If you're looking to expedite the opening of your cut peonies, here are a few tips: Start by placing the stems in warm water, around 100°F (37°C), to encourage faster blooming. Additionally, using a flower preservative or homemade flower food solution in the water can provide essential nutrients for accelerated growth. Trim the stems at an angle and remove any submerged leaves to improve water uptake. Position the peonies in a well-lit area with indirect sunlight to provide warmth and light that can stimulate the buds. For added moisture, lightly mist the buds with water once or twice a day.
