What to do if dieffenbachia leaves turn yellow - find out the reason

Tell me what to do if dieffenbachia leaves turn yellow? Everything was fine, but yesterday, after returning from a two-week vacation, I saw a sad picture. The whole family was at the sea, and asked a neighbor to look after the flowers. Maybe I forgot to water, or it's very hot, but almost all the lower leaves turned yellow. How to save a plant?

One of the most common problems with growing indoor plants is yellowing of the foliage. Dieffenbachia is no exception, and yellowness is especially noticeable on its chic large foliage. Before deciding what to do if dieffenbachia leaves turn yellow, it is important to establish the cause of this phenomenon. This will help you to respond correctly and take adequate measures to save the flower.

So, the possible reasons for the change in the color of the sheet plate can be conditionally divided into four groups:

• changes in plant conditions (lighting and temperature);
• errors in care (watering, feeding, soil);
• diseases and pests.

What to do if dieffenbachia leaves turn yellow after changing conditions of detention

The yellow color begins to show through the foliage most often either in winter or summer. In the first case, this means that the bush lacks lighting. The deciduous cover first turns pale, loses the contrast of colors, and then a yellow tint appears on it. If the pot is on the north window or in the back of the room in winter, this will happen. And the reason will be the lack of lighting. It is enough just to rearrange the bush, and soon the green color will be restored.

In summer, direct sunlight becomes the main danger. They cause burns - large yellow spots that gradually dry out and turn brown. It is already unrealistic to restore such a sheet, it must be cut. But in order to save the rest, you should rearrange the flowerpot or shade it.

Dieffenbachia needs diffused lighting, while its daylight hours must have at least 10 hours. In winter, she will be better on the south window, but in the summer - on the east.

As for the temperature of the content, then it should be moderate, without sudden changes. If the room gets colder to 10 ° C, dieffenbachia will inevitably change the color of the lower leaves to yellow and discard them. It is important to avoid such values.

What care mistakes can not be made when growing dieffenbachia

Leaves also turn yellow with an excess of moisture in the soil. This may be due to too dense soil that does not have time to dry out, or excessive watering. In both cases, this is fraught with root decay and entails a mandatory plant transplant. The soil needs replacing, and it is advisable to treat the roots with a fungicide, even if they are healthy. This will serve as prevention. You need to water the bush regularly, but only after the top layer of the soil has dried.

It is also important to transplant flowers, because dieffenbachia has a powerful and rapidly growing root system. In a cramped pot, growth slows down, few nutrients enter the leaves, they turn yellow and fall off.

On the other hand, with a lack of moisture, the foliage also turns yellow, especially during the heating season. In winter, the batteries dry the air, and if it is also rarely watered, the bush will generally lose its foliage. It is necessary to periodically spray dieffenbachia. You can place the pot on a pallet with damp pebbles.

Do not forget about the nutrition of the flower, but do not get carried away with feeding.Both lack and excess of nutrients immediately affect the state of the leaves.

Diseases and pests of dieffenbachia

Various kinds of yellow spots appear on the foliage of the plant when it is sick. From excess moisture, root rot can develop, and from a lack of iron, chlorosis. The flower also suffers from various fungi and infections (anthracnose, necrosis, septoria, powdery mildew and others). It is important to immediately start treatment using special fungicides (Fitosporin, Fundazol, Vitaros), and be sure to change the soil in the pot.

Of the pests, the spider mites, aphids, thrips, and mealybugs are most fond of dieffenbachia. If insects are found, the flower must be treated with insecticides (Aktara, Actellic, Fitoverm).
