Mold in a flower pot on the surface of the ground: reasons for how to get rid of it using folk remedies

Quite often, white mold appears on the ground in flower pots, although its color may vary. As a rule, it appears either under the influence of external factors or due to improper care of indoor plants. A white coating appears first at the border of contact between the soil and the pot, and then quite quickly fills the entire space.

This may occur due to the fact that there are fungal spores in the air, which, under certain conditions, begin to multiply rapidly, growing into entire colonies. This is dangerous not only for the plants themselves, but also for the people living in the apartment.

What types of mold grow on soil?

Mold in a flower pot can be different, but mainly the following two types are found on the surface of the earth:

Mucor (lat. Mucor) or white mold. Mushrooms in a flower pot are quite common, especially when it comes to the Mucor variety. This type of mold forms in the upper layers of the soil and looks like white fluff that is easily rubbed in your hands.

Efflorescence (Efflorescence) or white coating of soluble salts. Despite the fact that this type is not at all similar to mold that is familiar to the eye, it can be no less harmful. Salt or alkaline plaque, unlike white mold in the form of fluff (Mukora), affects the ground surface, as well as internal areas. Efflorescence (Efflorescence) looks like a crystalline coating of white or gray color (but can sometimes have a greenish tint).

Another fairly common ailment of indoor plants is “root rot” or, as it is also called, “black leg”. It lives deep in the soil and does not show itself on the surface, like Mukor or Vysol. Despite this, its presence can still be determined. The leaves of plants affected by root rot curl, turn black, and rot.

It is advisable to get rid of root rot as soon as possible, because in this case there will be a much greater chance of saving your favorite flowers.

Causes of the appearance and spread of fungus

There are several reasons why mold appears in flower pots. For example:

Incorrect watering of plants, which causes liquid to stagnate in the pot.
In conditions of low temperatures and high air humidity.
Watering the plants with cold water.
There is no drainage system in the pot, so the liquid waterlogs the soil.
Application of contaminated soil.

As a rule, the higher the humidity and the lack of air movement, these are conditions for rapid growth of mold. Mold most often appears either in spring or autumn.

This is due to the fact that the average daily temperature does not allow moisture to evaporate quickly, so there is an excess of moisture in the pots of houseplants. And these are conditions for the rapid proliferation of fungal spores.

In addition, increased dampness in the house also contributes to the appearance of mold in flower pots and more. In a damp apartment, when the ventilation system does not function well and air stagnates in hard-to-reach places, mold may appear here. In addition, the location of the apartment plays a big role: if there is a basement underneath it, where there is high humidity, this will certainly affect the microclimate of the apartment.

HOW TO GET RID OF WHITE POINT IN FLOWER POTS?

Why does the soil in a flower pot become covered with a white coating?

If a white coating appears in a pot with your favorite flower, it means that the plant was most likely not cared for correctly.

Before removing the white coating on the ground in flower pots, you need to find out exactly why it appeared there. Only after this will it be possible to begin creating conditions in which the fungus will not even think about reappearing.

So, the most common causes of mold:

