Please keep flowers away from direct sunlight in a cool spot away from any source of heat (e.g. candles, stove, heaters etc)
Change water every 3-4 days, ice cold water preferred and give stems a 0.5 inch trim when you’re changing water. Keep 3/4 of a vase filled with water.
Some flowers are in a full bloom while the other are just about to open up, thus they will have a different vase life. When you see one flower wilting, just gently remove it so it does not affect the rest of them.
Enjoy
