Cut-flower bench reference

The short answer

How long do cut flowers last in a vase, and what do I have to do in the first hour to make them last longer?

Most cut flowers hold for 5 to 10 days at room temperature, and a handful of species go well beyond that. The single biggest lever you control is the first hour after you get them home: recutting every stem underwater at a 45-degree angle, into clean water with the right preservative, before the cut surface has a chance to seal shut.

Skip that hour and a rose bought with 7 days of life left can drop its head by day 3. Get it right and the same rose reaches the top of its range. The table below is the number to check before you buy; the procedure after it is the number you control once you get home.

What to do with this page

  • Look up the realistic vase life of a species before buying it.
  • Condition cut stems correctly in the first hour to extend that vase life.
  • Keep a vase alive day by day with the right water, temperature and preservative.
  • Choose the longest-lasting species for a bouquet that must survive a gift delivery.
  • Diagnose a wilting bouquet and tell wilting from stem blockage.

Typical vase life at room temperature

Days a stem stays presentable at 18–21°C, by species
Species Vase life Notes
Roses 5–7 days Most common gift bouquet stem
Tulips 5–7 days Ethylene-sensitive, keep from fruit
Carnations 7–10 days Ethylene-sensitive
Gerbera 7–10 days Hollow stem, recut cleanly
Lilies 7–10 days Ethylene-sensitive
Chrysanthemums 10–14 days Reliable for events
Sunflowers 5–7 days Heavy head, drinks fast
Phalaenopsis spikes 14–28 days Longest-lasting cut stem here

The first hour

Condition the stems before they sit anywhere

This is the procedure that buys back the days lost to a warm delivery van and a dry shop floor. Do it before the bouquet goes on a table, not after it starts to droop.

  1. Unwrap and strip lower foliage0–5 min Remove any leaf that will sit below the waterline. Typical failure: leaves left on submerged stems rot and cloud the water within 48 hours.
  2. Recut every stem underwater5–15 min Cut at a 45-degree angle, losing 1–2 cm, with the cut end submerged. Typical failure: a flat cut made in air seals against the vase wall and blocks water uptake within hours.
  3. Fill the vase to the right depth15–20 min Use roughly 1–2 litres of clean water for a 10-stem bunch, enough to sit below the foliage line. Typical failure: too little water and the stems run dry overnight; too much and submerged foliage sits in it.
  4. Add preservative to the water20–25 min Commercial flower food (20–50 g sugar per litre plus acidifier, pH 3.5–5.0) or a home substitute of 1–2 teaspoons of household bleach per 4 litres. Typical failure: sugar added without an acidifier feeds bacteria instead of the flower.
  5. Place away from heat, sun and fruit25–40 min Keep the vase in an 18–21°C room, out of direct sun, and away from a fruit bowl. Typical failure: ethylene gas from ripening fruit drops petals within 24–48 hours.
  6. Check the water level in the first 24 hoursHour 24 A 500 g bunch can take up to 5% of its weight in water, roughly 25 ml per stem per day, so top up early. Typical failure: a vase that looks full at hour one runs dry by hour twenty, since uptake peaks in the first day.

Questions we actually get

Frequently asked

Do I really need to recut the stems if the florist already cut them?

Yes. Every minute a cut stem spends out of water, air is drawn into the tissue and the cut surface starts to seal, which is exactly what blocks uptake within hours. The florist's cut happened before transport; you need a fresh one after it, underwater, in your own kitchen.

Can I just use sugar and skip the flower food packet?

No. Sugar alone (20–50 g per litre is the commercial dose) feeds bacteria as readily as it feeds the stem. The packet's acidifier drops the water to pH 3.5–5.0, which is what lets the stem actually take the sugar up quickly. Sugar without the acid just grows slime faster.

Is tap water fine, or does it need to be distilled?

Tap water is fine. What matters is that it is clean and changed every 2 days, that the vase is washed with detergent at each change, and that no submerged leaf is left to rot. Cleanliness matters far more than mineral content.

My bouquet wilted overnight. Is it the flowers or something I did?

Check the stem ends first. If they feel soft, dark or slimy, it is bacterial blockage from water that went unchanged or foliage left underwater. If the stems feel firm and pale, the flowers are simply thirsty or exposed to ethylene, heat or direct sun. See the troubleshooting table on the daily care page.

Will putting the vase in the fridge overnight actually help?

Yes, measurably. A cool 4–8°C night in a domestic fridge can extend a bouquet by 2–4 days, on top of the gain from keeping the room itself at 18–21°C instead of a warm 25°C shelf.
