What is Dandelion?

Dandelions are a broadleaf perennial. They can grow in any soil. They thrive well in full sunlight.

In the early spring months, new sprouts will show up from the taproot. The taproot can be 3 feet deep in the soil.

They produce yellow flowers that will turn into white puffballs. These puffballs contain seeds that spread out helped by the wind.

The plant seems like it has been disappearing in the fall. The taproot still survives in the soil. This taproot will start the life cycle again in the spring.


Why kill Dandelions?

Dandelions belong to the subset of weeds called broadleaf perennials. Broadleaf perennials are a challenge to remove.

When the Dandelion plant has fully mature, seeing its 10-inch-long taproot, the Dandelion will come back year after year. They will spread their spawn across the lawn in perpetuity.

The root is the key to total elimination. If you want to kill a Dandelion, you must kill or remove the taproot. If you don’t, the unwanted sprout will come back again.


What is the best Dandelion killer?

If you have Dandelions growing in your St. Augustine, centipede, or Zoysia grass lawn, you can use a triple action herbicide that can control weeds of your lawn at the same time.

Dandelions are broadleaf weed. How to get rid of dandelions?

You need to buy a herbicide specially formulated to kill off broadleaf weeds. Buy a broadleaf weed killer to kill Dandelion.

Mowing Dandelions can not kill them. Dandelions must kill at the root, not the stem.

You do not hand-pull Dandelions because, eventually, they will grow again. As mentioned before, to fully and completely kill Dandelions, you have to eliminate the taproot, which can be 2 to 3 feet (91.44 cm) deep.

If hand pulling Dandelions is a hard task for you, you can choose from the below list of herbicides to get rid of Dandelions.

Types of Dandelion killer

Selective Herbicide

This type of herbicide kills Dandelions but does not harm your other plants and keeps them remain healthy. A selective herbicide is a substance that will get rid of Dandelions without damaging or harming the other plants in your garden or yard that are wanted.

Non-Selective Herbicide

If you notice Dandelions popping up through the cracks in your patches or sidewalk in your driveway, you should choose a non-selective herbicide that will kill all or every plant it touches, including Dandelions.


How to get rid of dandelions?

You can pull a Dandelion by hand if you want to remove it. If your pulling efforts do not seem to reduce the problem, use a broadleaf herbicide as a last resort.

But you can still use the Dandelion removal tool to get rid of Dandelions. It worth the effort but you must remove the roots completely.

These Dandelion removal tools are including a claw garden weeder, bend remover tool, and weed extractor. They are effective Danbdelion removal tools.

Before applying herbicide to kill Dandelions, it is best to check the weather and wait for a sunny and dry day. Get a broadleaf herbicide ready.

You must wear your gardening gloves, goggles, and protective clothing. Prepare a pump sprayer and add the chemical. Mix it with water and follow the instruction label on how to mix.

Using the pump sprayer, apply the herbicide specifically to the Dandelions plant in your garden. Let it dry out. Wait and notice in several days that the Dandelions’ foliage turns brown and dies.

When you see that they are dead, pull out or rake up the remains of the weeds. Wait three days after the application, and after that, you can reseed with grass seed.

You can do this practice in 1 hour, with only spending $20 on herbicide for application.


How to prevent Dandelions?

How to prevent Dandelions? Keep lawn healthy is the best way for Dandelion prevention from growing. Do not rescue the grass lawn from weeds.

You have to manage your lawn properly actively. If your lawn is healthy, it can compete effectively against the Dandelions. This will remove any effort of Dandelion removal systematically.

You can do the leaving grass clippings on your lawn — the practice act as a mulch to block and stop weed seeds from germinating.

Mow lawn grass at the height of 2 to 3 inches (7.62 cm). This mowing practice will let the grass protect itself by reducing weeds of the light they need. It is a good method of Dandelion prevention.

Do not allow bare spots to be uncovered for a long time. It will stimulate the invitation of opportunistic weeds. When the fall months come, fill in bare spots by overseeding the lawn.


