Anytime you pick up flowers from the store or florist, you'll want to refresh the stems by trimming them an additional half an inch or so, even if they've already been cut. This also applies to flowers that have been delivered or cultivated in a greenhouse. To put it simply, always trim and prune fresh flowers, no matter where they came from. Get in the habit of dumping out and replacing the water in your flower vase every morning, or as soon as it starts to get murky. Fresh flowers need a lot to drink, so don't hesitate to top off the water level if you notice it getting low. Be sure to add a pinch of plant food to help your flowers flourish.  To refill the water in large decorative arrangements, tilt the vase over the sink to empty it, then run fresh water over the stems using a watering can or measuring cup. Waiting too long between waterings can lead to rot, which causes the blossoms to wilt and produces an unpleasant smell. Since cut flowers have been separated from their root system, they won't be able to survive as long as they would in the soil (no matter how fresh they are). You can prepare your flowers for their new environment by sprinkling half a packet of organic plant food into the vase prior to inserting them. Plant food contains essential nutrients as well as antimicrobial additives to slow the growth of mold and bacteria.  You can purchase plant food at any gardening center or greenhouse, or in the home-and-garden section of most supermarkets. Alternatively, you can whip up your own plant food at home by combining 1 tablespoon (14.8 ml) of sugar, 2 tablespoons (29.6 ml) of lemon juice, and 1 teaspoon (4.93 ml) bleach and adding them to 1 quart (0.95 L) water. Pour the mixture into the vase. Most types of flowers fare best in mild, moderate conditions. Temperatures between 65 °F (18 °C) and 72 °F (22 °C) are ideal, though a couple of degrees higher or lower shouldn't make too much of a difference. Make sure your flowers get plenty of sunlight, but situate them away from the most intense glare to keep them from overheating.  Some heartier species like roses and orchids prefer a warmer environment. It's safe to store these flowers in hotter areas, such as your kitchen, or even outdoors on a sunny day. It's fine to keep your flowers' water at room temperature. You can also try adding a couple small ice cubes to the water, which may help the blooms survive a little longer.
