Latest Causes and Solutions for Yellowing and Dropping Leaves on Cuban Oregano

Cuban oregano (Plectranthus amboinicus) is a shrub-like herbaceous plant that gives off a unique fragrance all over, and this fragrance becomes even stronger after you touch it, so quite a few people grow it. But many friends find that the leaves of their Cuban oregano turn yellow and drop during cultivation. What is going on here? Let's take a look.

1. Metabolism

Sometimes the leaves of Cuban oregano appear yellow, and this may be caused by the plant's own natural growth, because after being grown for a long time, the leaves of Cuban oregano will gradually become woody, and the surrounding leaves will turn yellow and gradually wither. If this is the case, then there is no need to worry, because this is a normal physiological phenomenon, and after its leaves wither it will still grow new branches and leaves.

2. Overwatering

Cuban oregano is not tolerant of waterlogging, and during care, watering may cause root rot, and root rot will lead to yellowing and dropping of the plant's leaves. So when caring for it, pay attention to watering it by the principle of watering when the soil is dry and stopping when it is wet. On rainy days, watering should be appropriately reduced or stopped, and especially in low-temperature seasons, watering must be strictly controlled to avoid water accumulating at the bottom of the pot and causing root rot. Too much watering in winter can also cause cold damage to Cuban oregano.

3. Insufficient Light

Cuban oregano is a sun-loving plant. It likes to grow in an environment with sufficient light, and when grown in an environment with sufficient light, its leaves will be thicker and more verdant. If it is kept in a shaded place for a long time, then its leaves will become thinner and yellow and poor. In addition, when placing it in the sun, you should also pay attention, as the intense light at noon may cause its leaves to turn yellow, so at this time you should provide appropriate shade, and it is best to place it in a place with relatively good ventilation for care, not on a closed balcony,

4. Excessive Touching

Cuban oregano gives off fragrance after being touched, so many people like to frequently touch its leaves, but excessive touching can also have a relatively large impact on its growth, causing physiological disorder in the plant, thereby causing yellowing and dropping of the leaves. At this time, it is necessary to reduce touching of the plant, strengthen daily care, control light and moisture well, and at the same time strengthen ventilation to let it recover.
