You should regularly check and maintain your flowers so that they always look good.
Check Flowers Regularly
You should have the vase or containers with fresh water. Even if the container has floral foam, you should maintain the water level so that the flowers last longer. The container's water has fresh flower food added to it. If you change the water, you should clean the container properly. Also add the fresh water with commercial fresh flower food. The flower foods are available with florists.
While a flower is attached to the plant, it receives nourishment allowing it to grow and develop. When cut from the plant, it loses its source of nourishment and water. Fresh Flower Food was developed to simulate the flower's original environment, and allow the flower to fully develop (open).
The key functions of a fresh flower food are:
Provides food in the form of sugars to keep the flowers alive, flowers use carbohydrates as an energy source.
Helps lower the pH, which keeps the water/food conducting system in flowers working at maximum efficiency.
Keep bacteria in control so that the stems are not blocked and water absorption happens properly
Homemade versions such as copper pennies in the water, aspirin, soda, etc., do not contain all of the necessary ingredients vital to sustaining flower life. For the most part, they are ineffective and end up costing you more than fresh flower food.
Every few days, remove the flowers from the design and re-cut the stems. Remove three-fourth to one inch from the bottom of the stem and cut the stem at the angle so that the flower can take up water properly. Use a sharp knofe or scissors. Avoid smashing or piercing the stems as this can destroy the water vessels in the stem.Remove any damaged blooms or foliage that falls below the waterline in the vase. To avoid disturbing the stem placements in the vase arrangement, tie the stems with twine-bound point to the re-cut the stems. Then place them back into the clean vase with fresh water and flower food.
The flowers are best displayed in particular temperature ranges. They are best displayed away from direct sunlight, heating or cooling vents, under ceiling fans, or on top of televisions or computers or appliances that get heated. Avoid putting flowers near fruits as they release tiny amounts of ethylene that can cause fruits to ripe prematurely.
