Flowering plants, just like any other living organism on this planet, need nutrients and certain minerals in order to grow and be able to survive. In the case of plants, the nutrients needed for their survival mainly come from the soil and pass through its root system. While plants need a lot of nutrients, some of their most basic necessities include phosphorus, potassium and nitrogen.
When a flower is cut from its mother plant, it is extremely severed from its main nutrient supply. Thus, the flower will no longer receive the nutrients and the essential minerals which it needs in order to continue to survive. After being detached from its source of important nutrients, the flower will then die after a short period of time.
Aside from the essential nutrients that plants obtain from the soil, other elements such as carbon dioxide, sunlight and water, are equally necessary for its survival. These factors act together in order to carry out a process called photosynthesis. This process is responsible for producing sugar which is another vital element for the growth, development and survival of plants.
When flowers are detached from the plant by cutting them, they will no longer obtain the benefits brought about by photosynthesis. Now being disconnected from the intricate system that sustains their life, thereby, their life span is shortened tremendously.
When put in a vase, or in any container with water, microorganisms will tend to multiply in the container or on the flower itself. This build up of microorganisms will make the water slimy and will unfortunately block the flower’s water absorption. This excessive water loss will cause the cells of the flowers to burst. And considering the fact that water is very essential for cellular functions, its absence will cause the cells to eventually die and as a result, the entire flower will wither as well.
