Super Tips For Fresh Flowers
On receipt of your flowers remove carefully from their packaging and place into a vase of clean, fresh water.
Roses are thirsty flowers. Check the vase regularly as roses can wilt if they cannot take up water and preservative through the stem.
If fresh roses begin to wilt, it could mean that there is air trapped in the stem. Cut off the bottom of the stem.
Check for any damage to the bark and cut the stem above this, since it can cause air to get into the stem.
Submerge the rose in warm water for about an hour and it can then go back to your display.
Roses don't like too much sunlight or extreme temperatures. Keep the roses in a cool area out of direct sunlight and drafts.
Black edges on roses
Roses are grown in areas with lots of intense light energy.
Production areas close to the equator (Colombia and Ecuador) get 12 hours of light every day of the year.
Light energy (luminosity) is strongest at the equator vs. northern latitudes.
Pigments in red roses are particularly sensitive to “sun-burning”. This condition is genetic to red, brown and purple rose varieties.
Black edged and brown “sunburn” patches result
It is this strong equatorial light that also provides us with intense colours
Temperature: Greenhouses in Latin America are mostly not heated so when there is a big difference between daytime and night time temperatures, roses respond in a way that the pigments concentrate into one place.
In yellow and pink varieties, concentrated pigments appear as red flames or intense colour chips, but in red varieties, pigments appear black.
The wide variance in daytime—night-time temps gives us HUGE head sizes
DO BLACK EDGES AFFECT VASE LIFE?
No, not at all. The black edges are simply the effect on aesthetic appearance. Some people love the vintage image of the darkened edge.
Flower Care & Maintenance for Retailers
• On delivery, carefully unpack the flowers from the box as they are fragile and bruise easily – this will also let them breath.
• Top up buckets with clean water. The flowers will be thirsty and need a good drink to advance and increase the size of the buds as packed at an immature growth stage to minimise transport damage and maximise shelf-life. Remember also to top-up regularly while flowers are on display.
• Do not change the water that the flowers are delivered in as it contains a special flower preservative that prolongs the life of the bouquet.
• Block by colour/retail where possible.
• Note that some choice flowers, especially roses, have a deep green brown pigmentation on the outer petals and tips, which may be evident due to early growth stage during production.
• Roses are grown in areas with lots of intense light energy. Pigments in red roses are particularly sensitive to ‘sun-burning’, which is genetic. Black edged and ‘sunburn’ patches result. This does not affect the shelf or vase life of the rose.
• Wilting or drooping flowers probably have blocked stems and can’t drink; cut 3cm off the stems at an angle but be careful not to crush the stems.
• Spare cut flowers should be stored at a constant temperature, approximately 5oC, away from draughts and fruit, in a cold store and not outdoors.
• Regularly check the flower display. Make sure the flowers are in water, their sleeves are in place and the display is fully stocked. Remove any tired or out of date produce.
• Check the flower section is clean and tidy with no pieces of foliage or debris on the floor or in buckets.
• Make sure all promotional ticketing is visible and prices are facing to the front.
• Remember that the cut flower display needs to be eye catching and attractive; colour blocking can add to this.
• Spare pot plants should also be stored at a constant temperature, approximately 15oC, away from draughts and fruit and not outdoors, unless for display of outdoor ranges.
• Pot plants also require watering, ensuring to keep the soil moist but not wet.
