Understanding the Science Behind Why Flowers Die in a Vase
Introduction:
Freshly cut flowers are a sight to behold, bringing vibrant colours and natural beauty into our homes. However, it’s a common disappointment when these flowers start to wilt and fade away far sooner than we’d like. Have you ever wondered why this happens? In this article, we’ll delve into the science behind why flowers die in a vase and explore some tips to prolong their freshness.
The Role of Water:
Water is essential for the survival of cut flowers, just as it is for plants in the ground. When flowers are cut, they lose their connection to their root system, which is responsible for delivering water and nutrients. Placing them in a vase filled with water is meant to compensate for this loss. However, water alone is not enough to keep flowers fresh indefinitely.
Lack of nutrients:
In addition to water, plants need essential nutrients like sugars and minerals to thrive. When flowers are cut, they lose their ability to absorb nutrients from the soil. While vase water can provide hydration, it lacks the vital nutrients that flowers need to maintain their freshness over time. As a result, flowers gradually deteriorate and wilt.
Bacterial Growth:
One of the main culprits behind wilting flowers is bacterial growth in the vase water. When flowers are cut, their stems are exposed, creating an entry point for bacteria. These bacteria multiply rapidly in the warm, nutrient-rich environment of the vase water, clogging the flower’s vascular system and hindering water uptake. As a result, the flowers lose their ability to absorb water and nutrients, leading to premature wilting.
Ethylene Gas:
Ethylene gas is a natural plant hormone that regulates various physiological processes, including ripening and senescence. Many fruits, such as apples and bananas, produce ethylene gas as they ripen. Unfortunately, the ethylene gas can also accelerate the ageing process of flowers, causing them to wilt and deteriorate more quickly. Exposure to ethylene gas, either from nearby fruits or from internal production by the flowers themselves, can significantly reduce their vase life.
Environmental Factors:
Environmental factors such as temperature, humidity, and light exposure can also impact the longevity of cut flowers. For example, placing flowers in direct sunlight or near heat sources can cause them to wilt more rapidly due to excessive transpiration. Similarly, low humidity levels can accelerate water loss from the flowers, leading to dehydration and wilting.
Conclusion:
While it’s inevitable that cut flowers will eventually wilt and fade away, understanding the factors that contribute to their demise can help us prolong their freshness and enjoyment. By providing clean water, ensuring proper nutrient uptake, minimising bacterial growth, and mitigating exposure to ethylene gas and adverse environmental conditions, we can extend the vase life of our flowers and continue to admire their beauty for as long as possible. So the next time you arrange a bouquet, remember these tips to keep your flowers looking fresh and vibrant for days to come.
5 Proven Tips to Keep Your Flowers Fresh in a Vase Longer
Start with a clean vase:
Before placing your flowers in a vase, ensure it’s clean and free from any bacteria or residue. Wash the vase thoroughly with hot, soapy water, and rinse it well. This simple step helps prevent bacterial growth in the water, keeping your flowers healthier for longer.
Trim the stems:
When you receive or purchase flowers, they’ve likely been out of water for some time. To ensure optimal water uptake, trim the stems at a 45-degree angle with sharp scissors or a knife. This increases the surface area for water absorption and removes any damaged or blocked sections, allowing the flowers to hydrate more effectively.
Use flower food:
Flower food packets, often provided with store-bought bouquets, contain essential nutrients and additives that nourish the flowers and inhibit bacterial growth. Dissolve the flower food in the vase water according to the package instructions before placing your flowers. You can buy flowers/plant food here;

Change the water regularly:
To prevent the buildup of bacteria and algae in the vase water, change it every two to three days or whenever it appears cloudy or discoloured. Before adding fresh water, rinse the vase thoroughly to remove any residue. Additionally, recut the stems at a slight angle to maintain their ability to absorb water efficiently.
Keep them cool and hydrated:
Flowers are sensitive to environmental factors such as heat and humidity, which can accelerate wilting. To prolong their freshness, place your floral arrangement in a cool spot away from direct sunlight, heating vents, and drafts. If possible, use a vase with a narrow opening to support the stems and keep them upright. Additionally, misting the petals with water or placing the vase on a tray filled with water and pebbles can help increase humidity and prevent dehydration.
With these five simple yet effective tips, you can enjoy the beauty of your flowers for much longer.
