How to Preserve you Flowers March 7, 2017 16:15
Using a preservative definitely increases the longevity of cut flowers. To survive, flowers need three ingredients: carbohydrates, biocides, and acidifiers. Carbohydrates are necessary for cell metabolism; biocides combat bacteria and are necessary for maintaining plant health; acidifiers adjust the pH of water to facilitate and increase water uptake.
Homemade Flower Preservative
Home mixes can be as effective as commercial preservatives. This easy-to-make recipe is my favourite.
- 1 teaspoon sugar
- 1 teaspoon household bleach
- 2 teaspoons lemon or lime juice
- 1 quart lukewarm water
Under normal circumstances, flowers get what they need from the plant. When severed from the plant, however, flowers are deprived of these essential substances. But they are present in ready-made commercial preservatives, like Floral Life. Such solutions contain sugar for nutrition, bleach to keep the water clear of bacteria, and citric acid to gently acidify the water. When using commercial brands, be sure to follow recommended measurements for different container sizes.
One common suggestion is to place an aspirin in the water to keep flowers fresh. It is likely that aspirin's effectiveness is simply the result of the drug's carbohydrate content. Another well-known suggestion is to drop a penny into the water. Apparently, the copper in the penny works like an acidifier, decreasing the pH of the water. Unfortunately, solid copper pennies are no longer being minted.
