Yellow nutsedge is perennial weed that plagues many lawns here in the CSRA. Unfortunately because it is a perennial, this sedge can not be controlled with preemergent herbicides. It seems to do well in poorly drained areas and compact soil in which desired grass may struggle.
Best cultural practices are to cut your lawn high and water your lawn deeply but less frequently, making the area less desirable to the sedge. Read our blog article on watering practices to learn why deep watering is a better choice for your lawn.
You can accompany these cultural practices with fertilization which helps your grass out compete the sedge, and chemical controls which help kill the plant over time.
If you want a pristine lawn we are very close to our fall preemergent window here in the CSRA. If you've lived here for a year or more, you've likely heard of and seen poa annua, also known as annual bluegrass. Your fall preemergent application will ensure little to no poa annua germinate and develop in to the adult plant, which can detract from the curb appeal of your lawn.
There are several products on the market but if you want the best, Specticle Flo is the only way to go. This is the industry go to for those companies willing to spend a little extra for a premium product. If you want to apply this product yourself, ensure you do so before your soil temperatures drop below 70 degrees.
Feel free to contact us with any questions. We'd love to help in any way we can!
Unless you plant a winter rye or some other cool season grass, lawns will begin going dormant over the next couple of months. Although weather determines when warm season grass goes dormant, we typically see this change no later than mid November.
A few best practices would be to cut your lawn low for the winter, typically 1.5 to 2 inches in height. This reduces the chance for fungal problems over the winter. Once your lawn goes dormant, you can stop watering as well. This saves money and also helps in prevention of fungal growth.
If you have any weed problems that show up during or continue through dormancy, this is a great time to address them because you can use glyphosate for those hard to kill weeds like dallisgrass without harming your bermuda lawn.
We hope this information is useful and if you have any questions feel free to contact us at 706-941-6600.
Although we love to be able to provide methods in which to control weeds without chemicals, poa is one that you really need to apply a fall preemergent to control. Because it can become such an eyesore we felt it was important enough to discuss in our cultural controls section.
There are many products on the market available to homeowners such as Prodiamine but the most effective preemergent for poa annua control is Specticle Flo. It is rather expensive, selling for around $300 for their smallest bottle, but is also a prime example of the saying, you get what you pay for.
If you prefer to have a professional treat your lawn, you're in luck, we use Specticle Flo and are currently running a signup discount for those who start service before October 1st 2021.
Give us a call so we can get this preemergent applied before soil temperatures drop below 70 degrees.
