Why does the soil in the pot become covered with a white coating? Problems of growing crops Green mold on the soil.

It is worth noting that a lot depends on what kind of soil is in the garden bed and what substrate is used for its formation, and not only appearance, but also how healthy the plants are and the quantity and quality of the harvest. With the slightest changes, both in the composition of the soil and in the parameters of temperature or humidity, a number of problems may arise with the soil in a polycarbonate greenhouse or greenhouse. Among the most common problems is mold, which appears as a white coating.

The reasons why the soil in a greenhouse becomes covered with plaque may be different, but before you start certain actions, you need to decide what led to such consequences.

As a rule, this happens:

Too much humidity;
Increased acidity;
Poor ventilation in the greenhouse;
Oversaturation of the soil with fertilizer.

If the ground turns green and does not turn white, or moss and algae begin to appear, then this is the first sign of an excess of moisture. In this case, you need to pay attention to the level of illumination and the presence of ventilation.

It is important to remember that moss develops in the dark, and algae develops in too light an atmosphere.

Acidic soil is excellent and favorable environment for the formation of moss, as a result of which the ground is covered with a green coating. Moss is a plant that consumes carbon dioxide, mineral salts and water from the soil, completely depriving the plants of power.

If there is a combination of excess moisture and increased acidity, then the moss will spread at an incredible speed, and therefore you need to rush to do the treatment in order to get rid of such a problem as soon as possible. At first glance, moss seems completely harmless, but it deprives crops of all nutrients, and the consequence will be their death, the occurrence of diseases and poor-quality harvests. Moss can spread throughout the greenhouse if you overfeed the soil phosphorus fertilizer. Also, a green coating occurs due to blocking the access of oxygen to plants. Any crop needs fresh and constant ventilation. This is what makes it possible to eliminate bacteria that form on the soil and infect plants.

What to do when the soil in the greenhouse turns green

Initially, in order to remove green deposits, you need not only to treat the surface of the earth, but also to carry out the so-called cleaning. If the cause of the green deposit is groundwater and round-the-clock watering, then it must be stopped until the soil dries out.

It is imperative to establish ventilation.

If the soil in the greenhouse begins to become covered with moss, then you need to remove it using sun rays. If algae has formed, then you need to, on the contrary, block any access to light, which is done by sprinkling with sawdust or sand. More effective way The fight against greenery on the ground involves removing the top layer of soil.

Ventilation in a greenhouse and greenhouse is the most important stage when growing crops, which will eliminate not only the covering of the ground with a green coating in the form of moss, but also the formation of pathogenic bacteria.

If the soil is too acidic, then you need to:

Spread a classic deoxidizer, such as ash, dolomite flour or lime;
Sow green manure, the type does not matter at all;
A month after the green manure germinates, you can safely plant seedlings of crops such as tomatoes, cucumbers, eggplants or peppers;
After the seedlings begin to grow stronger, cut off the green manure, which can be used in the future for mulching.

Gardening experts categorically do not recommend using copper sulfate to combat moss or algae, as this radical method will remove not only pests, but also some crops, including those inhabitants of the soil that benefit plants. As soon as the soil is saturated with fine vitriol, you can safely remove the soil and throw it away. This is a tough method that allows you to overcome greenery in greenhouse soil, but it is better to push these options to the farthest drawer, otherwise you may lose the harvest for several years to come.

Mold has appeared on the ground in the greenhouse: what to do?

It is not always possible to get the desired result as quickly, simply and without special effort, since many problems often arise, in particular such as mold. Why do you need a polycarbonate greenhouse?

To grow crops:

Qualitative;
Big;
Delicious.

In order to overcome such formation, you can use special means, purchased in stores. They contain a sorbent, which increases the amount of alkali in the soil, thereby deactivating mold.

For its formation and spread, mold chooses a neutral and acidic environment.

Experienced gardeners prefer to use charcoal and ash in a ratio of 1:2. You need to wake up with this composition land plot, and loosen it. Thanks to the large number minerals and calcium, the fungus is destroyed.

Causes of mold in a polycarbonate greenhouse

By taking timely preventative measures, the formation of mold can be completely eliminated. When transplanting seedlings into pots, you need to treat them with a weak solution of potassium permanganate. If the seedlings gradually begin to become moldy, then you need to additional processing potassium permanganate and fungicides before transplanting into open ground.

