The answer to your query of how long does it take weed killer to work depends on multiple factors. In general, it takes around two to four weeks to completely get rid of weeds. However, the most prominent factor on which the time to kill weeds depends is the type of weed killer being used, which is discussed in details below:

Broadleaf Weed Killers:

If your garden is filled with broadleaf weeds, it’s high time that you start getting your hands on broadleaf weed killers. There is also an option for you to choose a weed and feed product that are known for combining grass fertilizer with broadleaf herbicides.

However, for both options, a little patience is required since you will start seeing the results after 5 to 7 days. Also, for complete elimination, you may need to wait for two or more weeks.

Roundup Weed Killers:

If you don’t like waiting and are looking for immediate results, roundup weed killers are your go-to option. Once you spray the standard roundup on the weeds, you can expect to see the results between two to six hours as the plants sprayed by roundup weed killers will start getting wilt and yellow.

However, you can’t expect to get rid of weed completely in six hours, as it may take up to two weeks to eliminate the weeds from the root system.

Pre-Emergent Weed Killers:

One of the quickest weed killers you can get your hands on is pre-emergent weed killers. Although the results may be invisible, they start killing the weeds just after a few hours of application. So if you are impatient and want to get rid of the weeds as soon as possible, pre-emergent weed killers are one of your go-to options.

Grassy Weed Killers:

The grassy weed killers usually come with a special ingredient named Glysophate, which is a powerful and popular weed killer. When you use this kind of weed killer, you will see fast results that may show wilting within hours and complete eradication and killing of weed within 1 to 3 weeks.

However, for the weed killers containing Glysophate, you have to be very much careful because it is one of the non-selective herbicides that may end up killing your plants. Therefore, it is essential to take proper precautions and instructions before using it.

How do weed killers work?

Read the weed killer label and instructions properly to know the steps to follow very clearly.
When you feel the air is calm, start spraying the herbicides. If the air is not calm, make sure to use a gel-type herbicide so that the particles do not drift.
Use a foam applicator and target only the weeds you want to.
Don’t forget to wear PPE, especially hand gloves, since hands are the most prone to contamination.
Now calibrate the sprayer at the recommended rate by the company.
Calculate the amount of herbicide to be added to the tank as recommended by the company’s instructions.
Make sure that you fill the sprayer with half the volume of water. Start with moderate agitation and continue as needed. Once mixed, don’t add further agitation.
Check the label for nozzle suggestions, and then use the same nozzle as recommended.
Maintain the spray height to be almost two feet above the plants you are going to spray on and start spraying.
Clean off all the equipment after you are done with spraying.

Every weed killer comes with instructions to use, which are supposed to be followed strictly to get the best results.
