Best Dandelion Killer – Latest Reviews and Buying Guide

Dandelion is a simple perennial herb that multiplies by the spread of its seeds. It generally grows in moist soils with good drainage and a lot of direct sunlight but can prevail in dry conditions as well. The dandelion can survive even in harsh conditions due to its strong taproot.

The taproot typically thrives up to 6 to 18 inches in the soil, which can even reach up to 10 to 15 feet. It blooms yellow flowers that finally turn into whitish puff balls. These puffballs contain fine hairs that consist of hundreds of seeds, which the wind can readily carry miles for germination.

This aggressive grower is the most recognizable hazardous weed that invades suburban lawns in the U.S. and many other countries. Dandelions can reduce the aesthetic quality of your lawn and turf grass, which makes them a weed pest in the gardens. This weed will eventually spread and take over your garden. For this reason, you must kill the dandelions as early as possible.

Lawn mowing may be the best way to get rid of most weeds, but when it comes to dandelions, mowing is never a permanent solution. In dandelions, the buds that develop from the upper part of the root yield a crown that can regenerate even when you cut off the top section of the dandelion. As tiny as 1-inch root sections can generate new plants. If you use a mower to cut off the dandelion, it will eventually grow back and even multiply. There are other different ways to kill the dandelions.

Best Way to Kill Dandelions

You can permanently get rid of dandelions by either hand pulling them one by one or by using herbicides. Herbicides are useful in controlling a severe or persistent infestation of dandelions. Weed killing herbicides are of two types, selective herbicide, and non-selective herbicide.

  • Hand-pull

If only a few dandelions have grown in your lawn, hand-pulling is an effective and simple way to eradicate them. You can dig the dandelions out using a dandelion digger or a weeding fork, which you can get from garden centers and nurseries. Before you hand-pull the dandelions, make sure the soil is moist and soft. You can do it after watering the infested area or after it rains.

It’s vital to remove at least 4 to 6 inches of the dandelion root to prevent the remaining root portions that are still intact to the soil from regenerating new leaves and buds. In case any of the dandelions come back, hand-pull them again. You might have to pull out the dandelions a few times until they stop growing back.

  • Selective Herbicide

A selective herbicide will kill only certain types of plants but not others.  Herbicides that are labeled for broadleaf weed control in lawns, for instance, will eliminate only broadleaf weeds such as dandelions, but will not eradicate other desirable plants and grasses. 

A selective herbicide is best if your garden has other valuable plants and herbs that you want to keep while killing only the dandelions and other weeds. However, selective herbicides may not be as potent as the non-selective herbicides and may need multiple applications for significant effect.

  • Non-selective Herbicide

Non-selective herbicides can kill or damage all types of plants. This type of herbicide is useful for eradicating weeds growing in cracks on driveways and sidewalks and along fence rows.

The non-selective herbicides are risky to use in lawns where desirable plants and weeds such as dandelions grow side by side.  In such conditions, you must be very careful only to treat the weeds and not let any of the herbicide come in contact with other plants.

Now you must be clear that the best and easiest way to kill dandelions is to use herbicides. If you need to get rid of the dandelions in your lawn effectively, you must have the right herbicide for the task. As there are hundreds of products available on the market, it’s quite tricky to choose the right one, particularly if you are buying it for the first time. And unfortunately, many herbicide brands even brag fake promises.

There are certain factors that you can consider while choosing a dandelion killer to make sure you don’t end up with the wrong product. To help you with this, we have carefully analyzed the best herbicide brands and made a list of all the essential aspects that you should keep in mind while buying a dandelion killer, along with the reviews of some of the best dandelion killers available at present.

Factors to Consider While Choosing Dandelion Killer

Given below are some of the vital facets that you should always keep in mind while buying a dandelion killer.

1. Organic or Inorganic 

Dandelion killers or herbicides are generally available in two categories, which are organic and chemical. Each type has its pros and cons.

