Radermacher: home care, cultivation, reproduction, species, photo

Variety of species

A total of 17 types of radermachers are described. Among them, the most famous are distinguished:

Radermachera ignea. Radermacher is fiery red. The plant is also known under the name "jasmine tree". It grows in Thailand, Laos, comes across in Burma and Hainan. It reaches 20 meters in height, it has carved foliage, oblong leaves 7 centimeters long. Flower buds originate on old lignified processes. It has racemose inflorescences of orange-red tubular flowers with petals opening outward. During the flowering stage, the tree is enveloped in a pleasant jasmine scent.
Radermachera ramiflora. Grows in forests in Borneo. Reaches 30 meters in height, the thickness of the trunk is 30 centimeters in diameter. The foliage is grayish, the flowers are yellow. Fruits are impressive in size up to 70 centimeters in length.
Radermachera xelocarpa. Radermacher is woody. Grows in India. Single-stemmed tree 5-10 meters high. With a very interesting crown during flowering. On the cracked old bark, between the bright emerald leaves, which are about 100 centimeters long, small inflorescences, consisting of funnel-shaped buds, bloom. The edges of the flowers are folded back and have an extensive wavy edging. The petals are snow-white, and the throat is creamy yellow.
With all the species diversity, only one species is grown as a home indoor flower - the Chinese Radermachera (Radermachera chinensis). It is distinguished by large glossy emerald-colored leaves, 70 centimeters long and 25 centimeters wide. The leaf is divided into several tiny leaves up to 4 centimeters long.

Radermachera (Radermachera) is an indoor evergreen tree that gained fame in Europe at the end of the last century, and has since become very popular among flower growers. It was brought from Asia, from the island of Taiwan, where it grew in natural conditions. The plant is named in honor of the botanist J. Radermacher who first described it, who studied new types of flowers back in the 18th century.

Radermacher belongs to the Bignoniev family and is distinguished by decorative foliage, it blooms extremely rarely at home. In nature, the radermacher grows up to 30 m, with a trunk width of about 1 m. People call it “Chinese doll” and “Snake tree”, for the glossy foliage of a beautiful dark green hue - “Emerald tree”.

Location and lighting

For good development and growth, a Chinese tree needs a bright place, excluding too active sunlight. Western or eastern window sills are preferred. On the south side, it is necessary to create partial shade to avoid foliage burns, which can lead to the death of the plant. In the winter months, you need to ensure that the amount of light is sufficient, otherwise the radermaker may lose its decorative shape.

In addition, it is necessary to rotate it around the axis for uniform symmetrical growth. This is especially true for the first year of life. The lack of light can be compensated by using fluorescent lamps or phytolamps during daylight hours.

Temperature

The air temperature in the room with the radermacher should be at the level of 20-25 degrees, in the winter months at least 10-14 degrees. The plant prefers fresh air without drafts, so do not place a pot of Chinese wood near air conditioners, vents and balconies.

Air humidity

Air humidity is not important for a radermacher - it adapts well to dryness, although moderate humidity is still preferable for it. To maintain it, the plant is sprayed; in the summer, even bathing in the shower is possible. Palletizing damp expanded clay, moss or pebbles will also maintain optimum moisture.

Watering

The radermacher should be watered abundantly and regularly with settled water at room temperature. By winter, watering is gradually reduced, without overdrying, but not overmoistening the soil in the pot. The substrate should be slightly damp at all times.

Top dressing and fertilizers

Fertilizers are applied to the soil about once every 2 weeks, using complex fertilizers for decorative leafy flowers. It is advisable to apply fertilizing after watering, so as not to harm the roots.

The soil

The soil for a radermacher should be fertile; a mixture of sod and leafy soil, peat and humus (1: 2: 1: 1) with the addition of sand is suitable. Or, you can use regular purchased land for ornamental plants and flowers.