Excessive soil moisture. How often do beginning gardeners fear drying out their flowers, and therefore water them too often and, more importantly, incorrectly. Water, an abundant amount of which enters the plant, actively evaporates, leaving behind salts on the ground surface. What is noteworthy is that salts can accumulate even with poor watering. In this situation, the liquid enters only the top layer of soil. You can fix this as follows:
Dry indoor air, as well as excess humidity, does not have the best effect on indoor plants. It leads to intense evaporation of moisture, as a result of which salts are quickly carried to the surface of the soil. Gradually the ground becomes saline, and the flowers begin to hurt because of this. To prevent such developments, monitor the humidity level - it should be optimal.
A large amount of fertilizers. A white coating appears on the soil of indoor plants when the flower is “overfed” with various useful additives. For indoor plants, you need to choose a special soil that is suitable specifically for them. Houseplants don't need so many additives! It is also important to monitor not only what substances you feed the flower, but also when and how you do it. For example, during the growth period it is necessary to accurately calculate the dosage, but during dormancy it is better to put fertilizers in the far corner and not disturb the plant unnecessarily. Another reason why mold appears in a flower pot on the surface of the ground is too much soil. A miniature plant does not have many needs, so excess soil will only harm it. The small roots of the flower will not be able to completely absorb moisture, and excess liquid, coming to the surface, will lead to the deposition of salts. That is why it is so important for each plant to select a pot that is the right size for it, in which it will sit perfectly. Oh, you also need to monitor the water hardness! For plants, “medium” is recommended, not very hard, but not quite soft either. It is not recommended to water with tap water - let it settle first. Don't forget about the water temperature - it should be room temperature. IMPORTANT! Some people believe that flowers can be planted in any soil, even those intended for vegetables. This judgment is erroneous, because the soil for vegetables is supplied with a large amount of fertilizer in advance.
Processes of a biological nature . In addition to physical processes, there are biological factors that influence the formation of white plaque. One of these factors is fungal microflora, which manifests itself in all its glory, again, from too much watering. It also happens that the purchased land for some reason is already moldy. It may not harm adult plants, but the development of young seedlings in such conditions is endangered. If mold grows throughout the entire depth of the pot, the substrate must be disposed of immediately. Just don’t throw it into your garden! It's better to take it somewhere further away under the fence.

Why is mold dangerous?

Mold is considered quite dangerous for the plant, therefore, it should not be allowed to actively fill the space in the pot, and here’s why:

The plant is sick because mold blocks the access of nutrients to the stems, leaves and flowers.
The access to oxygen to the root system is also blocked.
Mold can cause various diseases.
Since soil moisture is higher than normal, the roots of the plant may simply rot.

If you postpone the fight against the fungus for an indefinite time, the flower will simply die.

Mold in a flower pot, how to get rid of it?

If the soil in the pot smells rotten and is covered with plaque, change the plant's watering schedule by reducing the volume of liquid and reducing the frequency of watering. Some flowers do not need frequent watering and thrive in slightly moist soil. Frequently watering such plants will cause their roots to rot due to fungal infection.

If you water the flowers rarely but abundantly, you will have to additionally loosen the soil. This needs to be done deep enough, but carefully so as not to damage the roots.

You can get rid of the fungus without damaging the flower as follows:

Remove the top layer of soil (if this is not done, the infection will penetrate deeper, the roots will rot, and the plant will die).
Dilute citric acid in a glass of water. Moisten the lower layers of soil with the prepared liquid (the acidic environment does not allow the fungus to multiply).
Replace the removed layer of soil with a new one. Add bactericidal agents to it. Their additional property is to filter components for incoming moisture. It is recommended to add crushed sphagnum (a type of moss that grows in swamps, from which peat is formed) and pieces of charcoal to the soil.
Dilute 2 grams in a liter of water. "Fundazola" (a fungicide that effectively fights diseases of indoor and garden plants). Water the ground with the prepared mixture. If the infection has spread to the plant, carefully treat it with the same solution.
To consolidate the result of the treatment, loosen the top layer of soil from time to time (this way the liquid will not stagnate and will be distributed evenly).

ADDITIONALLY If the soil in the pot becomes covered with white mold again, dissolve half a teaspoon in a glass of water. citric acid and water the flower with the prepared mixture at least 2 times a month.

Transplanting a plant

If mold has appeared in a flower pot and you are thinking about how to get rid of it as quickly and efficiently as possible, a comprehensive plant replantation will help you. When moving a flower to a new pot, completely remove the old soil and add fresh soil. The latter must be chosen taking into account all the nuances (transplantation rules, type of plant and much more). Before you start replanting plants, find out in advance what level of humidity will be most optimal for each of them.

Soil disinfection

To rid the soil of infection and moldy smell, completely disinfect it using the instructions:

Separate the contaminated soil from the plant roots.
Move the soil from the flower pot to another container.
Douse the soil with boiled water.
Place the soil on a baking sheet and bake it in the oven.
Wait until the substrate cools down.
Treat the pot with disinfectants (you can additionally fire it with an open fire if you are dealing with a flower pot, for example).
Fill the soil back into the pot and plant the plant in it.

