When to Apply Crabgrass Preventer in Michigan
Crabgrass, the notorious intruder in many Michigan lawns, has a knack for disrupting the beauty and uniformity of our lush green landscapes. But fear not, dear Michigan homeowners! There is a secret weapon at your disposal – the mighty crabgrass preventer. However, to effectively combat this tenacious weed, timing is everything. So, let’s delve into the perfect timing for applying crabgrass preventer in our beloved state.
The Role of Weather in Crabgrass Emergence
Before we uncover the opportune moment to wield your crabgrass preventer, let’s first understand the role of weather in crabgrass emergence. Michigan experiences varying climates across its different regions, resulting in diverse weather patterns. This means that one size does not fit all when it comes to crabgrass prevention.
Understanding Soil Temperature
To determine the optimal time to apply crabgrass preventer, keep an eye on soil temperature. As a rule of thumb and to make things simple, it’s advisable to apply the preventer when the soil temperature reaches 55°F. This magical number is the sweet spot when the majority of crabgrass seeds start their germination process.
Early to Mid-Spring: Pre-Emergent Crabgrass Control
In Michigan, usually by early to mid-spring, when the soil temperature hovers around that delightful 55°F mark, crabgrass-loving homeowners spring into action. And rightly so! This is the ideal time to apply a pre-emergent crabgrass preventer. By doing so, you create a protective barrier that stops crabgrass seeds from sprouting, effectively nipping them in the bud.
Considering the Type of Crabgrass Preventer
When selecting a crabgrass preventer, consider whether you opt for the pre-emergent or the post-emergent variety. The pre-emergent variety, as the name implies, prevents crabgrass from sprouting, while the post-emergent type combats crabgrass that has already started to invade your lawn. For optimum results, it’s best to apply the pre-emergent preventer at the recommended time.
Avoiding the “Too Early” Temptation
Ah, the eagerness to get ahead of the game! You might be tempted to jump the gun and apply the crabgrass preventer as soon as winter fades away. But hold your horses! Applying the preventer too early may render it ineffective, as its potency wanes over time. Remember, timing is key. So, don’t rush and let spring settle in before unleashing your crabgrass-preventing powers.
Timing and Other Considerations
Apart from soil temperature, it’s crucial to consider a few other factors relating to timing:
Soil Moisture
Ensure that the soil is not overly saturated or waterlogged when you apply the crabgrass preventer. Moist but not overly wet soil provides the ideal conditions for the preventer to work its magic.
Rainfall and Irrigation
If rain is in the forecast within 24-48 hours after applying the preventer, it’s best to hold off for a bit. Heavy rainfall or excessive irrigation can potentially wash away the preventer, rendering it less effective.
Continuing Vigilance
While the initial application of crabgrass preventer is crucial, don’t rest on your laurels. Keep monitoring your lawn throughout the summer and, if necessary, apply a post-emergent crabgrass control treatment to tackle any stubborn invaders.
Crabgrass may be a formidable foe, but with the right timing and a well-executed plan, you can maintain a lawn that would make your neighbors green with envy (pun intended!). So, dear Michigan homeowners, remember to wait for that soil temperature to hit 55°F, resist the temptation to apply too early, and keep an eye on the weather forecast. Armed with these tips, you’re now equipped to conquer crabgrass and reclaim the splendor of your Michigan lawn!
FAQ: When to Apply Crabgrass Preventer in Michigan
Is it too early to put down crabgrass preventer?
In Michigan, timing is crucial when it comes to applying crabgrass preventer. While it’s essential to catch crabgrass before it starts to grow, applying the preventer too early can result in it losing its efficacy by the time the crabgrass starts to germinate. Therefore, it’s generally recommended to apply crabgrass preventer when soil temperatures consistently reach around 55°F (13°C). You can check the soil temperature using a soil thermometer or by consulting your local agricultural extension service.
Can you put down crabgrass preventer and fertilizer at the same time?
Yes, you can apply crabgrass preventer and fertilizer at the same time, which is convenient for homeowners looking to tackle multiple lawn care tasks simultaneously. Many crabgrass preventers already include a balanced fertilizer, so you can achieve both weed prevention and nourishment for your lawn in a single application. However, if you prefer using separate products, it’s best to apply the crabgrass preventer first and then follow up with the fertilizer.
