Protection against ethylene

  • Protect poinsettias against ethylene—they are sensitive!
  • Ethylene Buster (EB) is eco friendly, easy and flexible.
  • Available in two delivery methods: truck kits for large areas and trailers and sachets for boxes.
  • Size of area determines how many pills or sachets are needed for protection
  • L x W x H = volume of area to treat
  • Truck kits:  Determine amount of pills for space treated. 1 pill treats 375ft3.
  • Drop EB pills into activator pot. Replace lid.  Water activates the release of the gas
  • Moisten sachets in water before dropping into shipping boxes.
  • Close holes to trap gas inside
  • Allow 4 hours minimum for treatment.

Avoid ethylene exposure.

–  Never expose or store poinsettias in same area as Douglas fir or Redwood. Both types of foliage produce LOTS of ethylene.

–  Make sure no cigarette smoke drifts in from the back dock smokers’ corner



  • These plants like bright (indirect) light.
  • These Mexican natives love indoor temperatures between 65F—75F


Out of Sleeves, fast!

  • Remove sleeves as soon as the shipment arrives. Handle with care as bracts snap easily.
  • Delivering in cold climates?  Paper sleeves will not protect against chill damage.
  • Get out the frost pack and blanket poinsettias for successful deliveries.


  • Overwatering and/or letting plants sit in water kills most plants—poinsettias included
  • Every 8-10 days is sufficient.
  • Allow water to drain completely through the pot to avoid accumulation of salts in the soil profile. Salt accumulation causes burning on leaf margins.
  • Take care to keep the leaves and red bracts dry.
  • Remove pot cover, slowly soak soil surface (tepid water) until water flows out the bottom.  Then repeat the same action so air pockets in soil are completely filled with water.
  • Never leave the pot submerged. Roots drown without oxygen.
  • Don’t worry about fertilizing; growers prep plants with enough food to sustain them through their month-long beauty pageant


How to maximize the cool berries available for holiday designs—think holly, callicarpa (beauty berry), symphoricarpos (coral berry), rose hips, seeded eucalyptus, privet, mistletoe…



  • Store really cold (33-34F) at temps higher than 35F, it starts deteriorating fast
  • Don’t spray wholly with oil-based shines—causes black berries
  • Chrysal Leaf Shine is silicon-based or water based. Works fine on holly!
  • Berries turn black and fall off when exposed to ethylene. Use Ethylene Buster in coolers for protection

Symphoricarpos and Callicarpa:

  • Treat these gems as cuts and process into Chrysal Professional #2.
  • Both products are ethylene sensitive (berries fall off). Italian research shows that treating with Ethylene Buster (1MCP) improves vase life from 5 to 9 days.

Rose Hips:

  • Store dry and cold. Studies at NC State found neither hydration or flower flood solutions resulted in significant vase life improvement when hips are treated


  • Hold cold and dry unless you plan on extended rotation. In that case, hydrate bunches in Professional #1 or Professional #2.
  • Leaves discolor if sugar level is over 2%
  • Eucalyptus produces LOTS of ethylene when dehydrated.

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

It is important to cut off a piece (at least 2-5 cm) of the stem if the flowers have been out of water for about 30 minutes.

The knife or secateurs or other cutting device should always be kept sharp.  This is very important, since blunt blades will crush the flower stems, which will result in more damaged and leaking cells that stimulate the micro-organisms growth and resulting loss of vase life.

The knives and secateurs must also be extremely clean.  Dirty tools will infect the cut surface and therefore the vase water, which negatively affects the flower development.  A florist should disinfect his/her tools at least on a daily basis and ideally sharpen them.  Good tools are on the top of the list for important florist supply.  The consumer should clean his/ her knife or secateurs before each use.  If using rose bush tools make sure to properly scrub them.




Winner of the
2011 SAF Gold Medal Award

The prestigious SAF Gold Medal Award honors the originator and introducer of a widely distributed plant or flower that has become and outstanding product of significant horticultural and commercial value.

John Dolan’s name is synonymous with many of the top rose varieties grown in the US and Latin America. A trailblazer, John tirelessly worked to open up Latin America to US bred roses. Though his insight, knowledge, hands-on experience and honesty, John introduced award winning varieties into Colombia and Ecuador. He was the force behind the 30 million plants of ‘Classy’ and more than 30 million plants of the #1 variety in Eastern Europe, ‘Forever Young’.

