Over the growing season, you will need to perform some weed maintenance in your lawn so that the appearance is more uniform and the grass is healthier since there is less competition for nutrients and water.
Use a Pre-Emergent
In the spring, especially if you are trying to revitalize a lawn that has been left untended for a while, start by using a pre-emergent. This is especially necessary for stubborn weeds like crabgrass that can cast out thousands of seeds every year. A pre-emergent works by killing plants that are newly germinated. You will likely need to do it at least twice to catch any weed seeds that escaped the last time.
Practice Proper Lawn Care
As the season progresses, manage your lawn so that it is in tip top shape to help keep the weeds away. When your grass is doing well, it is much harder for weeds to become established. Water less frequently for longer lengths so the roots become firmly entrenched and can access water easier if needed. Don’t “scalp” your lawn by cutting it too close to the ground, which can stress your grass out. Fertilize as needed.
If there are not many weeds, try to remove them by hand with a tool such as a dandelion digger. Non-grass weeds (known as broadleaf weeds) can be controlled using a herbicide formulated specifically for them, since they metabolize differently than grass plants. Read the label to make sure you are using one that will not harm your lawn itself.
Fall Weed Removal Is Possible
You can also treat weeds in the fall. They are getting ready for the coming harsh winter and focus more on storing food in their roots. There is a better chance that they will take up chemicals like pre-emergents. This will help you keep your lawn weed free in the coming years.
