Why do lemon leaves turn yellow?

SHARE WITH FRIENDS:

Many grow citrus fruits on the windowsill. Not just because of the fruit, but simply for experience or hobby, curiosity. For example, they plant orange or lemon seeds and then observe the growth of the plant.

Let's find out why lemon leaves turn yellow. What to do? "We'll find out, too." There can be several reasons for this, and it is very easy to identify them by their symptoms.

Wrong light
Lemons like a lot of light, but this light should be diffused. Direct sunlight can cause burns on the leaves. Lack of light is manifested by paleness and yellowing.

SYMBOLS
Over time, small yellow spots appear on the growing leaves.

What to do.
Provide proper lighting in the room. If the pan is facing a south or west window, it must be a paper shade or a light cloth. The north and east sides of the windows are very dark for lemons. You need to install a reflective screen made of foil or glass to allow the sun to reach the target.

Owners of special phytolamps may not be bothered with such a design. They can grow lemons anywhere in the room all year round.

Draft and temperature changes
Lemons, like other plants, are very afraid of temperature differences. Sometimes the leaves do not have time to change pigmentation and fly around green. However, jaundice often occurs.

Symbols The leaves turn yellow at the edges. Then a brown border appears and a strong leaf fall begins.

What to do. If the process has already begun, then there is no point in doing anything. Do not stick the leaves behind. You need to think about prevention in the future. It is strictly forbidden to grow lemons at home:

Replacing the plant under an open window.
Sudden change in temperature of the contents.
Place the cabinet closer to the radiators.
Quickly change the air in the room.
Leave the window open at night.
As you can see, the lemon is very moody in terms of accommodation. Even re-installation from one window to another is already a change in temperature and stress. Try not to do such manipulations.

Tip. If you need to change the condition of the lemon, then do it slowly. And it is better to abandon such an initiative altogether.

Improper irrigation
Lemon is very hygroscopic. But at the same time, like most houses, it does not tolerate swamping. If such a mistake is made, the leaves immediately show their dissatisfaction.

Symptoms The leaves begin to turn yellow along the plant and along the petiole. Then comes a huge leaf fall, and then a lemon.

What to do.
Stop turning the soil in the pot into a swamp. Lemons love water, but they don't eat enough to swim in it. Irrigate properly. To do this, you need to follow a few simple conditions:

Drain filling should be at least one-third of the container volume.
Holes in the container should be monitored so that they do not become clogged with roots or soil.
Drying of soil fragments is strictly prohibited.
You can't spill a lot of liquid at the same time, it's better to pour a little, but often.
Do not use cold water for irrigation.
All this is a precautionary measure, but what if the lemon leaves turn yellow as a result of swamping? Save the plant immediately. The decay process in the root system may have already begun. Lemons should be transplanted into fresh soil and another container. This is a must.

It is important to carefully study the roots of the plant before transplanting. Visible rot or indistinguishable color, with an unpleasant odor, should be carefully cut into healthy tissue with a sharp knife or paring knife. Sections are treated with a weak solution of potassium permanganate, ordinary medical bright green or crushed charcoal. They are then air-dried for about 17-20 minutes. And only then do they eat lemons.

In the future, carefully monitor the soil moisture in the pot. Do not rush into one extreme, as the lemon flood and drought will also ruin it.

Tip. Do not pay attention to the top layer of the earth. It can dry out and become a swamp below. Don't be lazy to pick a little soil to see what's going on inside.

Power shortage
In some hosts, lemons grow in pots for several years without transplanting. It is natural for the earth to dry up. In this case, what is the health of the plant if it is unfit for human consumption? The problem is solved by moving to new soil. But only for the first time. What if the bowl is not a bowl but a large bowl? Transplanted lemons do not work. But the leaves are begging for food!

Symptoms Jaundice manifests itself in the form of spots between blood vessels. The veins themselves turn green. If the situation does not change, the lemon will die of fatigue.

WHAT TO DO.
Feeding citrus. Any improvised fertilizer. In general, lemons are very sensitive to all types of food. Keep in mind that ordinary liquid green manure contains only nitrogen. In nature, there are no such weeds in the house where other trace elements can be obtained.

Leave the principles of organic farming in front of the box and don’t make fun of the plant. Sometimes treat it with a complex mineral fertilizer solution. It is recommended to say "for citrus" in the package. If this is not possible, choose iron, phosphorus, potassium and available mineral water. These trace elements are essential for the full development and good growth of the lemon bush.

If you do everything right, you will not see the yellow spots on the leaves.

Tip. Do not overdose! There is a risk of complete loss of all leaves at the same time as feeding. You get up in the morning, put your foot on a leaf, and clear your brain - why?

Dry air
Where the lemon comes from, there is warm, humid air all year round. The latest trend in the Russian regions often coincides with the dry days of spring and summer. In the fall and winter, the apartments don’t get too wet either. Lemon is not very comfortable to eat in such an environment.

Symptoms First, the tips of the leaves turn yellow, then wither. In addition, the yellowing spreads throughout the leaf, fades, dries and falls off.

What to do. Next to the pot you should put a spray bottle with plain water. O'tdi - is sprayed, yeslab - is sprayed. Lost - destroyed the plant.

Remember: the humidity near the lemon zest should always be high! Spread the pallets with wet expanded clay, peat, or nearby sphagnum pieces. Place special containers with water. Cover the batteries with a damp towel or blanket. Buy a humidifier. Use the steam generator often. Make every effort, even to break the cake, but the air should be moist all year round!

