Although they are real roses, it's best to not water them and to avoid direct sunlight.The preservation process pretty much does the hard work for you. If you want them to last as long as possible, even beyond a year, keep them in a room-temperature location that won't get crushed or pushed around. I keep my Venus Et Fleur Small Round ($299) arrangement as a centrepiece on our foyer table. I use a feather duster to lightly remove any dust or debris.
