Weeds are time consuming to pull and seem to take over an area more quickly than you can react. If you prefer to take the easier way out, there are many herbicides on the market that will help take care of your problem. If cost is an issue, you can gather a few household items to make an inexpensive weed killer or deterrent.
Patios and Driveways
Clean out a spray bottle and fill it with vinegar. Vinegar removes the wax cover from weeds and dries them out all the way down to the root. Use a stronger concentration of vinegar than you can buy in grocery stores, which is typically 5 percent.
Add a few drops of liquid dish soap. This makes the vinegar and other ingredients stick to the area you spray and keeps it from easily washing away.
Add a few tablespoons of salt to the spray bottle and put the lid on. Shake the bottle to mix it and help dissolve the salt. The salt is the key. It will make the soil uninhabitable for an extended period, preventing new weeds from growing.
Spray the weeds, taking care not to get the mixture on anything you want to live.
Where Plants Grow
Sprinkle a mix of chili pepper and sugar directly on the weeds. The pepper will keep insects away from the sugar. The sugar feeds the micro-organisms in the soil and sends plants on a feeding frenzy as they rapidly grow. This temporarily takes up the nutrients in the surrounding soil, including nitrate, causing the soil to be uninhabitable for a time. The end result is a dead weed as well as anything else in the same area. For this reason, pour sugar directly on the weed so it doesn't hurt other nearby plants.
Put cornmeal into a fertilizer spreader. Gluten cornmeal is best, but others will work. Cornmeal keeps weeds from germinating, preventing them from growing in the first place.
Spread the cornmeal around the lawn and plant areas to keep weeds at bay.
