Where Are the Weeds?

Your weed killer selection depends on where you’ll be using it because you don’t want to risk damaging healthy plants.

In the Flower Beds

When attacking weeds in the flower beds, you want products that can be applied precisely (e.g. bottles that shoot a narrow spray). Avoid misting as you risk it floating onto the good plants. If the garden is not severely overrun, you can also try to manually remove as many weeds as possible.

There is such a wide variety of weeds that can overtake flower beds, and the types of weeds vary from region to region.

If you have identified a specific weed, then look for products that target it specifically rather than trusting all-purpose weed killers. Some of them might damage the weed but not enough to keep it at bay for long. For general weed problems, make sure you apply the product to the weeds only and do so on a calm day (no wind or breeze).

In the Yard

You usually combat clover, dandelions, chickweed and other types of invasive grasses like Annual Bluegrass or Crabgrass. Look for products that target one or several of these if you want to eliminate them.

The same products used for lawns are also great for use on walkways, patios, and some flower beds. They must always be applied safely.

In the Vegetable Garden

Anytime that food is involved, you need to be careful about what you are applying to the weeds. Here is where manual weed removal will always be the best first option.

When looking for a killing product, we suggest you start with natural weed killers such as boiling water. Dump boiling water can immediately kill many weeds. Another natural killer is a mixture of vinegar and dish soap that you can spray directly onto the weeds.

Weed prevention is the best way to help keep your vegetable garden happy. If you’re reading this in time, invest in some weed barrier fabric and apply it early on in the planting season.

If the patch of earth that you want to use for your vegetable garden is currently covered in weeds, you could go the chemical route and use a product that contains glyphosate. This herbicide is non-selective, meaning that it isn’t a weed-specific herbicide. Rather it will kill most living grasses and broad-leafed plants. You should do this well in advance (before planting vegetables). Otherwise, you risk killing seeds, seedlings, and plants by planting too soon. Just follow the instructions on the bottle and research how to use it before you go spraying and tilling.

Weed and Feed

When it comes to ridding your lawn of weeds, you might be better off purchasing a weed and feed that is specially formulated with two chemical agents. One is there to help kill weeds such as dandelions and clover while the other will feed your lawn.

These work great for lawns that have a bad case of weeds and are even safe in flower beds. If you’re just targeting a few weeds now and then, you can get by with a specialty spray to attack them specifically.

Top 5 Best Weed Killer Reviews

1. Round Up Pro Concentrate Systemic Herbicide 

Roundup Pro’s highly concentrated glyphosate mixture is the type of product that you would use to eliminate large patches of weeds. As we mentioned earlier, the glyphosate targets all grasses and broadleaf plants, so you shouldn’t use this on your lawn, or anywhere that you have healthy plants around that you would like to keep.

Round Up Pro Concentrate 50.2% Glyphosate 2.5 Gallon Jug Systemic Herbicide
  • Glyphosate 50.2%
  • Round Up Pro is used in many situations from agricultural farming to industrial vegetation management. It can also be used around residential homes and commercial businesses to control unwanted weeds. Roundup Pro is also used by many highway right of way (ROW) management companies, cities, counties, and municipal governments.
  • The Round Up Pro mix rate is 1-10.5 ounces per gallon of water depending on target weed. When mixing roundup pro make sure to use only clean stainless steel or plastic sprayers

It’s great in areas that have been overtaken by weeds, such as ditches and fields, and if you mix it up and use it in the sprayer, it works great at killing weed between stones, bricks and other crevices.

We realize that it is a bit pricey and not the most natural solution out there. But if you have solid weed patches that you would like to kill, then this is the best weed killer you can get your hands on.

Due to the nature of the chemical, this product cannot be purchased by those residing in Hawaii, Alaska or California. ✔️ Let's get it NOW! 

2. Eco Clean Pure 20% Vinegar 

This isn’t your regular vinegar that you use in the kitchen or your DIY cleaner spray. It is a strong, 20% solution of distilled white vinegar that you can use to attack weeds safely in your vegetable garden. You can actually use it for cooking and around the home. We buy this for gardening since it is more expensive than regular vinegar.

  • SAFE TO USE AROUND THE HOME — Unlike bleach, vinegar is naturally non-toxic, biodegradable, & non-caustic. Contains no dyes or chemicals.

One of the main reasons that gardeners use it is that it is environmentally friendly and natural, which means that applying it around the vegetables is in no way toxic or hazardous.

Before using vinegar on the weeds, you need to understand that it can lower the pH of the soil in the areas where you apply it. If you have alkaline soil, then adding a bit of vinegar is useful. Otherwise, it’s not helpful if you have acidic soil.

You should do some soil testing before using this and please, please make sure you wear safety gear when using this. It is an acid, and it can burn you at this high concentration.

*Price from:  2021-06-10 at 00:48 EST

Our final suggestion is a broadleaf weed killer. It will no indiscriminately kill all your plants. This one is selective and only kills certain broadleaf weeds.

Many use this on large, grassy areas such as cemeteries, golf courses, parks, and in ditches to give you an idea. The active ingredient is dimethylamine salt. This is an organic compound that won’t harm certain types of grasses, cereals, or turf.

Before you use this, it is important that you understand why species of grass or other plants will also be coated with it. If you don’t know and spray it on the wrong types, you’ll end up killing everything.

When used properly, it is a very effective weed killer. ✔️ Let's get it NOW!
