Cyclamens are a genus of flowering herbaceous plants of the Primrose family. The second name is Alpine violet. The genus includes 20 species with varied colors of flowers (from white to purple) and a varying pattern of leaves. At home, the most common Cyclamen Persian. It is considered a capricious plant, and it can be difficult to understand why its leaves turn yellow, the flower dies or goes into the physiological stage of dormancy.
Why do cyclamen leaves turn yellow at home
In nature, cyclamen grow in the warm Mediterranean climate, Spain, northeast Africa and the steppe regions of the Black Sea. Cyclamen blooms with the advent of spring and the wet season, then the flowering intensity gradually decreases. Tubers store nutrients to survive dry and hot summers, leaves fade, and a small area of the ground stem remains visible on the surface of the soil.
Cyclamen with yellow leaves
In late summer and early autumn, with the arrival of coolness and moisture, the cyclamen vegetation resumes. In October, the bushes have a fully developed leaf cover and are preparing to throw flower-bearing shoots. If the leaves turn yellow at the time of cyclamen, you need to understand what to do and whether this state of life threatens the life and health of the flower.
How to determine if yellowing is a disease or seasonal cause
If the summer dry season is over and the season of cool weather is ahead, the flower has developed well, and then yellowing has begun, it is recommended to carefully examine the leaves with a magnifying glass.
Important! With seasonal yellowing, the leaf plate gradually changes its color to a bright yellow color, gradually all leaves without browning and spots with a white fluff are involved.
It is recommended to pay attention to the following points:
- Drilling, blackening, and dying off of parts of the leaf are signs of diseases caused by fungi. The soil may emit a putrid odor. In the future, mold develops, and the plant is difficult to save.
- With small spots on the leaves, you need to look for aphids or ticks on their back side, and on the shoots - scabies.
- If the color of the leaf changes to pale yellow or whitish with drying edges without browning and blackening, the flower lacks nutrients.
- If the leaves turn yellow and turn pale at the same time as the petioles wither, and at the same time look “soaked” - the reason lies in the errors of care.
A careful approach will help to understand why cyclamen leaves have turned yellow.
Improper care as a cause of yellow leaves
In winter, it is difficult to maintain an air temperature of + 14 ... +17 degrees in a house or city apartment, usually it is higher. Humidity should be at the level of 55-60%, but in houses it is much less. This leads to the fact that the leaves of the flower begin to turn yellow (from the lower tier). To solve the problem, the flower needs to be removed to the northwest or northeast side, it can be taken out to a cool loggia or a glazed veranda in the house. Watering give 2 times a week in the pan, spray the plant with water no colder than +18 ... +20 degrees from the spray gun.
Why cyclamen leaves turn yellow during flowering, what to do
During flowering, a flower needs a full range of nutrients. We must not forget about regular watering and increasing humidity in the room. If mold or moss has appeared on the soil, loosening should be carried out.
Additional Information! In large pots, cyclamens feel uncomfortable, they stop flowering, and leaves may turn yellow.
At the end of summer or the beginning of autumn, it is advisable to carry out an audit of plants, if necessary, update containers and soil, and top-dress. Soil should have a pH level slightly below neutral - from 5.5 to 6.0. The diameter of the container should exceed the tuber by 1.0-1.5 cm. For feeding, a full-fledged complex with macro- and microelements Reasil is suitable. At the height of flowering, the plant can be fed again with the same complex with an interval of 15-20 days.
Diseases and pests that cause yellowing and wilting of leaves
Fusarium and anthracnose diseases begin with yellowing of leaves. The yellowing is accompanied by the browning and dying of parts of the leaf. An urgent need to treat the plant. To exclude infection of other instances, the container is isolated and sprayed with Topaz. After 4-5 days, it is advisable to treat the flower with Alirin B and pour the solution with soil in containers.
It is more difficult to save a plant if it gets root rot. The causative agents of this pathology are a number of microscopic fungi. Infection occurs through soil or old containers that have not undergone decontamination. Carefully dig out the bush and examine the tuber and root system. If there is blackening and a gray coating - these are signs of infection with root rot. Damaged flower and soil should be discarded and containers disinfected.
Cyclamen insect pests:
- scale insects.
Affected plants are very depressed, diseases join in, and flowers are difficult to preserve. Traces of thrips or aphids (on the back) are visible on the leaves. A plant can become infected through soil or containers from a store.
At the first signs of pests, treatment with Fufanon is required. If aggressive insects, such as scale insects or aphids, could not be neutralized after a single treatment, after 7-10 days, they are sprayed again with Actellik. For maintenance spraying biological Fitoverm pesticide is used.
If cyclamen leaves turn yellow and fade when leaving at home, careful attention to it will help restore plant health and prolong flowering.
