Nicole - Sorry that no one has answered your question. The best answer I can give is to check out the link below, which discusses hard water and cut flowers. Two main points seem to be (1) acidify hard water for your vases. and (2) never use water from a water softener.

Here is a link that might be useful: The Care of Cut Flowers

Just to add something useful (I hope), a water softener uses sodium to help replace calcium and magnesium ions. The sodium (in the form of soluble salts) is what makes it unacceptable for use. Silver thiosulfate (STS) is now banned for use in the floral industry in the U.S. Try using demineralized (deionized) water, the kind you'd put in an old-fashioned steam iron, in place of the well water.

I have very hard water and have been using Floralife Crystal Clear with excellent results - all test bouquets are lasting 7-10 days at home, and customers are reporting about the same duration.

Thanks Pudge - do you use the Floralife crystal clear in the water you are cutting into in the field or just use it later in the vase?

I don't have a water softner and I know that this is even more detrimental than the hard water.
I can't imagine that anyone uses all deionized water on a commercial scale?

I cut into straight water that was drawn the day before and left standing to warm to the ambient temperature.

After bouquets are assembled they are left in buckets in Floralife water which was also mixed the day before. I also bundle/elastic each bouquet with a small cellophane bag on the end that holds enough water to keep the stem ends submersed.

Of course they don't!*slapping head*

I've been doing a lot of research and I'm thinking about just using citric acid to lower the Ph for the water I'm going to cut into and store. I don't think I want to use the floralife products because I am trying to do this organically.
