2. Clover (Trifolium spp.)


  • Small, trifoliate (three-leaf) plants with white or pink flowers.
  • Often found in lawns with low nitrogen levels.


  • Cultural: Improve soil fertility by applying a nitrogen-rich fertilizer.

  • Chemical: Use a selective broadleaf herbicide when the plants are actively growing.

4. Winter Grass (Poa annua)


  • Annual grass with light green leaves and a tufted growth habit.
  • Thrives in cooler, moist conditions and can form dense mats.


  • Cultural: Improve lawn drainage and avoid overwatering.

Hand-pulling or digging out weeds can be effective, especially for small infestations. Ensure you remove the entire root system to prevent regrowth.

4. Chemical Control

When using herbicides, choose products that are specifically formulated for the type of weeds you are dealing with. Follow the manufacturer’s instructions carefully and apply the herbicide at the recommended time for best results.
