Henbit & Dead Nettle Prevention

-To quickly improve the look of the Lawn simply mow regularly even through the winter to cut the weeds back making it less visible.

-Crowd out the weed by regularly feeding your lawn, and re-seeding.

-Mow your lawn at proper height. Cut the grass as high as possible during the grow season to allow a deeper root system to promote a healthier lawn and further smother out, not just henbit, but most other weeds also.

-Use pre-emergents in the fall to eliminate the weed before it germinates. We usually do this in October-November.

-If have a small patch in your yard and prefer not to use chemicals it is possible to pull these weeds by hand, just make sure you pull the entire root out as well!

Farmers have been using glysophate to kill the weeds on the past but in the later years the weed has become more and more resistant to the poison, resulting in the use of more toxic chemicals such as 2,4-D to kill these winter weeds before the crop is planted in spring. See the interesting LSU Agg article here.

Conclusion

Now that the plant has flowered it is harder to get rid of but the good news is this weed will be gone as soon as the temperatures start to to rise in the Spring and Summer season. The bad news is that it will then have even more seeds in the ground underneath ready to begin the process all over again next year.

  1. Do you use regular mowers in Broadmore? These lots are too small for riding mowers.
