Homemade Weed Killers and Methods


One of the most popular home concoctions for a weed killer is vinegar. Vinegar is a very effective weed-killer. Combine it with salt and you’ve got yourself a homemade weed-killer. This method works well because white vinegar kills weeds by dissolving the cell walls of plants. Salt helps the solution penetrate deeper into the plant tissue. This solution is also fast acting so you should see results in just a day or two.

If you have an old spray bottle you can simply mix up the solution in it and then spray the grass or weeds you want to kill. Just mix 3 parts water to 2 parts white vinegar and add a few tablespoons of salt. Spray the mixture onto the weeds and leave it alone. After 15 minutes or so you’ll want to rinse the area where you sprayed the solution so it doesn’t damage patio pavers.

While this homemade weed killer will work great it’s only a short term solution. The roots of the weeds and grass will likely remain alive and grow back every few weeks. While it’s not much of a hassle to spray your patio every few weeks it can be tiresome after a while.

Baking Soda

To control weeds around your house you can sprinkle baking soda on the area where weeds are growing in the cracks of the patio pavers.

You may have to pull the dead weeds from the ground being careful not to disturb the pavers around the weeds.

To apply simply sprinkle the baking soda around the roots of the weeds or in the case of a paver patio into the cracks between the pavers. Putting the baking soda on leaves can work but it works better when it dissolves and soaked up by plant roots.

Baking soda is also relatively cheap and available at most grocery stores so it’s easily attainable.

Boiling Water

Weeds can be quite annoying and tend to take over our lawns, gardens, and yards. They can be hardy plants that grow quickly, are very competitive, and reproduce rapidly.

One way to deal with weeds and kill them naturally is to use boiling hot water.

Just pour boiling water on the weeds to kill them. While this method can work it is extremely dangerous. If you plan to use this method make sure you do so safely.

Dry Salt

A simple application of salt can help you keep unwanted plants under control. This method works best for small patches of weeds where it is easy to apply the salt directly to the soil such as in the cracks of your patio. You can use salt to kill weeds and prevent new growth. Be careful when letting salt sit on brick patio pavers however as they may damage or discolor the patio pavers.

One problem with using a high pressure washer however is that it can blast the sand that should be between the pavers away. Over time you may even take out too much of the sand and the pavers will start to sink into the base layer causing them to become uneven.
