Monstera is an amazing vine that was brought to us from the tropics. Modern name plants translated from Latin means "monster". Monstera was discovered in the eighteenth century, and immediately its name was shrouded in many scary legends... Many travelers of that time told stories about the killer plant, as they often saw human skeletons in the jungle, strung on the roots of this vine.
Today this plant is very popular with flower growers due to its beautiful foliage and unusual appearance. The flower leaves have a striking openwork shape. But the monstera is quite whimsical, and with poor care or disease, he immediately makes it known by changing the state of the leaves. Therefore, many gardeners often have a question: "Why does the monstera turn yellow?"
The main problem that growers face when growing monstera is yellowed leaves.
Causes of yellowing monstera leaves
This state of the plant can be due to a number of reasons, namely:
- If all the leaves of the plant turn yellow, and then gradually turn pale, this can only mean that there is a lot of light for the plant. shaded places, therefore, in case of direct sunlight hitting it, the flower must be covered with a curtain or moved away from the window.
- If, on the contrary, there is no sufficient lighting, then in this case the vine can completely discard the foliage. If the monstera is in a too dark place, then it must be rearranged closer to the windows. Otherwise, the plant may leave only a few leaves on the crown, and discard the rest.
- If yellowness and brown spots appear on the lower leaves of the plant, and the young foliage remains a rich green color, then it is worth revising the amount of watering. Maybe it is not enough for the normal development of the plant and it is worth increasing the amount of moisture.
- If, together with the appearance of yellowing, the leaves of the flower wither and dry, then this may indicate an excess of moisture and damage to the root system of the plant. In this case, it is worth reducing watering, and cutting off the withered leaves. If the situation is critical, then you can try to transplant the plant into new soil, and during the transplanting process, you need to remove the rotten roots. For three to four days, the monster does not need to water.
- Another factor that provokes the appearance of yellowness may be a lack of nutrients. To remove this cause, you can feed it with ash or nitrogen fertilizers.
If the leaves turn yellow and dry out
In cases where the foliage does not just turn yellow, but gradually dries out, it can speak of too high air temperature and low humidity. Do not forget that liana is tropical plant... Most often, monstera owners are faced with a similar problem with the onset heating season... The same situation can be repeated in summer, when the plant is in direct sunlight. In order to save the flower, it must be moved to a cooler place.
Sometimes the leaves of the plant turn yellow only at the edges. This problem occurs if it is too close for it or the plant does not receive the required amount nutrients... In such cases, an urgent transplant into a more spacious container and top dressing with suitable fertilizers are necessary.
Another reason for the yellowness of the leaves can be pests: or. To resuscitate a flower, the foliage and trunk must be rinsed soapy water... Then rinse clean water, and further carry out regular treatment for prevention. If the plant is badly affected, then you will have to use special chemicals.
Yellowness and wilting of monstera leaves
This problem most often occurs in autumn-winter period if at a low temperature the owners continue to water the vine abundantly. In such situations, the life processes of the flower are inhibited, and the leaves gradually dry out. To restore the normal development of the plant, it is necessary to adjust the temperature in the room, and check if there are any problems with the level of humidity. The amount of watering should be reduced.
Leaf blackening problem
Black leaves on the monster can indicate a variety of problems:
- If such spots appear on healthy, rich green foliage, then it is necessary to reduce the amount of watering or, in extreme cases, to transplant a flower with significant lesions.
- If before blackening appear first yellow spots and the tips of the foliage dry out, this, on the contrary, indicates insufficient moisture in the soil.
Why do the leaves turn yellow
Monstera's leaves often turn yellow if the amount of light or moisture does not suit her. The plant is usually placed on or near a windowsill on the southwest or southeast side so that all the leaves get enough light. At the northern window natural light far less. If you do not organize additional lighting with an electric lamp, then the plant will lose its saturated green color, will slow down growth. But direct sunlight is also dangerous - it can burn.
