Prepare the water
Using distilled water is encouraged, because oxygen travels more easily through it and up into the stems.

Choose the appropriate vase
An optional vase is also available. Ensure the vase you select is completely clean and then add the water. Keep containers spotless and clean. Wash them with a solution of bleach before storing.

Add the "Flower food"
Dissolve the contents of one sachet of preservative into a half liter of water. Not only does flower food feed the flowers and encourage the buds to develop, but also alleviates the growth of bacteria in the water.

Cut the stems
With a sharp knife or a pair of scissors, cut about 1 1/2 inch off the bottom of each stem at a sharp angle. This is essential as it removes any dead cell tissue and also removes any airlocks in the rose stem, it also enables the maximum surface area to absorb the water. As each stem is cut, place the roses in deep, tepid water.

Display your roses
Avoid placing roses in direct sunlight, heat, humidity, or drafts. Electrical appliances will also radiate heat—causing flowers to dehydrate. Most flowers take on a special quality just before they fade. Your roses should wither and fade gently and beautifully.

Water
Change the water every second day.
To preserve the roses

Preserving an entire bouquet
Tie the roses together with a ribbon and hang them upside down for two weeks. After the two week drying period, spray the bouquet with hairspray to ensure stability.

Drying with Silica Gel
For dried roses that have the appearance of live roses, use the Silica Gel drying method. Silica Gel is available in most Craft and Hobby stores. Follow the instructions on the package. (This is the method used by professionals to dry flowers)
