What is the conditioning requirement for foliage from ginger, canna, and caladium?

The conditioning requirement for foliage from ginger, canna, and caladium involves submerging them in water. This process helps to hydrate the foliage, ensuring that it remains fresh and vibrant. Foliage from these plants can initially have a waxy coating that makes it difficult for them to absorb water through their stems. By submerging the entire stem or the leaves in water, you facilitate the uptake of moisture throughout the plant material, which is crucial for maintaining their quality in arrangements.

This hydration method helps to prevent wilting and ensures longevity in floral designs. The other conditioning methods such as crushing, searing, or providing high humidity may not be suitable or necessary for these specific types of foliage, as they have unique characteristics that respond best to hydration through submersion.