Anyone who has had the fortune to spend an hour with John, quickly realizes the depth of his expertise includes far more than production numbers and variety selections. He is well-versed on politics, golf, fiscal analysis, soccer and history, too! His dedication to the industry is obvious in years spent in various offices including the Board of Governors-Plant Producers, treasure of Roses Inc,  long time director of The Hill Memorial Fund, and more than fifteen years as the VP and President of IRBA. John, with help from other breeders and RAI was integral to the plant patent law getting passed in Colombia and Ecuador. Growers appreciated John’s honesty while negotiating plant sales as he never hesitated to recommend a competitor’s variety if it out-performed one of his own.


John’s legacy includes introductions of these varieties.

Expoflora is the largest exhibition of flowers and plants in Latin America.  This annual flower show in Holambra,Brasil, a Dutch-founded city that’s the country’s largest flower producer.  Besides a great display of flowers and plants, there are music performances and traditional dances of the Netherlands, Dutch cuisine contest, landscaping and rain of petals each afternoon.

The event takes place during the month of September, this year Chrysal sponsored the flower sales stand with sachets. Margriet Kroon, a Chrysal International Technical Consultant, captured these wonderful images for us to share.

This year, Holambra was officially recognized by Brazil president Dilma Rousseff as the National Flower Capital.  Holambra was started in 1948 when group emigration fromHolland took place. Whole groups of families emigrated to Brasil after the second world war. Nowadays Holambra is the centre of the flower production and trade and still has a strong link with Holland.

The Ride is a mass cycle ride to raise money for KWF Kankerbestrijding (the Dutch Cancer Society). Cancer is something that can strike any of us! Modeled on Lance Armstrong’s original initiative, the Dutch version of Ride for the Roses has been held annually since 1998. The Ride took place September 4th this year.

Chysal was happy to sponsor and participate again in the “Pre Ride for the Roses” as well as the “Ride for the Roses”.
The Pre Ride involves small teams of all the flower auctions (so Aalsmeer, Naaldwijk, Rijnsburg, et cet) and additional sponsors from the horticultural business. They main target of the Ride and the Pre Ride is to raise money for the KWF foundation to support cancer research. Chrysal donated rose sachets for the retail promotion done with Albert Heijn.

The Ride raised a total amount of € 1.517.535,27 for the KWF foundation. We’re proud to be part of this and want to thank the team for their participation and enthusiasm to do so.

Times are tough and so are wedding budgets.  Recently our friend Brett at Forever Blossoms was asked to do a small wedding for a friend.  The wedding was intimate and took place at a private home with only 20 guest.  The bride originally wanted white phaleonopsis orchids, but being on a budget, couldn’t afford the cost.  She opted for green and white dendrobium orchids instead, keeping her cost down without sacrificing the simple and elegant look she wanted to achieve.  An assortment of tropical greens including ti leaves, aspidistra, and bear grass helped give the arrangements volume and texture.

Brett took a sticky situation and made these marvelous arrangements, our favorite was the elegant and fun bouquet.  We often hear brides asking for expensive varieties like Callas, Hydrangeas and Orchids but tend to get sticker shock when they hear the price.  Several florist told us that they use color schemes to keep the customer happy when substituting flowers due to budgets.

How much do your wedding flowers cost.

Sediment due to combination of hard water and non clear cut flower food in Rose stem

When using hard water (high alkalinity, high lime concentrations) as basis for the vase solution, a white sediment might be seen at the bottom of the vase which looks like

Sediment at the bottom of vase

non-dissolved powder.  However, this is the precipitation of the lime in the water with some of the water purifiers.  Only when so called “non-clear” cut flower foods are used, this phenomena occurs.  the more sophisticated clear cut flower foods are, the more they keep the vase solution free from precipitations.

Whats in the flower foods?

Cut flower foods contain the following active ingredients:

  • water purifiers
  • water clarifiers
  • water softeners
  • pH regulators
  • water uptake regulators
  • plant growth regulators
  • energy carriers
