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 whengrowing a plant and the fact that the juice of the culture consists of harmful toxins that can adversely affect the mucous membrane of various human organs and systems. So that you never have a question about what to do with brown spots on anthurium leaves, you should follow some rules for growing this plant. Care features are as follows:
- It is recommended to grow a flower in partial shade or on a windowsill, where there is diffused light, since anthurium does not like bright lighting. At the same time, in winter it is important to provide artificial additional lighting to the anthurium. If this is not done, then the plant will not be able to produce flower stalks.
- In summer, the air temperature in the room should not be more than 25 degrees Celsius, and with the advent of winter, the plant can develop even at an air temperature of 14-16 degrees above zero.
- In order for the anthurium flower not to die, you should avoid places where there are drafts.
- 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 advent of winter - 1 time per week. The remaining water after watering from the pan must be poured out, otherwise the roots will begin to rot.
- You should also ensure good humidity in the room. Leaves should be sprayed systematically, but this should be done so that water does not get on the flowers.
- Twice a month, feed the anthurium, using a mineral solution or organic fertilizers for this purpose. It is necessary to feed during its flowering, as well as activegrowth of anthurium.
- It would 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 purchasing an anthurium in a store, it must be transplanted into another container that is suitable in size with the right substrate.
At home, the plant can be propagated by cuttings. Cuttings for this are cut from the tops of the flower with aerial roots. Planted according to the rules in pre-prepared containers. But how to avoid brown spots on anthurium leaves? What to do? It must also be protected from attack by various insects: scale insects, aphids, fungal infections.
Why do brown spots appear on anthurium leaves?
If mistakes are made with watering, the feeding schedule will be disrupted, the room will have very dry air, improper lighting, then the leaves of the plant will gradually begin to dry. When brown spots appeared on the leaves on the anthurium, the reason for this may be a sharp temperature drop, growing the plant in a cold room. If the characteristics of growing are violated, 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 plates become brown due to lack of nitrogen, potassium, phosphorus, calcium or magnesium. It is recommended to feed a houseplant with ready-made liquid products. The affected anthurium is fed once a week. When the flower gains strength again, top dressing is reduced to once every 2 weeks. With an excess of fertilizer, brown dry spots can also form on the leaves of the anthurium. To save the flower, you need 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;
- inadequate air temperature;
- a large amount of calcium s alts in the soil.
Why does Anthurium have brown and black spots on its leaves? If such a dark brown, almost black coating on the leaves arose due to an excess of calcium s alts in the soil, then it is necessary to replace the soil containing humus and peat. After that, the flower is watered with softened water.
If the leaves of the anthurium began to turn black due to drafts, then the pot must be moved to another place. In the case of blackening of the leaf plates due to direct sunlight, it is necessary to make a shaded place for the plant. It is also important to provide the pot with more diffused light or partial shade.
Pests
We continue to consider why the leaves of anthurium are covered with brown spots. If the leaves are covered with lightbrown, yellow spots, began to curl up, this indicates that the aphid attacked the flower. If you want to save the plant, it must be treated with special means or tobacco tincture.
If the shoots are covered with cracks, and the leaves are stained, then a mealybug attacked the flower. To combat it, karbofos is used. Dark brown spots on the leaves appear due to the attack of the scale insect. Such pests must be removed manually, and the flower should be treated with a solution of laundry soap and kerosene.
Brown spots
Brown spots on anthurium leaves, photos of which are presented in our article, may occur due to reasons:
- Wrong feeding. It is necessary to fertilize with fertilizers with a balanced composition.
- When the temperature is low, the leaves become covered with small brown dots.
If you notice brown spots on anthurium leaves, the reason may be that the flower stem may have suffered from a pest such as a mealy worm, which can be destroyed with special preparations sold in flower shops.
Yellow Spots
Leaves turn yellow in winter due to lack of light. Also, watering with chlorine, as well as heavy metal oxides, can lead to this phenomenon. If you want to avoid yellowness, it is recommended to water the plant with rain, melt or pre-settled water at room temperature. If water accumulates in the pan, the roots will begin to rot and the leaves will turn yellow. Need to keep the soil moistmoderately, remove excess liquid from the pan. A flower in a small pot can also produce yellow leaves. Then it must be transplanted into the largest container.
Leaves dry up
Anthurium leaves dry due to too dry air, poor watering, diseases, aphids. The frequency of watering will depend on the season. The soil between waterings should dry out by about a third of the pot. To increase the humidity of the air, spray the leaves daily with water. When the leaves dry out at the edges, and then dry completely, it means that the flower has suffered from anthracnose. Treat the plant with a systemic fungicide to control the disease.
Dried tips can form due to lack of oxygen directly in the root system. Transplant the anthurium into soil with cones or charcoal.
Flower age
Most often the leaves turn yellow due to aging. Age change affects more those foliage, which is located closer to the soil surface. At the same time, yellowness spreads throughout the leaf, due to which elasticity, juiciness are lost, the leaves become brown. After some time, they disappear on their own, if they are not removed earlier. If the plant is well, properly cared for, the loss of old foliage will not harm the flower, because he althy young leaves will begin to grow at the top.
Yellowing leaves do not benefit the plant, they 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, becomeattractive. To cut the leaves that have become obsolete, it is recommended to use scissors or a knife treated with alcohol so that the infection does not enter the stem. Sprinkle the cut place on the trunk with crushed charcoal. When the leaves have turned yellow, but have not lost their juiciness, they cannot be cut off manually so as not to injure the main stem, so use a sharp tool for this purpose.
Other possible problems when growing the plant
The size of the leaf blades and flowers will be affected by the age of the anthurium. The older the plant, the smaller, paler the flowers will be. Every year the trunk becomes more bare, because the leaves from below die off. Some varieties continue to grow luxuriantly but with small rosettes, and some with only one rosette.
To help the flower continue to bloom profusely with large flowers, you need to rejuvenate it. To do this, with a sharp knife, cut off the top of the plant in such a way that a stalk with two or three aerial roots is obtained. Plant it in prepared soil. In order for it to develop better, it can be placed before planting in a growth stimulator. You need to take care of the cutting systematically, spray it with warm water. Often flower growers are faced with such a problem - the anthurium both dries up and does not bloom. This problem is usually caused by:
- lack of lighting;
- inappropriate temperature conditions;
- high temperatures in winter;
- wrong watering;
- low air humidity;
- dry inflorescences on the plant.
If you want to return flowering to the plant, it is recommended to change the conditions of detention, remove the inflorescences after they begin to wither.
