Things You'll Need

  • 1 gallon white vinegar

  • 1 12 ounce bottle lemon juice

  • 1 cup salt

  • Large pot

  • Spray bottle or gallon jugs

Tip

Use a spray bottle with an adjustable nozzle so that you can focus the spray directly on the offending plants. If your patio is nowhere near plants that you don't want to kill, mix salt in with sand and sweep it into the cracks between the patio pavers to prevent seeds from taking root.

Warning

Be careful not to get the mixture on plants that you want to preserve, because the lemon juice, salt and vinegar is a nonspecific natural herbicide.

Keep your brick patio free of weeds with a natural weed killer.

Weeds growing between the cracks of a brick patio can be a challenge for even the most determined landscaper. No matter how well you tamped down the gravel and sand, you will end up with weeds and grass growing in the cracks between the bricks. Pulling them by hand is time consuming and backbreaking. Chemical herbicides can harm the environment and poison your pet. But there is an easy way to kill grass between patio bricks that's completely natural and easy to use.

Step 1

Mix 12 ounces of lemon juice, 1 gallon of vinegar and 1 cup of salt in a large pot over low heat, stirring until the salt is dissolved. Allow the mixture to cool. At this point, you can set the mixture aside until you are ready to apply it to the weeds between the patio bricks. It will keep for weeks in a covered jar in a cool, dark place.

Step 2

Fill a spray bottle or gallon jug with the vinegar mixture. Choose a hot, sunny day to apply the lemon juice, vinegar and salt to the weeds and grass between the patio bricks. Spray the foliage well, then pour the remainder into the soil around the plants' roots.

Step 3

Wait a day, then reapply if necessary. The plants will wilt and dry out so that they can easily be raked up and disposed of.

Step 4

Repeat the treatment when necessary, or seal the sand between the bricks with a polymer based sand to prevent the weeds from rooting again.
