A good preemergent herbicide can help keep new weeds from appearing.
When you are doing your spring lawn assessment, note whether there are any weeds present in your lawn. In addition to removing these, you may want to use some preemergent weed control before the growing season really gets into full swing.
What Is a Preemergent Herbicide?
Lawn chemicals are formulated to be able to affect plants in different ways, so it is important to read the label to make sure that you are buying the right kind. In the case of a preemergent herbicide, it is applied early in the growing season and stops weed seeds from germinating. If there are already weeds present, they will not be effected and will need to be removed using another method.
You also need to make sure that you sow any new grass seeds before you put down this type of chemical. It will be able to affect any seeds that are present and your hard work would be for nothing. Make sure that you do your lawn reseeding and preemergent applications a few months apart from each other for the best chance of success.
When Do I Use Preemergent Weed Control?
Now is about the right time to start putting down your herbicides. You want to do it once the temperatures have started to rise a bit (mid-50s to 60s or so), but not too much farther past that since seeds present will start to sprout. You can also do some in early fall, which will help keep down the weeds in the following growing season.
