Why Do I Have Lawn Weed?

After getting to know the infamous types of Lawn weeds, you want to know what brought them to your yard, and what created a suitable environment for their growth in the first place.

1. Compacted Soil:

Compacted soil suffocates the grassroots, depriving the roots of the water, fertilizers, air, and nutrients they need to grow.

This can mainly be caused by excessive traffic or insufficient soil care.

2. Poor Watering:

Having a poor irrigation system for your lawn can sometimes lead to poor watering.

You’ll need to water your grass enough, so that even when the weeds aim to “steal” the moisture in the soil of your grass, watering enough can get the needed water for the grass, despite the weed’s efforts.

3. Poor Grass Growth:

When your grass suffers from any kind of bad maintenance, it’ll grow poorly in some sections. The ideal situation for the weeds is to find poorly cut grass to invade.

On the contrary, well-maintained grass that covers the whole lawn won’t be susceptible to such invasion.

How to Get Rid of a Lawn Full of Weeds

Keep in mind when you want to get rid of lawn that is full of weeds, that you need to get rid of them as soon as they first show face.

The more you wait after noticing the growth of weeds, the more time you’ll give them to grow further and longer and more dangerously.

Here are some conventional & unconventional methods on How to Get Rid of a Lawn Full of Weeds:

1. Remove Weeds Using Your Hands

Put on your gloves, it’s time to harvest the weeds for good.

This is considered the most straightforward method when it comes to how to get rid of lawn full of weeds.

You’ll want to pull out the weeds by hand, put them in a larger bucket, or gather them by the side of the yard, left to dry in the sun, and die.

This method won’t be easy if you have an extra large yard invaded by weeds.

2. Invade the Invaders with Mulch

Let the weeds think they’ve invaded your yard, let them enjoy their time for a little bit, then invade their territory with mulch.

Once covered in mulch, you’ve successfully prevented the weed seeds from contacting the soil and growing further.

Moreover, the mulch says: “no sunlight for the weed seeds to grow on anymore.”

3. Homemade Herbicide’s Time

Large yard and no mulch to use now? It’s Homemade Herbicide’s Time.

It’s no complication by any means, it’s literally a large pot of hot water.

Get yourself a large pot, fill it with water, boil it, and carry it to the yard.

Now, be careful when you use the hot water, pour it over the weeds’ stems & leaves.

This shall kill the weeds effectively, with no harm to the environment whatsoever.

4. “Vinegar The Weed Killer”

Pick a vinegar that’s made with 10-20% acetic acid. Picking the standard vinegar with 5% acetic acid won’t be effective against weeds.

Pour the vinegar directly on the weeds’ leaves, and that’s the work of (Vinegar The Weed Killer).

Unconventional ways on How to Get Rid of a Lawn Full of Weeds

1. Cornmeal

Cornmeal prevents any type of seeds from germinating. This means both the weeds and the seeds you’ve already planted.

This is an unconventional way that can be used when you run out of options to counter the weeds.

Sprinkle the lawn cornmeal and leave it for a couple of days to notice the results.

2. Newspaper

Weeds are uneducated organisms that fear knowledge, show them the newspaper and they shall not grow. “Just kidding”

On a serious note, cover the weeds with loads of newspaper pages, which shall create a carpet of papers blocking both the air and the sunlight off the weeds.

Hold the newspaper down on the weeds with a load of mulch.

3. Old Curtains/Carpets

Same as newspapers, all you need to do is cover the weeds with old curtains or carpets, and they shall prevent the air and sunlight from reaching the growing weeds, causing them to die.

What to Do After Getting Rid of Lawn Full of Weeds?

Advice on How to Protect Your Lawn After Removing Weeds

1. Attend to Weeds ASAP

The main advice to give on removing weeds is to attack the weeds as early as you can, to prevent further damage, according to Lawn Advisors testing.

I’d advise you to start in early spring, you can monitor the soil temperature, making it stay around 50-55 degrees Fahrenheit, which significantly decreases the growth of the weeds.

They always prey on 50 degrees or less, keep them away from that degree.

2. Feed Grass Well

The better you feed your grass, the better the grass’ growth will be.

Healthy, dense, and tall grass is always an impossible task for weeds to thrive on.

Other advice:

  1. Mow the Grass More Often.
  2. Perfect the Lawn Aeration.
  3. Keep the Lawn Well-Watered.
  4. Fertilize the Lawn Properly.
  5. Plant New Seeds Whenever Necessary.
