Hand-pulling weeds on your lawn isn’t going to cut it if they’re out of control. Sure, you can pull out a few by the root, but doing so for your entire yard may be tough and time-consuming. That’s where weed killers come in, which are often the most effective method of lawn weed control. There are many lawn weed killers on the market, making it difficult to pick the best one for your lawn. We’ve prepared a list of the best natural and granular weed killers that are safe to use for your specific lawn needs, as well as how to choose them.

Identifying Weeds

You must first identify the kind of weed you’re dealing with before you can pick the best natural and granular weed killer for your lawn. Different weeds necessitate different treatments; what works for one may cause little or no harm to another. Weeds are classified into three types: broadleaf, grassy, and grass-like.

#1. Broadleaf weeds

Since these weeds have large, flat leaves, they are unlikely to be mistaken for grass. They grow in soil lacking in vital nutrients, and because they exist in several forms—annual, biennial, and perennial—different broadleaf weed varieties necessitate different herbicides depending on their life cycle.
Dandelions, ground ivy, clover, chickweed, dollarweed, thistle, and oxalis are examples of broadleaf weeds.

#2. Grassy weeds

Grassy weeds grow one at a time and have leaves that look like grass blades. Crabgrass, quackgrass, goosegrass, and foxtail are examples of grassy plants.

#3. Grass-like weeds

This weed looks like grass, but its leaves are tube-like and triangular rather than flat. Garlic, nutsedge, and wild onions are examples of grass-like plants.

How Weed Killers Work

Weed killers work by using chemicals to either kill or prevent the growth of the weed. There are numerous herbicides available to combat weeds at various stages of their life cycle—or even before they sprout. Here are the important factors to consider when selecting a safe natural and granular weed killer for your lawn.

#1. Pre-emergent or post-emergent

Pre-emergent weed killers target weed seedlings before they germinate. If weeds have already sprouted, this type will not help. Post-emergent weed killers are intended to eliminate weeds while they are actively growing. Post-emergent weed killers are applied directly to the plants’ leaves.

#2. Selective or non-selective

This is an important factor to consider. Selective weed killers destroy weeds without damaging nearby useful plants, but non-selective herbicides damage all nearby plants, even if they are beneficial.

#3. Systemic or topical

Systemic weed killers attack the entire plant, including the roots. Topical herbicides, on the other hand, only kill the plants that are in the area where they are applied.

#4. Persistent or non-persistent

Persistent weed killers remain active after application to prevent subsequent weeds. Non-persistent weed killers do not provide continuous weed control.

Natural Weed Killer for Lawn

If you want a well-kept garden and a flawless lawn but don’t want to use herbicides, we have some natural weed killer for you. A natural weed killer is usually a non-selective solution, killing whatever plants it comes into contact with, including lawn grasses. When used regularly, they can also alter the composition of the soil.

#1. Vinegar Solution

A vinegar solution is a popular natural weed killer for lawn. All you need are the following:

  • White vinegar, apple cider vinegar, or cleaning vinegar, distilled. To be most effective, the vinegar’s acetic acid concentration should be greater than 11% in order to burn and kill the plant.
  • Dishwashing liquid. This acts as a surfactant, allowing the vinegar to adhere to the weed’s surface for a longer period of time.

Shake the items in a spray bottle to mix. When the weather forecast predicts a few days of constant sunshine, use this strategy. Rain washes the vinegar off the weeds too quickly, and the most harm occurs when the sun strikes the weeds’ leaves. Spray the solution directly into the weeds, taking care not to get it on nearby plants.

#2. Rubbing Alcohol Solution

This astringent substance kills weeds by removing moisture from their leaves. Dilute one quart of rubbing alcohol with one liter of water. To make it easier to use, mix the solution in a spray bottle. As with vinegar, use it on a sunny day and spray it right on the weeds, being careful not to get it on other plants.

#3. Boiling Water

This natural weed killer is the easiest to prepare and use. You won’t have to do any mixing, and you can use it whenever you want: day or night, with or without sunlight, even in the rain.
Simply boil water and pour it onto the weed’s leaves. Use enough to seep down into the roots. To target the unwanted weed, a kettle with a spout can be useful.

#4. Propane Torch

The same effect can be achieved by scorching the middle of the weed with a propane torch, similar to how boiling water kills weeds—roots and all. There are several long-handled torches designed expressly for this purpose. Because of the long handle, you can kill weeds without stooping. Naturally, when using this tool on windy days, in dry conditions, or in brushy locations, you should exercise utmost caution.

#5. Corn Gluten Meal

Corn gluten meal is classified differently. It is a weed suppressor rather than a weed killer, making weeds impossible to grow in the first place. The most main uses of corn gluten is to manage crabgrass in lawns. It inhibits the formation of the first roots that crabgrass seeds produce after germinating. However, appropriate application requires two steps:

  • Application must be coordinated with crabgrass germination.
  • Application must take place during a dry period.

Corn gluten is an organic powder that is left over after milling corn. Simply distribute the powder over the soil to apply. After applying the corn gluten, moisten it into the soil (approximately 1/4 inch of water is required). However, after you water it in, the weather must be dry for a few days. Otherwise, the roots will not be removed.

Granular Weed Killer for Lawn

Granular weed killer is usually applied with a spreader, making it easier to cover a big area, such as an entire lawn. Granules can also be mixed with dry fertilizer to create a combination that kills weeds while nourishing the soil. Granular forms are ideal for weed killer in lawn due to their capacity to disseminate herbicide and fertilizer across large areas.
