The orchid is considered one of the most beautiful indoor plants, which comes from exotic countries, but it has taken root quite well at home. In order for the plant to please with its flowers, it is necessary to provide competent care, which will be considered optimal for the growth and development of the flower. If this is not done, then the plant will hurt, the leaves will begin to become stained, the peduncle will turn yellow, and the roots will begin to rot.

Particular attention should be paid to the roots. A change in the color of the vegetative organ of a plant may indicate a disease, which means that it is necessary to immediately take measures to save the flower.

Are green roots an indicator of plant health?

It is the roots that will be the main indicator of the health of the orchid. If the plant develops normally, then the root system will be dense, elastic, and the roots will turn light green after watering. There are certain types of orchids, they have dark roots from nature.

Many types of orchids have long enough roots, as they need to cling to trees or stones. All nutrients for growth, the flower takes from water and air. Sometimes the color of the roots has a light green color due to the fact that the surface of each root is covered with velamen - this is a spongy tissue with keratinized cells.

Reference! Ideally, a healthy root has a growing tip and a light green velamen.

It is advisable to ensure that the roots fully fill the entire space of the pot. Due to the roots, the plant is kept, so if the root system is shaky, then you should take care of building up the roots. The roots in the pot of a healthy plant are bright green, and those that are airy are lighter in color.

Why did you change the color and what to do?

For orchids, the normal root color is green. Any modifications are indicative of serious illness. Abnormal color includes:

  • brown;
  • light yellow;
  • white.

First of all, it is worth determining what state the root is in. In a healthy plant, the root changes shape when pressed, and in a diseased plant, the roots are easily pressed, inside they may be hollow or be soft and lethargic.

The main reasons for the changes are related to the following:

  • The roots of the flower do not receive enough moisture, and for a plant that is accustomed to hot and at the same time humid conditions, this is destructive.
  • In exotic countries, where the color comes from, there is enough light, so the flower needs to provide good lighting.
  • You should carefully monitor the size of the pot, too large a pot for a plant with an undeveloped root system leads to its death. Conversely, when a flower is in a small pot and the roots come out, this can also cause its death.
  • Mechanical damage to the roots leads to their discoloration.
  • It is also important to consider the quality of the water used for irrigation; it should not be too hard.
  • Damage to orchids by infections.
  • It should not be ruled out that the roots may change their color due to the fact that the plant is aging, this process is considered quite natural.

In any case, you should find out the exact reason and try to save the flower.

Became white: what to do?

Most often, the roots turn white if unfiltered water is used to water the plant. A change occurs in the soil, a lot of salts begin to accumulate there, which change the composition, and this adversely affects the penetration of air. Such a white bloom can be present not only on the roots, but also in the soil.

If such a situation arises, then it is worth taking the following measures:

  1. Rinse the flower directly in the pot under running water.
  2. Remove the roots that have been damaged, if any.
  3. Change the substrate.
  4. Moisten it with filtered water only.

To preserve the root system of the plant, you can use melt water or rainwater. Some orchid growers recommend softening the water with two drops of lemon juice.

Turned brown: what's the matter?

It is not uncommon for the roots of an orchid to acquire a brown tint. If the roots have changed their color, then you should pay attention to the conditions for keeping the flower. Often the brown color of the roots is a sign that the flower has been improperly planted, for example, very deep. The root system of orchids actively participates in photosynthesis, therefore, during planting, the pigment that is responsible for the green color cannot be produced.

To save the plant, you should apply the following measures:

  1. We remove the orchid from the flowerpot.
  2. The roots are washed gently under running water.
  3. They will definitely need to dry out.
  4. If there are roots that are empty or completely dry, then they must be removed.
  5. The plant is transplanted into a transparent pot and placed in a well-lit place.
  6. Care must be taken not to have too much water in the pot, as the roots can turn brown from rot.

    Important! If the plant has brown roots, then it is worth paying attention to the color of the leaves, brown spots can be located along them, they indicate that the flower is affected by brown rot.

  7. A diseased plant must be removed from healthy flowers.
  8. Remove all affected areas on the plant, and treat the soil itself with a special preparation "Fundazol". You can even use dipping the plant pot in a chemical mixture. The procedure should be repeated three times, after two weeks.

The roots are still green, but the plant has withered and the leaves are withered

It also happens that the flower itself has wilted, but the roots remain green with all this. Do not rush to throw out the plant, it can still be saved. Leaves can wilt if the plant is improperly grown.

  • For example, even cold air from a window can have a detrimental effect on leaves. With hypothermia, the plant sheds all flowers and leaves. It is hardly possible to save the leaves, but you can always try to revive the flower.

    The wilted leaves must be removed, but the orchid itself should not be transplanted. It is enough to rearrange it to a place that will be warmer, away from the draft.

  • The second reason for the wilting of leaves and flowers is too much moisture. In this case, the plant is damaged by rot, so the leaves lose their elasticity.
    1. In this case, you will need to remove the plant from the pot, remove the damaged areas, rinse the roots well under running water and leave to dry well overnight.
    2. Next, the orchid is transplanted into a new soil.

    Watering should be monitored, and carried out only when the soil dries up.

  • The orchid can be damaged by fungus. In this case, it is necessary to act as quickly as possible:
    1. a diseased plant should be set aside from other flowers;
    2. and spray the soil and the orchid itself with a fungicide solution.

It also happens that the exact cause of the wilting of the flower cannot be established. In this case, experts recommend placing the plant in a special greenhouse, where the temperature will be at least + 25 ° C and the humidity is about 70%. The resuscitation of the plant will not occur quickly, but after a while it will be possible to notice that new leaves appear, and the roots become green and elastic.

Despite the fact that this exotic plant is quite capricious, with proper care it grows very quickly and blooms beautifully.

In fact, there are no difficulties in caring for an orchid, you should only carefully monitor all the changes and take action at the time. For example, seeing that the roots of a plant grow in different directions, one can conclude that it lacks heat and sun, and there may be a problem with a lack of water. If the roots are directed upwards, then the plant does not have enough oxygen.
