How to Identify Crabgrass In a Lawn – Crabgrass vs Coarse Tall Fescue – Problem Grasses

Use a post-emergent herbicide labeled for crabgrass. If you already have a crabgrass infestation, then a chemical treatment may be necessary to tackle the problem. All lawn weed herbicides are not made the same. Some will kill your regular grass and other common weeds. Make sure you read the label. Herbicides made to target crabgrass will be in a liquid form. It is meant for spot treatment and not for a broadcast application. Follow the directions on the label of the product for proper safety protocol.

Soil Temps Are Crucial

Crabgrass starts to germinate when your soil temperature hits 55 degrees. The best thing you can do is find out when your soil temperature usually hits 50 degrees and apply your crabgrass pre-emergent then. If you apply when soil temps are at 50, by the time it hits 55 the pre-emergent will already be in your soil.

Youre probably wondering how youre supposed to know when your soil temperature is 55 degrees. Luckily, there is a great site called Green Cast Online.

All you have to do is go to the site and enter your zip code. Look at the five day average and when it hits 50 degrees its time to throw down your first application.

About 5-6 weeks later you want to apply another round of pre-emergents as soil temps approach 70.

Once soil temps go above 80 degrees crabgrass germination comes to a halt. Adding a pre-emergent at this time wont be very effective. I should point out that at the end of summer as soil temps fall back down to 70 degrees there are fall germinating broadleaf weeds that can pop up. Thats why I recommend a third application of pre-emergents heading into fall.

Why Is Crabgrass A Problem In Lawns

Crabgrass is an annual lawn weed that appears each year. Its seeds germinate in the spring and summer, and even if you successfully blocked and removed crabgrass last year, you could be fighting it again this year.

Crabgrass seeds are incredibly persistent.

In fact, un-germinated crabgrass seeds are able to stay in the soil for as many as 3 years before they sprout!

Germination of crabgrass takes place when the temperature of the soil three inches down gets to between 55°-65°F for five days in a row.

During the growing season, one crabgrass plant is capable of producing as many as 150,000 seeds. This is one reason why crabgrass is one of the most challenging weeds to get under control for many homeowners.

Once you have crabgrass growing on your lawn, youre sure to see more later on.

Before you know it, youll end up with a significant problem, which is why so many people want to know how to kill crabgrass naturally or otherwise.

How To Prevent Crabgrass In The Spring

It is far easier to stop crabgrass in the spring before it becomes a nuisance in the summer. Crabgrass seeds can start to germinate in the spring once the soil reaches 55 °F, so crabgrass preventers, like Scotts® Turf Builder® Halts® Crabgrass Preventer with Lawn Food, should be applied in early to mid-spring before the crabgrass starts to develop. If youre also dealing with broadleaf weeds, use Scotts® Turf Builder® Triple Action instead. Not only does it prevent crabgrass for 4 months and feed your lawn, but it also kills weeds like dandelion and clover. Just seeded your lawn? Opt for Scotts® Turf Builder® Triple Action Built For Seeding instead. It protects new grass from crabgrass and other weeds while helping it get established more quickly and grow thicker.

Best Crabgrass Killer That Wont Kill Grass

  • Crabgrass is a grassy weed thats tough to kill with most combination herbicides. In fact, some post-emergent herbicides can damage your lawn while acting on crabgrass. So, whats the best crabgrass killer for lawns that probably wont kill grass?

    The best crabgrass killer for lawns is Tenacity Turf Herbicide. It is a safe selective systemic herbicide that wont kill lawn grasses such as KBG, perennial ryegrass, tall fescues, and centipede grass. Tenacity can be applied at seeding or on established lawns. Do not apply it on paspalum, kikuyu grass, and bermudagrass.

    Below is a review of the best crabgrass killers for lawns with different turfgrasses to help you find a great grassy weed killer that wont harm your lawn.