Transfer

They are transplanted to the radermacher in the spring, every year, or as needed, if there is not enough room for roots in the pot. This can be determined by the change in the color of the leaves and the general sluggish appearance of the plant. The new pot should be more voluminous, and always with a good drainage layer, about 3 cm.

Reproduction radermacher

Reproduction of Radermacher Radermacher is possible by cuttings, layering and seeds. Cutting is carried out at the beginning of summer, cutting off the top of the shoots about 10 cm, and placed in a container covered with plastic wrap with sand and peat. The temperature under the film is maintained in the range from 22 to 25 degrees, the plant is periodically sprayed and ventilated.

For reproduction by layering, the stem is cut and wrapped in cellophane and moss, which is moistened from time to time. Roots will appear soon, and then you can separate the stem for planting in a separate pot. In order for the plant to take up well, it is necessary to wait for the entire package to fill with the roots, then the new tree will grow faster.

The seeds of a radermacher germinate for about 10 days, sow them in a well-fertilized moist soil and cover them with cellophane wrap. The seed method is rarely used, because it is quite difficult to grow them, and they are extremely rare on sale.

Diseases and pests

The Chinese tree is not prone to frequent diseases, but it can sometimes be affected by mealybugs as well. When these pests appear, an insecticide is used, diseased shoots and leaves are removed, and not heavily damaged parts can be treated with alcohol. After a week, the procedure is repeated.

Caring for a radermacher at home

Lighting

The emerald tree belongs to the light-loving indoor plants. The luxurious glossy foliage of this giant is afraid of direct sunlight, which leaves burns on them. But from the number of scattered locations, she puts up with both bright areas and light shading. The optimal mode of keeping for a radermaker is considered to be eastern and western window sills or locations in the interior near the southern windows, equal to the east-west in light intensity.

In the shade, the plants stretch out, the shoots become unpleasantly sparse, the beauty of the leaves is lost. But if you do not mind that the plant develops in the form of a vine, then you can safely expose the radermaker to partial shade of any intensity. Within the framework of locations from light to partial shade with young radermakers, you can experiment, trying to lower the illumination and watching how the plant develops, focusing in the selection of a location primarily on the decorativeness of the crown and its changes.

During the winter, it is necessary for the radermaker to provide a light correction associated with its seasonal reduction. From mid-autumn to early spring, it is better for the radermakers to provide a lighter location by placing plants even in sunny areas. Moving to a more illuminated place can be replaced with artificial supplementary lighting.

One of the essential nuances of growing this room culture is the need to take into account the light dependence of the radermacher. Plants must be regularly turned in relation to the light source in order for the crown to develop evenly

Turning is especially important for young crops, in which the main branches are just forming.

Comfortable temperature

It is very easy to find a comfortable air temperature for a radermaker.This woody feels great in the "room" ranges familiar to man, both in winter and in summer. The critical bottom for this thermophilic plant is 13 degrees in winter and 18 degrees in summer. Lowering below 10 degrees the radermaker will not withstand at all, up to 13 degrees will lead to growth arrest and partial loss of leaves.

In summer, this plant feels great in the range from 20 to 25 degrees Celsius; in winter, a temperature of 18-21 degrees is more suitable for a radermaker. It is not at all necessary to provide winter temperature drop. If the radermaker stays in a stable environment with an air temperature of 20 to 25 degrees all year round, the attractiveness of its crown will not be affected at all.

Radermacher belongs to houseplants that love fresh air. The room in which she stands can be ventilated as often as desired. At the same time, the plant responds well to temperature changes. But this woody with luxurious feathery leaves does not like drafts, it is better to protect the crown from them. In summer, the radermacher should not be exposed to the garden, but it will be comfortable on a sheltered balcony or terrace.

Watering and air humidity

The irrigation requirements of a radermacher can be called typical for most indoor plants. This plant does not like either the complete drying out of the earthy coma, or its waterlogging. The more stable the moisture content of the substrate, the more beautiful the radermaker will be and the less problems you will have in growing it. The soil inside the pot should always be slightly damp, but nothing more. Drying of the upper layer of the substrate serves as a guideline for the frequency of procedures. In summer, watering is carried out as soon as the top layer (centimeter) of the soil dries up. In winter, however, it is necessary to wait another 1-2 days after the top prodrug has dried.