Leaves turn yellow if the room is dry. On a hot day, the monster does not need to water more often: the roots consume less moisture, you need to spray clean warm water, wipe with a damp soft cloth. A humidifier can save the day, a pot with a plant can be put on a pallet with wet expanded clay or simply placed around a container with water. Some growers wrap aerial roots with wet rags at high temperatures.
If you water the monstera too often at low temperatures in winter, its leaves will turn yellow. Yellowing and loss of turgor will result from placing the pot in a draft. If the soil in the pot is too heavy or if it has got lost because it has not been changed for a long time, the result will be the same - yellowing, slow growth, discolored spots may appear on the leaves.
Why do the leaves turn black
Leaves can turn black from the cold when the air temperature drops below the permissible level. But this is usually how the consequences of a violation of the moisture regime manifest themselves. If you water the plant too often, do not drain. excess water from the pallet, the leaves will be covered with black spots. Most likely, it will be dry or wet rot. Excessive moisture, like excessively heavy soil, does not allow air to pass through, the roots remain without oxygen, and they can begin to rot. It is clear that root decay will immediately negatively affect the state of the aboveground part, it will manifest itself as black spots.
With insufficient watering, when the earth dries up completely, the leaves, starting from the lower ones, will first turn yellow and then turn black. If the situation is not corrected, then the whole plant will dry out.
If the tip of the leaf turns black, and spots appear on the plate, this may indicate a pest attack. Why is this happening? Dry air around flowers creates conditions for the reproduction of spider mites, thrips. Aphids or scale insects can move from other plants, which feed on plant sap, secrete substances that attract fungus.
Inattentive growers can only notice black spots that gradually increase - this is a sooty mushroom growing. The fight must be waged not only with him, but after carefully examining the entire plant, find aphids or scale insects. The fungus is removed with a cotton swab dipped in soapy water, and then the plant is treated with special preparations to get rid of the root cause.
Why do leaves dry
Why do monstera leaves dry, if there are no drafts, pests, and a comfortable air temperature is maintained? Most likely, this comes from a lack of moisture. The earthen lump should not dry out either in winter or in summer. The soil should always be kept slightly moist to avoid stagnant water in the pot. The frequency of watering depends on the season, temperature and humidity level in the room, and the age of the plant. Therefore, it is difficult to accurately indicate the watering schedule, but an attentive florist will install it himself, one has only to observe the monster, before watering, check the moisture content of the soil with a dry wooden stick or just your finger.
When the lower leaves dry, the appearance of new ones slows down, they grow small, not carved, the number of aerial roots increases, which indicates that the plant lacks nutrients for normal development. Wood ash, which is applied simultaneously with watering, or special fertilizers for monstera, can save the day. You can transplant a flower, completely change the soil, take a slightly larger pot. This must be done carefully, trying not to injure the roots.
What to do
To avoid such troubles, you need to create indoor flower comfortable conditions and provide him with attentive care. Monstera loves sunlight, but not direct sunlight. Daylight hours should last at least 10-12 hours. If the sun is not enough, you should get a phytolamp.
The air temperature in winter should not be lower than +16 ° C, and watering is carried out in 10-15 days. If difficulties become a consequence improper watering, then you need to urgently restore it. When the soil is overdried, it may be enough to just start watering correctly, and when overflowing, a transplant may be necessary. A transplant will save the plant if the potted soil is too heavy, rotten, or infertile. The rotten parts of the roots will have to be cut off, the cuts will be treated with charcoal.
Monstera is a beautiful houseplant, originally from South America... Inexperienced growers do not understand why the leaves of the monstera turn black. And in this way she signals about errors in care or maintenance conditions: the leaves can wither, turn yellow, dry out.

In this video, an expert will tell you how to save a monster and other indoor plants from diseases and pests.
Each houseplant requires attention to itself. If you decide to have a decorative monster, then you need to create for it favorable conditions... Only in this case beautiful plant will delight you with its fresh and healthy look.