    Apply A Double Dose Of Herbicide To Crabgrass Hotspots

    • Limit crabgrass growth in areas like driveways, sidewalks and curbs or on south-facing banks by doing a targeted double treatment when necessary. These areas absorb a lot of heat during the summer months, which makes them more susceptible to crabgrass.
    • After you’ve treated your entire lawn, go back and make another pass about six to eight feet wide, along hotspot areas . This will help keep crabgrass from taking hold.

    How To Prevent Crabgrass Germination

    • Mow at frequent intervals to keep the grass at a consistent length. Check the recommended mowing heights for your type of grass and cut your lawn at the highest recommended setting. Crabgrass requires plenty of light to germinate, so keep the grass as thick and long as possible to create shade near the soil surface. Cutting your lawn too close produces patches where crabgrass and other weeds can germinate.
    • Remove no more than one-third of the grass blade at one time when mowing. Removing more not only allows more light to reach weeds, it also can injure the grass.
    • In an established lawn, water in long, heavy intervals rather than shallow, frequent ones. Watering on an irregular schedule and only when needed promotes deeper root growth that’s essential to healthy turf grass. Remember that most established lawns require about one inch of water per week from rain or irrigation. If your lawn is newly-seeded, water in shallow, frequent intervals until the grass gets established.
    • Fertilize your grass at least once a year, following the package instructions.

    How To Remove & Prevent Crabgrass

    • You may pull what you think is the plant, but fail to get the stems that have rooted at the nodes. Secondary stems will sprout off the main stem, a foot or two away from the main crown.
    • Hand weeding and hoeing are effective measures of controlling crabgrass, and mulching will help, as long as you spot and remove any seedlings that sneak through the mulch.
    • Crabgrass grows best in acidic soil, so reducing the soils pH by adding lime, you will reduce the level of acidity and make it harder for it to thrive.

    Controlling Crabgrass In Your Lawn

    Crabgrass? Or tall fescue? How to kill weeds in lawn.

    Along with goosegrass, crabgrass is a pervasive weed found throughout the continental United States that many lawn owners struggle to control. Appropriately named, crabgrass grows close to the ground and has branching stems resembling crab legs. Due to this growth habit, crabgrass is very adaptable to short mowing heights and can continue to produce seed even when mowed as low as ½ an inch. Crabgrass is also quite drought tolerant and thrives in the hot conditions that the summer brings.

    As an annual weed, crabgrass remains present in the landscape for one growing season, which usually begins in the late spring and early summer after the soil temperature has reached a temperature of 55 to 60 degrees for over five days. Once the plants germinate, they will continue to grow until the days begin to shorten, causing them to enter a reproductive stage. During this time, plants produce seed until the first frosts of the fall hit and knock them out. Even if crabgrass isnt visible in your lawn during the fall and winter, if the plant was able to set seed, prepare begin fighting it again come warmer weather.

    Crabgrass Non-Chemical Control

    There are many control options available to help ensure that this season is that last time crabgrass invades your lawn. Some natural prevention methods to strengthen your lawn include:

    What Is The Mimosa Tree Looking Weed In My Yard

    Chamberbitter .Nancy Loewenstein, Auburn University,

    It is a summer broadleaf weed called Chamberbitter. In fact, one of its nicknames is Little Mimosa weed. It is a broadleaf weed that is thought to have been introduced from Florida from pine straw about 15 years ago. It is a prolific seeder and has done well moving around the Triangle from straw and other means. It typically germinates in mid to late summer and usually appears around pine straw and birdfeeders first. It will grow straight up like a tree until mowed. Chamber Bitter spreads by seed. Seed pods are under and along the leaf branches and contain hundreds of seeds per plant.

    It is a difficult broadleaf weed to control with the available broadleaf weed control products. We identify our customers that have this broadleaf weed and try to make multiple weed control applications to gain some control on spreading.

    Spot Treat To Kill Crabgrass

    While prevention is definitely the best method for managing crabgrass, it is likely you will still have some clumps of crabgrass that find a way into your turf. It is usually in the most vulnerable locations within your lawn.

