Why do flowers and plants need to be turned in their pots during care?
During the care of flowers and plants, we often turn the flower pots. We know this is mainly to allow the flowers to receive sunlight evenly. But have you ever thought about the reasoning behind it? The editor will give you a detailed introduction to the reasons for turning pots during flower care. Friends who are interested can learn about it together.

Turning the pot means frequently changing the direction of the flower pot during the growth period of the flowers. Because some flowers and plants have phototropism, if the light is not adjusted by turning the pot frequently, undesirable shapes such as an uneven crown will appear, affecting ornamental value. Why do flowers have phototropism? This is the result of the action of auxin in their bodies.
Most auxin is concentrated in vigorously growing parts, such as the meristematic tissues at the stem tip, buds, and root tips, cambium cells, and young leaves. Therefore, young leaves and young branches show strong phototropism, while old leaves and old branches show weak or no phototropism. Experiments show that light can change the distribution of auxin. The phototropism of flowers is related to the uneven distribution of auxin caused by unilateral light.
For example, someone conducted an experiment with geraniums. Measurements showed that the auxin on the lighted side of the stem was 35%, and on the shaded side it was 65%. The cells on the side with more auxin grow faster, and the cells on the side with less grow slower. As a result, the stem bends toward the side with slower growth, that is, toward the sunny side, causing the plant to show phototropism. Because of this, if the pot is not turned for a long time and the plant is allowed to grow naturally, the plant will grow lopsided. Some flowers such as clivia grown by flower enthusiasts sometimes have leaves that grow crooked and twisted, and the reason is that the pot was not turned frequently starting from the seedling stage.
In order to keep flowers and plants in a well-proportioned shape, attention should be paid to regularly changing the direction in which potted flowers are placed. Especially during the vigorous growth period of the flowers, the direction of the flower pot should be turned about once every 7 days. Each time you turn the pot, it is best to rotate the flower pot 180° in place. In this way, the leaves can be distributed evenly, the flower heads will be upright, and the plant will stand straight without leaning.
