Through the roots of the plant, they receive nutrients, moisture, necessary for life and development.
Therefore, their diseases quickly lead to the death of the body. In orchids, the roots are highly rotting. If a disease is detected, it is necessary to quickly carry out medical measures.
This article describes how to save an orchid that has rotted roots and how to treat it from rotting.
Why does it rot and why is it dangerous?
Root decay is associated with improper care. Unfavorable conditions of detention lead to the development of fungi and bacteria on the roots. They penetrate the protective membrane and destroy the inner cells. A slight disruption of care and damage to small roots is enough for the disease to begin to spread throughout the entire root system.
If you do not help the orchid, then rotting will destroy the entire root system, this will cause the death of the green pet. To save the plant, it is necessary to eliminate the cause of the disease and carry out a therapeutic measure.
With weak orchid immunity, rot can completely destroy the roots in a few days. Therefore, when it is detected, therapeutic measures must be carried out urgently.
Orchid rot can be caused by various reasons:
- Excess watering leads to a deterioration in the respiration of the roots, they die, rot appears. Rotting gradually spreads to large organs.
- Lack of sun reduces the plant's need for moisture, which leads to the same consequences as overflow.
- Dense substrate impairs root respiration, as does excessive watering. Any mixture hardens over time, which leads to the appearance of decay.
- Chemical burn entails damage to the root shell. It is a consequence of an increase in the concentration of mineral fertilizers in the fertilizing solution.
- Mechanical damage to the roots due to a fall, pests cause the death of a part of the root system and "open the gate" to infections.
To save the orchid, it is necessary to remove the cause of rotting:
- rearrange the plant in a bright, safe place;
- reduce watering;
- change the substrate in a timely manner;
- adhere to the dosage when diluting fertilizers.
Otherwise, therapeutic measures will not help.
Fungi and bacteria cause rotting, but they only infect plants if the conditions of detention have been violated. Fungal infections are most commonly associated with transfusion, especially when there is a lack of lighting.
When watering, moisture enters the velamen, but is not absorbed by the exoderm. A favorable environment is created for the development of fungi. Some species take as little as six hours to start eating away at the root. The mycelium grows throughout all organs of the orchid, penetrates the stem and leaves.
Many spores of rotting fungi are all around us. They belong to the natural soil flora. Without overflow, most fungal organisms are harmless. Only excess moisture makes them dangerous.
How do you know that the rhizomes have begun to deteriorate and that resuscitation is needed?
Root system problems affect the entire plant. Root decay can be suspected by the following signs:
- the leaves turn yellow, become covered with brown spots, become lethargic and die one by one;
- buds and flowers fall off quickly;
- the stem wobbles a lot when the pot is moved.
When these symptoms appear, you need to check the condition of the root system. To do this, the plant is removed from the pot and examined:
- Healthy roots are whitish or greenish in color and have a dense elastic texture.
- Rotting leads to a change in color and density. The roots turn black or brown, and easily wrinkle when pressed. If you run your fingers along the root, then the hands will get dirty in the black-brown mass, and only the inner vein, which looks like a thread, will remain from the root.
Below you will see what decayed roots look like:
How to gradually reanimate a purchased flower that dies?
How to save an orchid, if all its roots are rotten, is it possible to do this, and what to do for this, is considered further. Even if the root system is completely rotten, the plant can be saved. The first step is to remove diseased roots. This is done in several stages.
Removing the substrate
- To remove the substrate, the orchid is pulled out of the pot.
- Gently shake the plant until large clumps fall off.
- Residues are removed with water.
Before the procedure, the roots are placed in a bowl of water for 10-15 minutes. After that, you can proceed to the final removal of the substrate:
- The orchid is taken by the stem so that the roots remain in the basin.
- The fingers of the second hand are placed between the roots, and gently move them, slightly pushing the braided roots.
- Small pieces are washed off with a shower. To do this, you need to adjust the pressure of the jet so that it does not tear the roots, but cleanses off the dirt.
Some roots may leave some substrate after flushing. It cannot be brushed off by hand. Anything that has not been removed by a stream of water is left.
Removing diseased roots
What to do with rotting roots? All rotten roots are removed with garden shears or a sharp knife:
- The cut is made on living tissue, at least 3 cm above the lesion site.
