Brown spots on the leaves are often found in an anthurium indoor plant. What to do in this case? Before answering this question, it should be noted that this phenomenon is considered a very bad sign for culture, because Anthurium is a luxurious indoor plant, which has shiny weighty green plates, beautiful flowers. That is why it will be important to know what to do with brown spots on the leaves of anthurium, why they appear, how in the future this problem can be prevented. We will talk about this in the article.
Features of plant care and cultivation
Anthurium is a very capricious plant regarding care and maintenance. Some species are grown exclusively in greenhouses. It is also important to take into account during plant growth the fact that the juice of the culture consists of harmful toxins that can adversely affect the mucous membrane of various organs and systems of a person. So that you never have a question about what to do with brown spots on the leaves of anthurium, you should follow some rules for growing this plant. Features of care are as follows:
- It is recommended to grow the flower in partial shade or on the windowsill, where there is diffused light, since the anthurium does not like bright lighting. At the same time, it is important to provide the anthurium with artificial additional lighting. If this is not done, then the plant will not be able to produce peduncles.
- During the summer period, the air temperature in the room should not be more than 25 degrees Celsius, and with the advent of winter, the plant can also develop at an air temperature of 14-16 degrees above zero.
- In order for the anthurium flower not to die, places where there are drafts should be avoided.
- It is recommended to water the plant with a little warm water. In summer, watering is carried out 1 time every three days, and with the arrival of winter - 1 time per week. After watering from the pan, the remaining water must be poured out, otherwise the roots will begin to rot.
- You should also provide good humidity in the room. Leaves should be systematically sprayed, but this should be done so that water does not get on the flowers.
- Twice a month to feed Anthurium using mineral solution or organic fertilizers for this purpose. It is necessary to feed during its flowering, as well as the active growth of anthurium.
- It will be better if the anthurium grows in self-made soil. To do this, mix humus (2 parts) with leafy soil and peat (1 part each), with sand (0.5 parts). Add crushed brick or cones as a drainage layer.
- It is important to note that after acquiring an anthurium in a store, it must be transplanted into another container of suitable size with the correct substrate.
At home, the plant can be propagated by cuttings. Cuttings for this are cut from the tops of the flower with aerial roots. Landed according to the rules in pre-prepared containers. But how to avoid brown spots on the leaves of anthurium? What to do? It must also be protected from attack by various insects: scale insects, aphids, fungal infections.
Why do brown spots appear on the leaves of anthurium?
If mistakes are made with watering, the feeding schedule is violated, the room will have very dry air, improper lighting, then the leaves of the plant will gradually begin to dry. When brown spots on the leaves appeared on the anthurium, the cause of this may be a sharp temperature drop, growing the plant in a cold room. In case of violation of the cultivation characteristics, the flower begins to hurt, it may even die. Therefore, it will be important to know the main reasons due to which brown spots or spots of a different color appear on the leaves of anthurium.
Wrong fertilizer
If there is a lack of nutrients and elements, then slow growth is noted, young small leaves. Leaf blades become brown due to a lack of nitrogen, potassium, phosphorus, calcium or magnesium. It is recommended to feed an indoor plant with prepared liquid means. The affected anthurium is fed once a week. When the flower regains strength, top dressing is reduced to once every 2 weeks. With an excess of fertilizers, brown dry spots can also form on the leaves of the anthurium on the leaves. To save a flower, it is necessary to transplant it into a new soil, washing the roots.
Black leaves
The following reasons can lead to blackening of leaf plates in anthurium:
- direct sunlight;
- drafts;
- inappropriate air temperature;
- a large amount of calcium salts in the soil.
Why does the anthurium have brown spots and black spots on the leaves? If such a dark brown, almost black coating on the leaves occurred due to an excess of calcium salts in the soil, then soil containing humus and peat should be replaced. After that, the flower is watered with softened water.
