Dracaena is grown due to its beautiful appearance and pleasant smell. The plant has long or narrow green leaves and buds of yellow, white, pink color, collected in panicles. However, the flower may lose its decorative effect. Many are worried about why dracaena lowered leaves.
Dracaena leaves fall - what could be the reason
First of all, you need to know that regular falling of the lower leaves and their yellowing is a normal phenomenon that will accompany the flower throughout its growth. On average, the maximum age of a single leaf is 2 years. After the death of the old foliage, a new one will appear.
The appearance of dracaena
However, in dracaena, the leaves fall down not only for a natural reason. If over time a large part of the foliage will fall, then you should be wary. Another reason could be:
- passing the period of acclimatization;
- damage to the root system;
- violation of the rules of agricultural technology;
- attack by a dangerous pest;
- disease defeat.
Important!The leaves of the plant in the normal state are usually directed upward, forming an acute angle with the trunk.
The plant purchased in the store must adapt to new home conditions. At first, the level of illumination, humidity and air temperature in the room will affect the well-being of the flower. If the recently purchased dracaena lowered the leaves, then there is no particular reason for concern - this is temporary.
Diseases
Improper care or transplantation can lead to the appearance of various diseases in a plant. A flower with reduced immunity is susceptible to fungal, viral or bacterial diseases.
Alternariosis
The causative agents of this disease are fungi assigned to the genus Alternaria. An infected flower on the leaves will first notice round spots of a pale brown hue. After some time, they will turn black. Ultimately, the part of the leaves covered with these spots will begin to die. From the outside, the leaves are covered with olive plaque containing spores of the pathogen.
The drug Fundazole against Alternaria
At the first signs of the disease, the flower is transferred to a free windowsill away from other plants and wiped with foliage infusion of wood ash. Dracaena can be cured with the help of the drugs Fundazol, Topaz or Oksikhom. Dosage - 10 g per 0.5 l of water.
Attention! The flower must be sprayed 3 times with an interval of 10 days.
Phyllosticosis
This is a fungal disease that most often affects adults and old flowers. It appears on the leaves of the plant in the form of blurry beige-brown spots with a rim of lemon-green color. Over time, they will turn into small black grains.
To cure a bush, you need:
- Remove infected areas. Heavily affected leaves should be completely cut off.
- Sprinkle places of cuts with activated carbon powder, chalk. For processing, you can also use iodine or brilliant green.
- Spray the plant with a solution of Topaz or Skor. Spraying is carried out 3 times with an interval of a week.
Important!During treatment, any biostimulant is added to water for irrigation. The most popular are Zircon and Epin.
Bacteriosis
It is an infectious disease that affects different parts of the plant. The tips of the fading leaves become dark brown, small ulcers appear on the trunk and petioles, and the crown turns yellow.
A yellowish oily strip will separate infected tissues from healthy ones. The root system also suffers from the disease if the room is hot and the soil is waterlogged.
A plant infected with bacteriosis cannot be healed. You can cut a healthy shoot without the characteristic signs of the disease and try to root it.
Fusarium
Yellow spots on fading leaves indicate infection with this fungal disease. The plant will begin to gradually change its color to brown.
Damaged leaves are removed, and the sections are treated with activated charcoal or cinnamon. The bush is sprayed with a solution of Fundazole, Benomil or Vectra.
The procedure is carried out 2-3 times with an interval of 3-5 days. For preventive purposes, Fitosporin-M is introduced into the water for irrigation.
Attention! It is also useful to transplant the plant into new soil treated with Gumistar solution.

Pests
Due to harmful insects, dracaena can get sick and drop leaves. Eliminate parasites immediately after detection. The most common pests are scale insects, spider mites, aphids, mealybugs.
Shield
The presence of the pest is indicated by rounded brown plaques 1-3 mm in diameter, covering all parts of the plant. They are used by the pest as a shelter.
The leaves will acquire a yellow-red hue, begin to sink, dry and die. The insect itself can be eliminated manually with a sponge soaked in soapy water.
