Most freshly cut roses will last up to a week if properly cared for. Use a clean vase and fill it with fresh, tepid water with some cut flower food.
You may notice that some of the outside petals on the rose look slightly damaged. Don’t worry, these are called the guard petals and, as the name suggests, they are there to protect the flower on delivery. Gently peel these away and remove any leaves that will sit under the water (otherwise it could go a bit murky). Finally trim the bottom of the rose stem at an angle before placing in the vase.
To keep your roses looking good for as long as possible there are a couple of things you can do. Place your vase away from direct sunlight and heat, regularly change the water to keep everything fresh and finally give the stems a little trim every few days – it helps them to keep on drinking!
