I researched Glyphosate to better understand its use and I’ve found out that it’s been used for over 40 years as a safe and cost-effective weed control!

Weeds are evil. They can grow faster and grow bigger than your typical garden-variety flowers and plants. Because of this, they compete with your flowers and plants over sunlight and nutrients from the soil⁠—making your flowers and other plants unhealthy and malnourished.

Some users have also pointed out that the formula is so strong that it could hurt other plants in the garden. So you really have to be careful with the application.

I also read a lot of reviews from genuine users of the products and one of the points frequently reiterated is that applying a mix with higher Glyphosate in your flower beds or gardens do not necessarily make it more effective.

Glyphosate works in such a unique way that you only need to use the recommended strength and it’s fine that way. To use the product, spray on a dry day, early in the morning⁠—and ideally when it’s not WINDY. It may spray on to the other plants and can affect their growth or even kill them.

The Most Common Flower Bed Weeds

Here’s a list of the most common weeds you might find in your flower beds. Most of these can be controlled by the weed killers mentioned above:

  • Crabgrass

One of the most common grass weeds you can find in flower beds is the crab grass⁠—notorious for its resilience and quick growth (because it can grow as tall as 2 feet). Crab grasses are easy to manage as long as you get their seeds under control because their seeds can remain viable for up to 3 years underground.

Pre-emergent herbicides can be useful in preventing crabgrass from germinating. If crabgrass has already started growing, it is advised to use post-emergent herbicides.

  • Pigweed (Amaranth)

Pigweed is also a common weed that pesters almost every garden known (and unknown) to man. It multiplies in gardens through its seeds, that’s why it’s advised to take out the plant before it flowers and spread out its seeds.

Its leaves are edible (and even healthy!) but because of its ability to absorb nutrients fast from the soil, it can outcompete your flowers and make them unhealthy and malnourished, so it’s better to remove them from your flower beds.

  • Field Bindweed (Perennial Morning Glory)

Commonly associated with the annual morning glory, the field bindweed is the “ugly” version of the former and has thinner stem and smaller flowers. Field Bindweed is an invasive species, which means it is resilient and can easily adapt to different environments.

It can also root up to 14 feet deep, making it one of the hardest plants to completely remove on this list. A single field bindweed plant can spread more than 10 feet!

Luckily, field bindweed can be easily managed with pre-emergent herbicides (and early intervention⁠—removing them while they are still seedlings help control the plants reproduction).

  • Dandelions

Dandelions are a familiar plant. Their bright yellow flowers provide a good source of nectar and pollen for bees. Despite their beauty, dandelions can ruin flower beds. Their strong roots can cut deep into the soil and absorb its nutrients, making it harder for your other flower plants to compete.

What’s worse, completely removing dandelions is a complicated task. Any piece of their roots remaining in the soil can help them grow back. So it’s best to use strong herbicides to prevent them from growing.

  • Lambsquarters

Lambsquarters are categorized as the most common weed in gardens according to Weed Science Society of America (WSSA). They are a fast-growing annual and can quickly reproduce through their light seeds that can travel distances when blown by the wind.

Lambsquarters can quickly absorb water and nutrients from the soil, so it is important to remove them as soon as you notice them growing in your garden. Fortunately, a lot of post-emergent herbicides can swiftly take care of them.

  • Chickweed

Chickweeds are primarily categorized into common chickweed and sticky chickweed, with the former commonly found in flower beds and gardens. Both are pesky weeds that compete with other plants for nutrients and sunlight. They can produce up to 800 seeds and can take 7 to 8 years to be eradicated.

Chickweeds can easily be managed with pre-emergent and post-emergent herbicides, along with other preventive techniques such as organic mulching.

  • Quackgrass

Quackgrasses are persistent weeds that can easily spread in your garden. It looks similar to crabgrass but its long tapered blades are thicker compared to the latter. Quackgrass quickly reproduces through its seeds⁠—usually when moved by birds or blown by wind.

It is hard to manage but it can easily be controlled with pre-emergent (controlling them before they grow) and post-emergent (killing them after they’ve grown) herbicides.

