What to do if the leaves of the dragon s blood tree turn brown and dry up?

Lack of nutrients caused by supplementation of some phosphate, nitrogen, potassium fertilizers.

Plants are one of the main forms of life, including trees, shrubs, vines, grasses, ferns, and familiar organisms such as green algae and lichens.

Most of the energy of green plants is obtained from sunlight through photosynthesis, and temperature, humidity, light, and fresh water are the basic needs of plants for survival.

Seed plants have six major organs: roots, stems, leaves, flowers, fruits, and seeds. Green plants have the ability to photosynthesize - with the help of light energy and chlorophyll, under the catalytic operation of enzymes, water, inorganic salts and carbon dioxide are used for photosynthesis, releasing oxygen, absorbing carbon dioxide, and producing organic matter such as glucose for plant use.

In nature, all living organisms belong to living things. Organisms should be divided into several kingdoms, and the sedentary and autotrophic organisms are called the plant kingdom, referred to as plants.

Plants have distinct cell walls and nuclei, and their cell walls are made up of grapes.

Sugar polymers – cellulose composition. Plants have the ability to photosynthesize – that is, they can use light energy and chlorophyll that animals don't have in their bodies to produce food from water, minerals and carbon dioxide.

After the release of oxygen, glucose – an energy-rich substance – is left as a building block of plant cells. [1] Aristotle distinguished between plants (which are usually immobile) and animals (which often move to obtain food).

In the Linnaean system, it is divided into two kingdoms: the plant kingdom and the animal kingdom.

Later, it became known that the original definition of the plant kingdom included several unrelated taxa, and fungi and several species of algae were moved to the new realm. However, there are still many opinions about plants, both professionally and in the eyes of the general public.

It is also true that trying to fit "plants" perfectly into a single taxonomy is problematic, because for most people, the relevance of the word "plant" to the concept of phylogeny, which is based on modern taxonomy and phylotaxonomy, is not very clear, and the methods of reproduction are mainly striping, dividing, cuttings, grafting, seeds, etc.

The yellowing and withering of the leaves of the dracaena tree may be caused by too much light, and corresponding shading measures need to be taken. It may be caused by the low temperature and need to be moved indoors to keep warm. It can be caused by overwatering, and watering should be stopped immediately and the soil should be loosened.

It may be caused by too much fertilization, and fertilization should be stopped and the amount of watering should be expanded.

Airy. In the process of cultivating dracaena, if it is kept in a poorly ventilated place, it will cause the leaves to turn yellow, and it is also easy to breed some pests and diseases. Therefore, when cultivating dracaena trees, they must be kept in a well-ventilated place, especially in the hot summer.

Illumination. The most common reason why the leaves of the dragon's blood tree are dry and yellow is because of too much sunlight. Because the dragon's blood tree itself likes light, it can carry out photosynthesis well, but if it is kept in a place with too strong light for a long time, it is easy to burn the leaves, so that it can cause dryness and yellowing, so it can be moved to the place where the light is scattered.

Watering. When many people breed dracaena, because of their love for it, they often water it, and over time, their roots will not be able to breathe well, and the leaves will appear yellow and dry. Therefore, in the process of breeding, you can wait until the soil is slightly dry before watering thoroughly.

Pests and diseases. In the process of raising dracaena, it is easy to breed some pests and diseases, and when it suffers from germs or insect infestations, it will make the leaves dry and yellow, so it is necessary to spray some insecticides in time. In addition, some fungicides can be sprayed at intervals of half a month, which can achieve the effect of pest control.

Reason: Dracaena prefers sunlight and a moist growing environment, and if it is left in a cool place for a long time, the leaves will turn yellow.

Solution: To let it fully receive sunlight, but also to ensure that the breeding environment is moist and warm, you can directly put it on the balcony, with good sunlight and ventilation.

Reason: If you don't change the pot for a long time, as its roots continue to grow, the space in the pot will be insufficient, it will not be able to absorb nutrients, and the leaves will naturally turn yellow.

Solution: Replace the pot in time according to its growth state, be careful when changing the pot, and try not to hurt the roots.

Reason: Dracaena prefers a warm environment, and if the temperature is too low, the roots will not be able to absorb water properly, so the leaves will turn yellow.

Solution: Take some warm measures when the temperature is low in winter, and do not put it directly in the place where the air conditioner blows directly in summer, so as not to affect its normal growth due to low temperature.

Reason: Spider mites are easy to appear due to the breeding environment, and the leaves of dracaena trees will turn yellow or even fall off when they are infested.

Solution: After discovering the presence of red spiders, it is necessary to catch them in time, which is generally more convenient to capture manually, and can also be eliminated with chemical agents.