Should I mow before pre-emergent?
Yes, it is advisable to mow your lawn before applying pre-emergent herbicides. Mowing the grass to a shorter height helps the pre-emergent reach the soil surface more effectively, ensuring better coverage and weed prevention. Additionally, removing excessive grass height will prevent the herbicide from being diluted or trapped in tall grass blades.
Is it too late for crabgrass preventer in Michigan?
Timing is crucial when it comes to crabgrass preventer, but if you’ve missed the window of opportunity, it’s not necessarily too late to act. Although applying crabgrass preventer early in the season is ideal, you can still apply it later, even after some crabgrass has started to germinate. Keep in mind that the preventer will be less effective against mature crabgrass plants. However, it will still provide some control and prevent future crabgrass growth, making it worth considering if you’ve missed the optimal timing.
What time of year do you put pre-emergent on your lawn?
The ideal time to apply pre-emergent herbicides on your lawn is in early spring, right before crabgrass starts to germinate. In Michigan, this usually occurs when soil temperatures consistently reach around 55°F (13°C). Applying pre-emergent at this time creates a barrier that prevents crabgrass seeds from sprouting, giving your lawn a head start against these pesky weeds.
What is the best crabgrass killer?
The best crabgrass killer for your lawn is a pre-emergent herbicide specifically designed to target crabgrass before it germinates. Look for products that contain active ingredients such as dithiopyr or prodiamine, which effectively prevent the growth of crabgrass seeds. However, if crabgrass has already appeared in your lawn, post-emergent herbicides containing ingredients like quinclorac or fenoxaprop-p-ethyl can help control and eliminate existing crabgrass plants.
Can you apply pre-emergent too early?
Yes, applying pre-emergent herbicides too early can reduce their effectiveness. It is crucial to time your application correctly, as pre-emergents form a protective barrier on the soil surface that prevents crabgrass seed germination. Applying the herbicide too early may cause it to break down before the crabgrass starts to sprout, leading to ineffective weed control. Be sure to monitor soil temperatures and follow the recommended guidelines for the specific product you are using.
How do I get rid of crabgrass in early spring?
To combat crabgrass in early spring, incorporating a two-pronged approach is essential. First, apply a pre-emergent herbicide before the crabgrass starts to germinate. This prevents the seeds from sprouting and taking over your lawn. Secondly, if some crabgrass manages to emerge, manually pulling or spot treating with a post-emergent herbicide can help eliminate the stubborn weeds. Remember to follow the instructions on the packaging and use herbicides responsibly.
What temperature should it be to apply pre-emergent?
When it comes to applying pre-emergent herbicides, soil temperature is a crucial factor to consider. As a general guideline, it’s recommended to apply pre-emergent when soil temperatures consistently reach around 55°F (13°C).

Wait for the grass to dry before applying crabgrass preventer to ensure better absorption and effectiveness.
At what temperature does crabgrass germinate?
Crabgrass germination primarily occurs when soil temperatures consistently reach around 55°F (13°C) or higher. This usually happens in early spring in Michigan. Crabgrass seeds lie dormant until favorable conditions are present, including warmer soil temperatures. By applying pre-emergent herbicides before crabgrass germination, you create a barrier that prevents the seeds from sprouting, giving your lawn a fighting chance against this pesky weed.
Should you pull out crabgrass?
If you spot crabgrass in your lawn, it’s generally recommended to remove it promptly. Manual removal is best done when the plants are young, as crabgrass spreads rapidly and produces abundant seeds. Carefully pull out the entire plant, including the roots, to prevent regrowth. However, manual removal may not be practical for large infestations, and using herbicides, whether pre-emergent or post-emergent, can be an effective alternative for controlling and eliminating crabgrass.
When should I spread crabgrass preventer?
To effectively prevent crabgrass, it’s recommended to spread crabgrass preventer in early spring before the seeds start to germinate. Timing is crucial, and usually, this occurs when soil temperatures consistently reach around 55°F (13°C). It’s important to follow the instructions on the product packaging and apply the preventer evenly over the entire lawn. Remember to water the area after application to ensure activation and effectiveness.
When should I apply crabgrass preventer in Michigan?