Purchased funds

You can also eliminate mold using “chemical” products that are sold in flower shops. Before you go shopping, you should find out:

type of soil;
plant characteristics;
degree of spread of the fungus;
what fertilizers were used to cultivate the land.

Be careful! Using the wrong product may have the opposite effect. In some cases, you cannot use chemicals at all to eliminate mold. Preference should be given to organic preparations that affect the soil in such a way that it becomes not the best place for fungal growth.

Folk methods of dealing with various raids

Folk remedies involve the use of safe methods:

Replanting the plant or replacing the top layer of soil.
Using a weak solution of potassium permanganate. This method is effective only against mold, since potassium permanganate has fungicidal (antifungal) properties.

All types of molds, efflorescence, moss, appear on dense, poorly drained soils. Improving the soil structure, loosening, and regulated watering will help prevent this problem.

What to do if a white coating appears on the leaves of a plant?

Powdery mildew (ashtray, white) is a rapidly spreading fungal disease.

The first “symptom” is a white coating on the leaves, which at first glance may seem like ordinary dust. When the leaves are covered with it, the plant loses nutrients and the process of photosynthesis stops.

At first, a white coating appears only on the lower leaves of violets and other plants, but over time the disease progresses, spreading to other parts of the plant. The leaves turn yellow, wither, and new leaves look unhealthy and grow curled.

If you do not treat the plant in time, it will soon die.

For what reasons does the disease occur?

Fungal spores are always present in the soil, but with proper plant care they are not “activated.” The fungus begins to show its evil essence if:

The weather is damp and cool outside

For example, it rains every day. In this case, a white coating on the leaves of ficus and other plants more often appears when they are grown on the street or balcony.

Irrigation schedule is not followed

For example, a white coating on the leaves of begonias and other flowers appears if the plant is watered too often when the top layer of soil has not yet dried.

Or, on the contrary, they dry out the soil and then water it abundantly.

Spores can enter the plant in other ways:

by air (for example, if the wind blew and air currents brought spores from other plants and trees);
with water (for example, if water for irrigation was left in a bucket in an open place, and spores landed in it);
through your hands (for example, if before working with a healthy plant you touched another, infected one).

Prevention.

As part of preventive measures, it is necessary to constantly analyze the condition of the indoor plant, not only the soil, but also its appearance. If mold is detected, you can use certain drugs to prevent this fungal disease. When using medications, follow safety precautions. Since many drugs have a hazard class. And when using some that are prohibited from being used at home, special processing conditions must be observed.

To prevent mold from appearing in your flower pot, monitor the watering schedule and do not overwater your plants. And if some plants require abundant watering, drainage must be maintained in the pot. For preventive purposes, when watering, you can use weak solutions of drugs that are diluted in water for irrigation. And if all these points are observed, problems with mold should not arise. Good luck to you.

How to cure a plant from powdery mildew?

A few recommendations before treatment:

Water the flowers only after the top layer of soil is completely dry.
Do not spray the plant while you are getting rid of powdery mildew.
Place the flower pots in a brighter, sunny place and let them stay there until the disease is completely cured.
Thin out dense plantings, tear off old leaves (especially those that are close to the ground).
During the period of remission, use less nitrogen fertilizers and more phosphorus-potassium fertilizers.

Attention! Avoid any fertilizer while the flower is sick!

Mistakes made in plant care must be corrected, otherwise white plaque on indoor plants will appear again and again.

Now let's move on to the treatment itself.

To get rid of the disease, do the following:

Pick off yellow, affected leaves.
If a white coating appears on the leaves of roses and other bush-type plants, it is advisable to cut off all infected branches - this will increase the chance of cure.
Replace the top layer of soil in a pot, container or under flowers in a flowerbed - it contains “mushroom” colonies or mycelium (mycelium).
Spray and water the plant with a medicinal preparation. During the procedures, make sure that the leaves and shoots are properly moistened.
You can use another method: pour the medicine into a bowl of water and place the bush there.
The soil and pots/containers also need to be treated with the medicine.

