A recent post by another Toronto florist had me boiling! They recommended this treatment for a wilting rose: put the stem in boiling water. Now really! Where is the science for that one?
The living tissue of a rose stem does not want to become tea just yet. Its job is to pull water up the stem to the precious bloom at the top. If a rose begins to wilt just below the flower, there is a blockage in the stem. It could be from bacteria in the water, or the stem may have been cut and left to dry a little before being placed in water. (You have ten seconds to get the fresh cut stem into water.)
To rescue the rose, have fresh cool water ready in a clean vase with properly proportioned flower food in the water. Then cut at least one inch off the bottom of the stem with clean, sharp scissors or a knife. Immediately put the rose in the water. Keep it in a bright, cool room out of direct sunlight. You also can roll it up gently in a tube of newspaper to support the head for an hour or so until the treatment works.
So be cool, and keep away from boiling water. Treat your roses kindly, and they’ll bring you much joy.
