You probably already know the trick of putting an aspirin in flower water to keep them fresh longer.
But according to a study from the University of Rhode Island (USA), acetylsalicylic acid , i.e. aspirin , is not only useful for cut plants, but can also strengthen their immune system by making them grow bigger and stronger .
The researchers dissolved 4 aspirin tablets in 4 liters of water and sprayed the solution on a group of plants every 3 weeks. At the end of the season the plants treated with aspirin had grown stronger and more vigorous as they were more resistant to microorganisms and fungi.
This treatment has proven to be even more effective on nocturnal plant crops such as potatoes and tomatoes.
There are several ways to harness the power of aspirin for plants , and we’ve listed the best ones below.
As a rooting agent : soak the cuttings for 3-4 hours in distilled water with 1 aspirin. It has a disinfectant effect, protects cuttings from mold and activates growth.
As a growth accelerator : dilute 1 aspirin in a liter of water and spray the solution on the plants every 3 weeks. Do not exaggerate with the quantities because the plant could suffer.
To germinate seeds : Soak the seeds in a solution of water and aspirin before planting.
On the ground : To avoid diluting the aspirin, you can place the tablets directly in the soil, about 15 cm from the plant, and then water regularly.
