Yan,
I found this recipe on the roots to blooms website yesterday.
"For floral fanatics, Eleanor shares her special recipe for prolonging a peony’s vase life: 1 tablespoon lemon juice or vinegar (to fight bacterial growth) and 1 tablespoon sugar (food for bloom) to one quart of water. It really works!"
Karen, have you ever been here, it's in PA, I would love to visit this garden.
