How Do I keep My Roses Living Longer?

A part of my Valentine's gifts from my boyfriend was a dozen roses.. I've had roses from him before, and I find that they die fairly quickly.. Is there anything I can do to make them live longer?

How Do I keep My Roses Living Longer?
could you trade them and get the fake ones? ha ha, but you already got your answer put them in water.
Reply:make sure the ends are cut at an angle and do this every few days. Some people say putting an aspirin in the water helps extend their life. Others swear by a penny. Most florists have powdered flower food you can put into the water.
Reply:Put an asprin in the water. DO NOT put them in bleach. If this is a first Vday together, cut one off and freeze it for later, when they're all dead, make potpourri.
Reply:Stare at them, see how long they last.
Reply:use plant food in the water %26amp; change the water every day......it'll keep it a lil bit longer, but roses always die in a few days, thats why I dont like them. they're beautiful, but Id rather have bright color flowers like tulips %26amp; lillies that lost longer %26amp; look great :) enjoy them tho!





when they start to die, hand them upside down to dry them out %26amp; save them!
Reply:Cold water with aspirin (the food the florist use is to make the flowers open, not to make them last longer, I asked a florist)
Reply:sit them in bleach...
