By keeping indoor plants and flowers in the wrong conditions, you risk your green pets. With improper care and cultivation, they weaken and begin to hurt, becoming more vulnerable to parasites and pests.
Factors causing the disease state of plants
Of the reasons associated with plant inhibition, a deficiency or oversaturation of a green pet with moisture, light, heat, nutrients, and acidity of the substrate is distinguished. There are a number of other causes of indoor flower diseases . Explore the main causes and subsequently emerging diseases of indoor plants.
Diseases of plants caused by improper care
Parasites and infections are not the only foci of disease in domestic plants. There are a number of diseases of living plants that can be caused by improper care of them.
Top dressing
Due to the lack of certain vitamins, macro- or microelements in the soil, plants suffer from non-parasitic diseases. The deterioration of the state of the plant, caused in this way, is not transmitted from one representative to another and is easily eliminated by providing the necessary growing conditions.
Air humidity
Due to the unfavorable microclimate, deterioration and some diseases of indoor plants occur. So, for most representatives of home flora with low humidity:
- the leaves dry and fall;
- the tips and edges of leaves, buds and flowers darken and dry;
- testing of stems and leaf plates occurs.
Watering
Improper watering can also trigger a number of diseases. Excess moisture leads to acidification of the substrate, as a result of which the normal vital activity of the plant is disturbed. As a result, difficulty in breathing the root system, leading to decay and poor absorption of substances. At the same time, a healthy plant acquires an unusual color, the leaves become stained, and the stems at the base begin to decay. Look at the photo of a houseplant disease. How to deal with such a problem? Keep an eye on the flower watering system.
Lighting system
Improper lighting often contributes to the painful manifestations of indoor plants. Thus, a lack of light can contribute to the formation of an irregular crown. If the leaves begin to lighten and as a result fall off, then the flower does not receive enough light. If it was normally impossible to organize light of natural origin in principle, make up for the need of the plant in the form of an artificial source.
Remember that excess sunlight is just as dangerous as its lack. Burns may appear on the leaves, leaf plates become covered with dry spots, the tips dry out. The right lighting system is one of the tips on how to deal with indoor plant diseases.
Temperature mode
The temperature for each representative of the flora is an important factor, especially for those plants that are grown by flower growers on the windowsill.
At low temperatures, the leaves fall and die, sometimes the flower dies completely. Those plants that suffer from high temperatures begin to fade and also drop leaves.
Painful manifestations in plants and the causes of their occurrence
In the table below, read why plants suffer from non-parasitic diseases and what can lead to diseases in indoor plants.
Causes of plant diseases and their external manifestationsPainful manifestation | The reason the plant has weakened |
Old leaves turn yellow | Macronutrients and nitrogen are inadequate. Lack of light in the spring and winter. Excessive heat, especially at night. |
The tips of the leaves turn yellow | Excess calcium in the substrate. Dry soil. |
Leaves turn yellow-brown | Irrigation water contains excessive amounts of calcium and chlorine. |
The plant is completely yellowed | Waterlogging of the soil. Chronic lack of moisture. Heavy substrate. Dense earthen lump. Reduced humidity. |
Sagging leaves, loss of turgor, shedding of healthy foliage | Watering with cold water. Water contains salts in high concentration. Violation of the temperature regime of the plant. Keep in a cold place; Lack of copper. |
Foliage curls, wrinkles, inter-vein chlorosis | Hypothermia. |
Premature Leaf Aging | Lack of potassium, magnesium, zinc. |
Deformation of leaf plates, twisting along the veins | Infestation with a cow, aphids, and thrips. |
Light spots on the leaves | Sunburn. Traces of drops of water. Reaction to a cold environment. |
The formation of brown, oily, gray-white spots on the foliage | Leaf nematodes. Fungal or bacterial diseases. |
Dark green leaf spot | Oversaturation with nitrogen. Lack of lighting. |
Line mosaic or mottling | The defeat of viruses. |
Whitish, pale green, yellow foliage with green veins | Lack of Cu, Fe, S. |
Partially dry brown spots and vitreous discharge on leaves | Increased humidity. The problem is a waterlogged substrate. Stagnant air. Low room temperature. The development of fungal diseases. |
Small injections or specks on the leaves | Pest damage: ticks, thrips, aphids. |
Edged edges and holes in the leaves | Defeat by bugs, slugs, caterpillars. The development of fungal diseases. |
Lack of bud formation or small planting | Inadequate plant conditions during dormancy. Unfavorable ratio of lighting and temperature. Oversaturation with nitrogen. Insufficient humidity in the room. Diseases and pests of indoor plants. |
Sudden fall of foliage | A sharp jump in temperature. The drying up of an earthen coma. Fungal diseases. Bacterial wilt. |
Shedding buds | It can be triggered by sharp temperature fluctuations, for example, during ventilation. Reduced humidity. Drying the soil in a pot. Not enough light. Unbalanced top dressing. Oversaturation with nitrogen. |
Yellowing and falling of leaves | Irregular and not systematic watering. Drafts. Excessively high temperature in low light conditions. |
Withering flowers | Drying the substrate. General starvation of the plant. Oversaturation with nitrogen. |
The formation of short peduncles | Incorrect feeding of plants. Unsuitable substrate. General starvation of the flower. Irregular watering. Temperature fluctuations. Violation of the norms of detention during rest. Excessive heat during bud formation and growth. |
Leaves are covered with powdery white coating. | Powdery Mildew Peronosporosis. |
Bacteriosis in plants
Bacteriosis is a disease of indoor plants caused by bacterial forms. Today it is rare in indoor plants, but it is better to know in advance about the symptoms of invasion and methods for eliminating the disease.
