If you are a lawn keeper and love to maintain your lawn like a pro, you have to fight many antagonists and vile creatures that will not only destroy the charm and gorgeous look but will also be a catastrophe to the plants.

One of such vile weeds is Crabgrass. 

crabgrassThe crabgrass (Digitaria) is a vile annual weed. It penetrates the turf grass lawn and hence is despised greatly by the horticulturists. It spreads away with weed seed and grows in clusters. It is called crabgrass as its legs emit out like the legs of a crab. It spreads in bulk if not taken care of in the initial stages. It germinates in the warm season. It is a coarse, unattractive and unwelcoming weed that grows annually in the summers but its effects do not end by the end of the season. Its life span is only a year but its consequences are long lasting. 

The first tip in this regard is totally organic with zero percent involvement of the chemicals. 

How to Kill Crabgrass Organically?

When you opt to do a lawn treatment without letting a chance to the chemicals, it is an organic method to snip the weed. It starts with nipping the weed and sowing the grass seed.

Here are the steps.

01. Bathe the Soil with water

Water the targeted area with an irrigator or garden hosepipe.

Give time to water to seep into the soil properly. One and a half hour will be enough. then wait about 30 minutes to allow the water to soak in.

02. Pull Out the Crabgrass

Manual PullingRemove the newly sprouted fresh crabgrass plants with the help of propel or with a weeding tool. Pull out the crabgrass along with its root. Only stem cutting will not do. It could be tiresome if your problem area is a bigger one. Move the plant steadily upward so that the stem does not get broken. It will be easy as the soil is dampened enough to let go of the roots. 

03. Add organic Compost

After the process of pulling out the weed, compost the area with something organic. Thoroughly and uniformly combining the compost is necessary. 

04. Topseed with Turf Grass Seed

Spread the area with grass seeds. Then spread a grass mulch over the area to nourish the soil and retain the moisture and healthy nutrients. It will also stop birds digging out the seeds.

05. Keep the Soil Moist

Irrigate the soil various times a day. Such a practice will dampen the soil considerably and will be very feasible for grass seedlings to sprout. 

06. Switch to Deep Watering

07. Mow the saplings

To keep up your new area of grass, mow it high. It refers to mowing the lawn in such a way that the grass left behind is no more than 3 inches tall. It will protect its own turf. This process will stop the sunlight reaching crab grass and kill them eventually.

08. Hoe as Needed

The pulling out of crab grass is not confined to one day only. It should be done over and over again all throughout the year. Pull out any crabgrass that sprouts out. This will leave your patch crab free the upcoming spring.

We can pull out the weed in early spring manually or with the help of a machine. Reseed the empty patches and provide basic required nutrients.  This is an eco-friendly way to eradicate the weed.

If the crab grass is persistent and is spreading in influx, you need to worry about it a lot. This post emergent case needs a proper chemical treatment. It is to be done as early as possible as tender grass crab is easy to destroy. So act sharp and smart!  

Tips to deal with the crabgrass:

Given are the most prominent tips to deal with the vicious crabgrass.

Pre-emergent Treatments

Never wait for the crab grass to be part of your lawn. You have to take some precautionary measures before this hostile and vicious weed becomes the part of your dilemmas in the yard. As precaution and prevention is better than cure, try not to let it dominate your happiness. If the timing of the action is accurate the success is yours. So to nip the evil in the bud, the horticulturists have to be well equipped with the “war heads”. It starts growing in spring when the mercury touches the 55 degrees of the Fahrenheit scale. We need to have a Pre-budding strategy. To kill the bird before it’s hatched is the best stratagem ever. There are many herbicides that tend to kill the crab grass quite efficiently before its emergence.   

The preventers for the crabgrass work before it peeps out of the soil. So keep an eye on the temperature of your soil for timely action. Apply any chemical, preventer, weed killer, or any domestic trick before the attack of the crabgrass.  

Preventive (Pre-emergent) Treatments

HerbicidesThe herbicides can be considered as pre-emergent chemicals that can help vanishing the crab grass before it even sprouts. They have dual benefits. To kill two birds with one stone, the chemicals not only kill the crabgrass it also stops and precludes the weed seed from germinating ever again.

Pre-emergent works by obstructing seed germination. Furthermore, it also stops the root development of the weed. Which is why even if the weed survives the blow it can never become a strong plant nor can do any damage to the soil or neighboring plants. Pennington Ultra Green Crabgrass Preventer plus Fertilizer III 30-0-4 is a superior crabgrass and broadleaf weed preventer. It works for up to five months. The plus point of this preventer is being a fertilizer it also nourishes the yard’s grasses.  

According to a recent research, the mentioned below chemicals are deemed to be effective means of pre-emergent control:

  • Benefin (Lebanon Balan 2.5G)
  • Benefin and trifluralin (Team)
  • Bensulide (Bensumec)
  • Bensulide + oxadiazon (Goosegrass/Crabgrass Control)
  • Dithiopyr (Dimension)
  • Oxadiazon (Ronstar)
  • Pendimethalin (Pre-M, Pendulum, Halts)
  • Prodiamine (Barricade)
  • Siduron (Tupersan) 

Attention: Always monitor and obey the directions on the label or manual before using a specific preventer. Generally two months gap is recommended or two mowing spaces is given between using a preventer for the second time again. 

Post emergent treatments

Understanding the crabgrass cycle

The real thing in this regard is understanding the crabgrass emergence and its cycle. The crab grass ends with the end of season but not its aftermath. A single crab grass produces about 0.15 million seeds! These seeds are a true dilemma for the next season. They will sprout out into a new quandary in the upcoming spring and the cycle continues. The seeds that do not germinate remain active to start cataclysm the next year.

It’s no use crying over the spilt milk.

Mowing the lawn once the damage is done has no benefit. Their growth is even lower and lesser than one that is recommended to be a healthy mowing height. So mowing after it has sprouted out has no claims of victory. Thus this seed producing weed needs to be eradicated before it is hatched out.
