Here’s how to revive the color of your geraniums with a very simple method.
How to revive the color of your geraniums. If you have geraniums in your garden, here are some “tricks” and small precautions to protect their health and revive their colors.

One of the keys to plant health in general and geraniums in particular is soil fertilization. With this in mind, it is always advisable to choose fertilizers rich in phosphorus, nitrogen and potassium. If you don’t want to use industrial products, classic coffee grounds are also suitable.
Geraniums are best suited to acidic soils, perhaps rich in peat moss and clay. For good drainage, gravel should always be placed at the bottom of the pot and only after the soil.
Water
In summer, it is important to water geranium plants constantly – they need the soil around them to be moist at all times. Even in winter, the soil should never dry out.
The ideal temperature
Geraniums should be exposed to the sun at a temperature of between 15 and 25 degrees. In the colder months, it is advisable to protect them with nylon covers.

The right vase
If the plant is medium-sized, a pot with a diameter of about 20 centimeters should be enough. If it is large, the diameter should at least double.
the dry leaves
Dry leaves and dead flowers should be removed periodically to make room for new inflorescences.