How to get rid of dandelions?

How to get rid of dandelions? You can prevent Dandelions from taking over your lawn and kill them using natural organic or chemical controls. Mostly, killing Dandelions by applying chemical controls is efficient and effective.

Natural Dandelion killer or organic treatment is labor-intensive but more eco-friendly or pet-friendly.

Dandelions will kill turfgrass that is thin and at a stress level. Dandelion prevention from taking over is by maintaining a dense and healthy lawn.

This condition will make it hard for weeds to grow. The ideal time to kill dandelions is before they seed. Dandelions spread by seed.

The challenge of killing dandelions and preventing their return

Dandelions have a long taproot that allows them to live in the winter and grow in the spring. A small piece of the taproot has the ability to form a new plant.

New Dandelion plants spread and sprout from seed. It blooms bright yellow flowers and will form white puffballs full of seeds. These seeds will spread, taking advantage of the wind.

One flower alone can produce many seeds that will multiply around the lawn. Then the winds will carry them and spread them over many distances.

After reaching one spot, the seed will germinate throughout the growing season.

This is a real challenge for Dandelion prevention.


When to apply herbicide on Dandelions?

During the early fall, nutrients in the Dandelions plant are transferred from the leaves to the roots. This is the best time to apply herbicide.

This is because chemicals or organic control applied during this time will be absorbed by the leaves, and the chemical will be transferred onto the roots. The chemical will follow the same direction as the nutrients.

So, late spring and early fall is the best time to use broadleaf herbicides to kill dandelions.

To ensure adequate herbicide absorption, stop mowing the lawn 2 or 3 days prior to application. After the application, wait for 2 or 3 days to pass before mowing.

This allows the herbicide to be transferred to the plant’s roots. To prevent the broadleaf herbicide from being washed off the plant’s leave, the application should not get rainfall within 24 hours. Stop watering the lawns within 24 hours after the application.


How these herbicide work

1. Post-emergence herbicides

These post-emergence herbicides do their job on living weeds. They work when the weeds sprouted and are visible.

Organic post-emergence herbicide sometimes only works on a very young plant. But the post-emergence herbicide chemical sprays can control much older weeds. The organic product needs to repeat spraying several times and may fail. That could be disastrous.

Post-emergence products can stay in the soil longer than necessary. These can prevent the growth of other living plants. The herbicide will very slowly break down.


2. Pre-plant herbicides

These products are rarely used. They are commonly used in an agricultural setting. The pre-plant herbicide must be put to practical use in a set time period prior to planting any desired plants or seeds. In most cases, the time period is between fourteen to forty-five days.

Once the pre-planting herbicidal is in practical use, the herbicide will eliminate the weeds. The application can prevent any seeds from sprouting. The application may cause harm to any transplants as well.

It is not recommended to use pre-planting herbicides for home gardening purposes. It is one of the excellent methods for Dandelion prevention.

They are suitable for a large-scale field setting. It is where the field can be sprayed, plowed quickly, and let be alone for a set period of time.


3. Pre-emergence herbicides

This pre-emergence herbicide has a job to prevent, block, and stop seeds from germinating. Other jobs are sending up sprouts and seedling weeds.

If you see any existing weeds, they will not control them. Unfortunately, different areas have different weeds.

Pre-emergence herbicide leave residue in the soil after application. That would be bad for most home gardens.

Please read the labels carefully. Select the one for dandelion. There are pre-emergent sprays and granules out there for dandelions. It is excellent for Dandelion prevention.


Will herbicide kill Dandelions?

The answer is yes. Herbicide works and kills dandelions. Some formulations only work on Dandelions and some kill everything around the Dandelions also.

Other herbicide works faster than others. Kill your dandelions while they are yellow.

Kill them before they can form their seed. Do not the seed spread before you kill them.

A herbicide is also a good method for dandelion prevention.
