You may pick flowers from your garden to decorate your table with, or you may purchase them from a florist. Either way, you will want to keep your flowers in a vase. You can keep your flowers fresh much longer in a vase by adding water and a few ingredients found in your household. These ingredients will feed the plant and kill any bacteria that would cause the flowers to wither away at a quicker rate.
Hold the stems of your flowers in a bowl of lukewarm water. Cut off an inch of the stem under the water with gardening scissors. Make sure you cut the stems at an angle.
Fill your vase with one quart of lukewarm water.
Add 3 tbsp. sugar and 2 tbsp. vinegar to the water in the vase. Combine the ingredients. The sugar works to feed the plant, while the vinegar keeps bacteria from growing and destroying the flowers.
Transfer your flowers from the bowl to the vase.
Change the water in your vase every three days.
