What should a florist do if they notice some flowers are wilting during preparation?

When a florist notices that some flowers are wilting during preparation, the best course of action is to replace them with fresh flowers. Wilting is a sign that the flowers are not in optimal condition and may not last well in a corsage or boutonniere. Using wilted flowers can detract from the overall appearance of the arrangement, leading to an unsatisfactory outcome for the client.

Replacing wilting flowers ensures that the final product is vibrant and fresh, which is crucial for special occasions like proms or weddings where the bouquet or boutonniere will be prominently displayed. Fresh flowers not only enhance the aesthetic quality but also improve the longevity of the arrangement, which is important for the event.

The other options involve ignoring the potential issues with the wilted flowers, which could result in a less desirable product. Continuing preparation with wilted flowers or using them for practice does not address their compromised condition, while just spraying them with water may temporarily perk them up but does not address the underlying problem of deterioration.
