Use the packets of fresh cut flower food available from your florist or which is included in your readymade bouquet. We love the brand Chrysal Cut Flower Food because it dissolves and disappears in the water! It provides the nutrients your flowers need (potassium, phosphorus and nitrogen) for longevity and also contains antibacterial properties to help keep the water clean. It also has a water softening agent that helps your flowers drink.

Water ‑to-Food Ratio: Proper Mix
Always dissolve flower food in water according to the packet instructions. Most small packets are formulated for 2 cups (16 oz) of water.
It might be tempting to add extra packet powder thinking it will help, but using flower food in higher concentrations can actually harm your flowers! Excessive flower food alters the osmotic balance, causing water and vital nutrients to be drawn out of the stems into the solution rather than absorbed.
Water Temperature Tips for Cut Flowers
Matching the water temperature to the current temperature of your blooms prevents temperature shock:
Cool Water: Best for flowers coming directly out of a cooler or refrigeration.
Tepid/Room Temperature Water: Best for stems harvested from a warm garden or kept at room temperature. Avoid icy cold water for warm blooms, as sudden temperature swings prevent effective hydration.
Daily Care and Maintenance Beyond Flower Food
To keep your bouquet fresh for a week or longer, pair proper floral food with basic routine care:
- Re-cut Stems: Every 2–3 days, trim about half an inch off the bottom of each stem at a 45-degree angle using sharp, clean floral shears.
- Keep Water Clean: If the vase water becomes cloudy or discolored, empty it, clean the container, and replace it with a fresh batch of water and cut flower food.
- Placement Matters: Keep your arrangement away from direct sunlight, heating vents, drafty windows, and ripening fruit (which releases ethylene gas that accelerates wilting).
