Flower stems are bound together with an elastic band or other type of binding material. Although it is common practice, some binding materials can have a
negative effect on the vase life. The same is true for Gerbera when it is supported or pierced by a metal wire.
Elastic bands are no problem; they are made of inert material. Natural fibers, such as raffia, rope etc., cause problems if they are biologically contaminated. In addition, they can serve as food for bacteria that may be present, particularly in vases only containing tap water i.e. no flower food.
Uncovered / protected metals are corrosive in the acidic vase water (pH 4-5) and release metal particles that are “toxic” for flowers. This can lead to stem, leaf and flower damage. Gerbera is often reinforced with a wire. In the vase, this wire can begin to rust, which shortens the vase life of the Gerbera. Keeping the vases and the vase water clean, using flower food and correct dosing will help to keep the Gerbera stems straight.
• Purchase Gerbera varieties with
strong stems that do not require the support of a wire.
• Use Chrysal CVBN to condition
Gerbera and help them “stand strong”.
• If you must use binding material,
only use completely plasticized wire or aluminum wire.
• Use inert, non organic binding
