What is the best remedy for dry heating air in winter? A natural humidifier called hydrangea. The flowers and voluminous foliage evaporate water and thus improve the indoor climate in a completely natural way, as confirmed by scientists
While the large, round flowers of hydrangeas are a treat for the eye, the dense, green foliage and small petals increase humidity, creating a healthier indoor environment. The abundant irrigation water absorbed through the roots is transported by the hydrangea towards the foliage and flowers. There it evaporates and is released into the surrounding room air. Especially in the cold season, when heating air can lead to dry skin and eyes as well as headaches, the indoor plant provides relief in a natural way.
Scientists at the Fytagoras Plant Sciene research institute in Leiden/Netherlands have found that no other indoor plant studied to date improves the indoor climate as significantly as the hydrangea. It was found that nine indoor hydrangeas raise a low humidity of 30 percent to a much healthier level of 40 percent within four hours. Especially during the cold winter months of January, February and March, plan for at least two indoor hydrangeas per room to improve the indoor climate. The rule here is: the more, the better.
In order for the hydrangea to evaporate as much as possible, it should be watered regularly so that the pot ball never dries out completely, depending on the size, location, sunlight and temperature of the environment, so about two to three times a week, but waterlogging should be avoided. A drainage layer of clay granules is helpful. Checking the moisture level of the potting soil with your finger quickly tells you whether watering is necessary.
Since the flowering houseplant prefers acidic soils, the irrigation water should be as low in lime as possible, e.g. rain water. To ensure that the joy of the opulent blossoms lasts as long as possible, the plant is best placed in a place with plenty of daylight but without direct sunlight during the midday hours. As soon as the temperatures outside are getting higher, the indoor hydrangea can be repotted and spend the summer outdoors.
