Cool tulips - tulips like cold water
Most bouquets do not like cold water, tulips are an exception.
The best way to put tulip bouquets in cold water after cutting (oblique and not too long) is to put some ice cubes into the water - that's how you can enjoy them for a long time.
As with other cut flowers also applies here: Approx. Add new water every two days, do not expose to direct sunlight, do not place directly next to the fruit bowl and avoid drafts. Possibly. store at night in a cooler room.
