How To Get Rid Of Dollar Weeds In 3 Quick Steps

Dollar weed

Dollar weed is also known as a pennywort. This invasive plant species can easily thrive in warm areas or in coastal climates. They tend to grow in areas that have a lot of moisture and they can grow fast in soil that has poor drainage. They can easily take over your lawn especially if you have poor soil.

This plant is called a dollar weed because it has small, rounded leaves. Its shiny leaves also look like small coins, hence the name. In some cases, the dollarweed can be used to cover areas where grass or plants will not be able to grow. When kept properly, its leaves can actually add to the appearance of your lawn.

But when it grows uncontrollably, it can easily invade the other areas of your home, making it look like a horrible swamp or marshland. This plant spreads to different areas through its underground roots and seeds. It can be hard to eliminate. If you need help dealing with it, follow these steps carefully.

How To Get Rid Of Dollar Weeds

Step 1: Kill The Weeds On Contact

To kill the weeds right away, wear gardening gloves and pull the weed out of the ground. If there are too many dollar weed in your lawn, you can use boiling water to kill them right away. Just make sure that you will not pour boiling water on other plants as you might end up killing them as well.

If you do not want to boil large quantities of water, you can opt to use white vinegar. This substance has been used in the past to kill dollar weed. Recently, scientific studies have shed light on this claim. Researchers have shown that white vinegar with 5 – 10% acetic acid can kill the weeds in two weeks.

If you think that it is still not quick enough, then you can buy a vinegar product that has a stronger acetic acid concentration. You can buy super strong vinegars in the cleaning section or in stores that sell imported brands. Do not concentrate white vinegar through boiling since acetic acid is flammable.

Step 2: Sprinkle It With Baking Soda

If the dollarweed is still alive, use baking soda. It can be used as a low impact herbicide. This is highly recommended if the dollarweed is growing near other plants or grass. It can be used to kill the weeds but not the other plants around it. To do this, you need to wet the small, circular leaves on the weeds.

You will then have to sprinkle baking soda on each leaf. Let it stay overnight and it should die a few days later. You can also sprinkle sugar all over the plant. You can dissolve it first or you can water the area thoroughly after spreading sugar all over it. This can be used to kill the dollarweed in a matter of days.

Step 3: Re-Condition The Soil

Lawn Aerator

A great way of killing dollarweed and halting its invasion is by re-conditioning the soil. Dollar weed needs a lot of moisture from the soil in order to thrive. But by using an aerator, you can enhance the transfer of water, oxygen and nutrients within the soil. This can help strengthen the grass in your lawn.

If you do not have an aerator, you can always use more soil. Cover the areas where the dollarweed has been killed or removed with a top-dressing. This will allow your lawn to have better drainage and it can also help strengthen certain areas of the soil that has been depleted of nutrients.

Thanks for your good tips. I have small patches of dollar weed on my lawn, and wondered if cutting the petals off with a weed wacker will kill the plant. Thank you.

This absolutely does not work. Salt, vinegar, dish soap, boiling water and commercial products will kill the top of the plant right away, but is soon as these solutions hit the soil, their effectiveness dissipates completely. So you are stuck with healthy roots and the plants are back in no time flat.

The best reason not to use any of these solutions is that any over-spray will kill the plants that you are trying to save. I have killed way too many plants using these methods. So put on your gardening gloves, kneel on a gardening bench, get a spade out and run the spade slightly under the dollar weed. Take you time and allow the spade to follow the root (it can be up to four feet long). If you hear a snap, you have broken the root. Start there and keep following the root until you get to the little root ball. There is no easy way to do this. Plan to repeat this process couple of months for the rest of your life.
