Ascocentrum

Ascocentrum

Ascocentrum (Ascocentrum) is a flower from the orchid family. There are from 6 to 13 representatives in the genus, which have the properties of both lithophytes and epiphytes. Natural plantings of the ascocentrum orchid are found in the Philippine Islands and in Asia.

Description of the orchid ascocentrum

The plant is characterized by a monopodial type of growth, which implies the presence of one unbranched stem. The main stem continues to grow in size continuously until the flower dies. Root air layers have a thickened structure and lie close to the surface. The rhizome is covered with velamen - a white porous bloom with a silvery tinge.

The curved greenish-red foliage is arranged in two rows in succession. Vaginal leaves are in close contact with the shoot. The belt-like plates are firm to the touch. Intermittent barbs are present at the ends. Their number, as a rule, does not exceed 1-3 pcs. The leaves grow no more than 2 cm wide, and sometimes up to 30 cm long.

Ascocentrum bloom is observed in spring or late summer. At this time, in the lower part of the plant, short peduncles arise in the axils. In different species, the height of the arrows reaches 8-20 cm. Strong cylindrical inflorescences, consisting of several buds, sit on the peduncles.

Small flowers - about 1.5-2.5 cm. The calyx frame is formed from 3 oval sepals. Inflorescences are called zygomorphic. The buds are in the same position relative to each other. The opening angle is 120 degrees. Sepals and petals are slightly different in color.

If you look closely at the two opposite petals, you will find that they are also 120 degrees apart from each other, so the rim has the correct shape.

In addition to the sepals, the flower consists of a narrow three-lobed lip of modest size. The end of the lip is pushed forward, and the two processes located on the side stick out vertically. Behind the lip, a long outgrowth or spur completes. Fresh nectar is collected in the hollow interior. Thanks to this feature, the plant got its botanical name "ascos" and "kentron", which translated from Greek means "bag" and "spur".

Types and varieties of ascocentrum with photo

Modified varieties of Orchidi Ascocentrum have a pronounced similarity to each other. Differences are observed only in the size and color of the inflorescences.

  • Dwarf - the longest shoots grow up to 4-6 cm, flowers are painted in pink;
  • Christenson - the bushes reach up to 40 cm in length, the plant blooms with pink-white buds;
  • Curved - the height of the peduncles is 15-25 cm, the flowers are orange, red or yellow;
  • Miniatum is an orchid 10-20 cm high with orange or red inflorescences;
  • Bubble - a low-growing variety, which is characterized by red or purple flowers.

Ascocentrum orchid care at home

The described genus of orchids is one of the most capricious and fastidious plants. Indoor varieties of Ascocentrum will have to pay a lot of attention after planting. Only an experienced florist can handle their cultivation. However, today, thanks to the labors of breeders, various hybrids have been bred, therefore, caring for ascocentrum at home has become much easier.

Location and lighting

The flower prefers to grow in a well-lit place where bright diffused light will fall on the leaves. It is not recommended to leave the flowerpot in direct sunlight for a long time; it is better to accustom the plant to the sun gradually. Ascocentrum orchid develops stably on window sills near windows directed to the east or west side.

With the arrival of autumn cold weather and for the winter period, additional lamps are installed near the ascocentrum. It is important to observe the light regime, i.e. during the year, the duration of daylight hours should be 10-12 hours. Otherwise, the lack of light will lead to a stop in growth.

Temperature

The orchid needs daily temperature changes so that the difference between night and day temperatures is at least 10 ° C. Optimal conditions are when the thermometer in the room is in the range of 24-31 ° C during the day, and at 10-20 ° C at night. Such a regime will have a beneficial effect on the cultivation of culture at home.

It is not recommended to take the pot with ascocentrum outside in the heat, since changes associated with adaptation to a new habitat can cause severe stress in the flower, which in turn will provoke the appearance of diseases and rapid wilting.

