  • What is the proper technique for cutting rose stems?

    -Workers cut the stem at a 30 to 45° angle just above the second set of five leaves to ensure a second bloom about 40 to 55 days later, depending on the season.

  • How are fresh cut roses prepared for shipping?

    -Fresh cut roses are placed in buckets of lukewarm water with bleach to kill bacteria, checked for defects, classified by length, trimmed for equal height, and wrapped to prevent drying during shipping.

  • What conditions are necessary for the proper transportation of roses?

    -Transport trucks are refrigerated in summer and heated in winter to maintain a safe temperature of about 6° C for the roses.

  • How are dried rose bouquets prepared?

    -Dried rose bouquets are made by selecting open blooms, hanging them upside down in a fan-cooled room with good air circulation, and allowing them to dry out for a week.

  • How can the lifespan of fresh cut flowers be extended when displayed in a vase?

    -Fresh cut flowers can last about a week in water if the stem is trimmed regularly, lukewarm water with a bit of bleach is used, the water is changed every 3 days, and the flowers are kept away from direct heat.
