This growth pattern enables them to outcompete other plants for resources during the cooler parts of the year. Understanding this life cycle is crucial for effective weed management and control strategies, as targeting them during their active growth period can help prevent them from establishing seed banks for future seasons. This is key in maintaining the health and aesthetics of ornamental and turf areas.
