Avoid heat and direct sunlight.
Direct light and heat can encourage bacterial growth and shortens the vase-life of your purchased flowers.
Provide plenty of fresh and clean water.
Fresh flower stems are more ‘open’ and less clogged. You’ll see that your fresh flowers will drink a lot of water. Try to change the water in the vase every day.
Remove any leaves below the water level.
Be sure to remove any leaves from the water. Leaves release bacteria and will shorten the vase life of your flowers.
Feed your flowers.
Locally-grown flowers benefit from flower food. This can help extend the vase life of your bouquet. It works best on fresh cut flowers, but can still provide a ‘boost’ a few days later. Just give the stems a slight trim every day or two to keep them open and drinking.
Run out of flower food? Make your own at home with 1 quart of water, 2 tablespoons lemon juice and 1 tablespoon of sugar.