Remember that bacteriosis affects not only garden and garden crops, but also flower indoor plants. Onions most often suffer from this disease and, if they are sick, they receive huge damage from infection. It is interesting that when this disease is damaged in cultures of different species, the symptoms manifest the same way, and the disease itself proceeds with the plant withering or spotting and rot appearing on the leaves. Sometimes blackening of leaf veins is observed. So the disease of leaves of a houseplant is manifested.
A typical sign of the disease is the wilting of the plant and the appearance on the leaves of rot and spotting, blackening of the veins of the leaves.
Most often, plants that are contained in moist, warm rooms suffer from bacterial spotting.
Gummosis
Often get sick citrus. The bark of the trunks is covered with brown-red spots of a longitudinal shape. With the development of the disease in places of damage, the cortex dies, and a sticky yellowish liquid, gum, which dries in the air, begins to ooze from under the cracks.
Sometimes the course of the disease occurs without leakage of fluid. So, in places of damage the bark becomes dry, but it does not peel off. As a result, deep cracks form in this disease of indoor plants. The photo illustrates how the disease looks.
Under the influence of gummosis, the plant begins to change the color of the leaves foamy from greenish to yellowish, and then lose them. Fruit formation is observed, but they are very small.
Chlorosis in home indoor plants
With a deficiency in the substrate of such elements as zinc, manganese, iron, plants begin to suffer from leaf chlorosis. Sometimes a violation of the absorption process of these elements, in most of the soils with excessive liming, can cause the development of the disease. In the photo, the disease of leaves of indoor plants caused by a lack of minerals.
As a result of the disease, the undersides of the leaf plates become yellow and die as a result. With chlorosis, a slow development of plant organs such as buds, leaves, stems, and root system is observed.
Root rot
Root rot is a common plant disease. The main difference between root rot and other diseases is the property of destruction of tissue cells, which inevitably leads to decay of the root system. See how this disease of indoor plants begins in the photo below.
The roots usually become brown, and after a while completely die off. After the root system has died, the disease spreads rapidly, actively killing the cells of leaves and flowers of plants. So, root rot is a disease causing the complete death of a flower.
Diseases and pests of indoor plants: methods of prevention and methods of protection
Whatever care you would provide your plant, efforts and efforts can be in vain if pests infect the indoor flower, provoking diseases.
A green plant suffers for many reasons, and not all of them can be explained. The most common cause of infection is the transfer of diseases and harmful insects from one representative of the fauna to another, for example, when buying a plant.
Another reason is the latent state of infection inside its carrier.
In favorable conditions for pests (with a warm microclimate in your room or improper care), diseases and pests develop and manifest. The first reason plants suffer is more common.
So how to treat diseases of indoor plants and contribute to the conservation of any green pets? One of the most popular among flower growers and effective methods is preventive disinfection of flowers. As many gardeners and gardeners say, prevention is much more beneficial and better than treatment. After all, it is better to prevent the problem in advance than to deal with the problems later.
Prevention methods consist in spraying plants and flowers with a weak solution of a fungicide or insecticide according to the scheme - 1 time in 20 days during the warm season.
Of the means for treating plants, 90% are chemicals that can be dangerous for the plant and its living organisms if the product is used improperly. Therefore, going to carry out preventive maintenance for green friends, choose one of the safest options.
No wonder the proverb sounds so loud: “Forewarned - armed!” Prevention is the best protection of indoor plants from diseases.
Carefully inspecting home plants at least once a week, taking preventive measures, seriously treating sick representatives, be sure that the guaranteed protection is provided to your favorite indoor plants.
