Killing Weeds in a Patio

Killing weeds in a patio can be accomplished quickly and easily.

The following methods are non-selective, which means they will kill any plant they come into contact with. This includes grass and plants, which also often pop up between patio stones.

Just be careful around the edges of the patio so that you don't accidentally kill the bordering lawn or landscaping.




  1. Nonselective herbicide. Roundup is the most familiar brand name product. Its main ingredient is glyphosate. This is the choice of landscapers because it is quick and efficient.
  2. Boiling Water. Just pour boiling water onto your patio. It will kill all weeds, grass, and garden plants. This won't harm people, pets, or the environment---as long as you don't burn yourself in the process.
  3. Vinegar. This is acetic acid, a very effective weed killer. Whether you use the vinegar you have in the pantry or buy it at a garden center, the result is the same. Garden centers often contain weed control products that are a combination of vinegar and lemon juice, rather than straight vinegar.

Note: I do not recommend pulling weeds out by hand, unless there are very few. It's too cumbersome.

Killing weeds is never a one shot deal. Landscapers spray Roundup several times a year on patios, walkways, sidewalks, gravel driveways, and in plant beds. Nature is persistent. It will overtake your house if you neglect maintenance.

If you don’t have time to do it yourself, have a local lawn maintenance company do it. You can sign up online for a free estimate.
