What Does It Mean To Plunge Flowers In Water

Question From: B. Rueve - North Bend, Ohio, United States
Q: This site suggested to plunge daylillies in warm water for several hours before displaying them in a vace full of water and 1/2 can of non diet citrus based soda. Would you please describe what it means to plunge the daylillies?

A: It simply means to put them in a tall vase or container so the flowers are just above the water level. Best And Happy Yardening, Nancy
