How to Control Crabgrass Naturally with Mulch

For the longest time, mulching is a good friend among gardeners looking to control crabgrass and other annoying weeds and grasses in their garden or lawn effectively.

Mulch is effective in keeping these weeds from getting warmth and light that they need to grow and survive. Here are some easy steps to follow to use mulch in controlling crabgrass naturally:

Put down up to three layers of mulch to the soil in order to deprive weeds form warm soil and light. You can keep the crabgrass from sprouting with mulch because they’re able to keep the seeds from germinating in the first place. Mulch can block the access of weeds to the sunlight, depriving them of energy to help them get through the mulch.

Think about the mulch to add to the soil. Small stones and pebbles can be used to mulch the soil. If you do, you don’t need to alter or break down the soil.

In some cases, straw can be used in vegetable gardens; however, it is more likely than not to have many weed seeds. On the other hand, some gardeners also use grass clippings.

There are also those that use bark mulch, which can give the lawn or garden a nice finished look while controlling the weeds. This method can also help in amending the soil because it can break down over time.

Pro Tips:

  • If you’re mulching around the garden, you must wait until the flowers have pushed through if you have a perennial bed. You can lay down up to three layers of mulch around it.
  • You should plant annual flowers first before mulching the surrounding area.
  • Adding mulch around trees, roses or shrubs, you must avoid piling the mulch against the stem and trunk bases. If using mulch like a wood product breaking down over time, you should replenish the material yearly to maintain the proper layer.
  • Replenish or renew the mulch color. Just like other garden materials, mulch can fade and break down. You can renew the color of the mulch by refreshing it. For one, you can spray it with a color renewal product. Be able to follow directions properly so that you can get the best results out of it.

Choose a product that is safe for use around pets, plants, and people. To prevent staining of surfaces, you must avoid patios, driveways and other surfaces. Without all much work, you can make your plant beds correctly mulched.

Controlling weed using mulch like wood materials or another we have previously discussed, you can certainly get rid of weed in your lawn or garden. It is also easy to use and can be done annually depending on the material used or how fast it is broken down.

Nevertheless, mulching is one of the older and more effective methods of controlling weed in your garden or lawn. Be able to choose which material to use and ways to apply it. Certainly, adding mulch is a natural way of preventing and controlling weeds and grasses from growing back.

Many of these home remedies are just right there in the kitchen. For example, vinegar has long been used to eliminate crabgrass. It can be used alone or with other natural ingredients.

Vinegar is a cheap and effective solution. However, you should remember not to dilute it if you have chosen this remedy. In addition, be sure that you apply it on a sunny day. Or else, the rain will just wash it away.

In terms of concentration, it will be best to use a five percent solution for targeting small and young weeds.

On the other hand, you must go for one with 9% concentration if using for pickling. It will also be the better choice if you’re trying to kill stubborn and mature weeds.


If you’re looking for crabgrass preventer, you can also use salt. It works effectively to target and kill crabgrass because it can stop the growth and kill the weed immediately.

However, remember that this remedy can also be useful if you don’t want to plant growing on a specific area like the driveway or the sidewalk.

You might also opt for this solution if you want around the house, patio blocks and beneath decks to be free from unwanted grass and weed.

Remember that salt can also damage surrounding soil. To use it, you should mix a part of it to two equal parts of water. On the other hand, you can apply salt in itself directly onto the weeds.

Alternatively, you can also mix one and one-fourth cup of it with a gallon of vinegar, and then spray it in places where the crabgrass grows.

Rubbing alcohol

You can also use it to kill crabgrass because it leads to the loss of moisture from its cell. To use it, just spray it on the weeds directly. Also, you can dab it on using a cotton ball.

For the best results, you might have to reapply it for deep-rooted crabgrass.


Just like vinegar, lemon is another effective home remedy to kill crabgrass. To use it, you can just use lemon juice on its own, or add it into one-half cup of lemon juice with a quart of vinegar.

Dishwashing liquid

It is another remedy to use against crabgrass that you might want to check out if you would like to control this grass from growing and spreading into the garden.

