If your roses, geraniums, or hydrangeas are not blossoming, a single spoonful of this ingredient can bring them to life, vibrant and at their peak beauty. Discover the natural remedy that works wonders for these diverse plants.

It might seem peculiar that a single solution can cater to such different plants, but nature has its own ways. Let’s break it down and understand the unique characteristics of each.


Adored for centuries, roses symbolize love, admiration, passion, or jealousy, depending on their color and context. While they can adapt to temperatures ranging from 12 to 25 degrees Celsius and might even bloom in winter with a mild climate, they crave sunlight. Placing them strategically on balconies, terraces, or in gardens is essential.


Known for their resilience, hydrangeas should avoid direct sunlight as they easily transpire and dry out prematurely. The vibrant or subtle hues of their blooms depend on soil acidity, rainfall, and air conditions. Consistent watering brings out the best in them, showcasing their beauty, especially in September.


Easy to cultivate, geraniums flourish when temperatures range between 15 and 25 degrees Celsius. They thrive in direct sunlight, painting balconies and terraces with magnificent blooms in the summer. Beyond their aesthetic appeal, geraniums act as natural mosquito repellents due to their intense fragrance, often found in insect-repellent sprays.

All three plants share a common need for a mineral not always present in the cultivation soil: magnesium. If the soil lacks this essential mineral, flowering may suffer, particularly in summer due to increased dispersion during chlorophyll photosynthesis.

Fortunately, the remedy is simple. You can purchase magnesium powder and add a tablespoon to 10 liters of water, then use two liters at the base of your roses, geraniums, and hydrangeas.

Alternatively, you can soak a banana peel in 500 ml of water overnight and dilute it in your watering can. Bananas are a rich source of magnesium and potassium, serving as a natural fertilizer while reducing waste.

Isn’t it ingenious?

Give it a try, and you won’t regret it!
