How long should my roses last?
Depending on the season commercially grown roses should last
5-10 days.
When you receive your roses you want to add fresh water.
Keep them away from direct light and heat.
Bacteria growing in the water will shorten the life of your roses so
adding just a few drops of bleach to the fresh water can keep bacteria from
growing.
When buying roses wrapped be sure you are provided with
flower food this balances the ph and helps with bacteria growth. Cut stems at a slight slant and place in room
temp water in a clean vase as soon as you get home. Change out the water every other
day.
Bent head is when your roses droop at the top of the stem by
the head. This is caused by the water supply not going up the stem. If there is
a problem with this it will usually happen in the first 24 hours you receive
your roses. Most florists guarantee
their flowers and would want to know of this situation right away. Don’t
hesitate to call and let them know.
Make your own flower food: 1 teaspoon sugar, 1 teaspoon
liquid bleach, and 2 teaspoons lemon or lime juice mixed in 1 gallon of
lukewarm water.
Why didn’t my roses open?
Black edges can happen for two reasons light and temperature
Light:
The strong equatorial light is also what provides us intense rose colors.
Most greenhouses in Latin America are not heated. When there is a big difference between daytime and night time temperatures, roses reaction to these fluctuation in such a way that the pigments concentrate. In yellow and pink roses, concentrated pigments appear as red flames or intense color chips, but in red varieties, pigments appear black. These pigmentation's do not affect the longevity of the rose.
Why didn’t my roses open?
There are several reasons why roses do not open. They may
have been cut too early at the farm. They were not properly hydrated or they
were out of water too long. Some
cultivars are for longevity and while they have a long nice vase life they
never open.
I just got my roses and they are wilted. What can I do to
revive them?
Using a knife re-cut the stems of the rose an angle. Submerge
the entire rose including the stem and leaves in warm water in bathtub. The
rose usually revives again within an hour and can be replaced in the
arrangement. Sometimes air gets trapped inside the stem and keeps the rose from
drinking. Submersing roses underwater helps to push out any air bubbles that
may be trapped.
Where are commercially grown roses grown?
Most commercially grown roses in the US are grown in
Columbia and Ecuador & California in the higher elevations. They are grown
in green houses. The higher the elevation the longer stem they produce.
Why do roses get black or dark edges on petals?
Black edges can happen for two reasons light and temperature
Light:
Roses are grown in areas with lots of intense light
energy. Production areas close to the equator get 12 hours light everyday
of the year.
Pigments in red roses are particularly sensitive to “sun-burning”. This condition is genetic to red, brown and purple rose varieties

The good thing about the large fluctuation in temperatures
is that it gives us a nice large rose head.
