Today, we offer you what we consider to be the best dandelion killer reviews on the web, as well as several tips and product comparisons to help you make the right choice.

How do I Get Rid of Dandelions in my Lawn?

Dandelions can be a huge nightmare for your lawn or garden as they are difficult to remove and they propagate easily. Dandelions are also known as broadleaf weeds. The best method to get rid of dandelions permanently is to kill them by the root; this can be accomplished in several ways including the use of herbicides, either commercial or organic, or by removing them manually from the root. Some people have reported getting the job done by spraying their lawn with vinegar, but this isn’t always effective.

Choosing the Best Dandelion Killer for Your Needs

If you are looking for ways to get rid of dandelions, a dandelion herbicide is a great method to do so. Killing dandelions in a lawn without killing the grass with herbicides can be very easy if you just spray the dandelions. This certainly beats having to pull them out manually, which is very labor-intensive.

There are also special herbicides that are designed to control dandelions before and after their emergence. Pre-emergent herbicides will help control dandelions and can be used in late winter for maximum effectiveness, whereas post-emergent herbicides are typically used in fall. You should choose a dandelion killer based on your particular needs.

​Selective and Non-Selective Herbicides

When choosing the best dandelion killer, there are several types to consider. Most commercial dandelion killers fall into two categories: selective and non-selective.

In short, selective dandelion killers are formulated to target dandelions only. This is an excellent choice if you want to kill the dandelions without killing the grass or other plants in your lawn. The other type of herbicide, non-selective, is formulated to kill all types of dandelions, weeds, and plants.

This is a great choice if you have dandelions or weeds coming through cement cracks or on walkways, but it should not be used for the lawn as it will kill the grass and other vegetation.

Although commercial herbicides and dandelion killers are great for killing dandelions and weeds, some people may opt for more environmentally friendly options to kill dandelions. You can kill dandelions by pulling them, although this is very tedious, or by using an organic dandelion killer.

Killing Dandelions by Pulling Them

Another way to kill dandelions without using an herbicide is to pull them.  But be warned: dandelions can be very hard to kill by pulling. Their seeds are above ground and are easily propagated. They also plant their taproot about 10 inches long, making it difficult to pull. The root fractures easily, so even if you pull it, you may not get the entire root, allowing the dandelion to grow right back. It’s also worth noting that dandelion roots are very good for your health!

Nonetheless, if you do try to pull them, first water the lawn as wet soil makes it easier to extract. Then, make an incision parallel to the taproot, using a dandelion removal tool or a dandelion digger, which is a tool specifically designed for removing dandelions.

Your next step is to loosen the tap root and gently pull on the dandelion taproot. If the taproot is very loose, remove the dandelion from the soil; otherwise, repeat the steps and continue to tug at the dandelion leaves until you can remove the entire dandelion.

Organic Herbicides

Vinegar is often used to kill dandelions as the acetic acid can be used to kill dandelions and is an organic alternative to commercial herbicides. Although vinegar is used for culinary purposes, you can boil down the vinegar to yield a stronger percentage of acetic acid.

The stronger the acetic acid, the better it will be as an organic herbicide. Many people opt for killing dandelions with vinegar because it is a more natural way to control weeds that is also better for the environment.

When is the Best Time to Spray Dandelions?

The best way to get rid of dandelions permanently is to know the best time to do it. Early fall is the best time to spray dandelions with herbicides, more specifically with post-emergent herbicides. Since they are broadleaf, herbaceous perennials, their leaves die in winter time but their roots remain alive and intact. In fall, the leaves transfer nutrients to their roots, so you should spray them while this occurs.

Post-emergent herbicides sprayed on the leaves will transfer down to the taproot.  If you are wondering if you should spray dandelions before or after mowing, it really depends of the size of the dandelion leaves, as they are the ones that absorb the herbicide.

You should spray dandelions before mowing the lawn as the bigger the surface area of the dandelion leaves will allow the herbicide to be transferred.  Although you can spray dandelions before and after mowing, you should ensure that there are enough leaves for this to be effective. You should also wait at a few days before mowing in order to allow the proper time for the herbicide to be transferred to the roots.

Overall, there are several effective methods to kill dandelions. You should choose a method based on the needs of your lawn or garden and your own capabilities, both physical and economical.
