Buyer’s Guide Top Five Granular Weed Killers

How do you know which weed killer product is best for your garden or yard? You may want a combination of products to get year-round results. Perhaps you are the one who wants to get outside the first time the weather is nice and treat the yard. Maybe a weed killer to use on existing weeds is most important to you. Below are some general questions and answers about weed killers.

How often do I need to reapply the product

Each of these items requires different application times and circumstances. It is imperative that you read the manufacturer’s instructions carefully. Following them exactly as the maker suggests is our biggest recommendation.

Can I let my animals in the yard right after I put down the weed killer

No. To properly apply the chemical and activate it, most of these products require water. To prevent any harm to your animals, it is important that these granules sink into the soil, gravel, or grass and dry out again.

Do this product kill zoysia

Yes. Most of these weed killers cover this pesky growth. You can effectively control this weed by applying a weed preventing chemical like The Anderson’s Pro Turf Barricade. Then, you do not have to kill the weed after it grows because it never breaks the soil.

How to apply a granular weed killer?

Such a herbicide requires watering two days after treatment, and its effect will be visible only after 1-2 weeks. Liquid herbicide works faster, but its application requires a garden sprayer, special rubber gloves, and when used, it is necessary to protect useful plants on the lawn. I recommend applying a granular weed killer from mid-May to early August.

I would recommend buying a selective granular herbicide. But keep in mind that they won’t affect all types of weeds. Many experts recommend the use of herbicides along with nitrogen-containing fertilizer because such a product increases the weed killer’s efficiency. With this treatment, the fertilizer must be applied a week earlier than the powder herbicide. You may mix the liquid herbicide with liquid fertilizer and use them together, but if the fertilizer is granular and the herbicide is liquid, apply it only a week after the fertilizer.

Our last take on granular weed killers

This list offers a diverse product range because your yard has different needs. You may need a vegetation killer to keep weeds out of your gravel driveway. You might also find a yearly herbicide important for keeping dandelions and crabgrass out of your yard. Using an outdoor pesticide is also important for minimizing ant problems and issues with centipedes and spiders. Therefore, you may want to purchase a few of these products for your shed or garage.

Are granular weed killers effective? One of the readers of Grass-Killer.com asked me this question. I firmly say “yes” because liquid herbicides are good but their granular analogs provide a more selective effect.

Many farmers and gardeners have proved the effectiveness of granular weed killers, especially for large territories. Efficacy of granular or powder herbicides depends on:

  • Compliance with the dosages recommended by the manufacturer;
  • The suitable air temperature (16-22 degrees) and the irrigated soil;
  • The moisture soil layer;
  • Growth activity of weeds – the higher they are, the better they are affected by a chemical herbicide;
  • Phases of weed development – young plants die faster;

What granular weed killers you may buy?

  1. Ortho is good for 3-month protection. It is a very cost-effective 10 lb. bag for 10,000 sq. ft.;
  2. Scotts is a good weed killer that may feed the grass and kill the unwanted vegetation. But do not apply it on Bermuda grass;
  3. The Andersons product is good for killing over 30 weed types in early spring;
  4. Snapshot 2.5 covers up to 1,000 sq. ft. and may save your lawn from the weeds up to 6-8 months. Apply before the rainfall or irrigation;
  5. Lilly Miller may cover up to 1,000 sq. ft. up to one year of weed control;

Granular Weed Killers FAQ

What is the best grass killer on the market?

It is hard to define the best of the best weed killer on the U.S. market because all these products have different formulas and methods of action. 

The kind of weed killer you use will determine where you apply it, where you apply it, what kinds of weeds it will kill, how it can affect surrounding plants, and how long it can keep weeds under control.

