Sugar water is a popular way to preserve flowers, but it's not actually effective at doing so. The reason why sugar water doesn't work as a flower preserver is because it doesn't have the right balance of chemicals and minerals to keep flowers healthy and fresh. Flowers need specific nutrients to stay alive and fresh. This absorbed water can cause damage to the plant's cells and leaves, making them moist and unhealthy. Most people believe that sugar water is an effective flower preserver because it keeps flowers hydrated and looking fresh. However, this is not actually the case. This can cause your flowers to wilt, turn brown and eventually die. In fact, sugar water is even worse than vinegar in terms of how it affects plant growth, but this practice has not been found to be effective in the long run. Instead of using sugar water as a flower preserver, try one of the many other popular methods such as hydroponics or cold frames. These techniques allow your plants access to natural sunlight and humidity which helps them retain moisture and nutrients while preventing pests from destroying your flowers. Many commercial flower preservation products contain harsh chemicals that can damage plant cells and kill off beneficial bacteria.
