- 1). Spray the weeds with herbicide, many of which are labeled for specific types of weeds such as broadleaf weeds like clover, while others are multi-purpose weedkillers. Some weedkilling herbicides will not harm grass, while other herbicides will kill any plant they touch. Decide which type is best for your lawn and choose accordingly. Spray the weeds and give the herbicide a day or two to kill the weeds before proceeding to the next step.
- 2). Pull the weeds by hand. This can be time-consuming but is effective, so long as you pull up the root system with the aboveground part of the plant. Grasp the base of the weed as close to the ground as you can, then pull it from the soil. As the root system is pulled free from the soil, lower your grip and pull as much of the root system out of the ground as you can. Pulling by hand is effective for weeds that are resistant to weedkiller spray, are close to your flowers or lawn plants or for very thick patches of weeds.
- 3). Apply mulch around your plants and bushes. Mulch will help smother weeds and kill them by denying them the sunlight they need to grow. Mulching also prevents weed seeds in the soil from germinating. Remove or kill all of the weeds in the area, then spread a 1- to 2-inch layer of mulch around your plants and flowers.
- 4). Mow your lawn frequently. Set your mower depth so you do not cut more than a third of the height of the grass; you want to keep the grass density high. Cutting too much off at once lowers the density and give weed seeds a better chance to germinate and grow. You may need to mow your lawn every three to five days during spring and summer, when the grass grows rapidly.
