Aloe (aloe) - Succulent, which is found in almost every home. The popularity is due not only to the unpretentiousness of care, but also to the healing properties, thanks to which the plant is considered a "home doctor". Despite endurance, there are cases when a flower with its appearance signals an existing problem. It is worth considering why aloe leaves turn yellow and what needs to be done to save the plant.
Why do aloe leaves turn yellow and the tips of leaves dry
There are many reasons that cause yellowing and drying of aloe leaves. All of them are connected with violation of growing conditions. As a result, the natural immunity of the plant is reduced.
Distinguish more than 500 species of aloe
The main provoking factors:
- insufficient lighting;
- temperature mismatch;
- prolonged lack of transplantation;
- too big pot;
- drying of the roots;
- pests, diseases;
- use of cold water for irrigation;
- lack of nutrients;
- non-compliance with the irrigation regime.
Leaf problems can occur in aloe even with a slight violation of the conditions of detention. So the plant shows that he needs help. And the sooner the root cause is eliminated, the faster the succulent will recover.
How to save a flower if it dies
Most often, leaves in aloe begin to fade against the background of dysfunction of the root system. This can be caused by a cramped pot, overflow or drying out. Regardless of the main reason, it is possible to save the plant only by transplantation.
In this case, damaged roots, leaves are removed and the substrate is completely replaced. The new soil should not only be nutritious, but also contain sand, which eliminates the possibility of stagnation of moisture.
It's important to know! You can water the succulents for the first time after transplanting no earlier than a month later.
Improper aloe vera care as one of the causes of dried leaf tips
Often the reason why aloe vera turns yellow is due to a breach of care and maintenance. It is necessary to consider all possible options, since in each particular case specific signs appear by which you can determine the problem.
The lower leaves became stained at the base and fell off
Signs appear as a result of stem decay at the base, which is caused by waterlogging of the soil in combination with a low content temperature. As a result of this, metabolic processes in the tissues are disturbed. As a result, the root rots, and nutrients cease to flow to the upper part of the plant.
Lower leaves die off due to root problems
If spots appeared on the aloe, namely on the lower leaves, urgent measures should be taken to save the plant. It is necessary to stop the development of rot, which spreads up the stem. To do this, take aloe from the pot, remove the entire rotted part to a healthy tissue. Dry the slice for 1-2 hours, and then powder the lower part with Kornevin. After that, plant the plant in a soil mixture of peat and sand, taken in equal amounts.
It's important to know! During rooting, do not cover aloe with a plastic bag, like other plants, as it rots.
Watering is rarely carried out, in a pan, so that only the bottom layer of soil is moistened. The following hydration is done after the substrate has completely dried. This regimen is respected until the plant is fully restored and grows.
Leaves blush
If aloe leaves turn red and the tips dry, then this is a sign of sunburn. So the plant reacts to bright light. Most often this happens in early spring, when the daylight hours increase markedly (a partial shade plant is put on the windowsill). As a result, the leaves may turn red.
Additional Information! To accustom to the bright illumination of aloe after the winter, you need to gradually, and shade from direct sunlight.
The lower leaves turn yellow
Simultaneous yellowing of several lower leaves can occur for a number of reasons.
If a warning sign appeared in winter, then it indicates a depletion of the flower. This occurs as a result of heavy watering combined with a lack of light. The lower leaves turn yellow, and the top is extended, the plates become thinner and become less fleshy.
Understanding why aloe leaves turn yellow, you should figure out what to do. In winter, a full 12-hour daylight should be provided with lamps in the evening. If this is not possible, then you need a cool mode of about + 12 необходим and keep the plant in almost dry soil, moderately moistening once a month.
Yellowing leaves in aloe can be caused by a cramped pot
In the case of yellowing of the lower leaves in the summer there is a lack of nutrients. A common cause is a prolonged lack of transplantation or top dressing. So the plant gets rid of old leaves to ensure the growth of new ones. To remedy the situation, fertilizer is introduced for succulents, and if this does not help, then transplanted into a new substrate and increase the pot.
Note! A sharp yellowing of the lower leaves at any time of the year can provoke a temperature difference, which will lead to stress. To correct the situation, adjust the conditions of maintenance and watering. Humidify succulent more often in the hot period, and less often in the cool period.
Soft aloe leaves
Leaf loss can also be caused by various factors. In hot periods of the year, when the plant stands in direct sunlight, this is observed with excessive evaporation of moisture. In this case, the root of the plant is not able to cope with the increased load and make up for the deficiency. To correct the situation, they rearrange the plant in a shaded place.
Aloe leaves wilt can occur at a low temperature. With a constant mode below +10 ℃, irreversible processes occur in the plant tissues in combination with excessive watering, which leads to the death of the flower. Aloe can withstand a cool microclimate if it is gradually accustomed to a new temperature and limit watering.
Important! Excessive watering will not solve the situation, as it can lead to rotting of the roots.
Aloe leaves curl
The symptom may appear as a result of drying of the roots. This usually happens in the winter, when the pot with the plant is located on the windowsill near the radiators. In this case, yellow leaves are removed, and then the flower is rearranged in another place, providing it with frequent but moderate watering.
Aloe can curl leaves if it is exposed to direct sunlight. Succulents are trying to protect themselves and reduce moisture evaporation. The symptom may appear when dust accumulates on the leaves, which impedes the process of photosynthesis. It is necessary to regularly wipe the plates, and in hot periods, additionally spray the flower in the evening, so that moisture can soak into the leaves until the morning.
