The Short Answer
To keep a wildflower bouquet fresh for 7–10 days: re-trim stems at a 45° angle every two days, change the water completely (don't just top up), strip any leaves below the waterline, keep the vase cool and out of direct sunlight, and pull individual stems as they fade so the rest last longer.
1. Trim, and keep trimming
The single biggest factor in vase life is the cut. Stems seal over within hours of being out of water, so re-trim about a centimetre off each stem at a 45° angle when your bouquet arrives — and again every couple of days. The angled cut increases the surface area drinking water and stops the stem sitting flat against the vase bottom.
2. Change the water — don't top it up
Cloudy water is bacteria, and bacteria clog stems. Every two days, empty the vase completely, rinse it, and refill with cool fresh water. This one habit alone typically adds three to four days of life to a mixed wildflower arrangement.
3. Nothing below the waterline
Leaves and greenery submerged in water rot fast and poison the vase. Strip anything that would sit below the waterline. Wildflower arrangements are texture-heavy — grasses, herbs, foliage — so this matters more for our style than for a dozen roses.
4. Location, location
Keep the vase away from direct sun, heat vents, and the fruit bowl (ripening fruit releases ethylene gas, which ages flowers). A cool corner with bright indirect light is the sweet spot. Ontario summers get warm — on hot days, a cooler room buys real time.
5. Edit as you go
Mixed arrangements age at mixed speeds — cosmos might bow out before the grasses even think about it. Pull individual fading stems promptly rather than waiting for the whole bouquet to turn. A wildflower arrangement often gets looser and lovelier in its second week as it settles.

Frequently Asked Questions
How long should a wildflower bouquet last?
With proper care — regular trims, fresh water every two days, and a cool spot out of direct sun — a hand-tied wildflower bouquet typically lasts 7–10 days, with some hardy stems going longer.
Should I use flower food with wildflowers?
Flower food helps, but clean water changed every two days matters more. If you use the sachet, still do the full water changes — food isn't a substitute for fresh water.
Why are some stems fading faster than others?
Mixed wildflower arrangements combine varieties with different vase lives. Pull faded stems as they go — the bouquet is designed to evolve, and often looks beautifully loose in week two.
