How to care for your wholesale mixed tulips: Upon receiving your tulip flowers, inspect all flowers, take them out of the box and remove all packaging and water tubes if present. Hold the ends of the stems underwater and trim them diagonally at least ¼ inch from the ends using a sharp knife. Place your tulip flowers immediately in clean vases or containers with lots of fresh water. Keep the flowers in a dim location, away from direct sunlight, draughts or excessive heat. To maximize vase life, re-cut the stems and change the water in the vases every day using the above steps. TIP: Tulip stems have a natural bend. To encourage straighter stems, leave the sleeve on the flowers for 8-12 hours to provide support to the stems while the flowers rehydrate. Tulip heads also naturally bend to follow the light, so make sure that their light source is directly overhead.
