What is the typical method used to keep water in floral arrangements?

The typical method used to keep water in floral arrangements is floral foam. This material, often known as oasis foam, is specifically designed to absorb and retain water, providing a hydrated environment for the flowers. When flowers are inserted into floral foam, they are not only secured in place but also have a consistent source of hydration, which is crucial for maintaining their freshness and longevity.

In contrast, while glass vases can hold water and are commonly used in arrangements, they do not provide the same stability and hydration control that floral foam does. Plastic wrap is not intended for this purpose, as it does not retain water effectively for flower hydration. Water tubes are often used for individual stem hydration, particularly when flowers are transported, but they do not encompass the entire arrangement as floral foam does.

Floral foam is favored by florists because of its ability to support creative arrangements in various shapes and sizes while ensuring that the flowers receive the necessary moisture to thrive.
