What is one consequence of flower stems sealing to the bottom of a container?

When flower stems seal to the bottom of a container, it creates a barrier that inhibits the stems' ability to draw water effectively. This sealing can occur for several reasons, such as a buildup of sap or resin in the stem's end after cutting, or if the stem is placed in a very narrow opening where it fits snugly against the sides.

Water absorption is critical for flowers since they require it to remain turgid and to facilitate nutrient transport throughout their structure. If the stems cannot absorb water properly due to being sealed or blocked at the bottom, the flowers may wilt, deteriorate more quickly, and can significantly reduce their lifespan in the arrangement. This highlights the importance of properly preparing stems before placing them in a container to ensure they can take up water efficiently.
