With Valentine’s being weeks away, Chrysal wants to make sure you have all of the information regarding your Valentine’s flowers at your fingertips! To continue our countdown to February 14th, here is all you need to know about roses! Below are two very important things you must know and don’t forget to share with your customers.
1. Correct cut point timing ensures proper bloom development
Rose buds attain maximum bud size in the final 3-7 days before harvest
- Buds accumulate carbohydrate stores to ensure bloom opening
- Bud size increases. Customers love those larger heads!
- Foliage tissues are actively storing sugars, water and hormones to guard against harvest stress
- Varieties with a high petal count require an open cut stage to develop
- Roses must arrive to stores at stage 3-4 for 100% development
- Rose blooms cut too tight mean buds will never open
Don’t expect customers to know about changes in rose cut point. For years, we diligently trained them to accept bullet tight, over-peeled roses as “fresh”. Now they are confused on how to judge flower quality. As a flower expert, it is your privilege and responsibility to educate your customers!
Where’s the fragrance?
The sweeter the fragrance the shorter the vase life. Breeders choose varieties with long vase life so don’t be alarmed if the fragrance isn’t as sweet.
2. Resist the urge to peel guard petals and foliage if you want your roses to last longer
Groom guard petals if needed, otherwise leave intact.
- Removing guard petals loosens the bud and promotes opening
- Peeling guard petals triggers the onset of ethylene production. Ethylene reduces vase life and hastens death in flowers.
- Ethylene production starts at the point where the petal attaches to the Calyx
When should I peel guard petals?
Peel ONLY if guard petals show blemishes or disease problems.
- Guard petals with damaged spots, creases, streaks or tears
- Guards petals that are excessively black—so much so, it impairs salability
- Guard petals with raised blister look of Botrytis
Why should I keep foliage?
Specialized cells on the underside of foliage pull solution up to the stem into the bloom. Remove only those leaves underwater (to control solution pollution). See our previous blog piece “Should you strip your roses?” about the effects of stripping roses of thorns and foliage.