When selecting the best professional weed killer for the task, consider the following properties required to maximize product efficacy and reduce the chance of herbicide failure:

  1. Pre-emergent products (also known as weed preventers) aim and kill weed seedlings that are sprouting until they grow from the soil as visible weeds. They’re usually applied to the soil of lawns or gardens until you see weeds. They provide a chemical barrier in the upper soil layer that stops seedlings from growing underground, effectively destroying them;
  2. Post-emergent remedies. Adult weeds that have already grown from the soil are controlled with post-emergent solutions (also known as herbicides). Apply the chemicals to the leaves and/or stems of noticeable weeds in garden beds, driveway or pavement cracks; the chemicals can kill the weeds by crushing the vegetation or stems, or by going down to the roots and damaging the whole root structure;
  3. Selective weed killers destroy species but leave turfgrass and other useful plants behind, making them a decent choice for getting rid of dandelions or thistles on the turf or in a flowerbed;
  4. Non-selective weed killers for lawns kill weeds as well as all other plant species in the application area. Use them around the fence or lake, as well as in driveway or sidewalk holes, where beneficial plants would not be harmed;
  5. Systemic herbicides. After being absorbed, systemic products travel within a weed, typically down to the roots, killing the whole plant from the ground up. You should expect to see results in a few days to a few weeks, but unlike touch weed killers, systemic drugs don’t usually specify how long they take to kill weeds. They’re an excellent choice for annual weeds like dandelion, poison ivy, and ragweed, which are notoriously difficult to kill due to their deep roots;
  6. Contact weed killers do not travel inside a weed until entering it; instead, they kill the weed by removing the plant component on which they are applied, normally within hours to days of use. Crabgrass, nettle, and chickweed are examples of annual weeds that are quicker to destroy than perennial plants that fail when the leaves or stems are killed;

According to user feedback, these commercial products are quite common in their weed control categories: 

  • Post-emergent – Green Gobbler Vinegar Weed & Grass Killer;
  • Pre-emergent – The Andersons Barricade Granular Weed Preventer;
  • Contact – Spectracide Weed & Grass Killer Concentrate;
  • Non-selective – Roundup Weed and Grass Killer Concentrate Plus;
  • Selective – Southern Ag Amine 24-D Weed Killer;
  • Systemic – Ortho Nutsedge Killer;

What will kill clover but not grass?

The most effective methods for killing clover and saving the lawn grass at the same time: 

1) Vinegar solution. For this safe home cure, make a DIY non-toxic weed killer:

  • Combine one cup of vinegar, one cup of water, and one droplet of dish soap in a mixing bowl;
  • Shake it well before spraying it on clover patches. The vinegar will dry out the clover leaves, whilst the dish soap will ensure that they stay there;
  • To kill clover completely, you will require to spray over a period of weeks;
  • Sad to say, the vinegar will damage turf, so use caution when spraying the remedy;

2) Organic herbicide. You could, for example, use the ADIOS targeted, organic herbicide to kill clover while leaving the grass alone. Just spray it on clover to weaken and kill the weed.

3) Organic fertilizer. Clover would be less attracted to your grass if you use an organic nitrogen-rich fertilizer that releases slowly. Traditional, slow-release fertilizer is preferred by certain homeowners since it grows vegetation faster and costs less. In the end, however, applying organic fertilizer can result in healthier growth. Guano, cow manure, bone meal, blood meal, liquid kelp, earthworm castings are popular organic fertilizers.

If you’re picking the clover by hand, smooth the field by watering it and letting it soak for an hour or two.

What is the best herbicide to kill chickweed?

However, many herbicides kill chickweed on touch and are better used in the early spring to discourage seeds from developing. Chickweed may be eradicated with a non-selective herbicide that attacks the root system and kills the whole plant.

Remove chickweed from the field in lawn areas to reveal the dirt. After that, use an aerator or a shovel to aerate the dirt. If you’re using a shovel, make gashes in the ground that are at least two or three inches wide and one to two square feet long. To get rid of chickweed, apply a fertilizer and weed killer mixture to the infected field.

For example, the Ortho WeedClear Lawn Weed Killer RTU products may be used. This product can kill chickweed but will not damage your lawn if used as instructed. When chickweed is vigorously developing in the spring or fall, apply as directed on the bottle.

What kills weeds permanently?

Grass and weeds may be destroyed in a number of ways. Permanently killing them, on the other hand, is a daunting task. To permanently kill some kind of grass or weed, you must strike and kill the plant’s roots.

