Why do monstera leaves turn yellow - diseases and pests

Indoor plants can beautify any interior. However, it is important to provide them with proper care.

The main reasons for yellowing foliage

Monstera is an evergreen, unpretentious houseplant. She has large leaves, decorated with peculiar cuts. It is thanks to her qualities that she has earned the special love of novice and experienced florists. However, it happens that the lush and dense green of the flower turns yellow and begins to fade. So the monstera shows its owner that the rules of leaving have been violated and they need to be urgently corrected. Below is considered in more detail why monstera leaves turn yellow.

Incorrect lighting

This plant may suffer from insufficient light or, conversely, from direct sunlight. The yellowed leaves will "tell" about this florist. What to do if monstera leaves turn yellow?

Healthy monstera

Pale green leaves with yellow spots indicate direct sunlight. Monstera is native to the tropics, so it can be unusually abundant in light. When the first signs appear, it is recommended to move the flower away from the window and shade it. It is preferable to choose the north and west sides of the house.

In winter and autumn, monstera prefers to be closer to the south or east side. Otherwise, the leaves will begin to discolor.

Water imbalance

The brown color of the tops of the leaves and massive yellowing indicate excess moisture. As soon as such signs are noticed, the amount of watering should be reduced and the spraying should be reduced. Despite the fact that the leaves of this flower are able to independently remove moisture through the mouths on the leaves, the root system needs aeration. In order for the roots to receive the oxygen they need, you need to allow the earth to dry completely, and only then water it abundantly.

The lack of moisture also negatively affects the plant. In this case, the lower leaves turn yellow, and the new ones grow very small. In this case, the upper leaves of an unnatural dark green color. In this case, it is necessary to increase the frequency of watering and spraying.

Spraying monstera

Temperature regime

If the leaves turn brown and feel like paper, they will soon begin to fall off en masse. This suggests that the room temperature is uncomfortable for this semi-epiphyte. Most often, this phenomenon is observed in the winter period of time. It is necessary to move the flower away from batteries and other heaters. They are the main reason why the leaf tips dry out in monstera. In winter, it is also recommended to put a humidifier or a decorative fountain near the flower. They will slightly lower the temperature of the air and humidify it.

Incorrectly selected soil

A newly purchased flower from a flower shop is recommended for replanting. The adaptation period is 1-2 weeks. Then you can start the transplant. The fact is that in stores, fertilizers and growth activators are often added to the soil. Their abundance can negatively affect the root system and lead to burns. This will be evidenced by the leaves turning yellow from above. At the same time, their edges dry.

Specialized primer for monstera

Monstera soil should be slightly acidic or neutral.When purchasing soil in a store, you need to choose a universal soil for indoor plants. You can also prepare the soil for monstera yourself. To do this, you need to collect the following ingredients in equal proportions:

• leafy land;
• peat;
• humus;
• sand.

Lack of nutrients

Pay attention to the composition of the soil when buying. It should indicate nitrogen, phosphorus, iron, calcium and potassium. These ingredients will provide dense, vibrant greens and large leaf blades.

It is necessary to think over the fertilizing schedule. In summer and spring, it is recommended to apply the mineral complex once every 2 weeks. If the bush is large, then some growers recommend adding humus to the top layer of the soil. In winter, feeding is reduced to 1 time in 1-1.5 months

Monstera pests

Monstera, like many other house flowers, is susceptible to certain diseases and pests. Having brought home a new flower, you should adhere to a 2-week quarantine. This will help avoid massive damage to other colors. If, nevertheless, the pests showed themselves, then it is necessary to immediately begin to fight them. To choose a treatment, it is important to determine which pest has settled, and choose a convenient method.

Spider mite

This pest can appear due to dry indoor air. It is characterized by the appearance of a small web in internodes. After a while, the leaves begin to turn yellow, wither and fall off. To get rid of spider mites, it is necessary to regularly process the leaves with a damp sponge dipped in soapy water. Alternatively, you can consider washing the bush under a warm shower.

If the listed methods turned out to be ineffective, then the plant is treated with a biological product - Aktellik.

Aphid

What to do if monstera leaves turn black and why does this happen? When aphids appear, a characteristic curvature of the tops of the leaves occurs, and the leaves become sticky. In the worst case, black dots may appear that interfere with the process of photosynthesis. The negative consequences develop very quickly. However, aphids are fairly easy to deal with. To effectively combat the parasite, you need to prepare a decoction of onion and garlic husks and regularly spray them.

Shield

The appearance of this parasite is accompanied by the formation of brown plaques on the leaves. They suck the valuable cell sap from the flower. The process is accompanied by yellowing and drying of the leaves, which subsequently fall off. The fight against the scabbard, as in the case of the spider mite, is carried out using a soap solution. The regularity of processing is 1 time in 2-3 days.

Alternatively, you can treat with a specialized insecticide.

Mealybug

The affected area is shoots and young leaves of monstera. The lesion is characterized by curvature of leaves and a carved pattern, accompanied by falling off. The treatment is carried out with soapy water.

Leaves are the main indicator of disease and pest damage

Plant healing

In some cases, yellowing of foliage is caused by infections. Moreover, the leaves not only turn yellow. Sometimes monstera leaves turn black, what should I do in this case?

Fusarium is a dangerous fungal disease that is transmitted through soil that has not passed the disinfection procedure. The root system rots and is unable to provide the flower with nutrients. The leaves turn yellow. Nothing can be done to heal. Unfortunately, the tropical friend will have to be thrown out so that he does not infect the rest of the plants.

Late blight is another fungal disease that affects not only the roots, but also the aerial part.The disease is characterized by the formation of white bloom and brown spots on the back of the leaves. If signs are found, the treatment is carried out with a solution of Fitosporin. Treatment is effective only at the onset of the disease.

Light yellow spots with brown edging indicate the development of anthracnose. Treatment consists of cutting off the affected areas and treating with copper sulfate. If a significant part is affected, then the treatment is likely to be ineffective.
