Conditioning
• Conditioning: The process of preparing flowers for shipment, storage, or arrangement, Usually involves a conditioning solution to prolong flower life

Types of flowers
• Line – Flower forms a point
![Page 5: 11 30 Conditioning](https://reader033.fdocuments.us/reader033/viewer/2022051512/5402f40a8d7f72f24a8b4774/html5/thumbnails/5.jpg)
Mass
• Round flowers that form the bulk of an arrangement
![Page 6: 11 30 Conditioning](https://reader033.fdocuments.us/reader033/viewer/2022051512/5402f40a8d7f72f24a8b4774/html5/thumbnails/6.jpg)
Form
• Flowers with a particular or different shape

Filler
• Small flowers with multiple blooms per stem or greenery

Transpiration
Flowers continue to transpire after they have been cut
![Page 14: 11 30 Conditioning](https://reader033.fdocuments.us/reader033/viewer/2022051512/5402f40a8d7f72f24a8b4774/html5/thumbnails/14.jpg)
Why do Cut Flowers Deteriorate?
• Low water absorption– Blocked xylem
• Loss of water– Transpiration
• Loss of food– No photosynthesis
• Disease– Botrytis (fungus causes brown leaves)
• Ethylene Gas– Produced by fruit and deteriorating plant material
![Page 15: 11 30 Conditioning](https://reader033.fdocuments.us/reader033/viewer/2022051512/5402f40a8d7f72f24a8b4774/html5/thumbnails/15.jpg)
Conditioning
• Replaces & prevents the conditions that cause deterioration
• Use a chemical mixture • Florists use “Floral Life”• You can use Sprite or 7-up
![Page 16: 11 30 Conditioning](https://reader033.fdocuments.us/reader033/viewer/2022051512/5402f40a8d7f72f24a8b4774/html5/thumbnails/16.jpg)
Conditioned water
• Lower pH – acidic water (pH3.2 – 4.5) maximizes hydration & slows bacterial growth
• Provide nutrition – glucose/sugar• Kill bacteria and fungus – preservative
![Page 17: 11 30 Conditioning](https://reader033.fdocuments.us/reader033/viewer/2022051512/5402f40a8d7f72f24a8b4774/html5/thumbnails/17.jpg)
Conditioning old flowers• Replace the water every 2 – 3 days
– Use warm water for maximum absorption– Mix 1 heaping TBS conditioner per quart of water – Stir until dissolved
• Cut flowers on a slant 2” from bottom or above any decay
• Remove any wilted leaves or flowers and any leaves that would be submerged
• Replace in clean containers w/ 3-4” of solution in the bottom.

Receiving New Flowers• Unpack
– (Not Roses – until ready for them to open)• Remove any that are browned or diseased• Recut the stems
– Cut 2” from end– Cut on a slant
• prevents stem from sitting flat on the bottom• Allows more surface area
– Place in warm conditioned water.• Allow 30 min to 1 hour out of the cooler to rehydrate
after shipping

Receiving Flowers
• Roses: Cut stems under water– Prevents air bubble blockage
• Milky or sappy flowers– Burn the end with a candle
• Remove all foliage that will be underwater– Slows bacterial growth
