How to Use This Calculator

How the result changes with Room temperature (°F)

Flower type: 0=Chrysanthemum, 1=Carnation, 2=Alstroemeria, 3=Rose, 4=Lily, 5=Tulip, 6=Gerbera, 7=Peony.
Number of stems: Total stems in your arrangement.
Room temperature (°F): Average temperature where flowers are displayed. Cooler = longer life.
Using flower food?: 1 = Yes, 0 = No. Commercial flower food extends life 40–60%.
Water change frequency (days): How often you change the water. Every 2 days is optimal.
Re-cut stems?: 1 = Yes, 0 = No. Cut 1 inch off stems at 45° angle when changing water.
Direct sunlight?: 1 = Yes, 0 = No. Direct sun accelerates wilting.
Near ripening fruit?: 1 = Yes, 0 = No. Fruit emits ethylene gas that kills flowers.

Expected vase life (days): Estimated days your flowers will last with current care.
Base vase life (days): Typical vase life for this flower type under good conditions.
Days lost to conditions: Days of life lost due to suboptimal care conditions.
Water per change (cups): Recommended fresh water volume per water change.
Flower food packets: Flower food packets needed (1 per quart of water).
Total water changes: Number of water changes over the flower's expected life.
Optimal display temp (°F): Ideal room temperature for maximum vase life.
