FFA Floriculture Practice Test

Which of the following is a common preservation method for flowers?

1. Drying with light

2. Refrigeration

3. Silica gel, sand, or glycerin

4. Pesticide application

The correct answer is: Silica gel, sand, or glycerin

Using silica gel, sand, or glycerin is a common preservation method for flowers. These materials effectively remove moisture from the flowers, helping to maintain their color and structure while preventing decay. Silica gel absorbs moisture quickly and is popular for preserving the natural appearance of flowers, allowing them to retain their shape and vibrancy. Glycerin can be used to hydrate the stems of certain types of foliage, resulting in flexible and soft leaves, while sand can also serve as a medium to support the flowers as they dry. Other options are not ideal preservation methods. Drying with light can lead to fading and loss of color, which is not desirable when preserving flowers. Refrigeration may extend the life of fresh flowers temporarily but is not a long-term preservation method. Pesticide application is meant for protecting flowers from pests and diseases, not for preservation, and could even be harmful if not managed properly. Therefore, silica gel, sand, or glycerin is widely regarded as the most effective preservation technique for maintaining the quality and beauty of dried flowers.
