For those who want to keep their home gardens lush, the best weed killers for flower beds are all pre-mixed herbicides, but choosing the right one comes down to a surprising number of factors: selective or non-selective; pre-emergent versus post-emergent; and chemical as opposed to organic. Since these options depend greatly on your situation — and the types of weeds you want to eliminate— I’ve rounded up the best from every category.
First, here are the key things to consider when shopping:
Selective Vs. Non-Selective
One of the challenges of using herbicides in gardens is that weeds may be growing side-by-side with your beloved flowers. For that reason, you may first want to try a "selective" formula, which will eliminate certain types of weeds or grasses while sparing your ornamentals from damage. If you want immediate, fast-acting control, however, a "non-selective" herbicide — which kills everything it touches— can still be used near flowers, you'll just want to look for one with a targeted spray nozzle so you can zero in on bothersome weeds.
Pre-Emergent Vs. Post-Emergent
Most weed killers are designed to eliminate "post-emergent" weeds that have already come to the surface. But if you time it right, using a "pre-emergent" version can save you trouble by preventing weeds before they sprout. The catch is that some of the pre-emergent herbicides need to be applied in late spring, which is the climate when weeds typically begin to germinate.
Weed Killer Safety & Precautions
You'll notice that weed-controllers typically include chemicals as their main ingredient (glyphosate is the most common) because they are the most effective. However, if the uncertainty surrounding potential health risks of a chemical herbicide makes you uneasy, you can instead opt for an organic, vinegar-based option, just note that most are non-selective.
And no matter which type you choose, you should take precautions when applying: Wear goggles, gloves, and protective clothing to limit exposure. And check the label before spraying anywhere where pets and children may linger.
