How Long Should Cut Flowers Last? Tips from Flowers by Zak, Mornington Florist

At Flowers by Zak, we want your blooms to look beautiful for as long as possible. With the right care, most cut flowers should last 5–10 days, and many hardy varieties will go well beyond that. Here’s what to expect, why flowers sometimes fail, and how to keep your vase looking fresh all week on the Mornington Peninsula.

What’s a normal vase life?

- 3–5 days: Tulips, poppies, sweet peas, hydrangea in warm rooms

- 5–7 days: Standard roses, sunflowers, gerberas

- 7–10 days: Asiatic/Oriental lilies, chrysanthemums, lisianthus

- 10–14+ days: Alstroemeria (Peruvian lily), disbuds, natives (proteas, banksias), orchids (phalaenopsis/cymbidium)

- 14–21 days: Carnations, chrysanthemums, tropicals and many natives with woody stems

Long-lasting favourites we love

- Alstroemeria: Loads of buds that open in sequence; minimal shedding.

- Chrysanthemums and disbuds: Reliable, full-headed, and tough.

- Carnations: Classic and incredibly resilient.

- Orchids: Elegant and long-lived with minimal care.

- Natives (proteas, banksias, leucadendron): Textural, striking, and excellent vase life, especially in our local climate.

Why flowers may fail early

- Dirty vases and bacteria: Microbes block stems, stopping water uptake.

- Warmth and direct sun: Speeds up aging and wilting.

- Ethylene gas: Ripening fruit, exhaust, and smoke produce ethylene, which ages blooms quickly.

- Dehydration in transit: A hot car or long trip without water stresses stems.

- Blocked or crushed stems: Not recutting before placing in water reduces hydration.

- Mixed varieties with conflicting needs: Some stems (e.g., daffodils) release sap that shortens others’ life if not conditioned first.

- Hard water or no food: Poor water quality and lack of nutrients shorten vase life.

How to make your flowers last longer

- Start spotless: Wash your vase with hot soapy water and a splash of bleach, rinse thoroughly.

- Fresh cut: Trim 1–2 cm off stems at a sharp angle under running water or in a bowl to prevent air blockages. Recut every 2–3 days.

- Use flower food: Half a teaspoon of sugar and a few drops of bleach is all you need. It nourishes blooms and reduces bacteria.

- Cool placement: Keep out of direct sun, away from heaters, fireplaces, and drafts.

- Change water often: Every 2 days (daily in hot weather). Top up between changes.

- Strip lower leaves: No foliage below the waterline—this is where bacteria thrive.

- Avoid fruit bowls: Keep arrangements away from bananas, apples, and other ripening fruit.

- Support heavy heads: For gerberas and sunflowers, shallow water (3–5 cm) helps reduce stem rot; lilies prefer deeper water.

- Mind the Mornington heat: In summer, never leave flowers in a hot car and rehydrate promptly when home.