Proper care of indoor plants allows you to avoid damage to monstera leaves from various diseases. If the conditions are not suitable, then there will be signals of problems in the form of discoloration of the leaves, blackening, dryness and even dropping.
Problems with growing monstera
In monstera, the leaves can turn yellow, then blacken and dry. If this happens to the lower leaves, it means a high temperature in the room. Such plant symptoms can occur in winter time air when the batteries are turned on, when there is no ventilation and the room is stuffy or even hot. If in summer a flower stands on a windowsill and direct sunlight falls on it, then it is likely that the same will happen.
If the monstera leaves turn black at the edges, this means that the pot in which the plant sits has become small for the root system. A similar situation can occur in winter when the soil is highly moistened. It is very important that the watering is moderate. Monstera leaves are affected by drafts. The problem is solved as simple as shelling pears - just move the flower to another place.
The reasons why they turn black beautiful leaves there are a lot of decorative monstera. To identify the problem, first of all, you need to observe the houseplant. It can be a lack of moisture that leads to yellowing, blackening and dryness. The soil should be moderately moistened, and the bush itself should be periodically sprayed.
If the leaves change their color dramatically and become black, then this indicates an excess of moisture. A similar phenomenon may mean that it is time to change the land to a new one and pick up a larger pot. When transplanting, it is imperative to prune old roots. Fertilizers should be added to the ground for this species indoor plants and wood ash.
Causes of blackening of leaves in monstera
Very often, amateur flower growers notice how their favorite flower begins to wither. The reasons that lead to a change in the shape of the leaves and their blackening are a lot of sun, lack of sunlight, a lot of water, cold temperatures, poor nutrition.
- If the lower leaves first turn yellow, then black dots appear on them, then this indicates insufficient watering.
- Little light affects the appearance of black spots. If you do not pay attention to this, then soon one barrel may remain.
- Many yellow leaves with black spots can indicate an excess of sunlight. In this case, the plant should be rearranged.
- Yellowness, black spots and signs of wilting indicate that wilting is taking place in the plant. It is very important to eliminate moisture.
- Lack of fertilizer results in black spots. Wood ash or special bait in the form of fertilizers restores nutrition well.
If you take care of the plant correctly, then diseases rarely affect the bush and leaves of the monstera. In case of violation of the conditions of detention, Monstera signals the onset of problems with its appearance: changes in color, abscission, dryness, change in shape, as well as underdeveloped leaf size. For clarity, we will consider specific changes appearance Monsters (leaves turn yellow or dry, the appearance of spots, etc. ...)
Often, flower growers complain that the leaves of the monstera turn yellow. Why is this happening? The main reasons are bay, cold, too much sun, lack of light and lack of food. Since the problem is common, let's take a closer look at it.
- If only the lower leaves have turned yellow, small brown spots have appeared on them, and fresh leaves are dark and small, then there is not enough moisture - watering should be increased.
- A case of global yellowing of the leaves followed by a pale color indicates the fact that the plant is receiving too much sunlight. Save the bush from direct sunlight by covering the window with a light curtain.
- Meanwhile, insufficient lighting also provokes their yellowness, however, under such circumstances, they still begin to fall off. If you do not increase the light supply in time, you can get a bare trunk with several apical leaves of a pale green color.
- The appearance of yellow leaves with signs of wilting and decay speaks of the bay of the plant. In this case yellow leaves should be removed and moisture should be reduced.
- The best measure for detecting rotten roots is an emergency Monstera transplant. In this case, rotten roots should be removed, and the remaining ones should be sprinkled with charcoal. Transplant the plant into a pot of smaller diameter and do not moisten the soil for three days.
- Do the leaves keep turning yellow? Then it's all about the lack of food. Fertilize the ground special means or wood ash(2 tablespoons for three liter jar water).
- Small and poorly cut leaves signal a lack of light. To solve this problem, it is enough to increase the flow of sunlight. Meanwhile, the appearance of a pale color of the leaves speaks of the opposite problem - it is required to reduce the sun's rays on the plant.
