Here are some situations and solutions that are often encountered when it comes to gerberas.
SITUATION: A box of expensive Dutch gerbera daisies have gone limp because the customer did not pick up (kept pushing the order forward). Finally (day 6) we gave up on the customer, cut stems and placed in water with Chrysal gerbera pills. Holding buckets out of cooler after 2 hours, stems are turgid but petals are still limp.
QUESTIONS: Should we spritz, dunk, submerge the blooms? Keep waiting? Normally, I would worry about botrytis infection if we get the heads wet, but blooms will be put into action on Tuesday. Also our environment is very dry. What else can we do?
SOLUTION: You’ve done everything right so far.
- Avoid dunking, spritzing or submerging blooms—too much handling causes mechanical damage, too much water ramps up disease pressure
- Once stems are full of super clean water (4-6 hrs), transfer into Chrysal Professional 2 solution. Pro 2 provides the carbo-load so petals firm up and colors stay vibrant
- When you transfer blooms into Professional 2, move buckets into cooler.
SITUATION: Gerbera blooms are locked in side-facing position. I want them to look up, not sideways.
SOLUTION: Take stems out of water and out of cooler for several hours so they get thirsty.
- Prepare cold water (34-36F) with Chrysal Gerbera pills (1 pill/ half gallon water)
- Cut stems, with a clean, sharp knife. Make sure to give a fresh cut above the “heel” (white tissue at bottom of stem)
- Plunge stems into solution. Shallow water level-3-4”
- When flowers go into buckets, make support stems upright, no hang-overs in bucket. Make a grid with tape on top of processing bucket so stems hang vertical, but don’t suffer scrapes or wounds as flowers are slotted
- Place buckets in cooler so stems harden-off fast
- Design Gerberas as usual vase flower food
SITUATION: Gerberas arrive with petals reflexing down toward the floor rather than horizontal position
SOLUTION: Contact vendor and explain the blooms appear to be cut too soon and you’ll need a replacement.
