Ideal Water Temperature for Flowers?

QUESTION: What water temperature is best for my cut flowers- I've always heard warm water is best... but NOW people are a saying Cold? What's your expert opinion J?ANSWER: This is one of the most popular questions at both my Live Events and on line...  For years we were told that Bathtub warm water was best for our flowers... But recent research is proving that Warm Water is detrimental to our flowers... and doesn't help flowers last longer...First... Warm/Hot Water contains a great deal of air... think about how a glass of warm water is cloudy... that's the air in the water... that same air goes up the stem and doesn't hydrate the flower... in fact it does just the opposite...Secondly... Warm/Hot water starts to degrade the stem of the flower... think about cooking asparagus... hot water... means softer stems... while that's delicious for Asparagus and other veggies... it's bad for the flowers... and warm water breeds bacteria faster... when the flower stems start to deteriorate ... they make bacteria soup quickly in warm water... the result is shorter vase life...So... We're finding that COLD Water... even ICE COLD Water is better for flowers... the flowers are able to absorb it better... and it detours bacteria growth...You can mix up your flower food water... and put it in a jug or recycled container and put it in the refrigerator to cool it down... great idea... Or... if you need to cool it down fast... add Ice to the water... but remember to measure the water with the ice... THEN add your flower food... you don't want to add ice to flower food water...  it will dilute the flower food and that's not good either...Thus the ANSWER... COLD Water (ICE COLD) 40 Degrees F or lower is best for your flower arrangement... the flowers will do better... open more uniformly and last longer... Thanks for the question!