You can use it alone or with vinegar to make it more effective. To start, you can fill a spray bottle with vinegar before adding dishwashing liquid. Start spraying this solution at noon or the hottest times of the day.

Alternatively, you can mix a part of the dishwashing liquid with 10 parts of water before soaking this grass with the mix.

Other Important Factors to Consider

What is Crabgrass

You’re probably wondering if what you’re seeing in the lawn is the annoying crabgrass, which in its name you could safely say it has many legs or stems. This grass is often characterized by being low to the soil or ground.

You would also notice it’s invasive that it has a procumbent growth habit. It is one of the reasons the grass is successful in becoming a real annoyance for homeowners.

Below is a short video of what crabgrass actually is:

This grass can pop up through a small crack in the sidewalk. It grows almost anywhere, making it hard to stop. You can also see it growing along a driveway.

And most of the time, the crabgrass can elude the blade of the mower, so there are not many options that can really break into it.

Did you know that it could also keep up well with foot traffic? And even stepped on, they can hold still survive. Can you just imagine how hard to stop this grass is? It has tough seeds, too, so it can reproduce so quickly.

For this reason, lawn owners think of using the strongest weed killer to eliminate crabgrass. It can really survive even the toughest conditions that you could think of.

What does Crabgrass Look Like

Before using a weed killer, you must know how your enemy looks like. But as good in survival, the grass is also known for its ability to have different claims of assortment on its appearance for many people.

There is no question that this grass has many faces that it carries. One of its major secrets is its ability to adapt to different conditions and circumstances. You have probably seen crabgrass looking differently from one place to another.

Also, there are many who claimed that its growth habit might have changed dramatically. It can sometimes change in color, too which can vary based on how well it is fertilized and on its variety.

For example, those that have grown in places where there is enough water will be healthy and look like any grass you could imagine there is. But as they mature, they will look different from anything in your lawn.

They develop those larger, thick mats, which are obviously not a part of the lawn.

Their leaf blades are wider versus other lawn grasses have. Also, the blade is with a fold line down to its center.

Remember that these blades are growing from separate locations on the grass’ stem, not from one single middle point. These blades are not too long or too short.

Once the crabgrass has moved into the lawn, this grass tends to grow up faster than your lawn grass.

But by maintaining your lawn and killing crabgrass with a natural weed killer, you can limit the growth pattern of this grass.

However, if you will leave it unattended and uncut, it can grow upright, forming a dense clump out of which it’ll send out tall seed stalks and long leaf blades.

Types of Crabgrass

You must know that there are certain types of Digitaria or crabgrass, the hairy and the smooth one. However, you are likelier to find the hairy one than the former in your lawn.

Digitaria sanguinalis or the hairy crabgrass is what you will normally find in your lawn. If you would look at it closely, you’re going to find it has hair all over its body.

However, it doesn’t mean that the hairless type or the smooth crabgrass does not have hairs because it has some. You will find these on the auricles of the plant.

The smooth crabgrass has a bent stem and a five-inch leaf. At is maturity, its leaf can measure up to five inches long with its blades tapering to a certain point. Its stems are bending at its nodes, while its stems are turning reddish in color. This type is also called small crabgrass because it is usually smaller than the hairy variety.

Why is Crabgrass Bad

There is no doubt that the crabgrass is bad after reading all these about it. For one, it is very stubborn, which makes it hard to stop when it starts invading your lawn.

It is also aggressive and invasive. In fact, it can spend a season to spread tons of weed seeds, which are waiting for the next spring. They are just lying in wait in your lawn until they’re ready to make us crazy again.

It thrives in the un-kept and stressed out garden or lawn areas like the sun-scorched turf. When unattended, it can invade and take over your lawn.

You can also imagine how hard that it so eradicate them once they have spread because they can also spread thousands of seeds. If you wouldn’t be able to control the annoying grass, you might have a problem eliminating them. For this reason, go over our recommended ways on how to get rid of crabgrass without chemicals.
