• Chickweed is said to have medicinal properties, and this may be so, but when it is infesting your yard, it isn't appealing. This weed is difficult to remove from lawns and generally takes several applications of herbicides to remove the plants. If you prefer not to apply chemicals to your lawn, you are limited as to how you can remove the chickweed.
  
  

Pull It Up

• Wait for a dry, cool day. You want to kill the chickweed before the plant blooms. Pull up the weeds by the roots as much as possible. Wear gloves so you don't hurt your hands, and grasp the plant as close to the base as you can. Pull straight up. Cover ground locations, where you pulled up the chickweed, with mulch to keep the plant from growing back.
  
  

Vinegar and Plastic

• Spray large areas of chickweed with white vinegar. Be sure not to get it on other plants. Cover the large area of chickweed with plastic after you spray, and leave it through the summer. The lack of light, heat from the plastic, vinegar and lack of water will kill the weed.
  
  

Salt Water

• If all else fails, spray the chickweed with salt water. This will kill the weed, but will also prevent other vegetation from growing in its place for quite a while. After the weed is dead, you can improve the soil by scooping off the top layer, tilling and watering the soil, and then mixing in organic material and new top soil.
