I’m sure you already know the trick of putting an aspirin in the water of the flowers to keep them fresh for longer.

However, according to a study from the University of Rhode Island (USA), acetylsalicylic acid, i.e. aspirin, is not only helpful with cut plants, but it can improve their immune system by making them grow bigger and stronger.

The researchers dissolved 4 aspirin tablets in 4 liters of water, spraying the solution on a group of plants every 3 weeks. By the end of the season, the aspirin-treated plants had grown larger and were stronger, as they were more resistant to microorganisms and fungi.

This treatment has proven to be even more effective on nightshade plants such as potatoes and tomatoes.

There are several ways to harness the power of aspirin in 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. This action acts as a disinfectant, protecting the cuttings from mold and mildew and activating growth.

As a growth accelerator: dilute 1 aspirin in a liter of water and spray the solution on the plants every 3 weeks. Don’t overdo it, as the plant could suffer.

To germinate the seeds: Soak the seeds in the solution of water and aspirin before planting.

In the soil : In order not to have to dilute the aspirin, you can put the tablets directly into the soil, about 15 cm from the plant, and then water regularly.