The soil

For growing Ascocentrum orchids, special hanging baskets or blocks are selected where no substrate is used. The aerial root system needs oxygen and good lighting. In some cases, an ordinary piece of pine bark is selected as a block. The rhizome is fixed on top of the block, wrapping each root with a thin layer of moss or coconut fiber to prevent moisture evaporation after watering.

Low-growing varieties and young seedlings are allowed to be planted in flower pots made of transparent material and filled with chopped pine bark. This natural raw material supports the shoots and helps to maintain balance. After watering, the roots dry out much more slowly, since the bark retains moisture.

Watering

For the ascocentrum orchid, a dormant period is not provided, in this regard, watering is organized to the same extent throughout the year. The rhizome is watered by immersing a flowerpot or block in a bowl of water. It is allowed to submerge the plant completely, it will not harm it. After 15-20 minutes, the orchid is taken out of the water and returned to the place where the pot stood before. In a similar way, growers are advised to water the flower every day.

Air humidity

In order for the plant to develop normally, high humidity is maintained in the room - from 80 to 90%. Humidity below 70% negatively affects the growth of the Ascocentrum orchid. The microclimate in apartments, especially at the height of the heating season, does not always correspond to optimal standards. To get out of the situation and increase the humidity, household humidifiers or steam generators help.

Top dressing

It is enough to fertilize the plant once a month. Special mixtures are used for orchid crops. It is advisable to take half of the dose indicated by the manufacturer on the label. Top dressing is dissolved in irrigation water. It is also recommended to arrange monthly foliar feeding of the ground part when the leaves are sprayed with the diluted nutrient mixture.

Diseases and pests

Diseases and pests will bypass the ascocentrum side if you follow proper flower care. Deviation from the temperature regime, lack or, conversely, excess of light, errors in watering, dry air in the room, neglect of the temperature difference between day and night are the main reasons that slow down the development or lead to the death of the plant in the future.

How to plant orchids by dividing, grafting and using "children"

Every orchid lover will tell you that this is the most beautiful and expensive flower. But, besides this, it requires special care, and any florist wants to multiply his pet in order to get several new bushes.

How to plant orchids by dividing

This method is one of the simplest methods of propagation, which is used for plants growing sympodially. The division method is suitable for plants such as cymbidium, cattleya, lelia, dendrobium, oncidium, and so on. These flowers have several points of growth, and each such bore gradually thickens and becomes a pseudobulb, which means that the plant can be propagated. But the main condition is the presence of several shoots. The plant must be divided so that on each part there are 2-3 pseudobulbs. In this way, the orchid is best propagated in early spring. First, you need to carefully clean the rhizome from the substrate and cut the flower into several parts with shears. Treat each cut with wood powder. Plant all plant fragments in pre-prepared pots, spray them daily and water them from time to time. With the emergence of new shoots, we can say that the orchid has taken root.

This method should be used to propagate plants with monopodial growth. Such orchids include vanda, phalaenopsis, vanilla, brassavola, vandopsis, ascocentrum, angrekum, aeridis. These species do not have pseudobulbs, they only have one growth point. A lateral shoot or a faded flower stem is cut off from the plant, then they must be placed on the surface of the soil. To do this, use plain sand or sphagnum moss. Then you put everything in a greenhouse for rooting.

How to plant orchids using "kids"

"Babies" are lateral shoots, which are already small plants in themselves. But this method of reproduction is available only to a few species of dendrobium and phalaenopsis. And "babies" appear only if the orchids are in a room with a sufficiently high temperature. You can stimulate the appearance of "children" in the plant, for this it should be fed with a fertilizer with a high nitrogen content.

Of course, all of the above orchid propagation methods are good, but this way you only get the species you already have. But you want variety, besides, the orchid is an excellent gift. Flowers from the bouquet will wither anyway, and your gift will delight the hostess for more than one year. Therefore, it is worth trying to grow orchids from seeds. Take a pot, fill it with chopped sphagnum, moisten well and sow seeds on top, you do not need to sprinkle them. Then place the pot in a greenhouse bag, the temperature should be 23-25 ​​° C. As the surface dries, it should be sprayed with warm water. As soon as leaves appear on the seedlings, they are dived into a bowl with a mixture of chopped peat and moss. When four leaves appear on the plant, it should be transplanted into a separate pot.

