What technique is used to prolong the life of floral arrangements?

The technique that is effective in prolonging the life of floral arrangements is regularly changing the water and adding flower food. Fresh water is essential for cut flowers, as it helps to keep them hydrated and nourished. Over time, water can become contaminated with bacteria, which can clog the stems and hinder water uptake. By changing the water frequently and adding flower food, which contains nutrients and anti-bacterial agents, the longevity and overall health of the flowers can be significantly enhanced.

Regular maintenance of the arrangement, such as trimming the stems and removing any wilting foliage, also contributes positively. This practice allows the flowers to absorb water more efficiently and stay vibrant longer, making it the most effective approach among the listed techniques.