For the radermakers, water at the same temperature as the air in the room is used throughout the year. She, as for all indoor ornamental-deciduous plants, should be soft and settled.

Despite their Asian origin, the radermakers have prepared a wonderful surprise for their owners in terms of air humidity requirements. These plants look most beautiful when these figures exceed 50%. But the radermacher does not tolerate dry air too badly; at the same time, the tips of the leaves are not prone to browning and the color is practically not lost. There is no need for a plant to systemically humidify the air.

Woody feels great in ordinary room conditions, while to maintain beauty, it is enough to periodically spray the greens of the radermacher from a fine spray bottle, and also not to forget about the need to rid the leaves of accumulated dust with a simple shower. For spraying plants, as well as for showering, it is advisable to use only room temperature water, not cold or warm.

If you are looking for a plant that can single-handedly create the effect of drowning in greenery, reproduce the "greenhouse" atmosphere of a delightful forest corner, communication with nature and living plants, perhaps the radermaker is the best choice (even in comparison with a variety of indoor ficuses and vines). In "atmospheric" only ferns can compete with this plant, but in the size of a radermaker they are significantly superior.

This is one of the most spectacular indoor woods with an openwork, translucent, but at the same time massive crown, capable of placing delightful green accents in the interior. The secret of the beauty of the radermacher lies precisely in the decorativeness of the luxurious, fresh leaves, which fill the whole house with harmony and seem to cut it off from the outside world. True, this plant, due to its size, affects the space somewhat overwhelmingly and it is more appropriate to use it in working corners and areas that need to be visually separated, made more secluded.

Radermachera (Radermachera) represents the Bignonium family among indoor plants. Like almost all shrubs and trees among them, the radermacher also represents Southeast Asia. The purely popular nicknames of the Radmachers are not limited to the "emerald tree" - Emerald Tree. This plant is also known as the China Doll and Serpent Tree. In nature, this evergreen beauty reaches 30 m and grows mainly upward, but in the room it is much more compact, with a height and width almost equal to each other.

The most beautiful part of the radermacher is undoubtedly the feathery, bright, with an emerald shade of color and a dazzling glossy sheen, large leaves growing up to more than half a meter in length and consisting of small oval leaf lobes pointed at the ends up to 4 cm long.In room culture, the radermacher does not bloom , but in nature it produces spectacular bells - large flowers with a grayish-yellow color, which bloom at night and exude the sweet scent of cloves.

Of a dozen natural species, the radermacher is used in room culture only one. Radermachera Chinese (Radermachera sinica) is a compact evergreen shrub, which is distinguished by a greater density of openwork crown than its giant counterparts in nature. Radermacher grows up to 1.5-2 m, is distinguished by a rapid pace of development, a powerful trunk branching from the very base. The leaves of this radermacher are complex, double or triple pinnate, grow up to 45-50 cm in length and adorn with graceful lanceolate lobes, jagged along the edge, bright glossy and rich green. Today, along with the classic radermachers, the variegated variety "Caprima" is very popular, combining bright light green and dark green and looking very catchy.

Radermachers are rightfully considered one of the most unpretentious large indoor plants. These beauties require substrate moisture control, but are otherwise completely undemanding and adapt quite well to typical room conditions. Radermacher does not suffer from one-time care mistakes, but requires a regular and systematic approach to growing. This plant retains its decorative effect throughout the year without exception, the dormant phase does not require the creation of any special conditions.

It will be possible for a radermaker to grow not only experienced flower growers, but also beginners who want to replenish their collection with a large plant. The most important thing is to choose the brightest possible pot for the radermaker (this plant is not afraid of even the most variegated patterns and flowers) and provide modest care.

