If you like fresh cut flowers or have a wonderful hubby who on occasion brings them home for you here are a few tricks to make them last longer so you can enjoy them more.
When you first receive them don't just unwrap them and stick them in a vase. Pick a vase large enough for the arrangement. Fill it 1/2 to 3/4 full with lukewarm water. Lukewarm or room tempature water will move thru the stems faster than cold water. Then take a sharp knife or heavy duty kitchen scissors (I prefer the scissors) and cut each stem at an angle as short or long as you want. When flowers are cut the part that is cut will eventually start to seal over or close up therefore making the water harder to get thru the stem. Cutting them again when you receive them opens them back up again to allow the flow of water thru. Then place the arrangement in your vase. Each day you should change the water with more lukewarm water. As certain flowers die out remove them and keep arranging your flowers. I've had arrangements last up to two weeks by tending to them daily.
I've also heard adding an aspirin to the water helps but I have not personally tried this.
