Dracaena, or false palm, is one of the most popular decorative cultures and is often grown at home for interior decoration, and is also widely used in landscape design. Gross violations of care and transplantation technology often lead to the fact that the leaves of dracaena turn yellow, dry and fall off.
The most dangerous cause of yellowing, wilting and falling of foliage of dracaena is the defeat of the decorative culture of pathogenic microflora or infectious diseases:
Subject to the cultivation and care technology, dracaena are rarely affected by plant parasites. Nevertheless, it is important to regularly inspect ornamental plants and, at the first sign of pests, use the most effective therapeutic measures. In rooms with too dry air, spider mites may appear on the aerial parts of the plant. Regular airing of the premises, as well as frequent spraying of the aerial parts of the tropical decorative culture with standing water at room temperature, avoids the damage of plants by this dangerous pest.
Occasionally, false palm trees, especially those grown under indoor floriculture conditions, are damaged by scale insects, mealybugs, thrips and nematodes. Depending on the species, thrips are able to affect mainly inflorescences, foliage or the whole aerial part of the culture.
The problem of thrips damage also lies in the ability of the plant parasite to carry some viruses that are dangerous to the false palm. After treatment with chemical insecticides, the place where there was a flower pot with a thrips-affected plant must be thoroughly cleaned and the upper soil layer replaced.
The fight against plant parasites must be comprehensive. Adult pests are previously removed manually using a cotton swab moistened with plenty in any alcohol-containing liquid. Then the aerial part of the plant is thoroughly washed under warm running water and treated with such chemicals as Actellik, Fitoverm or Fufanon.
As a rule, dracaena are affected by diseases, the cause of which lies in improper care or inappropriate conditions for the growth of a tropical plant. With a gross violation of growing technology, the following problems may arise:
The appearance of dry tips on the foliage most often indicates excessively dry air and insufficient moisture in the soil in the flower pot. Yellowing of the lower, already old foliage is a completely natural and inevitable process that does not require intervention. In this case, the shrunken leaves just need to be carefully cut.
If young foliage turns yellow, then first of all you need to pay attention to irrigation activities. The soil mixture in the flower pot must be sufficiently moistened, but irrigation is carried out with standing water at room temperature only after the top layer has dried, which will reduce the risk of soil moisture and rotting of the root system. The cause of yellowness and drying of foliage on a false palm can be the negative effect of drafts with insufficient watering.
The absence of a temperature regime that is comfortable for a tropical plant can cause softness and curl of foliage, and the formation of brown bordering on the leaves. The cause of the formation of dry and bright spots on leaf blades is often an excessive amount of direct sunlight. In this case, you need to install a flower pot with dracaena in a less lighted place. It is especially important to understand the reasons if the plant died. This situation arises with excessive watering in the winter and prolonged exposure to low temperatures.
Improper planting and planting often provoke a decrease in the decorativeness of the plant, which can manifest itself in a change in staining, drying out or falling of the foliage. The acquired dracaena must be subjected to a mandatory inspection. and evaluate not only the state of the decorative culture, but also the suitability of the flower pot and soil for subsequent cultivation.
Very often, tropical plants are sold in a special transport soil, which is completely unsuitable for further cultivation of false palms. In this case, it is necessary to transplant with the replacement of a nutrient substrate, and sometimes a flower pot, which should not be plastic, but rather heavy clay or ceramic.
The transplantation of dracaena, grown at home, must be carried out by transplanting the plant, so that the roots of the decorative culture will be minimally injured. Transplanting part of the plant is not required. Young indoor dracaena transplant after about a year, and adult specimens are transplanted no more than once every three or four years. Street false palm can be transplanted as needed.
For the cultivation of false palms, it is advisable to use special planting mixtures intended for cultivating the palm family. Self-made soil should contain four parts of turf land, a couple of parts of leafy soil, a couple of parts of humus and one part of peat crumb. The plant without fail needs to provide high-quality drainage, without which the entire root system decays, and the false palm can die in a short time.
