Buyer’s Guide:

Now that you’ve got the best recommendations, you must be wondering about what factors to consider while buying the weed killer that satisfies all your needs. To help you with that, we made a curated list on what should be the major factors to consider before you make the purchase.

Unfortunately, purchasing a weed killer isn’t as simple as picking the first on the rack. Not if you need the best outcomes.

There are a wide range of types, and recognizing what they do will assist you with settling on the most ideal decision for your circumstance. Here are some significant factors to consider before you purchase:

  • Selectivity

Selectivity is the ability of weed killers to only get rid of the weeds and leave the plants unharmed.  

Selective weed executioners obliterate weeds yet not turfgrass or other useful plants in the region, making them a decent choice for destroying, for instance, dandelions or thorns on the grass or in a flower bed.

Non-selective weed executioners kill weeds alongside some other plants in the application territory. Use them along the fence or pool or in garage or walkway breaks, where you won’t put advantageous plants in danger.

  • Emergence

Emergence counts as the factor of growth of the weeds at which you must apply the weed killer.

Pre-emergent weed killers also known as “weed preventers” prevents weed from growing itself. They can’t be used to eradicate the already existing weeds.

Post-emergent weed killers also known as “herbicides” get rid of the weeds that have already grown, they can’t prevent new ones from growing but they kill the already grown ones.

  • Translocation

Translocation describes the movement of the product within a weed once it is taken up through the leaves, stems, or roots of the plant.

Contact weed killers don’t move within the weed once they enter it; rather, they kill the weed by destroying the plant part to which you apply them, usually within hours to days of application.

Selective weed killers move within the weed after they are absorbed, usually down to the roots, destroying the whole plant from the bottom up. You might have to wait several days or even weeks to see results, although unlike contact weed killers, systemic products generally won’t state the specific period of time it takes to kill weeds.

  • Persistence

Persistence is a measure of how long after application a weed killer remains in the soil and provides weed control before you have to reapply it.

Persistent or “residual” weed killers stay in the soil and keep new weeds from growing in the application area for months or even a year after application. They’re a good option for lawns or gardens where you need lasting weed control, but they can also inhibit the germination of new plants you grow in the area for a longer period of time.

Non-persistent or “temporary” weed killers degrade in soil within a few days to weeks, which forces you to reapply the product often to keep weeds at bay but allows you to quickly replant other plants in the area without interrupting their growth. This makes them a better option for gardens where you intend to plant flowers or vegetables in the near future.


Despite there being a lot of weed killers in the market now, it’s not feasible to come up with the best one as it really depends on your situation. Keep in mind the types of weed you are dealing with and how you want to attack it and what way works out the most for your flower bed without harming it in any sort of way.

The best part is there are a lot of great options out there to consider before you make the purchase. If you want something that works swiftly and don’t mind using harsh chemicals or if you are looking for a safe weed killer for flower beds that’s certified organic, there’s a weed killer for you.

If you’re having trouble keeping weeds away for good, try not to get disheartened. This happens with everyone and takes time to figure the right thing out. Make sure you’re using the right weed killer for the specific weeds you’re dealing with and don’t forget to mulch.

Sometimes a combination pre-emergent and post-emergence approach might be what you need to eliminate weeds for good. To get you covered on that too, we have included a little bit of everything on this list to help make sure you have all your bases covered. You can trust everything on this list and go ahead with what you think is the most suitable for you.
