Why leaves turn yellow in lemons. What to do?

Many grow citrus fruits on the windowsill. And not so much because of the fruits, but simply for the sake of experiment or amateur interest. For example, plant an orange or lemon seed, then observe the development of the plant.

Sometimes, one day is not a beautiful day, their pet starts to signal that he is not comfortable. And let's see why the leaves turn yellow in a lemon. What to do? - also learn. There may be several reasons for this, and it is fairly easy to identify them by signs.

Wrong lighting

Lemon likes a lot of light, but scattered. Direct sunlight causes burns on the leaves. A lack of lighting is manifested by pallor and yellowing.

Signs. Small yellow dots appear on the leaflets, which eventually grow.

What to do. Provide the plant with proper lighting.If the pot is on the south or west window, then by all means there should be a shading with paper or light cloth. North and east windows are too dark for lemon. It is necessary to install a reflective screen of foil or a mirror so that the sun reaches the shoots.

Owners of special fitolamps may not bother with similar designs. They can grow lemon in any part of the room all year round. After all, they have dosvetka.

Council If you missed and the lemon still "burned", then shading will help the plant to recover. The leaves do not break, they will serve.

Draft and temperature change

Lemon, like no other plant is very afraid of temperature changes. Sometimes the leaves do not even have time to change the pigmentation, and fly green. But most often yellowing happens.

Signs. The leaves turn yellow around the edges, curled. Then a brown border appears and the strongest leaf fall begins.

• Substitute the plant under the open window.
• Sharply change the temperature of the content.
• Position the pot near the radiators.
• Ventilate the room drafted.
• Leave the window open at night.

As you can see, lemon is rather capricious in terms of placement. Even just rearranging from one window to another is already a change of temperature and stress. Try not to do such manipulations.

Council If you need to change the conditions of the content of lemon, then do it gradually. And it is better to leave such a venture.

Wrong watering

Lemon is very moisture-loving. But at the same time, like most houseplants, it does not tolerate over-wetting of the soil. If such a mistake is made, the leaves will immediately show you their displeasure.

Signs. The leaves begin to turn yellow throughout the plant, and from the petiole. Then comes the grand leaf fall, then the lemon dies.

What to do. Stop turning the potted soil into a swamp. Lemon likes some water, but not enough to swim in it. Water it properly. To do this, follow a few simple conditions:

1. Drainage should be at least one third of the volume of the pot.
2. For the holes in the pot you need to ensure that they are not clogged with roots or soil.
3. It is strictly forbidden to overdry earthen room.
4. You can not pour into the pot at once a lot of liquid at the same time, it is better to pour a little bit, but often.
5. Do not use for watering cold water.

This is all about preventive measures, and what to do if the lemon leaves turn yellow as a result of waterlogging? Immediately save the plant. It is possible that the rotten process has already begun in the root system. We'll have to transplant lemon in a new soil and another pot. It is necessary.

It is very important to carefully examine the roots of the plant before transplanting. Visible rotten or uncharacteristic color, with an unpleasant smell, you need to carefully cut off with a sharp blade or knife to a healthy tissue. Sections are treated with a weak solution of potassium permanganate, the usual medical brilliant green or crushed charcoal. Then they are dried in air for about 17-20 minutes. And only then they plant lemon.

In the future, closely monitor the soil moisture in the pot. Do not rush from one extreme to another, for a lemon both overflow and drought are equally pernicious.

CouncilDo not focus on the top layer of the earth. It can dry, and below will be a swamp. Do not be lazy to slightly pick the ground to see what is happening inside.

Lack of power

Some owners grow lemons in pots for several years without transplanting. Naturally, the earth is being depleted. What kind of plant health are we talking about in this case, if it has nothing to eat? The problem is solved by transfer to a new ground. But only for the first time. But what if the container is not a pot, but a huge tub? Transplant lemon is no longer possible. But the leaves are asking for food!

Signs. Yellowness appears as spots between the veins. The veins themselves remain green. If the situation does not change, then the lemon will die from exhaustion.

What to do. Feed citrus. Any available fertilizer. In general, lemon is very responsive to all types of food. Just do not forget that the usual liquid green fertilizer contains only nitrogen. In nature, there are no such herbs from which other trace elements can be extracted at home.

Leave your principles of organic farming outside the door and do not mock the plant.Sometimes treat him with a solution of complex mineral fertilizer. It is desirable that the packaging was written "for citrus." If this is not available, then choose the mineral water that contains iron, phosphorus, potassium and boron. These trace elements are vital for the lemon bush for full development and good growth.

If you are doing everything right, then you will not see the yellow spots on the leaves.

Council Do not increase the dosage of fertilizers! Perekormka fraught with complete extinction of all the leaves at the same time. In the morning, stand up, turn your feet on the leaf fall, and you will wrestle with your head - why?

Dry air

Where the lemon is from, warm moist air is available all year round. The latest trend in the Russian regions often suits the dry spring and summer. In the autumn and winter in the apartments is also not particularly wet. Lemon in such an atmosphere is not very comfortable.

Signs. First, the tips of the leaves turn yellow, then they dry up. Further, the yellowness spreads over the entire leaf plate, it turns pale, dries and falls off.

What to do. You will have to put an ordinary water spray bottle next to the pot. Passed by - sprayed, remembered - sprayed.Lost - destroyed the plant.

Remember: the humidity around the lemon bush should be high all the time! Lay the pallets with wet claydite, peat or pieces of sphagnum nearby. Put special containers with water. Cover the batteries with a wet towel or blanket. Buy a humidifier. Use the steam generator often. Make any movements, even break into a cake, but the air should be humid all year round!

Council Some flower growers even arrange a minipod without a top for lemon. The room will be dry, and inside such a shelter - very comfortable in humidity.

Pests

Besides humans, lemon is highly respected by many pests. At home, they rarely start up. But in the summer, sometimes the owners pull out citrus for airing into the garden. That's where all the nasty comrades are waiting for him.

Signs. Leaves appear small holes, which over time increase in size and turn yellow. On the underside of the plate you can see insects or shiny scales - these are also pests.

What to do. Urgently close the soil with dense oilcloth, cling film or foil. Then drag the lemon to the water treatment.Absolutely all the leaves and shoots are washed with a solution of household or potassium soap. You can add a handful of fine ash to the liquid. Just do not rub the pots! You damage them. It is better to thoroughly wash the underside, this is where the majority of uninvited guests are located.

If necessary, you can repeat the procedure after about 5-8 days. But sometimes it does not help. For example, the whitefly or shchitovku soap does not overcome. System insecticides will have to be used. It is desirable with a prolonged period of validity. And even strong chemicals are not enough in the case of a single treatment. In any case, read the manufacturer's instructions. The package shows the dosage and terms of use.

Council Try to find bioinsecticides on offer. They are completely safe for adults, children and pets, which is very important in the conditions of the apartment. Just be sure to properly store the drug, otherwise no positive action will not wait.

Diseases

Lemon diseases are so extensive and diverse in their characteristics that their description should be highlighted in a separate article.Owners should be alerted by the unnatural shape of the leaf plates, cracks in the bark, the discharge of dark brown juice and the ends of the branches of a red-brick shade. All these are signs of serious damage by fungi, bacteria and viruses. By the way, the latter are not treated.

To avoid such troubles, carefully examine the lemon before buying. Most signs are visible to the naked eye. And do not believe the sellers who claim that "lemon just a little hot." It is hot fraught with the defeat of all your home plants.