If the anthurium began to turn black leaves due to drafts, then the pot needs to be moved to another place. In case of blackening of the leaf plates due to direct sunlight, a shaded area should be made for the plant. It is also important to provide the pot with more diffuse light or partial shade.
Pests
We continue to consider why the leaves of the anthurium are covered with brown spots. If the leaves are covered with light brown, yellow spots, began to curl, then this indicates that the aphid attacked the flower. If you want to save the plant, it must be treated with special means or tincture of tobacco.
If the shoots were covered with cracks, and the leaves were stained, then the mealybug attacked the flower. To combat it, kalbofos is used. Dark brown spots on the leaves appear due to a scale attack. Such pests must be removed manually, and the flower is treated with a solution of laundry soap and kerosene.
Brown spots
Brown spots on the leaves of anthurium, photos of which are presented in our article, may occur due to reasons:
- Incorrect feeding. Fertilize with fertilizers with a balanced composition.
- At low temperatures, the leaves are covered with small brown dots.
If you notice brown spots on the leaves of the anthurium, the reason may be that the flower stem may have suffered from a pest such as a powdery worm, which can be destroyed with special preparations sold in flower shops.
Yellow spots
Leaves turn yellow in winter due to lack of light. Watering with chlorine, as well as heavy metal oxides can also lead to this phenomenon. If you want to avoid yellowness, it is recommended to water the plant with rain, melt or previously defended water at room temperature. If water accumulates in the pan, the roots will begin to rot and the leaves will turn yellow. It is necessary to moisten the soil moderately, remove excess fluid from the pallet. A flower in a small pot can also produce yellow leaves. Then it must be transplanted into the largest capacity.
The leaves are dry
Anthurium leaves dry due to too dry air, poor watering, diseases, aphids. The frequency of watering will depend on the time of year. The soil between waterings should dry by about a third of the pot. To increase air humidity, spray leaves daily with water. When the leaves dry at the edges, and then completely dry, then the flower suffered from anthracnose. To combat the disease, treat the plant with a systemic fungicide.
Dried tips can form due to a lack of oxygen directly in the root system. Transplant anthurium into the ground with cones or charcoal.
Flower age
Most often, the leaves turn yellow due to aging. Age-related changes affect more the foliage, which is located closer to the soil surface. At the same time, yellowness spreads throughout the sheet, due to which elasticity, juiciness is lost, the leaves become brown. After some time, they disappear on their own, if they are not removed before. If the plant is well, properly maintained, the loss of old foliage will not harm the flower, because at the top healthy young leaves will begin to grow.
Yellowing leaves do not benefit the plant, only take away its strength, it is better to cut them off in time. If you remove the old leaves, then the flower will begin to develop, it will become attractive. To cut off the obsolete leaves, it is recommended to use scissors or a knife treated with alcohol so as not to bring the infection into the stem. Sprinkle the cut-off place on the trunk with chopped charcoal. When the leaves are yellowed, but have not lost their juiciness, they can not be torn off manually so as not to injure the main stem, so use a sharp tool for this purpose.
Other possible problems when growing a plant
The size of leaf plates and flowers will be affected by the age of anthurium. The older the plant, the smaller, paler the flowers will be. Each year, the trunk becomes more exposed, because the leaves from below die off. Some species continue to grow splendidly, but with small outlets, and some with only one outlet.
To help the flower still bloom profusely with large flowers, you need to rejuvenate it. To do this, cut off the top of the plant with a sharp knife so that a little cut with two to three airy roots is obtained. Plant it in the prepared soil. So that it develops better, it can be put before planting in a growth stimulator. The cuttings must be looked after systematically, sprayed with warm water. Often, flower growers encounter such a problem - the anthurium dries and does not bloom. As a rule, this problem leads to:
- lack of lighting;
- inappropriate temperature conditions;
- high temperature in winter;
- improper watering;
- low humidity;
- dry inflorescences on the plant.
If you want to return flowering to a plant, it is recommended to change the conditions of detention, to remove inflorescences after they begin to wither.
