5 Best Dandelion Killer Spray For Your Lawns

Even the most impeccable lawns will have the occasional dandelion. Dandelions are weeds that spread with devilish speed and can choke your grass and flowers. If they’re not taken care of from the root of the problem (quite literally!), they can grow right back.

Thus, the best way to confront the dandelions in your lawn is to kill the whole plant, root and all. This cannot be done by just hand-plucking them off the ground since their taproots usually grow up to 3 feet underground.

Here’s where dandelion killer sprays come in handy. We would review 5 best dandelion killer sprays for your lawn.

What are Dandelion Killer Sprays and how do they work?

Killing dandelions with herbicide

There are two basic kinds of herbicides that can be used on dandelions: selective broadleaf herbicide and non-selective herbicide.

While working with herbicides, the most effective way to do so is before the dandelion actually develops flowers or else there’s a higher probability that the dandelion by then is far more resistant to the herbicide.

A broadleaf herbicide usually kills only broadleaf weeds such as dandelions and is good for usage in lawns since the herbicide only kills the dandelions and not the grass. The non-selective herbicide, however, kills any plant that comes its way. It is effective for spot-removal of dandelions.

Advantages of using a dandelion killer spray over other kinds of weed killers

Spray formulas, be it selective to a particular weed or broad-spectrum that destroys a variety of weeds, are intended to directly reach the target.

They are useful not only for lawns, but also for harder surfaces such as your driveway where cracks allow the growth of dandelions and other weeds. Spray formulas are additionally easy to use and maintain, though regular application of the formula to the lawn may be required in some cases.

Sprays also ensure that the dandelion seeds that are hidden to the naked eye are killed.

A pump sprayer helps in the even mixing of all of your contents in one place. The sprayer that’s attached to this pump makes the delivery of this concentrate a faster, easier and a more efficient process as it can be used over a range or made target specific depending on the user’s needs.

Sprays can also be used in addition to the traditional methods of hand-plucking the dandelions or other weeds to ensure better results.

What a typical pump-sprayer should look like

A good pump sprayer should have a sturdy body that doesn’t tip over. That is attached to a quality hose that doesn’t bend so as to ensure smooth flow of the substance to the end of the hose that is attached to a good quality nozzle that sprays the contents evenly and with the required stream strength.

The nozzle comes in many different types for various purposes. Many pump sprayers are now battery operated and can be recharged easily.

Depending on the requirements of the lawn, a user will typically have to spray the lawn every few months. Thus, a good dandelion killer sprayer would also require long standing materials and corrosion and chemical resistant coatings.

They should, typically, be as easy to store as they are to use. A common issue faced by spray users is a leaky nozzle but proper care and storage as well as regular replacement (if required) should do the job.
