How To Identify Crabgrass
Crabgrass is easily known by most people, it is most noticeable by its wide leaf blade and grass-like appearance.
This grass, however, will send out tough stems with fingers of seed heads at its tips. Crabgrass will become most prominent when its leaf blades grow faster than the surrounding lawn and when it reaches out and become taller than the other turf.
The seed production of Crabgrass is extremely prolific.
Every season, a single weed can send out thousands of seeds, so its easy to see how it can quickly spread and take over and ruin an entire lawn.
How To Kill Crabgrass And Prevent It From Returning
Once crabgrass gets started in your lawn, those coarse, unattractive weeds seem to live and spread forever. But unlike lawn weeds that do live several years, crabgrass plants only live a single year. What they do in that year, however, has long-lasting consequences for your lawn. Understanding how crabgrass works and how to break its cycle can help you get rid of crabgrass and keep it gone.
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.

Killing Grass Naturally With Castile Soap
Another easy and equally appealing recipe to try substitutes traditional dish soap with a more natural version. A vegetable-based cleaner, Castile soap adds the same surfactant properties as regular soap using all-natural elements. We added some essential oils to aid in the weed-killing process.
Natural Weed Killer with Castile Soap
- 1 ¾ cups white vinegar
- ¼ cup liquid Castile soap
- 3 drops wintergreen essential oil
- 3 drops clove essential oil
- 3 drops cinnamon essential oil
- 3 drops orange essential oil
While these essential oils smell great, they do have a purpose in weed control, as well. Clove is one of the best ways to control weeds like crabgrass since it contains a chemical called Eugenol that damages cell membranes on plants.
Similarly, oils like cinnamon are natural fungicides that kill seedlings before they have the chance to spread. These same powerful treatment methods also apply to weeds like crabgrass.

How To Get Rid Of Crabgrass
What Is Crabgrass?
Crabgrass is one of the most tenacious weeds that a gardener has to contend with. Crabgrass control can feel like a running battle with the right approach, though, you can get the better of this common nuisance plant.
Crabgrass is the common name for Panicum sanguinale, a fast-spreading and hard-to-eradicate weed. Named for its low growth and crooked stems that resemble crab’s legs, crabgrass creates ugly bald spots on lawns and grassy areas and crowds out crops and flowering plants. When you mow your lawn too closely , crabgrass reveals itself as thin, bare patches in the grass. Crabgrass thrives in hot and dry conditions, a characteristic that often gives it an advantage over other grass species and allows it to take over.
Crabgrass doesnt only spread through growth it is also a prolific seed producer. It only lives for a single season and dies off in the winter, but thousands of crabgrass seeds can live in the soil and produce many more weeds in the spring.
How to Get Rid of Crabgrass
The best way to get rid of crabgrass is to kill or physically remove every plant from the soil. This can be easier said than done, given the spreading habit of crabgrass and the many seeds it produces.
If there are only a few crabgrass patches in your lawn or garden bed, you can get rid of this tenacious weed by hand-pulling or using a weeder tool. Crabgrass can regrow if any of the roots are left in the soil, so make sure to get as much of the root as you can.
Use Baking Soda Vinegar Or Corn Gluten
If you are wondering how to kill crabgrass all-natural way, applying home-made killers such as baking soda, vinegar, and corn gluten is a great idea. Its the stuff all of us generally have in our homes, so it will also save you a trip to the store and save you some money.
Phytotoxin content of baking soda will do harm to any pant it comes in contact with. As with touring hot water, its best used in isolated areas and single patches of crabgrass.
Simply spray some water over crabgrass or any other plant you need to be destroyed for that matter and sprinkle baking soda powder over it. In the course of a few days, you will see the results and then uproot the dead plants, rake the surface and plant new grass.
Using vinegar is a great method of dealing with crabgrass since, while it has the same effect on plants as the
Roundup, it does no damage to the soil, and after you apply it ground is ready for reseeding. The best way to use it is by combining it with salt and liquid dish soap.
Vinegar and salt will dry the crabgrass out and soap will allow the plant to soak up the solution. Pour 1 gallon of vinegar, 1 cup of salt, and 1 tbsp of soap in a bowl or a bucket and mix it well. Spray the weed once a week, although youll generally notice the effect within a day or two.
One of the best organic preventers of crabgrass growth is corn gluten. It obstructs the development of weed roots.

