To ensure your Luxury Hydrangea Flowers Bouquet remains vibrant and beautiful for as long as possible, proper care is essential. Hydrangeas are known for their thirst, so it's crucial to keep them well-hydrated. Upon arrival, trim the stems at a 45-degree angle and place the flowers in a clean vase filled with fresh, cool water. Change the water daily, and re-trim the stems each time. Hydrangeas also benefit from frequent misting, especially in warm weather. Keep the bouquet away from direct sunlight, drafts and extreme temperatures. With proper care, your hydrangea bouquet will bring joy and beauty for an extended period.
