If you plunge them up to their necks in very hot water before arranging them it will make them last longer, and even revive them if they have wilted a little.
Bacteria in the water is what causes flowers to wilt and rot. This is something you DON'T want in the water. Other things to keep out of the flower's water are leaves from the stem. They will break down in the water and cause bacteria growth. You will want to change the water in the vase regularly, adding bleach or vodka (and flower food, aspirin or sugar each time).
Keep your flowers beautiful by keeping them cool at night (maybe even in the refrigerator) and away from any sources of heat. Trim the stems daily. A thin film grows over the bottom of a cut flower's stem, impeding their ability to take in water. Prevent this by regularly trimming the stems bottom. Flowers with woody stems, such as roses, should have the bottoms of their stems crushed slightly as well.
Theoretically, they should survive roughly the same time in both types of water. They might survive for a little longer in mineral water. The only sure way to find out would be to experiment
roses will not live long if a lot of water is added only add water to cover half an inch of the bottom of the stem and a whole packet of flower food to have beautiful long lasing roses.
=yes it will help you live longer=
Keep them well fed and disease free and cut out any dead or weak wood annually.
there is no such thing of prarie roses.
