Dracaena (dragon tree).
Dracaena - one of the most spectacular decorative foliage plants in the family dratsenovyh. Most dracaena comes from the tropics. To dratsenoy include about 150 species, native to - tropical and subtropical Africa and the islands of Southeast Asia.
Some adults mistakenly called dracaena palm confused with yucca, often referred to as dratsenoy kordiliny, and vice versa. Scientists have long figured out systematics systematic position of dracaena and kordiliny. According to the latest information in a systematic, dracaena and kordiliny belongs to the family dratsenovyh. But in order to avoid mistakes in the care of these plants need to be able to distinguish from dratsenu kordiliny.
In decorative floriculture Dracaena from kordiliny distinguish the roots. Do dracaena roots orange-yellow and smooth, while the rhizomes kordiliny white and thickened. Leaves sessile dracaena (ie without cuttings), linear, leathery, with parallel veins. In some species, dracaena leaves collected beam on the top of the stem, while others are located around the stem or spiral whorls.
An old Indian legend tells that a long - long time on the island of Socotra, which is located in the Arabian Sea, there lived a powerful bloodthirsty dragon. He got into the habit of elephants attacking and drinking their blood. But one day an old and powerful elephant, defensively, fell to the dragon, and crushed him. Their blood will be mixed and moistened the soil around, and after some time on this site have grown trees, named with dragons, or dratsenoy, which translated from Greek means "female dragon".
On tree dracaena appear red spots resinous juice, which the locals call "the blood of the two brothers" or "vermilion", and one of the dracaena is called "cinnabar-red." In 1402, opened the island of Tenerife, where high on the mountain grew oddly shaped tree with a thick trunk and a large hollow inside. Its height was 23 meters, diameter - more than 4 meters in circumference of the barrel - 15 meters. Locals believed the sacred tree, was placed inside the hollow of his altar. And now on the island grow dracaena somewhat smaller.
Nowadays dracaena are decorative ornament homes and offices. Their exotic look attracts both professionals and amateurs - florist. Care dratsenoy is quite simple: these plants are undemanding and relatively hardy.
Many of dracaena plants speckled leaves. Such dracaena be kept in bright light, so that their leaves do not lose your image. Zelenolistnye Dracaena have a light, but protected from direct sunlight. Optimal for dracaena summer temperature 18 - 25 degrees. Hardy Dracaena (dragon tree, Dracaena fragrant, dracaena Hooker) feel well in the open air, protected from drafts place. This plant cold greenhouses; in winter they quietly tolerate temperatures 12 degrees or even lower.
Watering and fertilizing.
It is necessary to maintain a uniform humidity of the substrate in a pot with dratsenoy but avoid waterlogging. Drying earthen coma is also undesirable. At low temperatures, the content should be kept to a minimum watering dracaena, alternating it with a slight loosening of the soil. The air in the room needs to be damp and warm; when it gets too hot, you need to spray the plant once a day.
Frequent spraying dracaena - a kind of prevention against the appearance of spider mites. From my own experience I can say that in the summer for dracaena foliage is very useful light shower, but it is certainly necessary to close the ground with a plastic bag to keep it with excessive. Summer once a week is necessary to the water Dracaena add a few drops of liquid fertilizer. Fall and winter dressing Dracaena should be made less; need less watering and dratsenu but earthen room should not be too dry.
Dratsenu can be transplanted in the spring every two years or, if it is growing rapidly every year. For transplantation Dracaena take pot large size, the bottom as a drain put shards or pebbles, and then the mixture on the basis of land or peat. Recommended earth mixture: equal amounts of turf, leaf soil, humus, peat and sand. Dracaena roots need space; pot with a diameter of 15 cm for 40-cm plants.
Most dracaena very easy to propagate. Possible reproduction of dracaena seeds, cuttings, and parts lignified stem. The cut of the lignified stem Dracaena pieces treated in places cut paraffin, easy to carry transport may lie long before that time, as will be the planting material. Seeds were sown in March Dracaena at a constant temperature of + 27 degrees. As soon as the young plants are a little older, they are transplanted into individual pots with a diameter 7cm, kept at a temperature not lower than + 21 to +24 degrees.
Take cuttings from the top or side stems of dracaena, pluck from the trunk of the old leaves. Stalk Dracaena separated into pieces 7cm long, the lower section of each of the cutting process kornevin and planted cuttings in a mixture of sand and peat, kept at a temperature no lower than 24 degrees. When rooted cuttings of Dracaena leaves appear, they are transplanted into pots.
Hazards and the measures taken.
Care should be taken so that the soil in the pot with dratsenoy was not flooded or retain moisture; Glaze should be regulated so as not withered leaves of dracaena. At low temperatures also occurs podvyadanie Dracaena leaves, in this case, the plant should be rearranged in a warm place. In any case, do not allow stagnation of water in the pot, so the roots of Dracaena easily rot, which is the main cause of death of adult specimens.
Brown tips or edges of leaves of dracaena indicate that the air around the plant is too dry, the other reason - cold drafts or insufficient irrigation. Brown spots on the leaves of Dracaena also indicate a lack of watering, light dry spots - an excess of sun.
Soft twisted leaves Dracaena indicate that the temperature of the content is too low; with delicate species of dracaena like symptoms appear, if you leave the plant near the window on a cold night. Slowly yellowing leaves of dracaena - a natural and inevitable process for old plants. This is explained by the fact that the leaves of dracaena short-lived: in two years, they turn yellow and die. Pests dracaena can be called mealybugs, scale insects, spider mites.
Mealybug - a slow-moving insect whitish or rozovovatogo color. On the leaves of plants, and in the center you can see the sockets Dracaena wax selection, similar to small pieces of cotton wool. Mealybug wash off with soap and water (20 g of soap in 1 gallon of water, it is best to use a liquid potash soap). Plants 2-3 times at intervals of 5-10 days sprayed aktellikom (2ml / l).
Scale insects on the leaves of Dracaena looks like a oval plate (2-4 mm) grayish-white or yellow. Schitovkami carefully removed from the leaves, then leaves rubbed with a cotton swab dipped in vodka. Can be treated with insecticide dratsenu.
Spider mites - small (0.2 mm) yellow-green insect. As a result of vital activity of mites on the underside of leaves of dracaena have yellow spots. The leaves are rubbed with a cotton swab moistened with hot water (50 degrees) with soapy water (20 g of liquid green soap to 1 liter of water) or spend processing acaricides.