  • Organic

The organic killer is eco-friendly and safe. This type is great if you have pets and children, as it won’t cause any harm. However, it may take a little longer to be effective, and you may need to apply the compound more than once.

  • Inorganic

Inorganic or chemical compounds work incredibly well and are much better when it comes to effectiveness. But when you use this type of dandelion killer, you should also consider the safety of your children and pets as most chemical dandelion killers are not safe. You might have to keep your children and pets away from your lawn until the chemical has entirely dried or washed away.

2. Pre-emergent or Post-emergent

Herbicides or dandelion killers are again available as pre-emergent or post-emergent.

  • Pre-emergent

By using a pre-emergent dandelion killer, you can attack the dandelion seeds before they germinate in your lawn. A pre-emergent dandelion killer will help you prevent the dandelion seeds from developing into plants.

Basically, by doing this, you are hindering the growing process of the dandelion and trying to get rid of the problem before it occurs. Winter and fall seasons are the best time to apply this in your lawn. Nevertheless, the pre-emergent dandelion killer is useless if the plants are already growing.

  • Post-emergent

The post-emergent killer is useful in killing the existing dandelion plants and are quite effective in controlling an extreme infestation. However, it can’t stop the seeds from germination and growing into new plants.

If you are unable to decide between the two, you can get a two-in-one dandelion killer that works for both pre-emergent and post-emergent applications.

3. Effectiveness and Durability

Some dandelion killers may take much longer to show its effects. In this case, if the herbicide is not weather-proof, elements like rain and harsh sun rays can dilute or weaken the effectiveness of the dandelion killer. So, we would recommend you to go for a dandelion killer that is not only highly effective, but also water-proof and sun-proof, so it can do what it’s intended for without being hampered by any weather elements.

4. Quantity

The quantity of the concentrate that you get determines your overall purchase value. The higher its volume, the better value for money you get per ounce. For instance, one gallon of herbicide may be costlier than a quart but will be less pricey than four quarts. If you consider your future requirements, you may preferably want to purchase a gallon rather than a quart. This way you can save a lot of money. 

5. Dose Size

It’s another factor that determines the value of a dandelion killer. Highly potent herbicides can achieve a lot with only a couple of tablespoons mixed in three to five gallons of water, whereas some less expensive killers may need half a quart to obtain the same outcome. The stronger the herbicide, the more value for money, so always check the dose size before purchasing a dandelion killer.

6. Liquid or Granular

Most dandelion killers are available in liquid form that needs spraying with a hose. However, you may also come across granular or pellet herbicides. Granular killers are easy to apply, but animals can easily consume these granules, which makes these inappropriate for pet owners.

7. Persistence

If you are purchasing a selective herbicide, you may want to consider this feature. The persistence of an herbicide depicts how long the herbicide will remain active after its application. If the product has a lasting effect and it helps inhibit further growth, then it’s persistent.  The herbicide that doesn’t prohibit future growth is labeled non-persistent.

8. Temperature Threshold

Some dandelion killers may not work in exceedingly hot temperatures, so you should make sure that the product you choose works well in your region. The temperature threshold for most weed killers ranges between 90 to 100 degrees, while some brands max out at only 80 degrees. Always consider the average temperature in your location while purchasing a dandelion killer.

9. Multipurpose Weed Killer

If you are looking for herbicides that not only kill dandelions or broadleaf weeds but can eliminate other undesirable weeds as well, then a multipurpose weed killer is an ideal option for you.

With a multipurpose weed killer, you will not have to purchase different products for killing different weed species.

10. Child and Pet Safety

Some chemicals may be toxic to humans and animals, specifically children. So, make sure that the product you choose is safe to use around pets and children, as they are at high risk of accidentally ingesting the chemical when it’s applied on the weeds in your lawn. Always check and follow the warning labels.

11. Others

You can also check for other exclusive features such as hose port and automatic trigger for attaching the hose to the container of the concentrate directly and effortless pumping. Some brands even provide measuring syringe for accurate application.
