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;
