How to Make Cut Roses Bloom Overnight

Cut roses in the late evening. Use sharp kitchen or garden shears to avoid crushing the stems. Carry a container of warm water to the garden with you and submerge the stems immediately to prevent air bubbles from traveling up the stem and inhibiting water uptake. The water temperature should be between 100 and 110 degrees Fahrenheit, according to James Schmidt, horticulturist at the University of Illinois.

Strip away leaves that will be below water level in the vase. Remove any diseased or insect-bitten leaves and petals as well.

Mix up a homemade preservative to extend the life of the flowers. Combine 1 pint of a non-diet, lemon-lime soda with 1/2 teaspoon of bleach and 1 pint of warm water in a container. Pour the solution into a clean vase.

Recut the stems at a diagonal angle under warm, running water. Remove at least 1 to 2 inches of stem from the roses.

Quickly transfer the roses to a bucket of hot water and allow them to sit for a few minutes. Do not leave the flowers for more than 3 to 4 minutes or you will kill the flowers.

Move the roses to the vase of preservative-enhanced water and store the container in a cool, humid place overnight. Do not dilute the solution. The University of Nebraska recommends the refrigerator as an ideal place for storing it.
