Disadvantages Of Using Vinegar To Kill Weeds

Best liquid hose end lawn weed control power rankings
  • Yes, it looks like a great weed killer for lawns, but it is not practical in lawns that are vastly invaded with weeds.
  • It might not be very effective for controlling perennial weeds since they appear as though theyre dying only to re-appear from the roots.
  • At such high concentrations above 11%, vinegar is extremely dangerous and can cause serious skin burns, blindness, and irritation.
  • Household vinegar, usually at much lower concentrations, cannot kill weeds effectively.
  • Vinegar is not suitable for controlling weeds in large areas. You cannot also use it as a commercial weed killer.

Overall, I would recommend using vinegar as a natural, organic or pet-safe weed killer for your lawn. However, be careful not to cause corrosion on your driveways, patios, and other areas where you apply this herbicide.

Best Weed Killer For Lawns Reviews

Here are my top picks of the best weed killer for lawns. Ive taken the time to review and test each one extensively so that I can bring to you an informed choice so that you can get your green space looking its absolute best.

Knowing weeds in lawns as I do I will continue to have the opportunity to re-test and update this list with the latest revisions and any new-to-market products. In the meantime, heres my rundown of the best herbicides on the market right now.

Best Ready To Use Spray

  • Ingredients: Glyphosate, Diquat
  • Contains two powerful active ingredients that work together to target the eradication of weeds
  • Ready-to-use formula can be used as a spot control treatment or larger scale weed clearance
  • See results in as little as 12 hours

Cons

  • Not effective on all common varieties of invasive plant

RoundUp is a name synonymous with herbicides, so, not surprisingly, I had to test their selective herbicide weed killer for myself. Equipped with safety gear I was able to give this a try both as a concentrated spot control formula for broadleaf weeds on my driveway by using the wand spray applicator, and also diluting the concentrate into a backpack weed sprayer for wider coverage of grassy weeds and broadleaf weeds in my lawn.

This herbicide is ideal for clearing large lawns quickly and its performance was phenomenal. It killed the majority of the weeds within 17 hours and the dead weeds were easy to uproot a day after the application.

Organic Vs Synthetic Weed Control

The term organic is an unofficial, lightly regulated word that references something natural. It involves using ingredients present in nature to make an herbicide with similar effects as its man-made chemical or synthetic counterparts.

Generally, organic herbicides are safer than synthetic weed control products. However, as Ohio State University reports, there are highly toxic organic lawn weed control products on the market. With that in mind, always exercise caution when selecting, using, and storing any weed control products, and read the label to familiarise yourself with all of the associated hazards that come with using these types of products.

Organic Herbicides

Organic herbicides range from homemade concoctions to pre-mixed, store-bought solutions. Homemade solutions are generally inexpensive, depending on whether you have the ingredients to hand or if you need to buy-in. Store-bought solutions are often pricier than their synthetic counterparts since they contain natural ingredients that are not mass-produced.

Benefits

Organic varieties are generally safer to use in terms of causing harm to people and pets if spillages occur. This is because the ingredients they contain are mostly natural. Id strongly advise against ingesting any type of lawn weed killer however and always seek medical advice if either spillages or ingestion occurs.

How To Apply Weed Killer For Lawns

Top 5 Best Liquid Lawn Fertilizers [2021 Review]

You must apply your weed killer correctly for best results. Thus, before using the herbicide, thoroughly read its label and take note of:

  • Shelf life
  • Research the active ingredients.

Armed with the right information, ensure a precise dosing accuracy for an effective treatment.

Before measuring and mixing the herbicide, check that the weed conditions meet the specifications on the label. For instance, are they small and actively growing? Are their root structures powerful and well-functioning? Are they among the target weeds listed on the label?

Check the temperature of the soil and outdoor air. Generally, the best weed killers for lawns work best in temperatures between 60°F and 77°F. The subsoil housing the root structure should be at least 53°F or higher.

If your lawn meets all the requirements, go ahead and apply the correct dosage while following the application method recommended by the manufacturer.

Wear protective gear when applying herbicides. That includes protective clothes, respirators, rubber gloves, and goggles. Finally, clean the sprayer or spreader thoroughly to remove the product residue. Clean up and dispose of any disposable items.

Ortho Groundclear Vegetation Killer Concentrate

Overview

This is a non-selective herbicide and is highly effective at killing weeds of all kinds. An all-rounder product takes care of both pre-emergent and post-emergent weeds equally well. Once you apply the chemical, very soon, you will notice the shrinking and wilting of leaves. Moreover, the liquid also reaches the root system, and this ensures that the complete weed plant dies, and there is no way it can again sprout.

Once killed, the weeds will not grow in the treated area for up to 12 months or maybe even more. If there is continuous heavy rainfall, then it is recommended that you apply the herbicide once in 6 months. A 2-gallon pack is enough for an area of approximately 600 square feet. The two active ingredients in this product are glyphosate and imazapyr.

Pros

  • Long-lasting and effective for a long time
  • Kills the weeds and prevents new ones from growing
  • Great for hard surfaces like walkways, pathways, and patios

Cons

  • Due to its nature, you will get limited coverage

Ortho GroundClear is an effective weed killer and will clear the ground for you to plant what you want to. It works as both a weed killer and a weed preventer.

Bring Out The Weed Whacker

There are also powerful tools that you can take to the problem. For example, weed whackers.

These devices are carried by hand and use a motorized plastic cord to trim the pesky weeds down to the same length as your grass, making them less conspicuous.

But they wont completely get rid of them as they dont affect the roots. So regular use is required because weed growth will continue.

The Biggest Reasons For Lack Of Success With Weed Killers

People fail with concentrated weed killers for one of two reasons

  • They mix them too strong so they kill the grass
  • They mix them too weak so they dont kill anything
  • There are several reasons why you might not dilute a concentrated weed killer properly.

    Firstly, many people make a stronger mix than necessary because they believe it will kill stubborn weeds quicker. It wont, itll just kill the grass too.

    Secondly, many users dont get an accurate measurement of their lawn. They completely underestimate how big their lawn is and only use enough concentrate for 30 square meters when in fact their lawn is 50 square meters.

    To ensure success, always measure your lawn so you know how much concentrate you need to mix in how much water. And always dilute the concentrate as per the manufacturers instructions.

    That way, you cant really go wrong.
