I spent four years conditioning flowers at a wholesale house before I ever designed an arrangement. Which means I watched a lot of flowers die — and learned exactly why. Most cut flowers last 5 days because of very preventable mistakes. Here's how to get to two weeks.
1. Cut the stems before they hit the water. This is the single most important thing you can do. Cut at a 45-degree angle with a sharp knife or scissors, under running water or immediately before dropping into the vase. The angled cut increases surface area and prevents the stem from sitting flat against the bottom of the vase and blocking water uptake. Do this every 2–3 days when you change the water.
2. Remove every leaf that falls below the waterline. Leaves in water decompose. Decomposing leaves introduce bacteria into the water at a rate that dramatically shortens flower life. Strip every leaf that would sit below the water surface before you arrange.
3. Use clean water and a clean vase. Bacteria from a dirty vase will kill flowers faster than almost anything else. Wash your vase with dish soap between arrangements. Change the water every 2 days.
4. Keep flowers away from these four things: direct sunlight, heating vents, drafts, and ripening fruit. The ethylene gas that fruit emits as it ripens accelerates flower death significantly. A banana on the counter next to your bouquet is cutting your flower life in half.
5. Use the flower food packet. We include one with every arrangement. It's not gimmicky — it contains bactericide, an acidifier that helps water uptake, and a sugar source that feeds the flowers. Use it. If you lose it, a drop of bleach and a teaspoon of sugar per quart of water approximates the formula.
6. At night, move arrangements to a cool spot. Flowers last longer at lower temperatures. If you have space in the garage or a cool hallway, moving your arrangement there overnight makes a real difference. Florists store flowers in coolers at 35–38°F for a reason.
7. For roses specifically: if they start wilting, try a hot-water revival. Cut the stems, then place just the bottom inch of the stem in very hot (not boiling) water for 30 seconds before transferring to a clean vase of cool water. It can revive wilted roses remarkably well. I've saved arrangements I thought were done with this trick.