Use detergent, Epsom salt, and dish soap to make a homemade weed killer. This non-toxic grass and vegetation killer is simple to create. Get rid of weeds in your garden without using Round Up with these easy-to-follow recommendations that will kill grass and weeds for good. Vinegar-sprayed weeds can die easily, usually within 24 hours.

Covering weeds is perhaps one of the most efficient and cost-effective methods to avoid them. Weeds cannot thrive in the absence of sunshine and space to grow. Mulching is a common practice that can also help boost the health of your soil.

Glyphosate is the world’s most commonly used weed killer, and it is strong, clean, and effective at eliminating most weeds with only one use. It destroys right down to the roots, ensuring that they do not regrow after only one use. It kills 99 percent of weeds in the yard, even stubborn ones like brambles and ivy.

What do professionals use to kill weeds?

Most professional services and gardeners use chemical herbicides for weed control. Mostly, these are non-selective and selective products. Non-selective herbicides are intended to kill any plants they come into contact with, while selective herbicides are only made to attack certain weeds.

Also, experts mostly use the strongest ingredients to achieve quick and effective results in the shortest period of time. Keep in mind that these active components can be quite dangerous to your lawn, pets and kids. Hire a professional if you are not sure how to apply a powerful herbicide. 

The strongest components in weed killers:

  • Glyphosate. It’s found in parks, fields, and public spaces all over the country. Glyphosate is an extremely successful and powerful weed killer. It is systemic, and it can kill grass and pretty much every other plant it comes into contact with. This product kills all annuals, perennials, woody perennials, and tree stumps;
  • Vinegar. This herbicide is widely used at home. Salt and dish soap are sometimes used in combination. A non-selective weed killer performs best in hot weather. It will harm your soil’s PH levels if you use it too often. It works well on small weeds, however big weeds like brambles will need commercial amounts. Overall, this is a fine, inexpensive homemade weed killer that works well for tiny weeds and small plots;
  • Triclopyr. Woody weeds such as brambles, nettles, and invasive saplings are targeted with this selective weed killer. It’s been formulated to not kill vegetation and can be easily used in turfed fields. In a knapsack or sprayer, it’s usually combined with water, although it may even be found in a watering can. One disadvantage is that it can stay in the soil for up to 6 months, preventing replanting. This powerful weed killer destroys anything it comes into contact with;

What is the best way to get rid of crabgrass?

Regrettably, keeping crabgrass control necessitates weeding the lawn on a daily basis. Weeding can be performed in the late spring until the crabgrass plant matures and produces seeds. This method works well after rain, when the soil is damp and warm.

Also, you may use different chemical and all-natural herbicides. A pre-emergent herbicide is the most effective agent in the fight against crabgrass (a.k.a. crabgrass preventer). It’s best to do it until the crabgrass seeds sprout in the morning. The granular herbicide functions by forming a chemical membrane on the soil’s surface. The herbicide is absorbed by the seeds when they germinate, and they die.

In the fight against crabgrass, this is the most successful and cost-effective method. Pre-emergent products inhibit full germination by interrupting the growing phase.

Once crabgrass has established itself in your yard, it’s time to broaden your horizons. Post-emergent herbicides attack the plant directly, destroying it so it can reproduce further seeds.

If your lawn just has a few crabgrass trees, you can use a ready-to-use tool like Scotts Spot Weed Control for Lawns to handle them. When used as instructed, this spray kills mentioned weeds, like crabgrass, right to the root without damaging your lawn.

Search for one of the following active compounds:

  • Dithiopyr;
  • Prodaimin;
  • Oryzalin (for a warm season);

  1. We’ve finally bought our first house and the weed situation drives me insane. The thing is, we have two dogs that are constantly playing around in the backyard so I need something that is safe to use around pets. What I’ve found so far seemed effective but it was way too toxic to be used around dogs. The Scotts weed killer seems a great option but can you please let me know how long do you think I should wait before letting them out again? Thanks!

    1. Hello, Eva! Thanks for the comment. I would recommend to wait 4-6 days.
