How to Remove Lawn Weeds

By Lauren Wise ; Updated September 21, 2017

Even if you work hard on making your lawn look good, weeds can easily sprout up and ruin your work. With all the chemicals and herbicides available nowadays, it is hard to know what won't harm your lawn. The key is to make sure your lawn is strong, with deep roots to prevent any weeds. To ensure this, pull up weeds or trim them when they are young, and only use herbicide if it is absolutely necessary.

Make sure your lawn is growing to be strong with deep roots. To ensure this, make sure that your lawn gets about an inch of water per week. Many people make the mistake of watering their lawn every day or two, but doing this makes the lawn have shallow roots, giving dozens of types of weeds the ability to grow. Once a week, your lawn should have one deep soaking.

Use a good fertilizer for your lawn. Depending on the type of grass you have, as well as the weeds you have problems with, your choice of fertilizers may vary. Make sure to follow the directions exactly in order to get the right balance for your lawn. Fertilizing effectively crowds weeds out, but too much can make crabgrass flourish, while too little will make your lawn grass weak.

Get rid of weeds already present in your lawn. The best way is to pull the weeds out with your hands while they are young. Grasp the weed at the base where it goes into the ground, and pull it out firmly and upright to get out the roots. For weeds like dandelions, get a dandelion removal tool to make sure the whole root gets removed, then reseed the hole with grass seed. Use pruning shears for larger weeds, and make sure to sanitize any affected tools before using them on other plants.

Use an herbicide if absolutely necessary. This should be used when weeds are out of control in your lawn, or if they keep growing back in large numbers. Choose a selective herbicide for certain weeds so it doesn't harm your grass. Still, avoid getting the herbicide on other plants or a lot of your grass. Apply a pre-emergence herbicide twice a year, which helps to kill certain weeds before sprouting.
