Get a gallon sprayer at a Home Improvement store. Mix equal parts
of vinegar and lemon juice in the sprayer and spray directly on the weeds. It
works best if the temp stays above 70 degrees at least for a couple of days.
Watch the weeds turn brown and die in no time! Repeat as needed!
Mix 1 gallon white vinegar, 1 cup table salt, and 1 tablespoon
dishwashing liquid together and spray on weeds. To do so, remove approximately
2 cups of vinegar from the jug, pour in the salt and dishwashing liquid, then
return the 2 cups of vinegar to the jug. Close the lid and shake to mix.
Here's a great weed killer you can make yourself for about $2 a
gallon: Dissolve 1 pound table salt in 1 gallon white vinegar (5% acidity is
ideal) Add 8 drops of liquid dish washing detergent (helps plant material
absorb the liquid) Label and keep out of reach of children. You can use this in
an ordinary spray bottle. This non-toxic formula acts as a temporary soil
sterilizer, so don't spray near roots of trees, shrubs, or plants you'd like to
keep. This is especially effective on a gravel driveway.
1 gallon white vinegar plus 1 pound of table salt
Here's something I've used: Combine one ounce gin, one ounce dish
soap and one ounce vinegar. Put into a 32 oz. sprayer and fill with water.
Spray just the weed.
You can also put baking soda on just the weed. They turn black
and shrivel up.
To kill weeds in sidewalk cracks, pour boiling water on them.
If you go purchase vinegar, 10% acidity, 20% acid would be
better, and spray it on the weeds in the heat of the full sun, you will have an
effective weed killer.
