What is one of the biggest challenges when working with chemicals in your garden? Rain of course. You don’t want all the important particles to wash away before they even started working.

If you’re living in a high rainfall area, this concentrate should be on your shopping list. It’s rainproof within two hours, so you have minimal risk of losing out on its effects. The weeds will disappear thanks to the high concentrate—41%-of glyphosate.

But take note, this weed killer kills everything. Don’t put it on your grass if you still want it. However, it’s ideal for clearing weeds from walkways and can be added in between vegetables to kill weeds, as long as it’s not on the plants themselves.

But here’s what’s amazing about this weed killer and one of the reasons why it’s our top choice. It will kill everything today, but 24hours into the future, you can start planting new flora again.

Here’s a favorite of many gardeners and for us, it was one of the best weed killers for lawns. What are your most important requirements of a weed killer? Roundup is well known because this super concentrate performs well in many areas:

  • It’s rainproof within half an hour
  • Weeds wilt quickly
  • You get 85 gallons from a one-gallon canister

This weed killer works by entering the plant through the leaves. This will channel the glyphosate to the roots. The entire plant will be affected and die as a result. You’ll see them completely dead at the end of two weeks.

With 50.2% of the substance being glyphosate and isopropylamine salt, you can be sure it’s one of the strongest weed killers mentioned in these reviews.

  • Support: The brand provides supporting gear such as sprayers and the product comes in a variety of sizes.
  • Fast acting: The first effects will be seen within 12 hours.


  • Dangerous: You can’t use this in the vicinity of edible plants such as your vegetables.

Weed Killers Buying Guide

So how do you know which one to pick?

No, there is no one perfect weed killer, because each garden is different. If you want the perfect solution, you must first analyze your problem. Then we’ll find the ideal product that matches your specifications. So before you go to the store to buy a herbicide, here are a few things to keep in mind.


What is your goal? Weeds may be a general term for you, but if you want to find a high-quality weed killer, you need to know what you’re up against.

Certain herbicides are designed to kill off a specific type of plant, such as:

  • Broadleaved weeds
  • Grasses
  • Sedges

Write down what your challenge is and search for appropriate products. Will the herbicide you consider also kill off your grass? If you don’t want this to happen, look for grass-friendly weed killers. Alternatively, you’ll only be able to use the product on gravel or stone areas.


Don’t think the most expensive weed killer will be the best. The product that will rid you of a specific weed may be the cheapest one on the market.

But if you find expensive top-rated weed and grass killers, it’s worth investing in it. Cheaper versions may be less effective. This may require multiple applications or they may never work. This means you’ll spend as much as you do on the expensive products, without getting the effect you want.

And don’t forget you can cost yourself a lot of money if you buy cheap weed killers that state they will help your grass, but end up killing it. Then you’ll spend your money on building your garden from scratch.

Can you see why it’s important to purchase the right item and not simply follow the advice your neighbors broadcast? Each situation is unique.


Fast Action
How quickly do you need to see effects? This isn’t the most important feature, as usual, it’s simply necessary that the weeds eventually disappear. But in some circumstances, this may be a deciding factor. Do you need your garden to be ready for an upcoming event? Luckily the fastest products kill weeds within days.

How long must you wait before you know the particles are attached to the plants and won’t wash away? It’s called rainproof and this is important if you want to plan to water your garden. And if it rains soon after you applied the product, you may need to add another application, as the chemicals may have washed away.

Long Effect
The other important timeline is how long it will keep weeds at bay. It doesn’t make sense using a substance and seeing weeds return within weeks. Few products can promise to keep your weeds away forever, as the substance eventually disappears from the soil. However, there are herbicides that work for months on end. If you need to keep maintenance or labor costs low, this can be one of your important requirements.

Economical Value

Marketing can be misleading. Is it really wise to purchase the less expensive weed killer if you need to keep to a budget? Not if the concentrate won’t cover a large part of your garden.

I advise you to go to the store with a calculator and compare the different products’ economical values. Usually the packaging mentions:

  • How concentrated the mixture must be
  • How big an area the concentrate will effectively treat

Now in a comparison, find the most economical one for your large areas. If the cheap product can only treat a very small area, your final expense will be extremely high.


Of course, good herbicides contain dangerous ingredients. After all, something is supposed to kill the weeds.

But what organisms will find the particles dangerous?

  • Is it safe to use around your home where kids play?
  • Can you use it on edible plants such as your fruit trees?

Use these guidelines to decide whether you want to risk using it, or rather try a less dangerous option.

Usage Requirements

Gardening can be fun, but not everyone loves mixing liquids. If this is you, why not consider popular products that make it easier? It will save you time and effort if you pick a weed killer that is already mixed & has a nozzle that sprays.

Luckily for you – as can be seen in this review – good herbicide manufacturers cater for everyone in the market, even you.