Aloe's twisting leaves are a sign of excessive moisture evaporation.
Aloe Disease Affecting Leaf Condition
Foliage may turn yellow due to aloe disease. Among the most common include root and dry rot. In both cases, there are characteristic signs indicating a disease.
Root rot develops as a result of excessive watering, cool keeping, and planting in an inappropriate substrate that retains moisture. If the plant begins to die, then its leaves turn completely yellow, fall off, the stem at the base becomes dark, and the flower itself bends. Aloe can be saved, like other plants, by transplanting into new soil.
Procedure:
- Take the plant out of the pot, clean it from the ground.
- Examine the roots and remove all suspicious parts.
- Process the pot with a strong solution of potassium permanganate or boiling water.
- To prepare the soil mixture from sand and peat in an equal volume.
- At the bottom of the pot lay drainage with a layer of 1-1.5 cm.
- Fill the rest of the space with the prepared substrate.
- Plant aloe in the center of the pot, compact the surface.
- Sparingly pour into the pan.
Then rearrange the pot with the plant in a shaded place until complete recovery. Watering is carried out after complete drying of the substrate and only in the pan.
Note! If root rot managed to spread to the stem and leaves, as a result of which they began to blacken, then it will not be possible to save aloe.
Dry rot manifests itself in the form of pale spots of irregular shape on the leaves of the plant. Subsequently, they grow. With a severe defeat, aloe growth slows down, and the general appearance becomes dejected. In this case, the leaves do not fall, and the plant fades. The cause of the development of gray rot is contaminated soil. To treat in this case is useless.
Aloe pests as a cause of yellowing and drying of leaves
Aloe leaves can dry out and turn yellow as a result of damage by pests. This can be determined by a thorough examination of the aerial parts of the plant.
The defeat of aloe vesicle
Possible problems:
- Spider mite. A small insect is difficult to see with the naked eye. It is possible to identify a lesion by the presence of small bright points along the edge of the leaf plate. Subsequently, a thin cobweb also appears on the leaves and stems.
- Thrips. The pest eats the juice of the plant, thereby weakening it. A lesion is detected by the presence of black dots on the leaves. In this case, the plates turn yellow and deform.
- Mealybug. The pest is a white insect. With a massive accumulation on the leaves, a cotton-like coating is noticeable. Propagated in the upper layer of soil, and then spreads to the leaves and stem of aloe.
- Shield. The pest is like small motionless plaques that can be removed with a fingernail. Initially localized along the main stem, and then switches to leaflets. Yellow spots appear in these places.
With a small accumulation of pests, you can wash the leaves of the aloe with a soap or garlic solution. For mass lesions, chemical agents are used: Actellik, Fitoverm, Fufanon. Which of them to choose, the grower decides for himself, depending on the complexity of the situation.
Additional Information! Processing of the aerial part should be carried out 2-3 times with a frequency of 5-7 days, alternating drugs. In the case of scabies, the plant is additionally watered with Aktara working solution.
What to do with root problems
The most dangerous reason that aloe begins to die is a violation of the function of the root system. As a result, not only the leaves can disappear, but also the plant itself can rot or dry.
Key signs of root problems:
- unpleasant odor near the ground;
- excessive exposure of succulents at the base;
- developmental stop;
- the trunk begins to blacken below, and leaves disappear;
- become sluggish plates.
When at least some disturbing symptoms appear, measures are taken to save the flower. To do this, they take it out of the pot and remove all damaged areas to healthy ones. Then washed from the remnants of infected soil and transplanted into another pot and new soil.
Transplanting is the only way to save dying aloe
How to reanimate a fully dried plant
Often, flower growers ask: if aloe dries, how to transplant and restore the plant? You should understand this issue.
With a long absence of watering, the root system ceases to function, and therefore, nourishes the leaves. Abundant watering in this case will only accelerate the death of succulent.
You can save the flower by rooting the top. To do this, cut it with a clean knife, dry the slice for 1-2 hours. After that, sprinkle with any rooting agent and plant in a mixture of peat and sand in a ratio of 1: 1.
Important! During the rooting period, aloe is watered 1 time in 3 weeks and through a pallet so that only the lower layer of soil is moistened.
How to care for the plant so that there are no problems
Aloe is an unpretentious plant, but when you ignore the requirements, it begins to wither. Many problems can be avoided if you follow the simple rules of care:
- Aloe needs good lighting, so it is recommended to keep it on the south or east windowsill with shading from direct sunlight.
- A pot for a plant can be used both clay and plastic, but its diameter should be 2 times smaller than the crown.
- Watering should be done as the soil dries into the pan or along the edge of the pot. To do this, use settled water at room temperature.
- Land for planting should be bought with a special mark "For succulents."
- A flower under the age of 5 years is transplanted annually in the spring, and older - 1 time in 3-4 years.
- Top dressing is carried out regularly in the warm season, using fertilizers for succulents. In the autumn-winter period they are reduced to 1 time per month and the concentration is halved.
- The leaves of the plant are periodically cleaned of dust so that the photosynthesis process proceeds normally.
- In particularly hot periods of the year, leaves are sprayed in the evening.
Aloe is a medicinal succulent that can forgive the grower for minor errors in care. With a constant violation of the rules of agricultural technology, the plant's immunity decreases, which leads to problems with leaves and roots.
