What to do if the leaves of Catharanthus roseus turn yellow and fall off
The editor will tell you about what to do if the leaves of Catharanthus roseus turn yellow and fall off, and provide detailed information on the care methods for falling leaves in spring flowers and related plant knowledge. Next, the editor will introduce.
Lack of light: If Catharanthus roseus is kept in a shaded environment for a long time, it cannot perform photosynthesis properly, which can easily cause yellowing and leaf drop. It should be exposed to more sunlight.
Unsuitable soil: If the soil is too heavy, it will hinder the root respiration, leading to yellowing and leaf drop. The soil should be changed as soon as possible.
Low temperature: It has poor cold resistance. If it cannot be well insulated and warmed in winter, it will freeze easily, leading to yellowing and leaf drop. Insulating measures should be taken.
Too much watering: If excessive watering causes waterlogging in the potting soil, it can lead to root rot and yellowing leaves. The water should be drained as soon as possible.
I. Lack of light
Catharanthus roseus is a plant that loves light and has poor shade tolerance. If it does not receive enough light for a long time during cultivation, it cannot perform photosynthesis properly, which can easily cause yellowing and leaf drop. If this is the cause, Catharanthus roseus should be moved to a well-lit area as soon as possible to expose it to more sunlight. It is best to receive more than 5 hours of sunlight a day, which can promote the gradual recovery of Catharanthus roseus and return to normal growth.
II. Unsuitable soil
Catharanthus roseus has high requirements for soil and prefers loose, breathable, well-drained, and fertile soil. Only in such an environment can it grow vigorously without growth problems. If the soil used is too sticky, the roots cannot breathe properly over a long period, leading to poor growth, root rot, and eventually yellowing and leaf drop. If this is the case, it is necessary to change the potting soil of Catharanthus roseus as soon as possible, prune the rotten roots, and manage them again.
III. Low temperature
Catharanthus roseus prefers a warm environment and has limited cold resistance, fearing low temperatures. If it is exposed to a cold environment for a long time, and cannot control the temperature well in winter, it is easy to freeze, leading to yellowing and leaf drop. If this is the case, the temperature should be increased as soon as possible, or moved to a warm environment, with a minimum temperature control above 10°C. In such an environment, Catharanthus roseus will soon return to normal growth and can safely overwinter.
IV. Too much watering
Catharanthus roseus fears waterlogging environment. If the watering cannot control the amount of water well, and the potting soil has long-term waterlogging, it can easily lead to root rot and easily cause yellowing and leaf drop. If this is the case, the accumulated water should be drained as soon as possible, and ventilation should be strengthened to evaporate the water as soon as possible. Watering Catharanthus roseus can follow the method of not watering when dry and watering thoroughly when watering, strictly prohibiting waterlogging.
