Weed And Feed: What Is It Really?

The term “Weed And Feed” is a casual phrase that is used to indicate a type of chemical that can kill both weeds and pests. Using weed and feed on your lawn, you can get rid of disturbing pests and unnecessary weeds very fast. 

After using weeds and feeds, the main benefit you get is that your lawn grasses can grow much faster. It is because they can absorb a larger amount of water and nutrients when there is no presence of unnecessary weeds.

If you go on applying weeds and feeds for a couple of days, then your grasses will grow to a larger size. Which in turn will choke the unwanted weeds to grow anymore. This means you will gradually have to use a lesser amount of weed and feed because your grasses will slowly start preventing the weeds themselves.

Working Speed: How Long Does Weed And Feed Take To Work?

Well, you’ll usually see most weeds and feeds showing full results within 14 days of applying them. However, the fertilizer part of the chemical will start working as soon as in 5 days. As more weeks pass, you will visibly notice the results more prominently.

To discuss in detail, different types of weeds and feeds take different amounts of time to show effect. We have cited the expected working time of each type in a segmented manner below:

  • POST-EMERGENT Weed And Feeds: This type of formula used when you already have weeds growing in your lawn, is called POST-EMERGENT weed and feeds.

This formula of weed and feed works only when the weeds have grown to a certain degree. A POST-EMERGENT formula takes full effect within about 21 days. After 21 days, the weeds in your lawn will completely disappear.

  • PRE-EMERGENT weed and feeds: The pre-emergent formula is used to prevent weeds from growing in your lawn before they can even be born. Also, this chemical formula is fully effective for a lawn that already has the weeds fully under control.

By this formula, the killing happens when the weeds are in the germinating stage. So it is recommended to apply pre-emergent weed and feed at least 6 weeks before spring. It will take around six weeks to fully get rid of the dormant seeds of the weeds. 

Full Annihilation Of Weeds

If you use weed and feed products for several years, it is possible to fully get rid of all the weeds permanently. Even for an expert gardener, it takes at least 5 years to fully annihilate all traces of the weeds. This result is achieved if you carefully apply the weed and feed at the proper time every year.

After several years of treatment, if you see no weeds growing for 6 months, you can be sure that your lawn is completely rid of unnecessary herbs.

What Factors Can Reduce The Effectiveness Of Weeds And Feeds?

If you are experiencing no results even after applying weed and feeds to your lawn, maybe there’s an error in the using method. 

But, remember, if you consider using weed and feed in hot seasons, the effectiveness of this chemical will drastically reduce.

Plus, avoid using post-emergent weeds and feed right after mowing the lawn. In order to get the best result, you have to wait a few days after mowing the lawn to apply the weed and feed.

You can also choose to apply weeds and feeds one day after it has rained. The soil should be damp, but you should not water the lawn after applying weed and feed.

When Is The Right Time To Apply Weed And Feed?

For pre-emergent weeds and feed, it is perfectly fine to apply whenever you’re free throughout the day. The working mechanism of pre-emergent weed and feed is to create a soil barrier to stop the sprouting process of the weeds.

For the post-emergent formula, you have to carefully read the package label to decide which weed and feed it is. Because there are 2 types of post-emergent formulas available out there on the market, such as systematic and non-systematic.

Non-systematic weed and feed can be applied any time of the day because they work by physically attacking the plant tissue of the weeds.

The Systematic type of post-emergent formula of weed and feed works by attacking the roots, which will eventually prevent the growth of the weeds. So, you should apply this type of herbicide only in the selected areas where weeds are growing. It is better to apply these in the morning.