Attention! The most effective method of control is to conduct treatment with Aktara 2 times at weekly intervals.
Spider mite
This small insect 0.5 mm in size is painted yellow-green. It is very difficult to see. The tick settles on the inside of the leaf, where white spots will appear over time.
Damaged areas are covered with formations resembling cobwebs. Leaves may turn yellow and darken.
Treatment of dracaena consists of treatment with a soapy solution heated to +50 ° C and spraying with Actellik or Fitoverm. Spraying is carried out only after the bush dries.
Aphid
Small pests severely damage the upper parts of the shoots and the lower parts of the plates, sucking out cellular juice from them. Infected leaves lose their color, turn yellow and fall off. Timely treatment will help prevent plant death.
Insecticides are used to combat these pests. The flower is treated with Antitlin or Biotlin every 5 days until complete recovery.
Mealybug
The pest infects leaf plates and leaf sinuses. In infected areas, you can see a wax discharge similar to cotton wool. The flower will have delays in growth and development. The bush is treated by spraying with soapy water. After that, it is treated 3 times with a solution of Aktar or Mospilan with an interval of 5-7 days. It is also worth updating the soil and transplanting.

Soil moisture
Despite the love of moisture, dracaena should not be constantly moistened. After each watering, you need to wait until the soil dries in depth by 3-4 cm.
For reference! The degree of drying of the soil is checked with a stick - it is stuck into the ground at 4-5 cm, removed, then look what state of the earth is on the tip.
An adult specimen is watered every 2-3 days in the summer. In winter, the frequency of watering is reduced by 2-3 times, depending on the age of the flower and air temperature.
Broadleaf representatives of dracaena have a high demand for moisture. In the summer they are watered daily. Narrow-leaved specimens consume much less water. They can be easily filled. Dropped leaves are the first sign of drying out roots. Regular spraying and watering will correct the situation.
Important!Do not forget about loosening the soil in the pot after each watering.
Air temperature
To the question why the dracaena hung leaves and what to do in this case, there is an answer. The reason may be in dry, hot air.
Regulation of air temperature will correct the situation. Then the plant will be able to pick up the leaves.
- In summer and spring, Dracaena feels comfortable at temperatures from +20 ° C to +25 ° C. If the air is even warmer, the crown will lose its beautiful appearance.
- In winter, it is permissible to contain a flower at a temperature of +17 ° C to +19 ° C. Do not allow the temperature to drop below +15 ° C.
Sudden temperature changes are also dangerous. If the flower began to drop foliage, then it suffered from hypothermia.
Root decay
The roots of the plant may rot due to waterlogged soil. This is another reason why dracaena leaves fall down. In a similar situation, the bush is transplanted into a new pot, previously disinfected with alcohol. It is important to get the transplant on time.
Transplanting dracaena into a new pot
You can save the flower by following these steps:
- Carefully pull the bush out of the tank and rinse off any remaining soil from the roots.
- Trim the rotten parts of the root with a sharp secateurs. At the same time, grab 3-5 cm of healthy tissue.
- Place the roots in a pink solution of potassium permanganate or Bordeaux liquid.
- Sprinkle the cut points with wood ash or colloidal sulfur.
- Transplant the bush into a sterilized container with new soil.
Important! Also, the culture is watered with a five percent solution of Previkur or Apirin-B for 3-4 months.
Other possible problems
There are other reasons because of which the leaves begin to fade and die:
- barrel damage;
- slow growth;
- redness of leaf plates;
- sunburn.
If the trunk is broken, then the place of the break needs to be leveled with a pointed secateurs. After the cut is sealed with wax. This will prevent it from drying out. A flower that grows slowly is transplanted into fertile soil and fertilized. The same thing is done in the case of reddening of foliage. The bush on the windowsill is sprayed in the evenings when the sun goes down so that the leaves do not turn yellow.
Now the florist knows why the dracaena have lowered leaves, what to do in such a situation. The above rules will help to revive the flower and it will again delight the owners.