Tip. Some gardeners even make a mini-plate without a top for the lemon. The room is dry, and in such a shelter - very comfortable in the humidity.

Pests
In addition to humans, many pests are highly respected lemon. At home, they rarely start. But in the summer, sometimes homeowners pick citrus to ventilate the garden. All sorts of disgusting comrades are waiting for him there.

Symptoms Small holes appear on the leaves, which enlarge and turn yellow over time. At the bottom of the plate you can see insects or shiny scales - these are also pests.

What to do. Immediately cover the soil with a dense cloth sheet, cover with foil or foil. Then use the lemon with water. Absolutely all leaves and buds are washed with a solution of laundry or potassium soap. You can add a handful of fine ash to the liquid. Just don’t rub the blades! You hurt them. Wash the bottom thoroughly, as there are many uninvited guests here.

If necessary, you can repeat the procedure after about 5-8 days. But sometimes that doesn't help. For example, soapy water is unbeatable for white tubes and scabs. Systemic insecticides should be used. Preferably for a long time. And even strong chemicals in a single chemotherapy don’t eat enough. In any case, read the manufacturer's instructions. Dosage and conditions of use are indicated on the package.

Tip. Try to sell bioinsecticides for sale. They are absolutely safe for adults, children and pets, which is very important in an apartment. Be sure to store the drug correctly, otherwise you will not expect any positive effects.

Illness
Lemon diseases are so large and varied that their description should be covered in a separate article. Owners should be warned about the abnormal shape of the leaf blades, cracks in the cortex, the release of dark brown sap, and the tips of the red brick-colored branches. All of these are signs of serious damage from fungi, bacteria and viruses. By the way, the latter is incurable.

There may be tips on the yellow leaves of your indoor lemon tree. What to do in such situations? First of all, find out why the tips of the leaves of indoor plants turn yellow.

Yellow spots on lemon leaves are one of the most common causes of sleeves. The fact is that the acidic citrus fruits come from hot countries, so it is very demanding to light regime. Although this does not mean that the tree will be comfortable under the scorching rays, it is better to provide it with bright but diffused light.

Yellowing of the leaves can occur if the plant is not exposed to sunlight, which is especially common in the cold season. This is due to the lack of the concept of seasonality in the homeland of historical culture.

If your lemon is not clear in the sun, there is no need to take any special measures: take the pot to the south window or provide the plant with extra light.
It is very important to follow the rules and watering regime for lemons at home. In particular, it is important to prevent the soil from becoming swampy, as the soil will have a denser structure, making it harder for air to enter the roots, and they will gradually disappear.

As a result, the amount of nutrients entering the plant is reduced, so the leaves first turn yellow at the edges and then fall off completely.

Adequate irrigation has a similar effect - a plant from a dry soil coma will not be able to get even the necessary nutrients, except for the necessary moisture. To make your little lemon feel comfortable, try watering it regularly and abundantly.

Optimal temperature conditions for lemons are up to +20 degrees so that they do not turn yellow and do not shed leaves. The tree is allowed to be temporarily moved to an open balcony or loggia, but it is better to place it in a room at night.

Try not to place your lemon next to the central heating radiators, especially during the autumn-winter period. Fever and extreme dryness explain why lemon leaves turn yellow.

This problem is consistent with that described in the previous paragraph. Excessive dryness of the air causes the leaves to gradually turn yellow, dry out and then disintegrate.

The appearance of high humidity is slightly different, but not harmful to the tree - it can lead to the development of fungal diseases. The optimum humidity level for homemade dried lemons is 80%. To achieve this, the trees need to be watered regularly.

Try to follow optimal conditions for the care of citrus fruits, avoiding disturbances in humidity levels.
Another answer to the question of why the leaves of homemade lemons turn yellow and fall off is related to non-adherence to the diet of the culture. If you have yellow spots on your tree, it is a clear sign of nitrogen deficiency, and yellowing or drying of the leaves indicates that the plant is in dire need of phosphorus.

In addition to the phosphorus and nitrogen mentioned above, elements such as magnesium, iron, zinc, potassium, calcium, and sulfur are important for the normal development or growth of homemade lemons.

Thus, a lack of zinc or magnesium can lead to yellowing of the leaves, without sufficient calcium, the root system will not develop, the plant will not be able to fully absorb nutrients, and potassium, which is responsible for better nitrogen absorption, is also important for lemons.

In specialty stores you can easily find complex fertilizers for homemade lemons, which will not only prevent yellowing and leaf fall, but also significantly improve the quality and size of future fruits.

The lemon tree in the house is attacked by other pests that disrupt the home environment, but large insects, spider mites, and swans are particularly active. To combat them, special drugs are used - Actellik (from spider mites), Fitoverm (from scales).

Finally, let's talk about the most unpleasant cause of changes in the pigmentation of the leaves of the lemon tree - a disease.
Lemons are often susceptible to fungal infections due to moisture disorders - such as scabies, late blight or warts. To prevent such discomfort, you should carefully monitor the humidity level, if you detect small signs of the initial disease, ruthlessly remove the damaged leaves and sharply reduce watering, stop spraying completely.

You need to take urgent measures to save your favorite plant from impending death. When identifying the first signs of a problem, you should carefully analyze the condition of the tree and bring them into line with the standards outlined in this article.

If everything is done correctly, the pathological process in indoor plants will stop and the tree will begin to grow with new vigor, which will delight you and your guests with a healthy appearance.
