Ever harvested a flower at its most perfect moment… only to find it drooping in the vase the next day? You're not alone. When it comes to cut flowers, timing really is everything — and the way you condition each stem can make the difference between three days of beauty or a full ten-day display.
Whether you’re a home grower hoping to keep that sweet pea scent lingering longer, or a florist trying to get dahlias to behave in a bridal bouquet — this flower vase Life & conditioning guide is your backstage pass to vase life success.
🎧 Prefer to listen?
This blog was inspired by Episode 23 of The Blooming Garden Podcast — where I walk you through everything from timing your cuts to searing stems and avoiding floppy cosmos. It’s packed with practical tips (plus a few floral horror stories), and it’s ideal for listening while sowing your next tray of snapdragons.
Why Flower Vase Life & Conditioning Matters
The moment you cut a flower, the clock starts ticking. Each stem has different needs: some like a long, cool drink, others prefer a quick sear or a bit of bleach in the water. Pick too early and they won’t open. Pick too late and they’ll wilt before the wrapping paper’s even off.
Get it right, and you’ll not only extend the life of your flowers — you’ll also unlock their full colour, shape, and scent potential.

Here’s a little taster:
Ranunculus: Harvest when soft like a marshmallow. Too tight? They’ll never open.
Tulips: Wrap tight in paper and store with the bulb on for laser-straight stems.
Cornflowers: Pick when the first buds are opening — the rest will catch up in the vase.
Dahlias: They won’t open after cutting. Harvest nearly open and check the backs for browning.
Zinnias: Wiggle test! If the stem flops, it’s not ready.
