How to Deal With Crabgrass in Your New Hampshire Lawn

Unfortunately, crabgrass is a common problem we see here in New Hampshire and all over the region. Crabgrass is a coarse, clumpy ‘grass-like’ weed that grows in the summer and can do a number on your turf. It does this by beating your grass to the punch when it comes to absorbing water and other valuable nutrients. The good news is that there are several ways of getting rid of it; but most importantly, it’s just best to get out in front of it before it becomes an issue. Here are some ways you can deal with crabgrass in New Hampshire if you experience an outbreak on your property.

What Does Crabgrass Look Like?

There are a few different kinds of crabgrass, but they all share more or less the same characteristics. They look like coarse, light green clumps of grass. The species gets its name large in part because the stems look like a crab’s legs, thus - crabgrass. 

How Do I Get Rid of Crabgrass?

There are a few ways that you can get rid of crabgrass in New Hampshire. The first is the good, ole-fashioned weed-pull; ripping the plant out roots and all. While this will work to kill the crabgrass, it can be a bear to rip out of the ground sometimes, so be ready for a workout! If you want to cheat a bit, spray some water on the soil to loosen up the ground to make it easier to pull out. Once that’s done, you’ll want to immediately seed the bare area. Another way to prevent crabgrass is to apply pre-emergent in the spring before it sprouts. That being said, be careful about what kind of pre-emergent you choose to use, as certain kinds of pre-emergent solutions are used specifically for a certain type of weed. 

If it’s too late for that, you’ll be in a different mode. To kill it off over the course of the season and prevent it from coming back - be sure to do the following:

  • Keep your grass around 3 inches tall when you mow it. The lower you go, the more likely you are to create conditions for crabgrass and other weeds to flourish. Higher cuts, while they require a little more maintenance - will discourage crabgrass growth. 
  • Every time you mow, don’t cut more than ⅓ of your grass at a time. 
  • Deeply water your grass 1-2 times a week. Try to get a solid inch or two soaks.
  • Fertilize your lawn to keep it healthy down to the roots. The deeper a grass’ root system goes, the stronger it will be.  
  • Crabgrass will naturally die in the fall as the temperature dips. Once you hit that colder weather, lay some pre-emergent down. Come springtime, you should be in the clear. 

How Do I Kill Crabgrass Before It Starts?

A hidden fact is that crabgrass actually dies on its own in the fall. So unless you think it’s really important, you can essentially wait out the crabgrass and wait for it to die off. This type of weed won’t be able to live through the harsh New Hampshire weather. However, you will need to do one critical thing before the start of the next growing season and that’s applying a pre-emergent in the Spring. Pre-emergent will help prevent crabgrass from ever growing and will make it easier for you to take care of your lawn.
