What effect does proper flower care have on an arrangement?

Proper flower care significantly prolongs the freshness of flowers, which is crucial for maintaining the visual appeal and longevity of an arrangement. Fresh flowers are essential for any floral design, as they not only look vibrant and healthy but also last longer, allowing customers to enjoy the arrangement for days or even weeks. Adequate care includes practices such as providing the right amount of water, using clean tools and containers, maintaining a suitable temperature, and ensuring that flowers are free from any harmful bacteria.

While the other options might seem plausible in different contexts—such as changing colors through specific techniques or impacting costs—none align with the critical role that longevity plays in enhancing the overall quality and enjoyment of floral arrangements. Proper care ensures that flowers remain at their best for extended periods, which is crucial for both the florist's reputation and customer satisfaction.
