How to make grocery store flowers last two weeks

A grocery-store bouquet costs $10. A florist bouquet costs $60. The trick isn't the flowers — it's the five minutes you spend when you get them home. Do this once and the same bunch that used to wilt in four days will still look good on day twelve.

The three things that kill grocery flowers early

1. Sealed stems. Flowers ship dry, and the cut ends seal shut within hours. If you plunk them straight into water they're basically sipping through a closed straw.
2. Bacteria in the vase. Leaves left underwater rot fast, feeding bacteria that clog the stems and turn the water cloudy overnight.
3. Room-temperature tap water. It sounds gentle, but for most flowers (especially tulips and hydrangeas) cool water absorbs faster.

The five-minute florist routine

1. Unwrap the bouquet fully. Compost the paper — it's already damp and hides mold.
2. Fill a clean vase with cool water. Add the little food packet, or use ½ tsp sugar + 1 drop bleach per liter.
3. Strip every leaf that would sit below the waterline. All of them. Bare stem only from the halfway point down.
4. Re-cut each stem at a 45° angle under running water. Cut off at least an inch — the sealed part is longer than you think.
5. Put them in the vase within 60 seconds of cutting so the stems don't seal again.

Then, every two days

• Change the water completely. Not top up — dump and refill.
• Give each stem a fresh half-inch cut.
• Pull out any flower that's clearly done. One rotting bloom sours the whole vase.

Where to put the vase

Away from direct sun, away from the fruit bowl (ripe fruit gives off ethylene, which ages flowers), and away from heating or AC vents. A kitchen counter that gets bright indirect light is perfect.

That's it. Five minutes on day one, two minutes every couple of days, and you'll double the life of every bouquet you ever bring home.
