How to Bleach Amaranthus Flowers

Amaranthus plants produce dark red or green flowers. The flowers bloom on erect stalks that can sometimes drape over the plant toward the ground. These flowers are common in arrangements. Using bleach on amaranthus flowers will make them last longer in cut flower arrangements. The bleach kills germs growing in the water used for the arrangement, and it also helps keep the water looking clear when you add plant food.

Instructions

- 1
  Fill the flower vase for the amaranthus with one part lemon-lime soda and three parts water. Pour in 1/4 tsp. of bleach foe every quart of the soda-water solution.

  Fill the sink with water. Submerge the stems of your cut amaranthus in the water. Recut the stems at a 45-degree angle. This prevents air from getting into the flower stems and blocking their upward pull of water.

  Lower the stems into the vase with the soda-water and bleach solution. Add 1/4 tsp. of bleach to the flowers every four days to keep the water fresh.
