How to save the neck from gray and root rot and what to do if the roots of the phalaenopsis orchid rot?

Indoor flowers are living things. They are susceptible to many diseases, in particular rot. Even if there are no harmful insects in the room, the risk is great enough.

Healthy plant development is possible only while maintaining optimal parameters.

So, from the article you will learn what rot is, what parts of the plant it affects, as well as how to deal with it and which preventive measures to take.

What is rot?

Rot is a general definition of diseases caused by phytopathogenic fungi and bacteria. Rotting Damage to Leaf Blades, a more advanced process - to complete decay, drying out and rather soon death of decorative flowers. Plants that are affected by rot become weak, wilted, lose turgor, decorative qualities deteriorate, flowering time decreases, photosynthesis processes are often hindered, and growth stops.

Attention! With an excess of humidity in the room, the affected areas of the plant are overgrown with spores of rot, which can spread to nearby flowers.

Which parts of the plant are more susceptible?

First of all, young leaves, flowers, buds suffer from rot. Then the process of decay spreads, moving on to the next stage, decay. At this stage, the leaves lose their elasticity, bright color, tone. The disease affects the stem and root system (what other diseases affect phalaenopsis?). With subsequent development, parts of the plant become covered with mold, becoming soft, and then die.

How to define this process?

The presence of rot on orchids is determined based on the presence of the following symptoms:

• discoloration of the root system, noticeably darkens;
• when you click on the root - a liquid appears;
• foliage loses its elasticity (why else can the leaves fade?);
• the presence of weeping areas on the rhizome;
• greenish traces of sporulation can be seen on the walls of the pot;
• shaky, unstable upper part of the plant.

Effects

Phalaenopsis, damaged by rot, begins to lose foliage (what are the diseases of phalaenopsis leaves?). Leaves become soft, less resilient. They fall off the stem, the plant develops like a constructor. At the initial stages of decay, it will turn out to revive the roots (how to save a flower without roots?). The main thing is to detect the disease in time, urgently take all necessary measures, and eliminate the cause of the spread of rot. Only in this way, the orchid can be saved from imminent death. After all, in the later stages nothing will help.

Drugs to combat this ailment

The most effective drugs for the prevention and treatment of the process of decay are considered fungicides. These are funds that eliminate the causative agents of fungal diseases in representatives of the flora. Components of fungicides are: copper, manganese, mercury, organic substances and aldehydes. To eliminate rot in phalaenopsis, apply:

1. Fitosporin-M suitable for the treatment of fungal and bacterial diseases.
2. Quadrix - a broad-spectrum preparation, made on the basis of the substance azoxystrobin, is used for prophylactic and treated purposes.
3. Blue vitriol based on copper sulfate, a positive effect is observed after 3 hours.
4. Mikosan useful in the initial stages of the development of the disease, activates the work of lectins, stimulates the immune system.
5. Bordeaux liquid also made on the basis of a solution of copper. Also included is lime to lower the acidity of the soil.

What to do in this case: instructions on how to destroy the disease

Help orchid, which has lost the rhizome

In fact, tropical beauties are tenacious flowers. Even if the root system rotted, the plant may well exist further. Emergency measures must be taken.

2. Slice sites are treated with antiseptic agents that do not contain alcohol. Often used crushed activated carbon, ground cinnamon. Leave to dry for several hours. After treat with a fungicide solution, to surely get rid of the harmful fungus.
3. At the end of the disinfection procedure, the remains of the root system should be dipped in a solution with root stimulants. These drugs increase the immunity of the plant, and accelerate the process of root formation. It is better to take "Epin" or "Zircon", diluting in the following proportions: 1 drop of the drug per 1 liter of water. In this solution, the orchid should be about 2 hours. It is important to ensure that no liquid enters the leaves.
4. Depending on the state of phalaenopsis, it is required to choose a further method of germinating the root system: greenhouse or in the air. If the roots are completely absent, then the first option is the greenhouse. If some of the roots are still there, then you can do without it.
5. Orchid should be placed in a container with purified water. However, regular drying is required, especially by choosing the non-greenhouse method. In both cases, the flower should be in a well-lit place, at a temperature of + 23-25ºС. It is necessary to regularly feed fertilizers based on potassium and phosphorus, 1 time in 10-14 days.Advice! Once a month, use a root stimulant, the time the plant spends in such a solution is no more than 6 hours.
6. The appearance of roots expect from 1 month to six months. The duration of the process is directly related to the initial state of the plant.

Prevention

To avoid such unpleasant situations is possible with proper care of the orchid:

• Maintaining a comfortable temperature in summer: + 22-25ºС, in winter + 16-18ºС. The difference in temperature differences should not exceed 5ºС.
• Lighting is required diffused, with a daylight duration of 14 hours.
• Humidity within 50-60%. Be sure to regularly ventilate the room.
• Water once a week, in between the soil should completely dry.
• It is better to spray Phalaenopsis up to 5 times a day. Exclude the procedure during the flowering period.

The correct content of orchids in room conditions will eliminate the possibility of getting sick with various ailments. It is also important to adjust the care depending on the time of year and on the condition of the plant.
