Now I am no expart but this is what i do to preserve roses.

I am very sorry for your loss:(

When I get a fresh bokay of roses I wait to dry them until they are almost brownish in color and droopy. Then I either take one rose at a time or the whole thing and hang it upside down as a whole. "Sometimes there are special one's you just wanna keep" I let them hang for about 2-3, weeks till crispy. I then snip off the long stem and place them in a jar. I got creative one day and hade a Rose scented candle and i put my roses in with the remains of the candle! Oh boy does it smell good!!
