The Best Weed and Feed for Your Lawn in 2021

Nothing beats having a lush, green lawn. Unfortunately, lawn upkeep can be quite a time-consuming— and sometimes quite a confusing— task. Plus, who likes pulling weeds anyway?

With the help of the best weed and feed fertilizer, you can spend less time pulling weeds and more time actually enjoying your yard this summer. These time-saving lawn fertilizers don't just keep your grass looking thick and lush; they help kill weeds and prevent them from regrowing.

To help you keep your lawn looking its best, we've highlighted the best weed and feed products of 2021 below. To ensure every lawn is fully accounted for, we've included granular, liquid, all-natural, and Southern formulas.

How do weed and feeds work?

As the name suggests, weed and feed act as both a weed killer and a fertilizer. The 'weed' component of weed and feed is an herbicide that kills pesky weeds and acts as a weed preventer. The 'feed' component is a fertilizer that adds vital nutrients like nitrogen, phosphorus, and potassium to the soil and supports plant growth. Together, they make maintaining a healthy green lawn easier than ever.

How do you apply weed and feed?

Application varies depending on the type of product being used. Most fertilizers are granular and can be spread using a hand-held or broadcast spreader. Liquid formulas typically come with a sprayer for easy application. Try your best to spread the product evenly across your lawn and avoid concentrating on certain areas, even if they contain more weeds.

For the best results, apply to damp grass that's between three to five inches tall. Users should water their lawn one day before application and wait at least two days after applying to water again. This allows the product to fully soak into the lawn and be absorbed by the troublesome weeds you're trying to get rid of.

Before purchasing weed and feed, it's crucial to check which variety of grass you have growing on your lawn. Certain products are not compatible with some grass species, most commonly those grown in Southern states, and can cause serious damage to your lawn. If you're unsure of what grass variety you have, test a small patch of your lawn before attempting a full application.

How often should you use weed and feed fertilizer?

As a rule of thumb, weed and feed should be used only two to three times per year. Applications should be made at least two months apart. The first application occurs during spring when weeds first begin to pop up. The next occurs in late summer or early fall to provide your lawn with the nutrients it needs during the colder months ahead.

Every product is a bit different, so users should always check the package for instructions on how to use that particular product to achieve the best results.

Is weed and feed products safe?

In order to effectively kill weeds, most weed and feed products contain strong herbicides made from chemicals that should not be touched or inhaled. To adhere to government regulations, products are safety tested. However, these tests do not show the long-term effects of exposure or how the ingredients impact the surrounding environment.

As the instructions recommend, leave your lawn to rest for at least a full 24 hours after application. It's imperative to keep children and pets off your grass during this time. Do not use weed and feed products near your garden or any other edible plants in your yard.

If you're at all concerned about the potential negative environmental and health effects, try an organic weed and feed product that doesn't contain synthetic chemicals.
