How to Remove Purple Flowering Weeds in 3 Steps

You first need to identify the specific purple weeds to decide the intervention that best works for the situation.

After you eradicate them, you must continue your method to ensure they won’t return.

Here are the three steps that you can follow:

Step 1: Identify Weeds With Purple Flowers

To efficiently remove weeds with purple flowers, you must know the types of weeds you are trying to eradicate.

There are purple flower weeds that you can remove by hand pulling, but you have to be cautious about other kinds because they might be poisonous or you might damage your lawn.

Inspect your lawn and see if the purple flowers are the ones you’ve planted on purpose.

Otherwise, if you find flowers growing unintentionally, you can infer they are weeds. Discard them immediately so they don’t block nutrients for your other plants.

You recognize them through their physical attributes, such as stem height, leaf size, and shape.

Plenty of weeds are related to the mint family, so when you pulverize them, they produce a sharp odor, making it easy for you to recognize.

Step 2: Decide on the Treatment

When you already determine the weeds with purple flowers, you can proceed to the next step: Choose the treatment to use.

Various plant species react to particular types of treatment. It would help if you learned what and how to use the treatment for good outcomes.

You can select from the following methods:

1: Herbicides

You can easily get rid of weeds using chemical weed killers.

The more you need herbicides if they infest the entire lawn and surpass your plants.

However, you must remember that chemicals can also harm your desirable and cultivated plants and the lawn, so double-check the label on your weed killer.

If it contains glyphosate, it will eliminate most of your plants. Limit your application only to the weeds with purple flowers you want to eliminate.

You may not consider spraying herbicides since they can damage your plants in the area.

2: Pulling

If the purple flowering weeds do not occupy your entire lawn and have shallow roots, you can manually pull them by hand or use a weed-pulling tool.

You can even put water around the weeds to have moist soil, then grab the plant at its base so you can take as much of the root and the entire plant to prevent it from growing back.

3: Mulching

Perhaps, you may hear mulching as a widely-practiced gardening technique. This is the process of masking the soil with organic materials.

It will maintain moisture and boost the condition of the soil.

The layers will protect and help in fending off the weeds with purple flowers.

You can put a thick layer of mulches to choke out the weeds.

There are two types of mulching that you can do to have a weed-free lawn:


Organic mulches are usually used to increase nutrients and enhance the soil’s fertility because they can decompose.

You can use bark, wood chips, leaves, pine needles, and banana or coconut leaves.

You can shop at Amazon for Juniper Bark Chips.

The mulches decay at varying rates, as it will depend on factors such as climate and microorganisms in the soil.


Inorganic mulches are low maintenance, as restocking is not necessary. They won’t decay and add nutrients to the soil.

You can use inorganic mulches such as stones, lava rock, and pulverized rubber.

4: Fire

You can use a small propane torch to demolish unwanted purple flowering weeds.

There are weed torches that you can purchase at Amazon.

BE CAUTIOUS and CONTROL the flame. This technique works well in zones where you cannot apply mulching, such as stone pathways.

5: Garden Health

A bit of common weeds does not indicate that your garden is unhealthy. You can maintain your lawn and garden health by:

  • Let your lawn grow thick using fertilizers, especially in the right season, to achieve its peak growth.
  • Water your grass and garden beds and place the plants close together. So, the healthy plants will absorb the nutrients and leave a slight amount for any weeds.
  • Tightly packing the plants will make them too covered for the weeds with purple flowers to prosper.

Step 3: Repeat

After you ensure that your lawn is free from common weeds such as Creeping Charlie, Purple Dead nettle, Wild Violet, and other weeds, you can sit back and relax for too long.

Consistently inspect your yard to ensure it’s healthy, and you may carry on with your method of weed control during a particular season.

Have a routine so you can stop the weeds from infesting your lawn.


Here is some additional information that may come in handy when you see purple weed in the grass.


Flowering weeds can be pretty to look at with their delicate colors and forms.

But, as you may know, they can be useful or a nuisance.

A piece of advice, know what you want to do with them early on, as they may blanket your lawn and risk your plants.
