Some homeowners have no issue with dandelions invading their lawns. After all, dandelions are a delight to kids. Their yellow flowers are stunning and attractive. Blowing their seeds makes for an enjoyable experience for kids. 

However, the presence of dandelions might spell doom for your sod. Not only will they push out other plants around them, but they will also consume nutrients and water meant for the grass, leaving the surrounding patches of grass malnourished.

If you value your lawn and its long-term health beauty, you should kill all dandelions that sprout in your yard. 

When left unchecked, dandelions might colonize your entire lawn. Their fluffy and floating seeds reach far and wide, making dandelion control daunting after the first few seeds disperse. As such, the earlier you deal with this weed, the better it is for your lawn.

Today, we will explore the best dandelion killer for you to kill this turf grass weed once and for all.

While each of the listed herbicide has its strength and weaknesses, they are all effective at getting rid of dandelions.

Other FAQs About Getting Rid of Dandelions

How do you kill dandelions but not grass?

The best way to kill dandelions is to use a selective broadleaf herbicide. This type of herbicide is formulated to kill broadleaf weeds, including dandelions, without affecting grass.

Alternatively, you can use non-selective herbicides to spot-kill dandelions. Using a non-selective weed killer is a risky option, as the grass around the spot will be affected.

It worth noting that to kill dandelions effectively, you should apply your chosen selective and non-selective herbicide before they start to flower. After flowering, they are difficult to kill, even when you use non-selective herbicides.

How do I permanently get rid of dandelions?

The most effective means of getting rid of dandelions for good is to target their roots.

Regardless of the treatment you choose, you should ensure you target and kill the entire root system. Whether you decide to uproot the plant or apply herbicides, ensure you target the roots as well.

Should you pull dandelions?

Uprooting the plant is one way of getting rid of dandelions. If you notice a handful of dandelions in your lawn, you can opt to uproot the plants to remove them from your yard. 

However, when pulling a dandelion, you should ensure you remove every inch of its roots. Their brittle taproots are easy to break, which increases the risk of dandelion regrowth. Roots as small as 1 inch is sufficient to generate a new plant. To prevent the regrowth of dandelions, ensure you uproot the weed and its entire root system.

To increase the odds of successful uprooting, you can use a specialized tool designed to aid pulling dandelions. However, all things considered, the best and easiest solution to a dandelion infestation is to use the best dandelion killer listed above.

Is there a natural or organic way to kill dandelions that works?

If you are an ardent proponent of organic gardening, you’d be pleased to note that organic and natural means of removing dandelions (aside from pulling the plant) are available.

The only caveat is most organic dandelion killers are best used for spot treatment. One of the most effective organic dandelion killers is pure white vinegar. Spray the vinegar until it covers the entire dandelion plant to kill the weed. 

You might need to repeat the spray multiple times until the plant turns brown.

You can also use rubbing alcohol to kill the plant. Spray the weed plant with rubbing alcohol thoroughly. Finally, you can use boiling water to kill the plant. After the plant wilts completely, pull it from the ground.

Final Throughts

Do not allow dandelions to wreak havoc on your lawn when you have the choice of killing the weed.

There are plenty of options when it comes to the best dandelion killers. Use one of the herbicides we have listed above to get rid of dandelions permanently.
