Diplomatic for its beauty and fragrance is rightly called a "paradise" plant. Spectacular large flowers of different tones with regular and semi-double petals thickly cover the stems, clearly looming on the background of glossy foliage. In skillful hands, a flower can transform into a lush bush or into an elegant liana that will bloom until late autumn - even on the balcony, even in the garden. Culture is not easy to care for. That is why some new growers are afraid to acquire it. In fact, not everything is as difficult as it seems at first glance. Let's try to figure out with the experts that it prefers diplomatic arrangements, what features and difficulties in its cultivation.
Did you know? In the botanical literature, the plant is designated by two different names: “diplomatic” and “mandeville”. This is due to the fact that the flower was opened twice. At first, scientists discovered it in Brazilian forests and called it "deplodenie", which in Greek means "one that has two nectaries." Some time later, another expedition discovered culture in Argentinean lands, which registered it as a new genus and assigned a name in honor of an English diplomat, an ardent collector of ornamental plants, Sir Henry John Mandeville. Modern botanists have fixed a mistake by combining the two breeds into one, but they have never thought up a common name.
Comfortable conditions for growing diplomatic in the house
In the natural environment, wet forest lawns, protected from the burning sun rays and winds, are common for a gentle diplomatic. In our latitudes, it will not be able to bloom all year round due to the short daylight hours. But if you provide Mandeville competent care at home, it will not disappoint.
Selection and lighting
The room is ideal for diploadiya fit east side. A gentle morning sun will give the flower enough warmth and light. On the southern windows, the plant will constantly struggle for survival, as it will feel constant discomfort, especially in hot weather. From overheating, its foliage may turn yellow and flower stalks fall off. If the stems are very long and few buds have formed, the mandeville flower is poorly lit. 
The amount of light received is of particular importance in the period from mid-spring to mid-autumn, when the pot is blooming. Experts advise in the summer to put the plant in the garden under the branched tree. There diplomatic deposits will be sheltered from drafts and direct sunlight. Some florist for the season planted it with a pot. According to experts, this should not be done, since on cold nights the plant is being seriously tested. As a result, it can stop blooming.
If the flower is grown in the conditions of an apartment, in the summer it will be comfortable on a slightly shaded balcony. Regular airing is also important. In winter, the culture needs additional lighting and moisture. With the help of fluorescent lamps, working for 14 - 16 hours, with proper care, you can achieve year-round flowering. But this hard work can only be done by experienced flower growers. In most cases, lovers of decorative gardening suspend the development of culture, sending it to a state of stagnation.
Did you know? Loving Latin Americans call diplomacy “Brazilian jasmine”, “Bolivian rose” and even “Mexican tree of love”.
Temperature conditions
Heat-loving mandeville for full development it is necessary to ensure the temperature regime in the range of 20 - 26 degrees. By the way, the higher the temperature, the brighter the color of the petals. In the shade in summer, the plant can even adapt to the 36-degree heat, and in winter the thermometer mark should not fall below 15 degrees. This is the optimum temperature for a hibernating pot. If you set a goal to achieve year-round flowering, the room temperature should be at 25 degrees.
Rules for the care of diplomaenia at home
If you know how to care for decorative people from tropical latitudes, then diplomatic rights will not give you additional trouble in care and cultivation. This flower needs enough moisture in the soil and air, timely feeding and forming pruning are needed to support the decorative form.
Watering and humidity
For good growth the flower needs moderate systematic moisture, loose soil and good drainage. Soil between watering should be slightly dried. During the growing season, the amount of water absorbed by the roots increases. The plant does not like swampy substrate in a pot, in such conditions it can get sick and die. Make sure that at the bottom of the tank there are special openings for draining excess water into the pan.
Humidity is also moderate. In the summer, one or two irrigations per day are sufficient. Since the beginning of the period of stagnation, the plant is watered less often, reducing to once a week. In winter, the pot is kept in cool conditions, they are watered only after the land has dried in the pot and is not sprayed until awakening.
Water for moistening should stand and be at room temperature. It can be slightly diluted with lemon juice or acid, since Mandeville prefers an acidic environment. Acidification can be carried out even with vinegar, provided that the water for irrigation is well settled and loses odor. Not suitable for watering hard water with a significant amount of lime. It is better to irrigate and irrigate the southern beauty with rain water, and in flat conditions it is recommended to boil tap water and let it stand.
Important! In winter, the depository is removed away from the central heating radiators and heaters.
Top dressing of a flower
Fertilizing the flower is recommended at the beginning of the growing season, when buds are formed and during flowering. Begin monthly feeding from the moment of active growth of the plant, making every week complex mineral fertilizers. Alternatively, any nitrogen-containing supplements will do. In the future, when green biomass develops sufficiently, the plant must be watered with a phosphorus-potassium solution. Feed continues until the dormant period. Diplodation in winter in terms of growth inhibition does not need good nutrition.
