Baking soda is the key ingredient to killing unwanted weeds from any cracks in your your sidewalk or driveway. It's the same ingredient you use when baking cookies, so you don't have to run out of your house and buy something new. Baking soda is sodium bicarbonate, which is phytotoxic to plants.
Usually, on average, it takes about three to four days for soda to completely kill all weeds after just one application of a potent mixture. You can tell weeds die when they turn yellow and brown or black after a few days of a baking soda spray.
Just dissolve 1 ½ cup of baking soda and a tablespoon or two of vinegar in a gallon of water. Transfer the concoction in a spray bottle and spritz away! This solution works better as a preventive treatment so spray away on areas that are prone to weeds at weekly intervals for best results.
The most effective homemade option is a mixture of white vinegar, salt, and liquid dish soap. Each of these ingredients has special properties that combine to kill weeds. Both the salt and the vinegar contain acetic acid, which serves to dry out and kill the plants.
Sprinkle baking soda on your soil with a flour sifter to keep ants, roaches and slugs away from your garden. (Be sure to avoid your plants!) It's a safe way to keep beneficial insects around and say sayonara to the ones you're tired of seeing.
If you have ant mounds outside, dampen the mound with water and then sprinkle about 2 cups of baking soda on it. Wait a half hour or so and pour a cup of vinegar on the mound. That combination will kill most ants. You can make a bait with half baking soda and half sugar to control ants and roaches.
Because it's household ammonia, it contains the right amount of nitrogen plants need. To make this homemade plant food: 1 1/2 tablespoons of Epsom salt. 1 teaspoon of baking soda.
Vinegar and salt will dry out weeds and grass, whereas the dish soap helps the vinegar and salt to cling to the leaves rather than absorbing the mixture. If utilized correctly, they may be an effective herbicide.
Rock salt is actually a super-effective and totally natural weed killer that is ace at clearing a gravel driveway. Simply sprinkle some rock salt on the ground surrounding any weeds you can see and then sit back and watch as the salt kills the weeds in just a matter of days. It's almost unbelievable.
The Takeaway. To eradicate weeds effectively, the roots need to be killed, not just the top growth, which synthetic weed killers do successfully. The bottom line is that mixing vinegar with Epsom salts or table salt and liquid dish soap does not make a safe, effective weed killer.
Acetic acid is a terrific weed killer but it is also a terrific plant killer! Acetic acid works by drawing all of the moisture out of the weed or plant leaf. It is quick to work and it would be common to see a weed or plant brown up after only a few hours of having vinegar applied to its leaves in the full sun.
Vinegar is acidic and will eventually kill most broadleaf weeds, but the acid will kill the leaves before reaching the root system, and the weeds may grow back quickly.
The researchers found that 5- and 10-percent concentrations killed the weeds during their first two weeks of life. Older plants required higher concentrations of vinegar to kill them. At the higher concentrations, vinegar had an 85- to 100-percent kill rate at all growth stages.
Technically, yes. But practically speaking, it's not ideal. Because high concentrations of sodium are toxic to plants, if you dump a bunch of dry baking soda onto a small plant, it will probably die. Also, because sodium is soluble, it's likely to hurt or kill nearby plants that you didn't want to harm.
Mix them together and spray on your plant's leaves twice a month as a preventative measure; or spray on the leaves every three days to treat an existing fungal problem.
Kill Weeds
Similar to vinegar, it is a food that has a lot of acid but can still be consumed. Since vinegar kills weeds, it's easy to see how Coke would kill weeds, too. Simply pour Coke on weeds in cracks on the driveway or patio. This is not a selective weed killer, though.
Lay a weed proof membrane or fabric foundation before laying the gravel. This will stop weeds from growing in your driveway and spreading their roots into it.
Glyphosate, the ingredient in Roundup and other products, is translocated from the leaves to the roots of a weed. Vinegar is not translocated. It is true that 5% vinegar (acetic acid) will kill young, tender weeds but it does little damage to established weeds.
There are pros and cons to both spraying and pulling weeds, and we have a good rule of thumb you can use when choosing a method. Hand-pulling is easier when you are focusing on a small area. Spraying weeds is ideal when you're dealing with a vast area or a loftier infestation of weeds.
White vinegar with an acetic acid content of at least 5% will be required to kill most weeds effectively. Apple cider vinegar with the same acid content will also work, though, for tough perennial weeds, you may need a specialised horticultural vinegar with 20% acetic acid.
Adding Epsom salts to soil that already has sufficient magnesium can actually harm your soil and plants, such as by inhibiting calcium uptake. Spraying Epsom salt solutions on plant leaves can cause leaf scorch. Excess magnesium can increase mineral contamination in water that percolates through soil.

Sprinkle full-strength baking soda on garden soil in paths and around plants where insects are an issue. The best way to apply the dust evenly and without over-application is by using a flour sifter. As a soil dust and repellant, baking soda is effective against ants, roaches, silverfish, slugs, and snails.
