Care of Red Burgundy Hydrangeas flowers:  Upon arrival remove all packaging and cut stems diagonally approx 1 inch from the end under running water with a sharp knife. (Hydrangea flower stems are woody so make sure your blade is up to the job!). You may cut slits or fray the ends of the stems also to allow the flowers to take up as much water as possible. After cutting, place the ends of the stems immediately in warm water for 5 seconds, then transfer to a clean vase filled with lots of fresh, cool water and add floral preservative. Remove any fading petals. Hydrangeas flowers are fast drinkers so remember to keep refreshing and filling the water in the vases, especially overnight. It is normal for hydrangeas to appear sleepy or thirsty upon arrival and they need 24hrs to re-hydrate after their journey. Keep flowers away from direct sunlight, drafts, excessive heat. Re-cut stems and refresh water every 1-2 days to help your hydrangeas flowers live long and beautifully. TIP: To refresh your hydrangeas, dunk the entire flower heads in cool water and allow them to remain submerged for approx 20 mins. Also, hydrangeas make great dried flowers. If you wish to preserve your hydrangeas bridal flower bouquet, hang the bouquet upside down in a warm location for a few days after the wedding. Dried hydrangea flower arrangements last typically for around 8 months.