Preventative measures to prevent the appearance of mold

The appearance of mold in pots where houseplants are grown can be considered an emergency and a signal that all measures must be taken to prevent the fungus from spreading further. To prevent this from happening, it is better to think about this in advance. For example:

From time to time, loosen the top ball of soil so that it breathes and there is no stagnation of moisture and air.
When planting plants, take care of a normal drainage system.
Grow indoor plants in special pots equipped with holes in the bottom.
Fertilize with wood ash or activated carbon. Don't forget about other actions that can reduce the likelihood of mold growing in flower pots.

For example, you can treat the soil with potassium permanganate at least once a month. In this case, you should prepare a weak solution that will not harm the plants.

Garlic, which needs to be cut into several pieces and placed next to the stem, is considered to be a fairly effective remedy against fungus. This is done before watering, and when the top ball of soil dries, the garlic is removed. It can be used in a rotation of once a week. If mold appears, apply garlic every two days.

Traditional methods

Remedies from this category will work effectively if a white coating has recently appeared on a cactus or other plants (early stages of the disease) or as a preventive measure.

Dissolve 25 g of soda ash and 5 g of liquid soap in 5 liters of hot water. Let the prepared liquid cool. Spray the top layer of soil and the plant with the cooled solution 2-3 times. The interval between spraying is a week.
1 tbsp. l. baking soda and half tsp. Dissolve liquid soap in 4 liters of water. Spray the plant and soil 2-3 times. The interval is 6-7 days.
Dissolve 2.5 g of potassium permanganate in 10 liters of water. Use 2-3 times. The interval is 5 days.
100 g of fresh horsetail pour 1 liter of water. Wait a day. Place on fire and boil for 1-2 hours. Strain, cool, dilute with water (1:5) and treat the bushes. Store the solution for no more than a week in a dark, cool place. Spraying can be carried out regularly as a preventive measure in spring and summer. During the disease (in the early stages), plants are treated 3-4 times. Frequency – once every 5 days.
Dilute 5 g of copper sulfate in 250 ml of hot water. Dissolve 50 g of soap separately in 5 liters of warm water. Pour the solution with vitriol into the soapy liquid in a thin stream, stirring constantly. Spray the plant 2-3 times with the prepared product. The interval is 6-7 days.
1-2 tbsp. l. Pour dry mustard into 10 liters of hot water. Water or spray the plants with the cooled solution.
Stir 1 kg of ash in 10 liters of heated water. Let the solution brew (3-7 days), stir it regularly. Drain the water into a clean container, add a small amount of liquid soap and pour into a spray bottle. Treat plants 3 times every day or every other day. The remaining liquid in a separate container, which has been drained from the finished product, can be further diluted with water and subsequently used for irrigation.
Fill rotted manure (preferably cow) with water (1:3). Let it brew (3 days). Dilute with water twice and spray the bushes.
Pour 25 g of chopped garlic into 1 liter of water. A day later, when the product has infused, strain and spray the plants.

Danger to plants

Why it is necessary to get rid of mold and not allow it to spread:

The plant begins to get sick, as mold prevents nutrients from reaching the stems, leaves and flowers.
The root system does not receive enough oxygen.
Fungus in the soil can cause various flower diseases.
Due to increased humidity, the roots of the plant may begin to rot.

If you do not fight the mold fungus, the plant will rot and die.

Tips for preventing soil contamination by fungus

Fungus-infected soil is a rather serious problem, which is much easier to prevent than to solve.

Soil for plants

There are several recommendations on what to do to prevent the soil from becoming moldy:

purchase soil for indoor plants only at specialized retail outlets;
regardless of whether the soil was purchased, collected in the garden or in the forest, it is advisable to treat it before planting the plants (you can calcinate the substrate or use a solution of potassium permanganate);
used pots must be disinfected before filling with soil and replanting;
be sure to make a drainage layer;
Regularly loosen the soil in the pot to ensure access to oxygen.

From time to time, you need to add a little crushed charcoal or activated carbon to the soil.