Support
Given the ampelous properties of Mandeville, no matter what form you dress it, you should take care of reliable supports for the flower. Even if in the future you see it only a small bush, props for tender stems are required. In its natural environment, the vine is drawn up to two meters. It can reach the same length in favorable conditions at room cultivation. When buying a ladder for diploadia, consider its age, length of sprouts and root system, as well as the volume of the pot.
Pruning
Tropical guest is developing very quickly. A small sprout after planting soon branched out strongly, but not all shoots manage to bloom before the period of stagnation.
Inexperienced growers are sometimes lost: what to do with a liana that has lost its shape, how and when to trim diplomatic. All the more, a non-cut plant hibernates poorly and loses its decorative effect.
Pruning recommended after flowering before the beginning of a period of calm. Optimum dates: mid-October - early November. First of all, 2/3 sprouts are removed, which did not have time to develop. Then proceed to the formed stems, shortening them by a third or half after the fork. In spring, expect the appearance of buds only on young branches. This fact is worth considering when forming a flower-shaped crown. Experienced gardeners refuse it, because they do not want to sacrifice the main advantage of culture - its flowering. It is better to form a compact crown by winding the pruned sprouts on a support.
Important! In contact with skin, Mandeville juice causes severe allergic reactions and burns. Therefore, all work should be carried out in gloves, and after the procedure, thoroughly wash the shears and hands.
Features care in a dormant period
In the winter, diploadineniya often suspend the growth of shoots, reducing the number of waterings. As a result, with insufficient light of the bottom of the plant hibernates until spring. Previously it is cut and sent to a cool room, where the temperature is not lower than 15 degrees. It is strictly not recommended to put a container with an earthen tuber on a window sill in a cold room or on a balcony. Supercooled soil will inevitably lead to the death of the roots.
Mandevilla is poured over at rest as the ground is dried in a pot. Spraying and dressing stop altogether until full awakening.
Fight against diseases and pests
Gentle mandeville is extremely sensitive to cultivation conditions. The slightest flaws, especially in winter, are fraught with the development of root nematodes, which is manifested by the withering of stems and the formation of galls on rhizomes. To save an infected flower, unfortunately, is no longer possible.
All diseases of diploadia are caused by improper care. Insect pests of the flower are spider mites and mealybugs. At the first signs of their vital activity, the stalks should be treated with the insecticides "Aktellik", "Aktara", "Agravertin". Do not forget to regularly inspect the pot. Often, indoor plant lovers pay attention to the problem when the deposit has already turned yellow and the leaves have fallen off or the flower stalks have withered. And in fact, the reason for this behavior was in the wrong temperature.
With a lack of light, the leaves become a pale lifeless color, the pot does not bloom. If the leaves are rushing down, and young cuttings fade, it is worthwhile to increase the humidity in the room and the soil. Do not interfere with additional feeding. Twisted semi-dry foliage indicates dryness in the room and the wrong arrangement of the flower.
Perhaps he is under direct ultraviolet rays, it is hot. If the dry deposit dries, look: if there are any pests on it, if the roots have not rotted from an excess of moisture. If you are sure that you did not make mistakes in the care, and did not detect the vital activity of harmful insects, the cause of flower discomfort in a poor-quality substrate. Pot need to transplant.
Did you know? The ancient tribes poisoned the juice of the depository smeared arrows for hunting game. Contemporaries have learned to use poison in the treatment of urological and heart diseases.
When and how to transplant: soil and pot for growing
Mandeville needs a transplant as the root system grows. This is evidenced by the roots sticking out of the drainage holes. The ideal capacity for landing is 30 cm in diameter and 15 cm deep. It is important to take this into account in order to avoid problems with the adaptation of the supports.
It is characteristic that young plants root and grow better in peat substrates, and more mature specimens in turf. In all cases, the land for transplantation should be enriched with useful substances, slightly sour. Universal soil is prepared from equal parts of river sand, humus, peat, sod (hardwood) soil. All components are well mixed, loosened. At the bottom of the tank, which is several centimeters more than the previous one, clay or brick chips are laid. If transplantation is not caused by plant diseases, the earthen tuber is transferred to a new pot and the upper layer of soil is renewed.
Transplantation is better to do in early spring.
Grafting diplomatic
At home diplopentine reproduction is characteristic of cuttings. Young sprouts in the spring are cut from the mother bush, leaving three to four leaves on the cuttings. For rooting, the branches are placed in a peat substrate and covered with a plastic cup or plastic bag. Capacity put in a warm place for a month and a half. At the same time the greenhouse is regularly watered and ventilated.
When the cuttings are fully rooted, they are planted in separate containers. In one pot you can put several stems to create a dense flowering crown.
