One of my botany professors insisted on using the sharpest tool and perform the "trim cut" under water. This prevents an air bubble from forming in the vascular tissues. The air bubble prevents normal "capillary" draw from occurring properly.
Cool! Thank you!
@John Temmel Siding Guy a commercial preservative or sprite and a drop or two of bleach will extend the life in the vase. Should also cut about an inch above the last cup just before putting them into the water. Apparently it should be a sharp knife rather than scissors so as not to squish the stem together causing blockage.
I posted these tips for Valentine's Day, but they apply to any cut flowers:
Thank you Douglas!
Mix 1/3 lemon-lime soda with 2/3 water and every couple of days snip the end of the stems off at a angle to provide a large surface area for the flowers to absorb the water solution.
Thank you everyone for these wonderful suggestions! Can't wait to try them :)
I heard a tip just a few days ago that I have yet to try.... After trimming off all excess leaves and cutting stems in a slant, insert flowers into fresh water and then add two teaspoons of vodka. I am going to try this one soon.
