Dracaena - a popular indoor flower, quite unpretentious in the care. However, sometimes there are problems with the cultivation of this palm-like plant - its leaves turn yellow, slowly losing their attractiveness, and then fall off. The reason for this may be improper conditions of detention, agricultural errors, defeat by pests or diseases.
The main causes of yellow leaves dracaenaWhy do the leaves of the adult dracaena turn yellow at home? Often, due to their age - after a 2-year period, they begin to change color, and then die. In this case, it is enough for the florist to remove the old yellowed deciduous mass, so that the young and green ones can grow. However, if the problem was identified on a young plant, there may be several reasons for this.
Improper organization of watering
Excessive irrigation craze can cause yellowing of the deciduous mass of dracaena due to problems with the root system. Soil in the pot dies and the plant can not cope with excessive moisture, so it is extremely important to adjust the watering, not only in summer but also in winter.
Proper watering dracaena includes:
- Moistening the soil in the summer about 2-4 times a week after the upper layer of soil dries out,
- In winter - once a week and a half after the substrate has dried completely in a pot,
- Use only distilled water at room temperature, or thawed rain.
If you wash the dracaena under the shower, you can avoid sticking the soil in the pot after the water falls from the mixer by wearing a plastic bag or wrapping it in a plastic wrap.
Violation of temperature and content in dry air
Optimally contain dracaenum at a temperature regime that is in the range from +19 to +25 degrees Celsius. Despite the fact that the flower comes from the tropics, too high temperatures can adversely affect it and cause yellowing of the leaves at the tips, which dry and fall off. Being in a cold room is also extremely undesirable - the plant will begin to ache and may die.
Dracaena reacts poorly to temperature fluctuations, so putting a pot in the winter on an unheated windowsill is a bad idea. Drafts are also undesirable - they cause frosting of the hardwood part and affect the general health of the flower. If you notice that dracaena begins to suffer from hypothermia, immediately transfer it to a warm room and carry out regular spraying of the leaves. After a while, the plant will recover and return the lost beauty.
Tropical homeland dracaena affected its whimsicalness to dry air. The plant loves high humidity (65-80%), therefore its content on the window sill, where the sun constantly shines or near heating devices, ensures yellowing of the leaves and their falling off. To avoid this situation, simple measures are enough:
- Do not put dracaena near batteries
- Spray the foliage regularly with water from a spray bottle
- Periodically wash the leaves from dust (1 time per month),
- Bathe dragon flower under the shower in the hot season.
The only caveat - spraying or bathing should be done carefully, so that after the water procedures there is no liquid in the leaf axils. It can cause decay of the deciduous part with further death.
Lack of fertilizerYellowing of the tips of the leaves and their fall is a consequence of a lack of nitrogen. During active growth, dracaena needs additional feedings, therefore it is important to select a complex fertilizer, which will include the specified component.
It is necessary to apply fertilizer in the period from March to August, but in winter it is better to refuse fertilizing with nitrogen content. It is necessary to fertilize dracaenum 2 times a month with a complex composition, slightly reducing the concentration indicated on the package. If the room temperature is in the range of + 16- + 20 degrees, the number of fertilizing should be reduced to 1 time per month.
During the growth of dracaena, you can use the following composition for top dressing, which is best absorbed when spraying the hardwood part (foliar top dressing):
- 0.3 g of ammonium sulphate,
- 0.5 g of potassium nitrous,
- 0.4 g of potassium phosphate.
These components are mixed, and then dissolved in 1 liter of water.
To stimulate the growth of deciduous mass dracaena, you can use a solution of nitroammofoski prepared according to the instructions on the package. It is introduced into the soil 1 time in 2 weeks. The use of special preparations “Master”, “Stimulus”, which are also applied as a top-dressing 1 time in 14 days, will help prevent death and leaf fall.
The stores also feature long-acting fertilizers for decorative and hardwood indoor plants in the form of sticks. They are also quite effective, since the constituent components are released gradually, feeding the plant. For a pot, 1 stick is enough to be inserted vertically into the soil, then shed the ground a little.
The average frequency of dracaena transplants is 1 time in 3 years. If the plant is in the old substrate for a long time, it begins to experience nutrient deficiencies due to the accumulation of salts. They interfere with the root system to absorb the necessary micro and macro elements, thereby causing yellowing of the deciduous mass.
In order to prevent such a situation, it is recommended to transfer the dragon flower to the new pot once every 2 years, the diameter of which will be about 2-3 cm larger than the previous one. is deformed.