Mold will appear on the surface of the soil in a greenhouse, even with proper care of the plants, if:

It will be too much heat and rare ventilation;
Too much high humidity air and soil;
There is a lack of lighting, natural rather than artificial;
Too poor ventilation in the greenhouse and greenhouse;
There are problems with sealing in the irrigation system, and hoses are leaking, because these are the places that are most suitable for the formation and development of fungus.

The reasons for the appearance of mold have been described previously and, accordingly, in order to avoid such consequences, you simply need to prevent them. In particular, regularly ventilate the greenhouse, especially if the weather is hot and completely windless. This needs to be done daily. In addition, you need to ensure that perspiration does not appear on the walls of the room, and if such wet areas form, they are removed with a dry cloth.

It is these parts that will become the source of fungus.

Watering the plants is carried out so that there are no stagnant puddles on the surface of the ground. In order to maintain optimal humidity, it is advisable to install containers with water on the floor, which will ensure that the plants take in the water and air that they require, and an optimal microclimate will be maintained without sudden changes.

Gardener's answer: why does the soil in the greenhouse turn green (video)

Experienced gardeners prefer to install greenhouses that have vents on the roof. By opening them, the soil is dried and ventilated, which eliminates all the problems described above and reduces the likelihood of plant death several times.

This problem is probably familiar to many who are interested in house plants. Sometimes it happens that upper layer in pots with your favorite flowers slowly begins to turn white. It doesn't look like mold. Then why is the earth covered with such a coating, and what is it missing?

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

I think many people understand that most of these problems in home floriculture usually reflect our mistakes in caring for plants. This “white veil” is an ordinary crust of salt. She may be white, and sometimes white-yellowish. Such a crust occurs in pots simply when the physical evaporation of water from the soil significantly prevails over the evaporation of the same water from the plant itself. Again, as always, there are several reasons for this:

Perhaps the mechanical composition of the mixture that is in the flower pot is too heavy. This is why high (sometimes even excessive) capillarity occurs and because of such capillarity, water is more intensely drawn to the soil surface.

Again, mistakes cannot be ruled out when watering the plant. Perhaps you water immediately with water that was just poured from your tap. There is no need to do this, let it settle at least a little.

Drainage at the bottom of the pot may be difficult. If this is so, then again evaporation from the very surface of the soil in the pot will be the main way of consuming moisture.

Perhaps you simply over-fertilized the mixture or you already purchased such a mixture. After all, many manufacturers of such soil mixtures This is exactly what they are guilty of, especially if they make this mixture for vegetables.

We went too far with fertilizing.

And a simple reason that immediately comes to mind for many is the banal dryness of the air itself. It is because of the dryness that evaporation increases many times over and the salts are “pulled” to the surface.

In addition to all these points, white plaque can easily appear due to fungal microflora. Such microflora is again created by our efforts, which we show excessively when watering. Therefore, to get rid of such plaque, water your flowers correctly (read about it). That is, when the top layer of soil in the pot has already dried out.

What to do and how to get rid of it?

To reduce such white (and any other) deposits, you just need to cover the soil on top with expanded clay. Of course, such a coating may appear on expanded clay after some time. Then they simply remove it, wash it thoroughly and put it back in place.

Another option is to sprinkle soil in the pot. river sand. After this, the top layer along with the sand should be loosened. The very addition of sand and subsequent loosening of the soil is very beneficial for the roots of your plant. Also, you can remove the top layer itself and simply add good leaf soil or equally good humus in its place.

The easiest way is to remove all this “whiteness” along with the soil, and then add new soil.

If the water in your home is hard (and most of the time it is), then you should use filters. You can also soften the water for irrigation. To do this, simply put a rag bag into the jar, where you need to put a little peat.

One of the options for the appearance of such a plaque is dry air, which is not uncommon in our apartments in winter. Because of this, we begin to water the plants more often, and for this reason the soil becomes covered with such a coating. (How is everything interconnected!?) To avoid such mistakes, watch this video.

Many summer residents wonder why the soil in the greenhouse turns white, because they take such careful care of it, fertilize it, water it and weed it. So what is the cause of green soil, mold and white residue?

