If you get a lovely bouquet for your birthday or anniversary it is only natural to want to keep the flowers looking beautiful as long as possible. Depending on the type of flowers in them, some bouquets will remain looking good for as long as two weeks if they are properly cared for. Roses and carnations both can last a long time after they are cut, as will bulb-grown flowers like daffodils and tulips.
Cut 1 to 2 inches off the bottoms of the flowers. Cut the stems at an angle under cool running water.
Place the flowers in a clean vase. Fill the vase with cool water, submerging the stems about 3 to 4 inches.
Sprinkle about half a packet of florist's flower food into the water.
Keep the flowers in a cool place.
Change the water every day and add half a packet of florist's flower food.
