What is the difference between "flower food" and "plant food"?

The distinction between flower food and plant food lies primarily in their intended uses and formulations. Flower food is specifically designed for cut flowers. It typically contains a mix of sugar to provide energy, as well as acids and biocides to help prolong the life of the flowers by preventing bacterial growth and maintaining the right pH balance in the water. This helps to keep cut flowers fresher for a longer period when placed in a vase.

On the other hand, plant food is formulated for potted or garden plants, providing essential nutrients that support overall plant health, including growth, foliage, and blooming. Its composition is tailored to enhance the plants' nutritional needs rather than to prolong the life of cut flowers.

The other statements do not accurately capture the main differences. For instance, while plant food can influence flower color indirectly by impacting overall plant health, it does not serve the same immediate purpose as flower food. Similarly, flower food is not designated for outdoor gardens and is not simply a high-sugar solution, as its effectiveness relies on a balanced mix of ingredients tailored to cut flowers.