The most common causes are excessive soil moisture, pests and improper care.

The soil is sick for several reasons:

If you water the soil endlessly.
With increased soil acidity.
When the greenhouse is poorly ventilated or absent at all, resulting in increased humidity in the room.
If you add a lot of fertilizers to the soil.

These reasons can be combined with each other.

Pests, insects and diseases

Very often, pests lay their larvae in the soil where they are for a long time. If this problem is not dealt with, the number of harmful larvae in the soil will only increase. And some conditions can contribute to this, for example, heating the soil in the cold season, etc.

The most common pests include:

wireworms,
cabbage flies,
mole cricket,
spider mite and others.

Other types of soil diseases include infections vegetable crops are various mold spores and fungal diseases, which can also penetrate the soil and cause contamination. Many microorganisms are able to penetrate not only into the soil, but also constantly remain on the frame of the greenhouse itself (especially if it is made of wood). Therefore, if you carry out measures to disinfect the soil, it is necessary to touch all parts of the greenhouse in order to completely prevent the re-production of harmful microorganisms.

Common soil diseases:

clubroot;
late blight;
spots on leaves;
macrosporiosis;
peronosporosis.

Soil waterlogging

If the soil is waterlogged, then in the near future you may find algae, fungus and mosses in your beds. This is also facilitated warm air in the greenhouse. There may be special deceit on the part of groundwater, which may be located in the greenhouse area. Often, the owner of a greenhouse may not be aware of this and water his plants as usual; as a result, excessive moisture occurs, which in turn leads to soreness and greening of the soil.

How to distinguish moss from algae? These two species can often be confused, but they have distinctive features:

When the greenhouse lighting is poor, moss appears on the plants and soil.
But if there is enough light in the greenhouse, then we can talk about the formation of algae.

Causes of white plaque and measures to get rid of it

White coating is a yellowish crust consisting of salt. It can form for the following reasons:

If the soil composition is considered mechanically heavy.
Difficult soil drainage.
With poor or scanty watering.
Too much fertilizer in the soil.
A large amount of fertilizing in the soil.
The composition of irrigation water may contain large amounts of chlorine, calcium or magnesium.
Dry air.
Fungus or mold.

Ways to combat plaque.

The appearance of green and white deposits in the soil is associated with excessive waterlogging of the soil.

You can get rid of white deposits on the soil in different ways:

For example, you can sprinkle the surface of the soil with expanded clay. It is on it that a white dried sediment will appear; from time to time the expanded clay needs to be washed and returned to its place again.
Sprinkle the top layer of soil with river sand and loosen it more often. This is very beneficial for the root system of plants.
You can remove the top layer of soil and add leaf humus.
Remove the top layer of soil and fill in a new one.
Purchase a soil deoxidizer from a specialty store. Remove the top layer of soil and pour the deoxidizer deeper.
Water the soil with softened water. To do this, use a special filter. You can put a bag of peat in a bucket of water. If possible, water should be passed through a layer of peat, then the salts will be adsorbed.

Increased soil acidity

To reduce the acidity of the soil, which causes moss and mold to spread throughout the area (and this is detrimental to plants), you need to take the following actions:

Add tree resin to the soil; this should be done from time to time. But not too often.
Add lime to the soil.
Dolomite flour added to the soil effectively eliminates soil diseases.

It is advisable to add these fertilizers to the soil at the time of digging up the earth, before planting and after harvesting. In this case, the soil in the greenhouse will not deoxidize, causing mosses to stop appearing.

To ensure that plants grow well in the soil and produce a harvest, do the following:

Sprinkle lime on the soil and do not dig up the soil.
After this, sow green manure - this is a fast-growing grass.
After the grass sprouts, plant seedlings of other vegetable crops in the soil.
After the seedlings have taken root, the grass is mowed and subsequently used as mulching material.

Getting rid of mold in a timely manner will protect you from possible health problems. Gardeners and gardeners are often faced with the problem of mold on the ground in a greenhouse. This is a type of fungus that is harmful to both humans and plants. It contains allergens, carcinogens and other toxic substances. Therefore, fruits grown in greenhouses with contaminated soil are not recommended for consumption, especially for children.