Diseases and pests

Radermacher is not the most invulnerable indoor plant molestation. Mealybugs and spider mites love to settle in huge crowns. At the first signs of pest infestation, especially active in extremely dry air, you need to immediately begin to fight with insecticides. At the same time, regular inspections will allow you to detect pests at the earliest stages, because aphids, scale insects, spider mites in a radermacher lead to a rapid yellowing of leaves and young shoots, by which it is easy to judge the appearance of problems.

But diseases, with the exception of rot with waterlogging, are practically not found in the emerald tree.

Common growing problems:

falling and yellowing of leaves with excessive shading;
leaves become soft, droop, loses rigidity, become translucent or too pale during drought or excessive waterlogging;
shoots are pulled out in low light;
leaf tips dry out in excessive light or in extremely dry air combined with insufficient substrate moisture;
the plant produces too small and dull leaves with insufficient feeding or in the shade;
weak, thinned shoots develop with too scarce fertilizers.

Indoor flowers Radermacher Chinese and other types with photo

Indoor flowers are available for sale in a wide variety of varieties. On sale and among the owners of indoor plants, only one species of this genus has become widespread - the Chinese radermacher. It is a small and fast-growing tree up to 1 meter in height. Numerous spreading and slightly drooping branches, strewn with small glossy leaves, extend from the erect trunk from the very bottom. It is the leaves that add decorativeness to the radermacher and emphasize the beauty of the plant. Small (3-4 cm in length), smooth, double-feathery, with two or three denticles along the edge, they form a beautiful lush crown. The color of the leaves is green or dark green, but variegated species are also occasionally found. Veins are clearly visible on the shiny leaf plate.

See what a Chinese radermaker looks like in a photo illustrating all the attractive properties of a shrub:

Also known as indoor ash. There are other types of radermaker that allow you to create bright compositions in the aggregate.

Fiery (ignea) - in its homeland in Laos and in northern Thailand, a 20-meter tree is distinguished by a sparse crown, evergreen or semi-deciduous. The leaves, like the previous species, are glossy, dark green in color, but the flowers look unforgettable: bright fiery or deep orange, usually decorating old branches or clinging directly to the trunk. Forms fruits in the form of elongated narrow capsules, curled up, splitting, about 45 cm in length.

Types and varieties

In the wild, only 17 species can be found
Radmakers, while not all of them are widespread in the culture.

Radermachera giant (Radermachera gigantea)

The dense, glossy foliage is leathery to the touch. During
flowering, dense paniculate inflorescences are formed, consisting of large
pinkish flowers.

Radermachera woody (Radermachera xelocarpa)

This upright tree has one trunk and is
reaches from 5 to 10 meters. The foliage is rich green, and the flowers are cream,
snow white or pale yellow hue.

Radermachera Chinese, or Sinica (Radermachera sinica)

This type is the most common in culture. Such
strongly branching shrub reaches a height of one and a half meters and has a straight
trunk. The dark green foliage is quite large, there are variegated forms.

Radermachera ignea fiery red (Radermachera ignea)

The height of the spreading tree is about 7 meters. The foliage is oval-oblong. Orange-red bright flowers cover the whole plant.

Reproduction methods

At home, the radermacher is most often propagated
layering and cuttings. It is much more difficult to grow it from seeds.

Reproduction by layering

Choose one strong shoot and make on its bark
a two-centimeter long incision, which should be located longitudinally. At first
a layer of wet sphagnum is laid on it, then wrapped with cling film and
fix all this with a fairly wide strip of fabric. Make sure that
the moss was constantly a little damp, it is taken well to moisturize it
settled water. After the formation of its own roots, the layers are cut off and planted
into a new pot. To make him start better, he is treated with a solution of the product,
stimulating growth.

Cuttings

The harvesting of apical cuttings is carried out in the last days.
spring or in the first - summer. Their length can vary from 70 to 100 mm. Root
them in a mixture of sand and peat, covered with a film on top. Provide them with enough
a lot of light without direct rays of the sun and warmth (from 23 to 25
degrees). Keep the substrate moist and after just 6-8 weeks
cuttings will give roots.