    The best way to kill crabgrass that is already established is to spot treat using a liquid, lawn safe herbicide such as Ortho Weed B Gone Plus Crabgrass Control. A product like this is easy to apply and best of all it will kill crabgrass without killing your lawn surrounding the crabgrass.

    I recommend going out and walking your lawn once a week to spot treat new clumps of crabgrass that pop up.

    If you have a more serious problem, meaning crabgrass is more mature or widespread, then I recommend using a product called Tenacity. Tenacity is a more professional product that works a little differently. It blocks photosynthesis from occurring in lawn weeds.

    It is a selective herbicide so it will kill crabgrass and other lawn weeds without killing your lawn. If you have crabgrass everywhere then you can blanket spray your entire lawn with Tenacity.

    When spot treating or blanket spraying, make sure conditions are dry so the herbicide sticks to the grass blades. Also, make sure you dont apply before rain, or right before mowing. You want the herbicide to have time to do its job.

    With enough persistence, you will eventually win the battle as the crabgrass dies off and your lawn fills in from routine fertilizer treatments.

    How To Get Rid Of Crabgrass In The Lawn

    Crabgrass loves hot, dry conditions. Take care of it before it becomes a problem.

    Crabgrass gets its name because it grows low to the ground with stems that radiate out from the center of the grass clump, resembling crab legs. Seeds begin to sprout in mid-spring, as soon as the soil temperature reaches 55 °F, and crabgrass can quickly become a problem during the summer because it is able to grow vigorously in hot, dry conditions. Crabgrass is an opportunistic annual weed that will grow in the thin and bare spots in your lawn. Before it dies in the fall, a single crabgrass plant produces thousands of seeds that can germinate the following spring.

    How do I control crabgrass in my lawn?

    Controlling Crabgrass Before it Comes Up

  • Timing is essential when using pre-emergent herbicides.
  • Reminder About Crabgrass And Broadleaf Weeds This Time Of Year

    It is not uncommon to have some crabgrass germinating in the lawn around the end of July through August. The pre-emergent applied earlier in the year will start to degrade and break down. Generally, Crabgrass will germinate in areas with thin turf, along roadways and other hard surfaces, and in high spots of the lawn. Pre-emergent breakdown is especially important in Fescue lawns because seeding needs to take place starting at the end of August to mid-October. Fescue seedlings would not be able to survive with pre-emergent still bonded to the soil particles.

    You also may notice an increase in broadleaf weed germination at this time too. Pre-emergent Crabgrass control also helps control broadleaf weed germination.

    Bermuda And Zyosia Lawn Tips

    • Pre-spring : In January, Apply pelletized lime to the soil as needed. Then, apply a pre-emergent without fertilizer in February. We recommend Scotts Halts Crabgrass Preventer. March is the time to spray broadleaf weeds such as dandelions, clover, and chickweed. Weed-B-Gone Max and Fertilome Weed-Free Zone are useful for this. However, Fertilome Free-Weed Zone works best in temperatures below 70 degrees.

    • Spring : In April, fertilize the soil with a high nitrogen fertilizer, like Ace Weed and Feed. Continue to spray for broadleaf weeds in May using Weed-B-Gone Max.

    • Summer : This is the best time to over seed! Re-apply a pre-emergent in June. However, if you are overseeding, skip this treatment. Use Fertilome Weed Out with Q or Ortho Weed-B-Gone Max with Crabgrass Control in July to kill crabgrass. If you want to green up your lawn for the summer months, Milogante is a safe, non-burning fertilizer that can be applied during this time.

    • Fall : If you arent over seeding with Rye for the winter, repeat the pre-emergent in September. Make Sure to remove any leaves promptly, and apply winterizer in October. We recommend Ace Green Turf Winterizer and Scotts Super Turf Builder Winterguard.

    • Other Tips for Bermuda and Zyosia Lawns: For best results, use a hand-held spreader for Bermuda and Zyosia lawns. Over seed Bermuda and Zyosia lawns with annual rye in early fall to enjoy a green lawn during the winter. Water your lawn in the morning to avoid damage from fungus and disease.
