Why cyclamen leaves turn yellow when it blooms

Cyclamens are a genus of flowering herbaceous plants of the Primroses family. The second name is Alpine violet. The genus includes 20 species with varied flower colors (from white to purple) and varying leaf patterns. At home, the most common Cyclamen is 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 cyclamen leaves turn yellow at home

In nature, cyclamens grow in the warm Mediterranean climate, Spain, northeast Africa and the steppe regions of the Black Sea region. Cyclamen blooms with the arrival of spring and the wet season, then the flowering intensity gradually decreases. Tubers store nutrients to survive dry, hot summers, leaves wilt and a small patch of ground stem remains visible on the soil surface.

Cyclamen with yellow leaves

In late summer and early autumn, with the arrival of coolness and moisture, cyclamen vegetation resumes. In October, the bushes have a fully developed leaf cover and are preparing to discard flowering shoots. If at this time the leaves of the cyclamen turn yellow, you need to understand what to do, and whether this state threatens the life and health of the flower.

How to tell if yellowing is a disease or seasonal cause

If the summer dry period has passed, and the season of cool weather is ahead, the flower has developed well, and then yellowing has begun, then it is recommended to carefully examine the leaves with a magnifying glass.

It is recommended to pay attention to the following points:

• Browning, blackening and dying off of parts of the leaf are signs of diseases caused by fungi. The soil can give off a putrid smell. In the future, mold develops, and the plant can hardly be saved.
• For small spots on the leaves, you need to look for aphids or ticks on their back side, and on the shoots - scale insects.
• 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 wilt, and at the same time look "soaked" - the reason lies in the errors of care.

A careful approach will help you figure out why the leaves of the cyclamen turned yellow.

Fusarium disease

Improper care as the cause of yellow leaves

In winter, in a house or city apartment, it is difficult to maintain the air temperature at + 14 ... +17 degrees, usually it is higher. Air humidity should be at 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 must be removed to the north-west or north-east side, it can be taken out to a cool loggia or a glazed veranda in the house. Give watering 2 times a week in a tray, spray the plant with water no colder + 18 ... +20 degrees from a spray bottle.

Why do the leaves of cyclamen turn yellow during flowering, what to do

During the flowering period, the flower needs a full range of nutrients. We must not forget about regular watering and increasing the humidity in the room. If mold or moss appears on the soil, loosening should be carried out.

In late summer or early autumn, it is advisable to revise the plants, if necessary, update containers and soil, and carry out top dressing. The soil should have a pH level just below neutral - from 5.5 to 6.0. The diameter of the container should exceed the tuber by 1.0-1.5 cm. A full-fledged complex with macro- and microelements Reasil is suitable for feeding. In the midst of flowering, the plant can be fed again with the same complex with an interval of 15-20 days.

Improper care

Diseases and pests causing yellowing and wilting of leaves

Fusarium and anthracnose diseases begin with yellowing of the leaves. The yellowing is joined by the browning and dying off of parts of the leaf. An urgent need to treat the plant. To exclude contamination of other specimens, 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 soil in containers with the solution.

It is more difficult to save the plant if it is sick with 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 treatment. You should carefully dig out the bush and examine the tuber and root system. If there is blackening and gray coating, these are signs of root rot infection. The damaged flower and soil should be discarded and the containers disinfected.

Cyclamen insect pests:

• aphid;
• ticks;
• thrips;
• scabbards.

Affected plants are severely depressed, diseases join, and flowers are difficult to preserve. On the leaves, traces of an invasion of thrips or aphids (from the back side) are visible. The plant can become infected through the soil or containers from the store.

Thrips damage

At the first signs of the presence of insect 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 re-sprayed with Actellik. For maintenance spraying, the biological pesticide Fitoverm is used.

If the leaves of cyclamen turn yellow and wither during home care, careful attention to it will help restore the health of the plant and prolong flowering.
