What factors are essential for plant health in a floral setting?

For plant health in a floral setting, the crucial factors include temperature, light, and watering. These elements directly influence a plant's growth, development, and overall vitality.

Temperature plays a significant role in the metabolic processes of plants. Each plant species has an optimal temperature range that allows for proper growth and flowering. Extreme temperatures, either too high or too low, can stress the plant, leading to poor health or even death.

Light is essential for photosynthesis, the process by which plants convert light energy into chemical energy. Sufficient and appropriate light exposure ensures that plants can produce the food they need to thrive. Additionally, the quality and duration of light can affect blooming times and the vigor of the flowers.

Watering is critical as well because it provides hydration and helps transport nutrients throughout the plant. Overwatering or underwatering can lead to root rot or dehydration, respectively, both of which are detrimental to plant health.

The other options focus on aspects that, while related to floral design and aesthetics, do not have a direct impact on the health of the plants themselves. Using a specific type of vase might enhance visual appeal but does not substitute for the vital environmental conditions that the plants require to survive and flourish. Thus, temperature, light, and watering are