Problems in the process of growing Monstera
- Monstera leaves dry.
In the case of drying out and falling of the lower leaves, we can talk about an excessively high temperature in the room. Often, such cases are recorded during the heating season, if the plant is located next to the radiators; or in summer - when the bush is in direct sunlight. Moving the plant or lowering the temperature can fix the problem. Meanwhile, the regular loss of a few bottom sheets is the usual path of Monstera's development. It happens that only the edges of the leaves dry and turn brown, such cases are observed when the pot is too small for the Monstera or it needs increased nutrition.
- Sluggish leaves of monstera.
Typically the problem sluggish leaves appears in winter months, when low temperature air is accompanied by abundant soil moisture. To restore health to the leaves, you need to even out the temperature background and reduce watering. Along with lethargy, yellowness may be observed, which will also go away when the recommendations are followed.
- Leaves curl.
The facts of leaf curling indicate that the room is too hot, especially often such problems are observed in winter. Normal temperature regime Monstera is a corridor between 15 and 20 degrees plus Celsius.
- The appearance of spots on the leaves.
Brown spots on the leaves of Monstera may indicate that the bush is in a draft. To solve the problem, it is enough to move the plant. It should be noted that when placing the Monstera on the aisle, you can expose it not only to a draft, but also to the risk of deformation of the leaves, which, when touched, break easily. More dark spots on signal bush bay. In this case, the plant should be transplanted according to the above recommendations. In general, excess moisture is fraught with heavy restoration of the bush.
- Monstera leaves turn black.
There are a lot of reasons for the appearance of blackness on the leaves. To find the root of the problem, you need to observe the plant. If blackness is preceded by yellowing and dryness, then often it's all about a lack of moisture. Moisten the soil liberally and spray the bush. The case of the color of the green leaves immediately turning black - signals that the plant is excessively flooded with water. In this case, the leaves can begin to rot and become covered with black drying spots. If not only the leaves have become black, but also their rudiments inside the buds, then the land in which it grows is not suitable for Monstera. It should be transplanted, adhering to the composition of the soil indicated above.
Diseases and pests of Monstera
Spider mites usually appear in excessively dry air. On the stems, a cobweb appears in the internodes, the leaves wither and fall off. To bring the Monstera back to life, you need to wipe the plant with a damp sponge and soap or wash the bush under a warm shower. Then regularly spray the leaves with water. If defeat spider mite strong, then spraying should be carried out with actellik solution (0.15% at the rate of up to 2 milliliters per liter can of water).
Scabbards - with such a lesion, brown plaques form on top of the leaves and stem, sucking out the cell sap from the monstera. In this case, the leaves dry out, lose color and fall off. To cure a plant, you need to carry out the same measures as when fighting a spider mite. You can also try wiping the affected leaves with a solution prepared according to this recipe: mix liquid soap (20 grams) with alcohol (1 teaspoon) and warm water (1 liter). Leaves should be wiped on both sides every other day.
Aphids - the presence of such a pest can be determined by the curvature of the tops and the stickiness of the leaves. Then black fungi may appear on the plant, interfering with the process of photosynthesis. The rate of destruction of aphids is rapid. To combat effectively use this recipe: boil 20 grams of mustard powder with boiling water, let it brew. Spray the leaves and stem of Monstera with this solution. Shows itself well in the fight against aphids and a decoction of garlic or onion peel, which should also regularly spray the bush.
Thrips - the appearance of this pest provokes heat environment coupled with low air humidity. Typically on lower parts leaves appear numerous colonies of thrips, and on the upper ones - light dots. As a result of damage, the upper surface of the leaves acquires a brownish-gray tint and a characteristic silvery sheen. To cure Monstera, you should spray the bush with insecticides (intra-vir, phytoderm, actellik, decis).
Mealybugs - this disease affects the shoots and young leaves of the plant. The leaves dry, bend and fall off, and the plant gradually dies. Measures to combat this phenomenon are identical to the methods of getting rid of Monstera from a spider mite.
