Roses date back to ancient Babylonian, Greek and Roman civilizations and are very adaptable to and grow in cool temperature or sub tropical climates. Roses are very versatile and can be grown in the open or under controlled glasshouse conditions. Regular fertilization is required for vigorous growth and good-sized quality flowers. Roses need a regular supply of organic and chemical fertilizers for best results.

One week prior to cutting flowers, apply 400ml Grow Green Profert Phos and 10ml Xtend plant oil adjuvant per 100m2. This will ensure that a boost of nutrient supplement is provided to enhance bloom color, stem strength and improve cut flower life.

Post Harvest Storage Temperature:

Temperature: 0°C to 1°C
Relative Humidity: 90% to 95%

Deterioration Factors:

• Chilling injury below -0.5°C
• High temperatures
• Ethylene contamination
• Do not place with narcissus
• Poor handling practice
• Excessive sugar.
  
  

L.L.S. Critical Path:

• Cut stems on an angle, place in a bucket of water and transport to packhouse
• Pre chill at 0°C to 1°C
• Treat for Botrytis
• Re-cut stems underwater in preservative solution
• Use citric acid solution (250ppm, 0.25g/L) for 1 - 2 hours at 20°C or 12 to 24 hours at 1°C. This will prevent air embolism from blocking stem
• Dry pack stem into well vented carton lined with LLS smartbag
• Add 2 x ethylene sachets and close bag and then close carton
• There is no need to pack in water
• Restore in controlled temperatures
• Load transport at low ambient temperatures
• Keep refrigerated at all times for maximum life extension

Summary:

Whilst the storage life of roses, can be extended at 1°C for up to 21 days dry packed. Avoid exposure to high ambient temperatures. For maximum life extension, maintain the "cool chain" at 0°C to 1°C.
