Simple steps that actually work — the same ones we use in the studio every day. No special products needed.
Do these five things and your flowers will last noticeably longer. Everything else is a bonus.
These ranges assume proper care: fresh water every 1–2 days, trimmed stems, indirect light, room temperature below 22°C. Without care, expect roughly half these lifespans.
Tap water works perfectly fine. The temperature matters more than the type — use lukewarm water, never cold from the tap. Cold water shocks the stems and slows water uptake significantly. Change it every 24–48 hours, not when it looks cloudy. By then the damage is done.
Cut at a 45° angle, never straight across. A diagonal cut creates more surface area for water absorption and prevents the stem from sitting flat on the vase bottom, which would block uptake entirely. Use sharp scissors or a clean knife — crushing the stem with dull scissors restricts water flow.
Flowers last longest in cool, indirect light. Avoid windowsills in direct sun, surfaces near radiators or heating vents, and anywhere that gets above 22°C regularly. A cool room overnight can add 1–2 days to the arrangement — this is why florists store flowers in coolers and why your flowers visibly perk up if you put them in a cool room at night.
A vase that looks clean is often not clean. Bacteria cling to the inside of glass and ceramic even after rinsing with water. Always wash with hot soapy water, rinse thoroughly, and let dry before use. If you're reusing a vase from a previous arrangement, treat it as contaminated — even one day of sitting empty allows bacterial residue to build up.
General care applies to all cut flowers. These are the specific adjustments that make a real difference for each type.
Ripening fruit produces ethylene gas, which triggers the ripening process in cut flowers too. A bowl of apples can cut flower life in half. Keep flowers and fruit in separate rooms.
The most common mistake. Water that looks clear can be heavily contaminated with bacteria after 48 hours. Change it every 1–2 days, not when it looks bad.
A vase that "looks clean" from rinsing with water is not clean. Bacteria cling to glass. Wash with hot soapy water every single time.
A flat cut rests against the vase bottom and blocks water uptake. Always cut at 45° with sharp scissors, and repeat every 2 days.
A sunny windowsill looks like a good spot but accelerates wilting dramatically. Indirect light and cooler rooms extend life by 2–3 days.
Any leaf submerged in water will rot within a day and release bacteria that affects the whole arrangement. Remove all leaves below the waterline immediately.
