A subscriber has requested clarification about the utilization of a floral conditioning solution (e.g. Chrysal RVB) vs. a floral preservative solution (e.g. Floralife, Oasis or Chrysal Cut Flower Food). The concern is well founded because the terms are readily bewildered and somewhat misleading. First, please note the use of the terms conditioning and hardening in the past post. These terms describe two time periods in the processing of cut flowers. Confusion places in because both conditioning and preservative solutions may be used throughout the hardening and conditioning intervals! To thoroughly describe using solutions with cut flowers, lets first qualify the whole cut-blossom procedure (from the perspective of a rose exhibitor) as follows.Now, the question arises: which solution is suitable for which time period? You should first know how to draw a rose before buying pencils. Generally, a floral preservative (cut flower food) could be used for all five spans, but a conditioning solution (Chrysal RVB) can exclusively be useful for Measures 1 4 that is thorough.A floral preservative contains an agent to kill bacteria, an ingredient to acidify or lower the water pH (which makes it more easy for the stalk to take up water), plus a nutrient to feed the bloom.
Note: these three elements are additionally contained by Listerine mouth wash and is therefore recommended as a floral preservative that is home made.Because a there is (a type of sugar) a nutrient within the floral preservative solution, the solution has to be shifted every three days roughly during Measures 4 and 5,. The container comes, and also has to be altered or washed with soap and/or bleach only at that time re-cut to expose clean surfaces. While the anti-bacterial agent fights stalk rot, the nutrient encourages it, therefore the situation is balancing act or a stand-off.Now, the floral conditioning option is significantly different. It was designed to re-hydrate bloom stems which have been shipped out-of.
Sadly, this substance can do damage if stems are left standing in it to get a prolonged time frame (say, more than 12 hours) at room temperature, hence, the conditioning solution is just not suitable for Step 5 in the cut bloom process!The great news: roses can stand in the conditioning solution for two weeks or even more in cold storage, without re- cutting stems or changing solution!Theoretically, the process that is optimum would be to use a conditioning solution for Measures 1 and 2 (through the conditioning period, obviously) as well as a preservative solution for Steps 3 through 5, changing it as frequently as required. However, for expediency, I’ve used only conditioning solution for Measures 1 through 4, and tap water afterward. Not merely does it minimize the job of holding roses in cold storage, it tends to fix the periods of blooms, rather than supporting blooms to carry on development, as a nutrient would do. Note: a couple of years ago, dry-wrapping roses to hold them was all the rage among enthusiastic rose exhibitors.
That was before the discovery of the conditioning solution Chrysal RVB, made by Pokon Industries in The Netherlands. Should you dry-wrap, a conditioning option would be ideal for re-hydration.To summarize: A conditioning alternative is designed to increase hydration of a cut flower, especially if the bloom has been out for some time. It may also be used for hardening and cold storage, and is notably useful for prolonged cold storage. A preservative solution was made to extend the life span of a cut flower, while retarding bacterial rot, providing nourishment. The solution should be changed and also the container cleaned every three days or so, to succeed, although it may be used throughout the cut flower procedure.