Orchid leaves turn yellow for reasons

The yellowness can be caused by natural wilting of the leaf. As a rule, the leaf itself gradually turns yellow and dries. This happens in a couple of months without touching the rest of the leaves. There is also a rapid yellowing, leaf fall during rest (for example, in dendrobiums).

In an orchid, the leaves obey their own life cycle, which can last 5 years in some species, 2-3 years in others, and only a year in others. Some varieties, once every 1-2 years, can completely or half throw off the leaves on mature buds. In a monopodial orchid (Phalaenopsis), 1-2 leaves from below naturally die off. In sympodial plants (Dendrobium), the leaves are shed annually or twice a year, both during and after flowering.

In Dendrobium, the leaf lifespan is short, about 6-18 months; in some species, the leaves turn yellow gradually during the dormant period. This is natural and normal.

Kalantha throws off the leaves before or during rest. At a new stage of development, the leaves grow again.

Tropicanas, on the other hand, preserve leaves for many years.

Poor highlighting can be a common factor in leaf yellowness.

Many plants love good moisture and bright light. Sometimes an orchid germinates in a poorly lit room for 1-2 years and only then weakens, losing leaves.

Orchids with tough leaves love light. These include laelias, cattleyas, and their modifications. In addition, they love the light of Ascocenda, Wanda, Rhynchostilis, Ascocentrum, Angrekum. They have leathery leaves.

If the leaves of an orchid are delicate, light green in color, they quickly begin to turn yellow, burn in the sun, therefore, they need to be placed in the shade. These include Miltoniopsis, papiopedilums, shoes, which have a pattern in the form of spots on the leaves.

Yellowed leaves can become rough due to prolonged exposure of the flower to bright sunlight. The leaves of the plant overheat, tissue decay occurs.

The second reason for the yellowness of orchid leaves is abundant watering with long pauses.

If the flower withers, despite systematic watering, the leaves still turn yellow. Maybe you water the plant too much, or the pot is too tight, the roots are too dense. It is required to make watering regular - do not overfill and overdry the soil. There should be no water on the bottom of the pot, otherwise the roots will rot.

It is necessary to provide that in winter the hot air from the battery dries the roots. The humidity of the air near the orchid also decreases. Then you need to put a plate of water next to it or use a humidifier. Better to put the plant further away from the battery.

Too much fertilizer.

In order for the plant to grow quickly (especially when breeding Phalaenopsis), a lot of fertilizer is added to it. When purchasing a flower, it can look great, and bloom well in the next couple of years, but then the plant is depleted - it quickly turns yellow, loses its leaves. The transplant does not help, but the flower can be saved, it will take time.

The plant is transferred to a bright and warm room. You do not need to do additional feeding at first. After a while, fertilize should be 1 time in 14 days and strongly diluted with water. For the first feeding, use the usual fertilizer that is suitable for orchids, diluting it in half, then nitrogen fertilizer, so that the growth of the leaves increases. In the case when the plant blooms before the appearance of the first pair of leaves, such a blooming of a weak plant may be the last. It happens that only after 2-3 years the flower begins to throw out its leaves. After normalizing the leaf cover, the orchid will bloom again.

In addition, it must be borne in mind that the roots of many plant varieties are sensitive to the influence of various phosphorus, potassium soda contained in fertilizers, and during the application of a large concentration, the flower can be severely damaged.

If the fertilizer is oversaturated, place the container with the flower under warm water and rinse the plant well. If necessary, apply the next dose of fertilizer no earlier than 1-1.5 months, and dilute the fertilizer itself by half with water. Certain plant varieties withstand irrigation with hard water negatively, use filtered water for irrigation and fertilization.
