How do you  make cut tupis last longer?
<answer> Start with a very clean vase. Fill it about 1/3 full with fresh, room-temperature water; tulips last longer in shallow water. Add cut-flower food to the vase. You can also nourish flowers with a solution of one teaspoon sugar and two drops liquid bleach per gallon of fresh water. <context> Start with a very clean vase.

Using a sharp knife, cut stems at a 45-degree angle so they won't sit flat in the vase.dd cut-flower food to the vase.
