We determine and eliminate the causes of yellowing and drying of dieffenbachia leaves


Dieffenbachia is a popular houseplant that is characterized by rapid growth and bright green leaves. However, often gardeners are faced with the fact that the leaves of the plant begin to dry, turn yellow and deform. How to take care of the plant in order to prevent such phenomena?

Optimal conditions for the development of dieffenbachia at home

Dieffenbachia, although it is a favorite resident of the windowsills of many homes and offices, still requires a lot of care. Dieffenbachia is very moody therefore, those who grow it often face various difficulties. Choosing a place for a pot with a room flower is necessary based on the color of the leaves. If they are monophonic, then the plant must be placed in the back of the room, away from light. Dieffenbachia perfectly tolerates the shadow. But in this case, she will need additional lighting, especially in winter. In any case, it is necessary to avoid windows on the south side, since from direct sunlight, the plant may die.

The proper development of a tree depends on temperature. So for the warm season, the permissible norm in the room should be + 21 + 25. In winter and autumn, the air temperature should be from +15 to +20. In places where the flower pot is located, there should be no drafts, wind and sudden changes in temperature. To irrigate Dieffenbachia, you need to use pre-prepared water, which insisted for at least a day. In the cold season, you need to water the soil after its top layer has dried out a little. In summer and spring, watering should take place regularly and be plentiful. Drying of the soil is not allowed.

Dieffenbachia responds very well to water procedures, for this it needs to be periodically sprayed from the spray gun. This should be done so that excess moisture does not fall on the soil, it can be covered with polyethylene. If the plant is already large, the leaves can be wiped with a damp cloth. For the proper development of dieffenbachia, nutrition is necessary. To do this, you need to select fertilizers that do not contain lime. The procedure is carried out on average three times a month.

Features of growing dieffenbachia

Why dieffenbachia leaves turn yellow and dry

Since the exotic guest is rather capricious, her leaves often turn yellow and dry. This can lead to a violation in the process of care, as well as diseases that are quite common precisely for this type of plant. Why do plant leaves turn yellow?

Breach of Care Rules

Several factors can lead to violation of the rules for plant care. In the first place improper watering - it can be either excessively plentiful or insufficient. The air in the room where Dieffenbachia is located can be very dry. This also applies to office premises, where in most cases the lighting is artificial, and the flowerpot itself is on the windowsill, where sunlight hardly penetrates. No matter how strange it sounds, but in violation of the care of the plant, domestic animals may also be involved. They can bite or scratch the leaves of the flower, but damage may not be visible at first glance. Thus, an infection can be introduced that interferes with the normal development of the plant.

Dieffenbachia diseases and methods of their treatment

Dieffenbachia, like any living creature, can get sick and get infected. Fungal, bacterial and viral diseases can interfere with the normal development of plants. Leaf spotting, which first forms on the edges of the foliage, and then spreads to the entire plate, can be caused due to improper room temperature or high humidity. Also Stains can be caused by excessive watering and accumulation of fluid in the soil. To avoid such phenomena, it is necessary not only to revise the systematic irrigation, but also the water itself, which is used for these purposes.

Anthractosis - with a fungal disease, the stems and leaves are affected by small orange spots, which eventually merge into one large damage, leading to complete drying of the leaf. It occurs for the same reasons as regular spotting. Treatment of affected areas of the plant is carried out by spraying dieffenbachia with fungicides.

Fusarios - An infectious flower disease in which the roots and the basal part of Dieffenbachia are affected. Long orange spots appear on the affected areas, which lead to drying and death of the plant. The appearance of such an infection results in over-dried soil and a lack of fertilizer. To cure a tree, you need to remove the roots from the pot, rinse under water and get rid of the infected soil. Then spray the roots several times with preparations containing fungicides and transplant the plant into new soil.

How to deal with dieffenbachia pests

Root rot can lead to yellowing and drying of leaves. For this, as in the previous case, it is necessary to unearth the roots and clean them from infection. If the roots are black and have an unpleasant smell - this is a sure sign of the disease. It can be caused by excessive watering. To treat dieffenbachia, you need to clean the infected roots, transplant it to a new place, treat the soil with a fungicide and reconsider watering.

The leaves of the plant can undergo bacteriosis, during which watery spots with clear boundaries at the edges appear on the affected areas. The development of this disease can be triggered by infection during transplantation or cuttings. To get rid of the infection, you need to spray the plant with preparations containing copper.

Dieffenbachia pests affecting leaf condition

Despite the fact that Dieffenbachia is partly a toxic plant, it is also susceptible to attack by pests that harm it and affect the deciduous system. The most common parasites include:

  • spider mite
  • aphid
  • mealybug
  • scale shield

The control methods for each type of parasite are the same - it is necessary to carefully treat the trunk and leaves of the indoor flower with soapy water, and later wash off the surface of the flower with ordinary warm water. After this, you need to treat dieffenbachia with a specially prepared insecticide solution. If there are two or more plants in the house, it is necessary to process the rest of the house window dwellers, as parasites tend to move from one plant to another.

Natural causes

Natural causes can lead to yellowing of the leaves in dieffenbachia. In general, this is a natural process that concerns already old lower leaves. However, when the first spots and dry patches appear on the leaves, there is no need to rush to get rid of them and cut them to the root. You need to wait until the leaves are completely dry and begin to fall off. Florists assure that pruning leaves does the plant great harm.

Why do drops form on dieffenbachia leaves

It sometimes happens that drops form on the leaves of Dieffenbachia, flower growers call it “Dieffenbachia crying”. In most cases, this is a natural process in which moisture is released through special mouths - hydatodes. If the phenomenon occurs quite often, you need to reduce the amount of watering, but do carefully to prevent overdrying.

What to do if Dieffenbachia has small leaves

It happens that the leaves of a flower develop disproportionately to the trunk, in a word - they are very small or can curl around the edges. Sudden changes in temperature in the room where the plant is located can contribute to such a violation. It’s important to ensure that the flower has the correct moisture level, especially in winter when batteries start to work in the house. It is also recommended to spray the leaves of Dieffenbachia with special fertilizers.

Dieffenbachia leaf propagation technology

The beauty of Dieffenbachia is that it is quite easy to propagate. For this, an adult plant whose age is more than two years is better. It’s best to cut the leaf from the very top and as close to the trunk as possibleleaving a few kidneys on it. To avoid excessive secretion of juice, it is necessary to reduce watering a few days before pruning. It is better to cut the handle with a sharp blade with teeth, so as not to injure the internal fibers. The trimmed top can be put in water or immediately planted on the finished soil.

Pests and control of indoor plants

Dieffenbachia, although a rather demanding and capricious plant, still does not cease to be one of the most beloved flower plants. With proper care for 1 year, a rather tall tree with large green leaves grows, which will become the main decoration of an apartment or office.
