Many flower growers and florists resort to an unusual method of prolonging the life of cut flowers - adding aspirin to the water.
What benefits does this medicine bring to plants?
Mechanism of action of aspirin on flowers
Acetylsalicylic acid, known as aspirin, has properties that are beneficial to cut flowers.
When aspirin gets into water, it reduces its acidity, which prevents the growth of bacteria.
Bacteria are the main enemies of flower freshness; they clog the stem vessels, preventing the flow of water and nutrients.
In addition, aspirin stimulates the production of ethylene in plants, a hormone responsible for the aging process.
Paradoxically, a small amount of ethylene makes the plant "resist" aging by activating protective mechanisms.
Proper Use of Aspirin for Flowers
To achieve the best effect, it is important to use aspirin correctly. The optimal dosage is one tablet (325 mg) per liter of water.
The tablet should be dissolved in a small amount of warm water and then added to a vase of cool water.
Before adding flowers to the solution, it is necessary to refresh the cut on the stems. A 45-degree cut increases the surface area through which the flowers receive water.
Leaves below the water level should be removed to prevent rotting.
The Effect of Aspirin on Different Types of Flowers
Aspirin is effective for most cut flowers, but some species respond particularly well to it.
Roses, chrysanthemums, carnations and lilies show a noticeable increase in freshness when using aspirin solution. However, for some species, such as tulips, aspirin may be ineffective or even harmful.
Alternative ways to extend the life of cut flowers
Besides aspirin, there are other folk methods for keeping bouquets fresh. Adding a small amount of sugar to the water (1 teaspoon per liter) provides the flowers with additional nutrition. A drop of bleach or vodka in the water also helps fight bacteria.
Professional florists often use special preservatives for cut flowers, which contain a complex of substances that prolong the life of plants. These products are usually more effective than home methods, but they are also more expensive.
Precautions when using aspirin
Despite the effectiveness of aspirin, it is important to remember some precautions. An overdose of aspirin can harm the flowers, causing them to wilt quickly. The solution should be changed every 2-3 days, preparing a fresh portion.
It is also worth considering that aspirin is not a panacea. It cannot compensate for improper storage conditions of flowers. It is important to keep the bouquet away from direct sunlight, drafts and heat sources.
Scientific evidence for the effectiveness of aspirin
Research confirms the positive effect of aspirin on cut flowers. Experiments have shown that flowers in aspirin solution stay fresh for 1-3 days longer than in plain water.
However, effectiveness depends on many factors, including the type of flowers, their original condition and storage conditions.
Using Aspirin for Houseplants
Interestingly, aspirin can be useful not only for cut flowers, but also for indoor plants.
An aspirin solution applied as a top dressing once a month helps to strengthen the immunity of plants and increase their resistance to diseases.