The soil can be prepared independently by mixing equal parts of leaf and sod land, sand, mid-peat and humus. It is also necessary:
- To prevent the development of rot add to the substrate crushed wood or activated carbon,
- To drain excess water, drain holes (if they are missing) at the bottom of the pot,
- Place a drainage layer on the bottom of the pot (1/10 of the total height of the tank) to prevent root system rotting.
Usually dracaena, tolerates low humidity, despite the fact that its homeland - the tropics.
But with very dry air, at its leaves, the tips first dry up, and then they become soft, lethargic and turn yellow throughout the entire crown. As a result, this leads to their mass drying and falling off.
We must not allow a strong decrease in humidity in the room where dracaena grows. With excessive dryness, it is advisable to put a humidifier. Dracene can be kept in a deep pan with a wet substrate. - pebbles, expanded clay or moss. Good results are obtained by spraying the plants with separated water twice a week.
Cold and draft
Dracaena reacts painfully to rapid changes in conditions of detention. It does not tolerate a sharp decrease in temperature and drafts. At the same time its leaves may turn yellow or darken, and then fall off.
For plants, you must choose a place protected from drafts. Do not place it near the opening window or balcony door.
When airing, especially in winter, it is advisable to take the dragon flower into another room..
Sharp temperature drops should also be avoided. Stable living conditions - a pledge of health and beauty of this flower.
Another mistake in the care of dracaena is frequent and abundant watering. This can easily lead to root decay even in the summer hot period.
And in the winter, when the plant is kept at a low temperature, the risk of root rot increases much.
The rotting of dracaena roots immediately leads to changes in the ground part of the plant.. Its leaves begin to turn yellow, dry and fall off, and not only old, but also young leaf blades turn yellow.
Do not water the flower if the top layer of the earth is still wet.. The land in the pot between waterings should dry at least 2 cm. Therefore, even in very hot weather, the dragon fruit is watered no more than 2 times a week, and in winter the intensity of watering is reduced to 3 times a month.
If decay has already occurred, transplant the dracaena into new soil.y A new pot needs good drainage, which will not allow water to stagnate. When root rot is carried out a full transplant dracaena with the removal of the earth and a thorough examination of the root system. All rotten, dark and dry roots should be removed.
Lack of top dressing
In order for the dracaena to look beautiful, it requires regular feeding. In spring and summer the dracaena is fed twice a month..
If fertilizing is not carried out regularly or is completely absent, the plant does not receive enough nutrients for its growth. This leads to the fact that it loses the lower leaves much faster than in the normal state.
If the dragon tree has not been transplanted for a long time, its roots become cramped in a pot. They begin to surface and through the drainage hole.
Without a graft, potted soil gets very depleted, the plant does not receive normal nutrition. Because of this, the flower intensively loses the lower leaves. If the dragon tree is not transplanted for a long time, it may die.
Feeding will not help here. Young specimens need to be transplanted each year in a larger pot and new soil. It is enough to replant adult plants every 3 years.
The presence of pests on the leaves of a plant can lead to yellowing. On dracenes parasitize: red spider mite, mealybug, thrips and scythe.
Often the pests are hidden in the leaf axils, so it’s difficult to notice. Insects feed on plant sap, which leads to yellowing of leaves and the appearance of dry and dark spots on them.
If the leaves of dracaena turn yellow, but there are no errors in the care, it is necessary to examine the plant for the presence of pests. All yellow and dry leaves are removed, and the rest are examined under a magnifying glass.
If there is a web on young shoots, powdery white bloom or dark spots - the plant is affected by harmful insects.
To purchase pest control, it is necessary to use only purchased insecticidal preparations., as folk remedies completely destroy pests will not work. The plant must be treated with pesticides, and after 7-10 days, repeat processing.
Diseases and pests
Dracaena often dries due to the development of disease. One of the common problems is considered a bacterial infection. Such changes are observed when creating unfavorable conditions for the plant:
- excessive humidity in the room
- plentiful watering
- deficiency of nutrients
- placing the plant in an alkaline substrate.
Another reason for the sudden appearance of yellowness is the decay of the root collar. Also, flowers begin to wither as a result of attacks of spider mites and scutes. A parasitic on a palm tree can be a powdery mite and thrips. It is noted that the leaf plates twisted and changed the color shade.
First aid measures
Having found out the exact reason why the leaves fell off the palm tree, you need to take measures to reanimate the plant:
- Place the pot on the windowsill, hang the window with light-transmitting fabric and prevent drafts.
- Create optimal temperature conditions (20-25 degrees). Low and too high thermometer rates are extremely undesirable and can aggravate the situation.
