Clean a vase with hot water and soap to remove any bacteria that could harm your tulips. Rinse well.
Fill the vase with lukewarm water and add a pack of flower nutrients, which can be obtained from a floral shop or grocery store which sells flowers.
Clip 1 inch from the bottom of the stem diagonally and remove the leaves from the bottom of the stem so they will not be in the vase.
Place the blooming tulips in an area in your home away from direct sunlight. They need a cool area in your home to prolong the life of the blooms.
Cut the stems 1 inch every three to four days and change the water at the same time. Add another flower nutrient pack, mixing well, before placing the tulips back into the water.
