Top 10: Best Dandelion Killers
This dandelion killer comes from one of the top names in the business. It uses triple action technology to destroy both the existing weeds and the ones below the surface. The formula then keeps weeds from returning for a maximum of four months. It also has fertilizer to feed your lawn and make it lush and green.
When you apply the dandelion killer, you should keep your pets and other people out of the area. It's important that nobody enter the area until the spray has settled, since it can be harmful to breathe.
The formula is best used in the early or late spring, once the temperatures are consistently between 60 and 80 degrees. When this occurs will depend on your location. It works best if it's used before your third or fourth lawnmowing session.
With that said, you should make sure not to apply the formula to any areas that have new seeds or sod. Wait until after the fourth mowing to do this. The product should be applied when you see active dandelion growth, rather than as a preemptive measure.
After each application of the fertilizer, you must wait a minimum of six weeks before applying it again. It's better to wait for eight weeks. One package can cover a maximum of 4,000 feet. If your yard is smaller than that, you can use several applications throughout the season without needing a replacement.
The formula includes a weed control component for weeds that haven't emerged yet and weeds that have. If you only use formula that kills the existing weeds, you won't get rid of the ones that are still in the ground.
The dandelion killer works on a variety of different weeds. It will kill ryegrass, Kentucky bluegrass, fine fescue, centipede grass, and several others. If you apply it correctly, it can kill active broadleaf weeds like dandelions, but it's not able to kill active crabgrass.
This formula is built specifically for Northern lawns that often have to battle grasses like ryegrass and Kentucky bluegrass. Using it doesn't take much preparation. All you need to do is measure your lawn with the My Lawn app from Scotts. Then you can measure out a proportional amount of weed killer and go to work.
This is another Turf Builder product from Scotts. It's capable of covering even more ground than the previous option, with the ability to clear weeds from 5,000 square feet of land. You also have the option to buy a two-pack for 10,000 total feet of coverage, or a pack with enough for 15,000 feet.
The model allows for control over your clover and dandelions, whether they're in your yard or your garden. Thanks to the Weedgrip technology, the formula gets rid of the weeds below the surface and above the ground.
Like the previous option on the list, this model also works as a fertilizer. Once it gets rid of the weeds, it helps to fertilize and nurture your grass so that your lawn is thicker and lusher.
This Turf Builder model is built for the mid to late spring. You can use the Scotts app to determine how large your lawn is. The formula also kills the grasses that the previous option did, like ryegrass and centipede grass.
This formula is specifically designed to kill weeds without killing your lawn. Not only does it work for dandelions, but it also works on clover, crabgrass, nutsedge, and other northern grasses.

The formula begins working immediately with a single application. To get the best results, you should use the spray each time you notice that weeds have begun growing in your area. The design is friendly to your lawn, killing the weeds without killing the lawn itself.
Another notable feature is that this formula becomes rainproof in just an hour. The other rainproof formula on the list takes three hours.

You can also get the One Touch Sprayer from the manufacturer to make application easier. Once you attach the spray nozzle to your garden hose, you can simply turn on the water and then spray the formula without needing to dilute it at all.

There are a number of different dandelion killers on the market. Some are built for your lawn while others are built for your garden. Some will kill other grasses, while others focus on dandelions and clover alone. Some are meant for spot treatment, while others are meant for wide application.

You will need your own nozzle, though.
If you need an organic solution, the Green Gobbler option is the way to go. This natural weed killer uses vinegar to target grasses and weeds on pavement and other areas. Just keep in mind that it will kill plants other than dandelions, so you shouldn't use it on your lawn or on a flowering garden.

Frequently Asked Questions
Dandelions are pretty flowers. Many people don't mind having them in their lawn. But they can pose a serious problem to the plants surrounding them. The roots dig deep into the soil and steal water from the surrounding flowers and plants.
If you have dandelions in your yard, your grass won't be able to thrive. It doesn't have room under the soil to grow.
In theory, you should be able to get rid of a plant by pulling it up by the roots. But dandelions are especially tricky plants. The roots tend to go deep, and they may spread out. If you only get part of the root, the flower may begin growing again.
There are some tools that are built specifically to target dandelions. Dandelion pullers and slim trowels are both ideal. But if there are a lot of dandelions in your garden or lawn, sometimes the easiest way to deal with them is by using weed killer.
Digging the roots of every individual dandelion takes time. And the flowers tend to spread quickly, thanks to their windblown seeds.
Yes! There are several weed killing formulas that can target dandelions without targeting your lawn.
Some formulas are built to target crabgrass, dandelions, and clover. But they don't target other plants. If you're a fan of having wild grasses in your lawn, you might prefer these, because they don't harm the native bluegrass and ryegrass.
There are other weed killers that are formulated to kill up to 300 different plants. Many of these are designed to leave your lawn intact. Some even have fertilizer to help your grass grow back more thickly.
Just be wary of vinegar solutions, which will kill any plants without discriminating. Those should only be used on pavement and barren areas.