With all this information about weed killers and different varieties of weeds, it might be difficult for you to choose the best weed killer that fits your needs. So let me break down the factors that you should look for when choosing a weed killer.

Factors To Consider When Choosing A Weed Killer For Your Flower Bed

These are the most important factors to consider when buying the best weed killer for flower beds:

  • Kind of Weeds You are Treating

Weeds differ in resilience and response to the treatment they receive. That’s why it’s important to consider identifying the weeds that you’re intent on removing. This will help you understand the next steps you should take⁠—including choosing a weed killer’s brand and formula.

Some weed killers are designed only to prevent seeds from germinating, while others can kill weeds that have fully matured.

  • Formula Of The Weed Killer

Different brands have different formulation. Most herbicides contain Glyphosate, which is a controversial ingredient notorious for its association with cancer. Not enough research has been done to prove this though so take this with a grain of salt.

The formulation can also spell out the effectiveness of the product in removing your garden-variety weeds. So make sure you know the brand’s active ingredients before making a purchase.

  • Mixture Or Solution

Some weed killers are pre-mixed, meaning they’re ready to use. Most herbicides, however, have suggested ratios when mixing their products with water. Be careful in making your mixture or solution too concentrated or too diluted.

Diluted solutions may weaken the product’s effectiveness while concentrated solutions may be too strong for the soil that it kills desired plants nearby.

  • Weather And Season

Although some herbicides are designed to withstand the rain, most herbicides take full effect during the dry and sunny season. So take the weather into consideration when buying the weed killer of your choice. Make sure that what you’re getting can withstand the weather in your area.

If it’s sunny and dry all throughout, picking a brand won’t be much of a problem.

  • Replanting Period

If you wish to replant or reseed or lay a sod in an area treated with herbicides, consider the period recommended by the brand of your choice. Some herbicides are so potent that it may take a while (like more than 3 weeks) for you to replant in the treated area. Others are not so potent that you can replant in the same weekend.

  • Value For Money

Value for money means the product that you should consider is reasonably priced, effective, and is fit for the demands of your flower bed. Some products are way too expensive compared to other brands that can perform equally. Others may be too expensive for the size of your garden or for the type of weeds you are experiencing.

That’s why you should ask yourself if the product you’re getting is worth the dime.

  • Pre-emergence vs Post-emergence

Herbicides are categorized into pre-emergence (which means they should be used before the seeds fully germinated) and post-emergence (used when the plant matured). Some products are designed to be pre-emergent while others are post-emergent. Identify the needs of your garden and take this factor into account.

But which one is better for your garden? Is it the pre-emergent herbicide or the post-emergent one?

Pre-Emergence vs Post-Emergence Herbicide: A Closer Look

Pre-emergence herbicide is great for weed prevention. They are designed to stop seeds from germinating and they are often formulated to be gentle with fully matured plants. Some products can even be applied near vegetables and fruit-bearing plants⁠—making them safer than post-emergence herbicides.

Pre-emergence herbicides can help reduce the need of maintaining flower beds as they can inhibit the growth of most weeds when applied. Some products even claim to have this effect up to 1 year⁠—which is highly convenient for those who find it tedious to manually pluck out weeds in their flower beds.

Post-emergence herbicides are those suited to kill mature weeds⁠—weeds that have fully germinated and grown. They are usually formulated to be potent which requires you to protect desired plants with hard materials like plastic and cardboard. While post-emergence herbicides may prevent the growth of seeds, pre-emergence herbicides are weak enough to kill mature weeds.

You can choose to have both for a guaranteed weed-free flower bed. But if you just want to choose one, it all boils down to the gravity of the weed problem you are having. If it’s too much, choose post-emergence herbicides. If it’s not too serious, then pre-emergence herbicides may work fine.


I hope this list has helped clear up any confusion you might have had on the broad topic of pesticides! By now, you should be familiar with all the top herbicides on the market, and you should be ready to go off and do your own research.

All 10 of the pesticides above are known to be effective and reliable! Keep in mind, that some of the brands may be a bit of an overkill and some may be too weak for your weed problem. What works for your neighbors garden won’t necessarily work for you—at the end of the day it’s about finding a product that works for your needs.

I wish you the best of luck, and a weed-free garden!
