Which is a common technique for preserving cut flowers?

Drying or pressing is a common technique for preserving cut flowers, enabling them to maintain their shape and color over time. This method involves removing moisture from the flowers, which helps to prevent decay and preserves their appearance for long periods. When flowers are dried, they can be displayed as decorative items or used in crafts without the need for water, making them versatile for various arrangements and uses.

While other techniques may be used to extend the life of cut flowers temporarily, they do not serve the same purpose as drying or pressing. Refrigeration can slow down the wilting process but is generally a short-term solution. Submerging in water is standard practice for keeping flowers fresh, but it does not preserve them for long-term use like drying or pressing does. Painting flowers may enhance their appearance, but it doesn't effectively preserve them. Therefore, drying or pressing is recognized for its ability to retain the beauty of cut flowers over an extended period.
