Do You Want to Just Kill Dandelions or Other Plants Too?

When choosing the best dandelion killer for your yard, you need to have a firm grasp of what your needs are. Do you want to kill the dandelions only or do you have other plants you would like to eliminate as well?

  • Selective Herbicide. If you just have a problem with dandelions and you want your other plants to remain healthy, you need to look for a selective herbicide. A selective herbicide is a substance that will get rid of weeds like dandelions without harming the other plants in your yard that are actually wanted.
  • Non-Selective Herbicide. If you have dandelions popping up through the cracks in your sidewalk or patches in your driveway where you don’t want any plants at all, you should opt for a non-selective herbicide. These will kill almost every plant it comes in contact with, including dandelions.

You Might Need Both Nonselective and Selective Herbicides

Most yards have more than one type of surface. You have your lawn, but you’ll also have driveways, patios, and flower beds.

  • If you’re having problems with dandelions in your yard, but also on the cracks in your driveway, you should bite the bullet and buy both types of herbicide. A selective and a nonselective. They both address the specific needs of your lawn.
  • You might not welcome the expense of purchasing two types, but your situation demands it. If you’ve spent so much money buying a house and maintaining it, you don’t want to get cheap. The solution is pretty quick and simple and results in a better appearance.
  • Getting rid of the grass, dandelions, and other weeds that are poking through cracks in sidewalks and driveways will help your yard have a tidier, well-maintained look.

What Kind of Herbicide Will Take Care of Dandelions?

Dandelions are classified as a broadleaf weed. That means you need an herbicide specially formulated to kill off broadleaf weeds. The good news is that modern herbicides generally do quick work of broadleaf weeds if properly applied.

You can’t just mow dandelions and think that will take care of your problem. They must be killed at the root, not the stem.
