If you are referring to lisianthus, then several tips come to mind. First of all, cutting underwater, then dipping into a hydration solution, then placing into WARM preservative water. Now, at one time, I think john Henry made or marketed it, there was a type of floral food called FM BudMagic. This was a solution that actually worked WELL in forcing tight blossoms to open. I am not sure if it is still being made and if it is, if john Henry is still the marketer/manufacturer for it.
