Simple care, longer life.
Cut flowers are living things on borrowed time — a little care goes a long way toward stretching that time out. Here's how to help your arrangement look its best for as long as possible.
The Basics
Trim the stems. Cut about an inch off each stem at a 45-degree angle before placing flowers in water. The angle creates more surface area for water uptake and keeps the stem from sitting flat against the bottom of the vase. Use sharp scissors or a floral knife — crushed stems from dull blades struggle to drink.
Change the water every 2–3 days. Bacteria builds up in vase water quickly, and that bacteria is what actually kills flowers faster than age does. Empty the vase, rinse it out, and refill with fresh cool water each time.
Re-cut the stems when you change the water. Another quarter-inch trim each time keeps the cut end fresh and able to drink.
Keep foliage out of the water. Any leaves sitting below the waterline will rot and speed up bacterial growth. Strip them before placing stems in the vase.
Find a cool spot, out of direct sun. Heat speeds up the aging process. Keep arrangements away from direct sunlight, heating vents, and appliances that generate warmth.
Keep them away from fruit. Ripening fruit releases ethylene gas, which accelerates wilting. Don't display arrangements near a fruit bowl.

Additional Tips for Even Longer Stem Life
A few more advanced techniques, for anyone who wants to push their arrangement's lifespan further than the basics cover.
Use Flower Food (or a Homemade Alternative): Packaged flower food does three things: feeds the stems sugar, lowers the water's pH to help uptake, and includes a mild antibacterial agent. If you don't have packets on hand, a homemade mix works reasonably well: 1 quart water, 1 tablespoon sugar, 2 tablespoons white vinegar or fresh lemon juice, and a few drops of bleach. Mix fresh each time you change the water — it doesn't keep.
Sear or Sterilize Stems That "Bleed": Some stems — poppies, hellebores, dahlias, and a few others — release sap that can clog the stem and block water uptake. Searing the cut end briefly in boiling water or over a flame for a few seconds seals it and helps the stem drink normally. This is a florist trick that home care instructions often skip entirely.
Give Woody Stems a Head Start: Branches, lilac, hydrangea, and other woody-stemmed material benefit from a shallow vertical cut (about an inch, up the center of the stem) in addition to the angled cut. This exposes more surface area to water and helps stiffer stems take up water they'd otherwise struggle with.
Mind the Room's Humidity: Dry, heated indoor air in winter pulls moisture out of blooms faster than most people expect. A light mist of cool water on petals (avoiding the center of the bloom) once a day can help, especially for hydrangea and peony.
Move Arrangements at Night: If it's practical, moving an arrangement to the coolest room in the house overnight — away from residual daytime heat — can meaningfully extend bloom life, the same way florists keep stock in coolers overnight.
Isolate Any Fading Stems Early: Once one stem starts to decline, its decomposition speeds up bacterial growth for the whole arrangement. Pulling a fading stem as soon as you notice it — rather than waiting for a full refresh — protects the rest of the piece.
Ice Cubes for Delicate Blooms in Warm Weather: For very heat-sensitive blooms (ranunculus and anemone especially), adding a few ice cubes to the vase water on hot days can slow their metabolism slightly and buy an extra day or two, particularly if the room runs warm.
Vase Life Info
How long to expect each flower to hold, with proper care: Vase life varies with growing conditions, how fresh the stems were at cutting, and how closely you follow the care steps above — these ranges assume good care (fresh cuts, clean water, cool placement).
Bloom Average Vase Life
Ranunculus 7–10 days
Anemone 5–8 days
Calla Lily 7–14 days
Carnation 14–21 days
Dianthus 7–14 days
Scabiosa 6–8 days
Peony 5–7 days open (up to 10 in tight bud)
Tulip 5–7 days
Dahlia5–7 days
Hydrangea 5–7 days
Hyacinth5–8 days
Gerbera 4–7 days
Allium10–14 days
Orchid14–21 days
Anthurium14–20 days
Protea~8 days (up to 2.5 weeks)
Craspedia 14+ days (dries well, holds even longer)
Hellebore 5–10 days (needs conditioning — see note below)
Foliage: Foliage generally outlasts blooms by a wide margin — Italian pittosporum, gardenia leaf, and monstera leaf will often stay fresh 10–14+ days, even after the blooms in the same arrangement have faded. Many people keep the greenery going in a fresh vase after pulling spent blooms.
A Note on Hellebore: Unlike most blooms on this list, hellebore won't take up water well straight from the cut — it needs to be conditioned first (a brief sear of the stem end in boiling water, or a long, deep drink overnight) before it'll hold in a vase. Skipping this step is the most common reason hellebore wilts within hours instead of lasting the better part of a week.
