What floral arrangement technique helps to extend the life of corsages?

To extend the life of corsages, employing proper hydrating techniques before assembly is essential. This technique involves adequately watering the flowers and allowing them to absorb moisture before being arranged into the corsage. Hydration is key because cut flowers lose water through transpiration once they are removed from their source. By ensuring that the flowers are well-hydrated prior to assembly, they can better withstand the stresses of being transported and worn, leading to a fresher appearance and a longer life when worn as a corsage.

The other options do not contribute positively to the longevity of a corsage. Incorporating wilted flowers would introduce decay and negatively impact the overall look and freshness of the arrangement. Using low-quality water could introduce contaminants or minerals that could harm the flowers, rather than support their hydration. Creating an airtight seal would actually restrict airflow and moisture exchange, which are crucial for the flowers' health. Thus, ensuring that flowers are properly hydrated before assembling the corsage is the most effective method for extending its life.
