A lush, gorgeous, green lawn is the envy of the neighborhood. But when weeds crop up, whether clovers, dandelions, or crabgrass, that beautiful lawn becomes a hassle, and far less appealing.
So, when it’s time to get rid of those weeds, you need a good herbicide. But to know which herbicides you need, you’ll want to do a little research.
If you’re trying to get dandelions, we’ve already done the basics for you and provided a breakdown of types of herbicides and a buyer’s guide to help you choose the best option possible for your lawn and garden situation.
Editor’s Pick: Dandelion Killer
How To Get Rid of Dandelions
There are a few different methods for getting rid of dandelions, but the main one that’s most effective is using a chemical herbicide.
Ideally, for dandelions, you’re looking for an herbicide that focuses on broadleaf weeds. These systematic dandelion killers are usually made with glyphosate and should be applied directly to the weeds you’re trying to knock out. Avoid applying these to the whole lawn, however, as they may harm the grass you want to keep.
This kind of weed killer is applied directly to the leaves of the dandelion and kills the vegetation through the death of the greens. After the greens die, the chemical seeps down into the plant and roots and kills the whole plant completely.
How To Choose The Right Weed Killer
Since some of the chemical herbicides are so dangerous for your lawn, you’ll want to make sure you’re getting the right kind for your own needs, where you might need to have a broader application.
There are four basic types of weed killers. They each approach weed killing in a different way and can be applied to different kinds of plants, based on the particular season, plant type, and/or circumstances surrounding the weed issue.
Emergent Weed Killers
Selective Weed Killers
Persistence Vs. Non-Persistent
Translocated Weed Killing