- After pruning, the orchid is left in the air for at least 2-3 hours so that the damaged areas heal.
- A dried wound is treated with crushed activated carbon, wood ash or ground cinnamon. This will prevent infection from entering the damaged area.
After pruning, the orchid can be immediately revived in a greenhouse or in other ways, but it is better to use additional processing first.
Treatment with growth stimulants
Rotting is always associated with the appearance of a fungus, therefore before planting, the roots are treated twice, with a week break. Can be used:
Additionally, succinic acid is added to the solution with each soaking, Epin or Zircon - once every 2-3 weeks.
While the antifungal treatment is being carried out, the flower is not planted in the substrate. To prevent the root system from drying out, it is periodically sprayed from a spray bottle. Succinic acid can be added to the water, 1 tablet per liter of water, it is a natural and safe growth stimulant.
When revitalizing without a substrate, you can combine root germination and treatment with fungicides and biostimulants.
What to do to save the plant at home, if all the roots are rotten, but sluggish leaves remain?
What if you flooded the plant and did not notice that the roots began to rot, but they completely rotted, and only the outlet remained? In this case, before planting in the substrate, it is necessary to provide the orchid with special conditions so that it can restore the root system at least partially. Otherwise, the plant's chances of survival are minimal. Without roots, soil fungi will begin to infect the stem and leaves (why does an orchid leaf rot?). Several methods are used for germination, the choice depends on the state of the indoor flower.
In the greenhouse
To restore orchids that have completely rotted roots, a window greenhouse is used. You can make it yourself. It is necessary to make a frame in the form of a deep box and cover it with polyethylene on five sides. The bottom is left open.
When you need to care for a sick orchid, the box is lifted, therapeutic measures are carried out and put back.
For small specimens, you can create a greenhouse from any transparent container:
- a plastic bottle;
- cake lids;
- glass jars.
Creating a greenhouse effect greatly increases the plant's chances of survival. Warm humid air stimulates root formation, but prevents moisture from accumulating in the velamen.
A sick orchid is planted in a special container filled with expanded clay 2-3 cm, sprinkled with moss on top. The substrate is periodically sprayed from a spray bottle. To increase humidity, you can put a container of water next to the affected plant. The orchid is kept in a greenhouse until 4-5 cm roots appear, usually 2-3 weeks.
The greenhouse method gives the best results in the restoration of the root system.
Without a greenhouse
If there is no greenhouse, the roots have completely rotted, and only leaves remain, then you can try to save the plant in indoor conditions:
- To do this, use a deep container: a jar or glass with a narrow bottom. Boiled or distilled water is poured into it, into which an activated carbon tablet is thrown.
- Place the flower in a container.
- The liquid level is adjusted so that it reaches the root collar of the rosette.
- The orchid is kept above water for 10 hours, after which it is planted in a container with moss.
The flower is sprayed every day until the roots sprout.
We offer you to watch a video about the resuscitation of an orchid whose roots have rotted by transplanting it into a container with water:
By planting in a regular substrate
If the orchid has at least a few roots of 3-5 cm, it can be immediately planted in a substrate with a large bark. Until the beauty gets stronger, she needs a small pot, 8 cm.
How to care to keep?
When revitalized in any way, plants are provided with ideal environmental conditions: twelve hour daylight hours, diffused lighting and an air temperature of 20-27 degrees. During the restoration of the root system:
- Reduce the amount of nitrogen in top dressing.
- If the flower does not have enough moisture, and the leaves lose their turgor, they are sprayed.
- Provide regular, but scanty watering.
In a favorable environment, the orchid will begin to grow roots almost immediately after transplanting. Small flowers will restore the root system in 2-3 months, large specimens will need about six months. Until the health of the plant is restored, it will not grow and bloom.
Prevention of spoilage
In order to prevent repeated root rotting, it is enough to create favorable conditions for the flower:
- temperature 20-27 degrees;
- good lighting;
- moderate watering;
- well ventilated substrate.
No additional preventive measures need to be taken.
Plants accumulate nutrients in:
We recommend that you look at our other articles on what to do with a flower if the core, orchid leaf rot, and how to recognize and treat fusarium.
They are able to recover even after severe damage to any organs. However, do not overuse the vitality of orchids. Revitalization is a complex and lengthy process. Until the plant gets stronger, it will not delight with flowers.
