Why do avocados turn black and dry leaves?

Externally, avocado looks like a strong fruit and resistant plant. It seems that it successfully confronts any negative manifestations. In fact, this opinion is not entirely correct.

It turns out that avocados are so delicate and susceptible to various changes or diseases that they immediately react to external stimuli by starting to fade, lose their attractiveness, and may even die. It remains only to wonder why this is happening, because all the care instructions are followed, care was decent.

Subtleties of proper care

Avocados, or, as he was given another name - Perseus American, the plant is not so small, and it is often a mistake to plant it in a small pot. Gradually growing up, the roots become crowded. Outwardly, this is still imperceptible, but the root system begins to deform, like the crown, and then one after the other the leaves dry and fall. This can be prevented by transplanting the plant in time in a spacious container.

The temperature in the room where the avocado is located should not be very cold. But the plant does not tolerate too hot temperature either. Required plant and the percentage of moisture. It is most comfortable for him, considering that his native place is a tropical zone, where humidity is elevated, then the leaves will never dry, but, on the contrary, will acquire rich, vibrant colors. To create such conditions, you will need to put moss in the pan - you can buy it in flower shops, or expanded clay. It will be necessary to ensure that there is water in the pan, a small amount. Such a procedure as spraying water on the leaves and around in the air also has a beneficial effect on the plant.

Watering Persei American is a whole science. The plant requires moisture only when necessary, but watering should be moderate, since the soil should not dry out, but too much moisture can adversely affect the health of the plant.

Disease control

Avocados have enemies - small but very serious pests. In the first place - powdery mildew. In fact, it is a fungus that, penetrating the leaves, covers them with a whitish bloom, very much like mold. The first leaves to take the brunt. They begin to turn yellow, and then fall down. If new leaves appear, they acquire a deformed shape. Soon the tree may die.

Most often, the cause of the disease lies in the wrong watering, when the moisture is too much, or very little. Therefore, it is impossible to leave the plant in open space when the long rainy season has begun or the air temperature has been reduced to 15-degree heat.

The plants quickly become infected with this disease from each other, therefore, having found signs of powdery mildew in any plant, it must be immediately isolated.

To combat the disease, experts advise:

1. The leaves affected by the fungus should be removed and preferably burned.
2. Remove the top layer of soil, replacing it with a new one.
3. Spray the trunk and leaves with an effective preparation.Help manganese solution, mustard or soap-soda.

After curing the plant, you need to check the state of the foliage - the disease can come back. If the raid has disappeared about itself, it will usually not return anymore.

A spider mite or scythe can strike a plant. They multiply very quickly, settling on the trunk and on the leaves. If you miss the entry of parasites, the plant can be lost in a short time. You can notice that avocados start to hurt, you can by the color of the leaves: they become yellow and not so hard, and then begin to fall off.

Dry air in the room is especially dangerous during this period, since parasites reproduce more easily and quickly in such conditions. Therefore it is imperative that, starting with them fighting, the air should be moistened.

Each plant, located next to the infected, may be attacked by shchitovki and tick, which means - they must be temporarily carried away from the premises to another place. Infection can occur through the air, often a person caring for plants, inadvertently carries dangerous pests on his hands or tools to care for plants.

To get rid of these parasites will need:

1. Against shchitovki - a soap solution.In the hardware store should buy tar soap, dissolve it in water. So periodically, it is necessary to wipe the leaves using a cotton fiber cloth.
2. Against spider mites will help avermekatiny. Actofit or vermitek has an effective effect.

When the upper leaves deteriorate, it means that the Perseus of American moisture is not enough, the air is too dry, and the watering is insufficient. It happens that watering is in line with the norm, and the top of the plant turns yellow, the leaves fall off. So, all the same watering will require more intensive. During this procedure, it is necessary to moisten not only the soil, but all parts of the plant - the trunk and leaves. The room in which the avocado grows needs to be aired, especiallyif the weather is wet, but it cannot be left in a draft because the plant does not tolerate wind currents and temperature differences. The easiest way to rid the plant of dryness is to place a container with water not far from it.

Dryness can be caused by improperly chosen fertilizers. A large amount of chemistry can damage the roots, because it is better to choose fertilizers with natural ingredients.