Seed reproduction

The seeds of the radermachers are sown in a pre-disinfected and
a substrate of sand and peat moistened with warm water (1: 1). They are slightly pressed
into the soil mixture and sprinkle with a thin layer of river sand. Top cover
film and put away in a well-lit (diffused light) and warm (22-25
degrees) place, while the crops are provided with bottom heating.

Seedlings should appear after 1-1.5 weeks. Still after
the same period of time is spent picking them in individual pots with
peat and sand.

Growing indoors

Illumination

A room ranger grows best in bright, but
diffused light. However, she will feel quite comfortable in
slight shading. It is better to choose a western or eastern window sill for the bush.
Also, in the summertime, it can be placed on the north window. And here is the windowsill
south orientation is not suitable for such a culture. But if you still go there
put the plant, then do not forget to shade its foliage from scorching
sun rays.

Please note that the flower needs a lot
light at any time of the year

This is especially important in winter, because due to excessive
poor lighting, the bush can begin to actively stretch out, which is negative
will affect its decorative effect. Also don't forget to systematically little by little
turn the tree around its axis so that it does not grow one-sided

Also don't forget to systematically little by little
turn the tree around its axis so that it does not grow one-sided.

Temperature regime

During the growing season, he should provide a moderate
air temperature (from 20 to 25 degrees). In winter, they must endure it.
to a cooler place, while the temperature should be from 14 to 18
degrees. The room where the bush is located must be systematically ventilated.
But at the same time, protect it from drafts.

Watering rules

In the spring-summer period, the radermacher needs abundant
watering. It is carried out immediately after the top layer of the soil mixture dries out in
pot. Remember that for this culture, it is equally harmful as stagnant fluid in
roots, and overdrying an earthen coma.

With the onset of autumn, watering is reduced, and in winter
time, the substrate is moistened only when a couple of days have passed after
drying out its top layer. For watering, use only well-settled
and always soft water.

Optimum humidity level

Radermacher is a moisture-loving plant, therefore, in the room,
where it is located, the humidity should be increased. To do this, you can in
add a little expanded clay or pebbles to the pallet, pour in a small amount of water and
put a pot with a tree on top. It is also recommended systematically
moisten the greens of the plant from the spray bottle, using the settled
water, the temperature of which is close to room temperature. In the summertime, the bush can
arrange a warm shower.

Fertilizer

From the second half of the spring to the end of summer
the plant is fed with a complex mineral fertilizer with a frequency of 1
every 15–20 days. To prepare a nutrient solution in a liter of water
dissolve from 1 to 2 grams of fertilizer. In winter, the bush is not fed
only if it is in a cool place (the temperature is not higher
20 degrees).

How to transplant correctly

While the bush is young, it is transplanted every year. Wherein
adults and old specimens are subjected to this procedure once every 2 or 3 years.
The transplant is carried out in the spring, while you need to adhere to the following
plan:

The new pot should be 2-3 cm in diameter
bigger than the old one. A drainage layer with a thickness of 30 to 40 mm is laid out at its bottom.
To do this, you can use pebbles, expanded clay or brick chips.
The drainage is covered with a thin layer of prepared
advance soil mixture

To prepare it, you need to combine peat, leaf and
sod soil, and also garden humus (1: 2: 1: 1).
Carefully pull the radermaker out of the old pot
and trim overly long spines if necessary. Transplant
it is recommended to carry out by transshipment method.
Place the tree in a new pot and fill everything
emptiness with fresh earth mixture

Tamp its surface a little near the stem.
Immediately after transplanting, pinch the upper
parts of the stems. Then gently water the plant while pouring the water gently
along the edge of the container.

The transplanted bush is transferred to a shaded area for several days.
place and at the same time do not forget to systematically moisten it with well-settled
lukewarm water.
