In this part of the video, Chad from Turf Organics discusses poa annua grass, also known as annual bluegrass, a common weed found in lawns and landscapes. He highlights that poa annua can produce up to 100 seeds per plant and the seeds can remain dormant in the soil for years, making it challenging to control. Chad explains that poa annua germinates in late fall and early spring, emphasizing the importance of timing for effective control. He mentions that while there is no effective post-emergent herbicide for poa annua, using pre-emergent herbicides in early fall and early spring can help prevent the seeds from germinating and spreading.

In this segment of the video, the key points include using pre-emergent herbicides and implementing cultural practices to prevent Poa annua grass growth. Recommendations include avoiding over-fertilization with phosphorus, not over-watering shady areas, maintaining a thick and healthy lawn, and cleaning equipment to prevent spreading seeds. It’s noted that Poa annua doesn’t thrive in heat and tends to die out naturally in temperatures consistently above 80 degrees. Additionally, the segment emphasizes that pre-emergent control may take several years of consistent applications to fully eliminate the weed and that dormant seeds can remain in the soil for years. The advice given is to actively pull out Poa annua when seen and apply timely pre-emergents for future prevention. Persistence, consistency, and maintaining a healthy lawn are highlighted as essential for effectively managing Poa annua.