To prevent mold on the ground in a greenhouse from becoming a pressing problem, it is necessary to take a set of measures to prevent its occurrence.

This fungus appears regardless of the type of greenhouse and soil composition, and grows very quickly. Mold can be white, gray, or even pink. The most common is green mold. It's the hardest thing to get rid of.

Preventive measures

ABOUT preventive measures It's worth taking care of in advance. For example, before planting seedlings in pots, it would be a good idea to treat them with a weak solution of potassium permanganate and prevent mold from occurring during the period of its growth. If, nevertheless, the seedlings are covered with mold, then you need to treat the soil with a weak solution of potassium permanganate or fungicides (phytosporin-M or foundationol) before transplanting it into the greenhouse.

The main causes of mold are the following factors: high humidity in a greenhouse, lack of direct sunlight, poor air ventilation.

In order to avoid the appearance of mold in a greenhouse, it is necessary to ventilate or artificially ventilate it daily.

Accordingly, in order to avoid its appearance in the greenhouse, it is necessary to regularly ventilate it or ventilate it artificially. This should preferably be done daily. Moreover, when large quantity perspiration on the walls of the greenhouse, wet areas must be wiped dry and try to avoid excessive humidity. Plants should be watered in such a way that the water on the ground and on the floor of the greenhouse does not stagnate in puddles. To maintain optimal humidity, it is better to place containers filled with water on the ground or floor. If possible, you need to open part of the greenhouse at least 2 times a week to allow sunlight to penetrate inside.

Ways to combat emerging mold

If mold appears on the ground in a greenhouse, the soil can be treated with a special purchased product, which most often includes sorbent substances that increase the level of alkali in the soil, which makes the mold unviable. A neutral or acidic environment is favorable for its reproduction.

Charcoal and ash, which have a high mineral content, are the best way destruction of mold and fungal spores.

The most common use is charcoal with ash in a ratio of 1:2 (or ash separately), which is sprinkled on the ground and loosens it. The mineral content, in particular calcium, destroys fungal spores.

Another means of combating mold is peat, treated with copper sulfate and lime. To prepare the product, pour 1 liter of 0.1% solution copper sulfate for 4-5 hours until swelling. Then knead until a homogeneous mass is obtained, add 15-20 g of limestone flour and mix again. There should be no lumps in the resulting mass. This mixture is used to mulch the soil. If after 2-3 weeks the mold appears again, this procedure can be repeated.

What is important when growing indoor plants? Certainly, good soil, because it is he who gives our flowers nutrients, thanks to which they actively grow and delight with their flowering. Poor quality soil not only inhibits growth, but can also cause the death of indoor crops, so all flower growers carefully select a suitable substrate for their pets. However, it often happens that a good, nutritious soil mixture is covered with a white blanket.

Reasons why the earth is in flower pots covered with a white coating, maybe several, namely:

Poor quality water is used for irrigation;
A fungal infection has settled in the flowerpot.

Water problems

Regardless of the type of indoor plants for all flowers there is general rule: for irrigation, you should use only settled water, or even better, rainwater. Tap water goes through cleaning systems and is “enriched” with some elements that flowers do not like, for example, chlorine. In addition, it is too hard, so after watering, lime deposits appear on the surface of the ground. Externally, such soil looks like dry white granules; if you carefully remove them, you can see ordinary black soil underneath. This is usually what they do, removing the top layer and pouring fresh soil mixture into the pot.

To prevent the appearance of sediment, water the flowers only with settled water. You can soften it using homemade filter, putting a little in a rag bag and lowering it into a container of water. also in flower shops Special softeners are sold.

To neutralize lime compounds, it is recommended to add lemon juice or kitchen acid (citric acid) to the water.

Fungus in the soil

If white coating the pot is damp and resembles fluff, and an unpleasant putrid smell emanates from the soil, which means a fungus has settled there. We often create a suitable microclimate for the occurrence and progression of mold and rot ourselves by intensively flooding the plant. And as you know, constantly moist soil is an ideal environment for many diseases.

IN in this case It’s better to take the most radical measures and completely replace it with a fresh one. Treatment with fungicides to destroy and prevent fungal infections will also not hurt. From now on, when watering, you should follow the golden mean and be sure to monitor the moisture content of the substrate.
