If you’re wondering how to get rid of the weeds in your flower bed or lawns, you’re not alone!
You can get about it the ordinary way by hand plucking the weeds but this is laborious and not a permanent solution.
The weeds will just grow right back if not removed by the root. We believe that the best way to deal with it is by applying a weed killer or a herbicide.
Pre-emergent weed killers can be applied before planting the flower seeds but there are post-emergent killers too if you spotted the weeds late.

Guide to Buying a Weed Killer for Flower Beds
To help you decide which weed killer would work best for flower beds, here are some factors to think about.
To be able to choose the right product, it’s essential to also find out the ingredient that is used. Below is the list of the most popular ingredients found in weed killers:
- Glyphosate: An agro-chemical, this is the most common ingredient used in mass-manufactured products.
- Boric acid, Borax, and Borates: Easily available, these chemicals are often used for DIY.
- Corn Gluten Meal: This is not very heavy duty and works for common, less-aggressive weeds.
- Clopyralid: This is most commonly used to deal with broad-leaved weeds.
- Diuron: A heavy-duty herbicide, this requires careful handling.
- Natural: In recent times, we can find gentler and environmental methods like vinegar and soap being used
2. Methods of chemical treatment:
There are two primary methods of dealing with weeds such as:
Pre-emergent Weed killer:
- There are a lot of weed killers out there and some of them are designed for killing the problematic weeds. But we recommend taking care of weeds before they’ve popped up. For that, you’ll need a pre-emergent weed killer which is a protective barrier to prevent weeds from sprouting.
- It stops the seeds of the weed from germinating and if they have sprouted, it will stop them from taking root. Such products are best used in the edges of paths, fences, and other hard surfaces.
Post-emergent Weed Killer:
- Post-emergent weed killers work after the weeds have germinated and broken the ground. The advantage is that you wouldn’t have to hand pluck the weeds from the ground.
- Now be very careful with choosing a selective or non-selective weed killer. A selective weed killer will not damage any other plant/flower beside the weeds while a non-selective will damage anything it comes in contact with. Choose a non-selective weed killer only if your flower bed is rampant with weeds.
Pesky weeds can ruin your hard work of growing and maintenance a flower bed. But with so many options out there, it can be difficult to choose the best weed killer that suits your requirements.
That is why this in-depth review has been made after a lot of research and testing a wide range of products so that you can find something that will definitely work.