- Spraying and a warm shower will help to save the dracaena in case of excessively dry air. After carrying out water procedures, it is necessary to dry the foliage of the foliage with a napkin.
- In case of rotting of the roots, an urgent transplant is carried out. The affected parts are cut, and healthy areas are covered with wood ash or activated carbon. If the palm tree has become more yellow after transplantation, it will have to be helped by radical methods. An overly damaged measles system is unable to recover. It is necessary to trim the tip and root it.
- Watch for watering. Moistening is done every 2-3 days.
- Fertilize the soil regularly using nitrogenous fertilizers. At the same time, it is necessary to prevent substrate oversaturation with useful substances.
- In case of burns, transfer the flower to a shaded place. It is imperative that the lighting was scattered.
- In the case of a natural drop of the bottom sheets, simply cut off the color-changed specimens.
- If a plant is damaged by pests, it is immediately treated with soapy water and washed under a shower. After that, you should use special tools to help get rid of parasites.
The yellowing of the foliage of the dracaena is a fairly common problem, but in most cases it can be solved. The main thing is to immediately find out what caused such changes. Only then can you take decisive action. The main task is to eliminate the factor aggravating the state of the palm. Only with this it will be possible to achieve a positive result and save the flower from death.
Wrong location selection
Yellowed sluggish leaves on the top of the crown may indicate a draft or movement of air of another origin - for example, from an air conditioner. In the place where there is a pot with a flower, there should be no air movement, especially with changes in temperature. At the time of airing the plant is better to remove from the window sill, especially in the cold season. Dracaena will suffer less from temporary movement than from a jet of cool air.
It is very bad if direct sunlight hits the plant - from this the dracenes turn yellow and the leaves fall, but first brownish spots appear on them. Tropical plants need a lot of light, especially its variegated varieties, and it must be scattered. From the lack of light leaves dry, starting from the edges.
Dracaena loves moisture, with insufficient watering, leaves dry and fall. However, trouble can also occur if moisture accumulates too much in the ground. Therefore, it is necessary to check the condition of the soil before watering: in the summer, 2-3 cm of soil should dry out, and in winter you can check the depth with a wooden stick.
If water remains after shower or spraying in the axils of the leaves, it may cause them to rot. The first "bell" will be yellowing, lethargy.
Poor quality soil
Young palm is transplanted annually, because it does not have enough space in the old pot. The adult dracaena grows much more slowly, but it also needs to be transplanted every 2-3 years or even more often. After long-term use, the soil is depleted, loses its friability, begins to retain excess water. In addition, after watering in the ground, a lot of salts are deposited, which make it difficult for the roots to absorb nutrients. For this reason, the earth needs to be changed more often, but do it very carefully, because the roots are fragile, they are easy to damage.
The plant should be fed on time - the tips of the leaves turn yellow, often due to lack of nutrition. Dracaena turns yellow, loses color saturation and with a lack of nitrogen. It is also impossible to overdo it - an excess of nitrogen reduces resistance to fungal diseases.
If the soil was chosen incorrectly, this will also affect the appearance of the palm tree - it sheds leaves if the soil is alkaline or too acidic. The soil must be sufficiently loose, contain nutrients, at the bottom of the pot there must be a quality drainage layer.
Dracaena leaves also fall due to illness. Fungal diseases spread at low temperatures and high humidity. On the leaves, they appear as brown or yellow spots, dryness along the long edge. To fight apply fungicides. Worse, with bactericidal diseases, it is almost impossible to cure them, it is easier to save the unaffected part of the top by cutting off and rooting in the new soil.
When the root system is rotting, the plant quickly fades, the leaves lose their turgor and the trunk becomes soft. A sufficient amount of potassium phosphate fertilizers can protect the root, make the plant stronger.
Dried green parts with the defeat of pests that suck the juice out of them.
How to save leaves
If you find the reason why dracaena leaves dry or turn yellow, you need to urgently rectify the situation in order to save the plant.
The optimum temperature of the content is + 20-25 ° C. The flower should stand on the window sill or near it in order to receive a large amount of diffused sunlight. It is on such a place without drafts you need to rearrange the pot.
Frequent spraying with separated water, a warm shower, after which you need to dry with a sinus napkin, will help to save from a lack of moisture. An urgent transplant will save you from overwetting and rotting of the roots, and the roots should be cut to healthy parts, powdered with activated charcoal.
Aphids thrips, spider mites, shield can be removed from the plant with soap and cotton wool. Then the plant should be washed, if necessary, treated with appropriate preparations.
The plant will always be healthy and beautiful, if it creates a comfortable environment, watered, fertilized and transplanted on time.