Can Crab Grass Killer Be Applied To New Grass That Was Seeded Last Fall
Garden Counselor ANSWER:
Grass that was seeded last fall should be well enough established now to withstand crab grass killer. If the grass has grown well, and looks healthy, it should be fine to go ahead.
Expect that the grass will show yellowing after application of this herbicide. This is quite typical of many chemicals on lawns. It should grow out of that after 1-2 mowings.
It is important that you do not mix crab grass killer any stronger than recommended on the label. It is better to have to do a repeat application than hope for a better weed kill ratio by using a stronger dose. A new lawn will be more susceptible to a higher concentration of active ingredient than will the weeds.
Also a critical concern is that you do not use any weed killing product when temperatures are too high, above 85 degrees. The heat pulls more moisture out of the grass blades, which means the chemical being absorbed sits at a higher percentage than if the grass was well hydrated.
As some of the articles state, you want to have watered the grass well prior to spraying . That way the lawn can handle the stress of being sprayed and left unwatered for the required time.
I am assuming you have a typical bladed grass type, like fescue, rye or bluegrass. Crab grass killer will kill St. Augustine, zoyzia and some other grasses. So be sure to read the label thoroughly for any other cautions.

When To Apply Crabgrass Preventer
Knowing when to put down crabgrass preventer is just as critical as what type of ingredients to use. Most recommend adding pre-emergents in either late winter or early spring and repeating the process the next year.
Another option, however, is to pay close attention to the weather patterns in your area. Because all parts of the United States come into their seasons on different schedules, the best way to identify optimal prevention times is by noting soil temperatures.
Once temperatures reach 55, add the pre-emergents to the soil. If you notice shrubs or trees budding, this is also a good indication that weather conditions are ideal for adding the component.
Hopefully, these lawn care tips for keeping crabgrass at bay provided you with all the extra help you require. While some lawns may require additional maintenance and treatments in severe cases, consistency is the greatest asset to any plan. Knowing when to apply crabgrass preventer is equally as important when it comes to stopping new growth.

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.

Options To Treat Crabgrass Without Harming New Grass Seed
Note: the information below only relates to the crabgrass preventer that we use on our customers lawns at Green Giant. Other materials may or may not give the same results.
The options are listed in the order we consider the most preferred to the least desirable.
- The fertilizer & crabgrass preventer get applied first
- Allow the materials time to settle into the soil for at least a few days
- Then perform the aeration and over-seeding
This process has been studied extensively and the results consistently show that the crabgrass preventer has very little, if any, adverse affect on the good grass seed.
- First, aerate and over-seed the lawn early in the spring, as early as possible
- Wait until the majority of the grass sprouts are at least 1-2 inches tall
- Apply the crabgrass preventer
This process should eliminate any risk of the crabgrass preventer harming the grass seed . The down side can be that the process starts later in the season if the aeration & seeding is delayed. This is ok but it might mean more watering as we get into the summer.
- Aerate & Over-Seed the lawn
- Treat crabgrass preventer with a post-emergent spray
Although crabgrass can be controlled with a post emergent material after the plant is growing, it is less effective , more expensive and can damage surrounding good grass. Crabgrass preventer is considered to be the most critical component for effective crabgrass control. If possible, we recommend going with option 1 or 2.
Vinegar As Natural Crabgrass Killer
One of the most popular homemade weed killers for DIYers everywhere incorporates ingredients like vinegar, dish soap, and table salt. Both the vinegar and salt dry out the weed, while the soap breaks up the surface tension to allow the solution to soak into the plant. This recipe works best on a bright sunny day to speed up the drying out process.
- 1 gallon of white vinegar
- 1 cup of table salt
- 1 tbsp of liquid dish soap
When preparing this DIY natural weed killer, mix the contents in a large bucket but keep a spray bottle nearby for more accessible application to specific weeds.
For the best way to get rid of crabgrass, liberally spray the weed, soaking all the blades of grass with the solution and allowing it to sink deeply into the roots. Use this method once a week as necessary, though you will generally notice results within two days of spraying. Pull up whats left of the weed and add some grass seed to the area to discourage further crabgrass growth.
