Things You'll Need

  • 2 tbsp. chlorine bleach

  • 1 cup water

  • Plastic spray bottle

Tip

As an alternative to mixing bleach solution, home pool owners can use granulated chlorine with similar results. Simply sprinkle 1/4 cup chlorine around the base of the weed and then add water. The water will dissolve the crystals and carry the chlorine to the roots.

Warning

Use caution when working with chlorine bleach. Protective gear such as rubber gloves and safety goggles can be used to prevent unwanted exposure to bleach solution. Should the skin or eyes accidentally come into contact with bleach, flush the affected area immediately with water. In addition, be sure to wear old clothing, as bleach will remove dye from fabric, creating unsightly white spots.

Any plant that grows where it isn't wanted is considered a weed. Gardeners spend countless hours toiling relentlessly in an effort to rid their yard of weeds. Chemical herbicides make the chore easier, but they can be expensive and dangerous to use. A simple, reliable weedkiller can be made from common chlorine bleach. Popular as a laundry aid, bleach is known for its ability to whiten and brighten clothing. However, the chlorine contained within the bleach is toxic to plant life. Direct contact with bleach chemically burns the plant's roots, causing dehydration of the tissues and the eventual death of the plant.

Step 1

Combine 2 tbsp. of chlorine bleach and 1 cup of water. Mix until the two are thoroughly combined, and then transfer the solution to a plastic spray bottle.

Step 2

Hold the spray bottle 8 to 12 inches from the unwanted plant. Spray the plant with the bleach water, being sure to completely cover the foliage. If other plants accidentally come into contact with the bleach water solution, rinse them immediately with copious amounts of cool water.

Step 3

Inspect the plant each day. If after three days the vegetation shows no signs of deterioration, reapply the bleach water.

Step 4

Store any unused bleach water solution in a cool location. Label the bottle clearly to avoid unintentional mix-ups.
