We are waiting for the flowering of orchids. They do not cease to amaze.
This vast genus of the tribe of Vandov [3]: 50, has about 70 species [4]. Representatives of the genus - monopodial plants with a strongly shortened stem and wide leathery leaves. The plant grows only in one direction - upwards. From the sinuses between the leaves the plant releases air roots and peduncles. In an adult plant, usually 4-6 leaves.
Leaves are evergreen, 5-30 cm long. Some species have beautiful marble pattern on leaves.
Peduncles axillary, long, often branching, in many species with a large number of fairly large flowers. The flower resembles the shape of a butterfly [3]: 50.
Roots air with a thick layer of velamen, sometimes flattened, in some species greenish due to the presence of chlorophyll in them.
Species having fragrant flowers: Phalaenopsis amabilis, Phalaenopsis bellina (the strongest and most pleasant aroma compared to other species of the genus), Phalaenopsis corningiana, Phalaenopsis gigantea (faint, sweetish flavor), Phalaenopsis lueddemanniana (strong, pleasant aroma), Phalaenopsis mannii, Phalaenopsis mariae (faint aroma), Phalaenopsis modesta, Phalaenopsis pulchra, Phalaenopsis reichenbachiana (musty smell), Phalaenopsis schilleriana (the fragrance appears in the last weeks of flowering), Phalaenopsis speciosa, Phalaenopsis stuartiana (weak flavor), Phalaenopsis sumatrana, Phalaenopsis tetraspsis (strong flavor), Phalaenopsis venosa (unpleasant odor), Phalaenopsis violacea, Phalaenopsis wilsonii [5].
Systematic [edit] edit wiki-text]
In the room, phalaenopsis is grown either in plastic pots (often transparent), or by block culture method [7]. Transparent plastic pots are used to control the moisture of the substrate and the state of the root system.
Most of the species and hybrid phalaenopsis can be kept at a relative humidity of 40-50% [8]. There are many described cases of successful growing of powerful epiphytic plants in the conditions of an ordinary apartment, without spraying. It should be ensured that water does not fall into the axils of the leaves: this can cause decay [9].
Most species and hybrids belong to a warm temperature group. In winter and summer for them, the temperature is 22-25 ° C, at night - not lower than 21 ° C [3]: 50. For successful flowering, a difference between day and night temperatures of 5-10 ° C is desirable [10].
Most phalaenopsis plants are plants without a clearly expressed period of rest, therefore, throughout the year, watering should be moderate, but regular. Water is used for irrigation (preferably soft or purified by reverse osmosis) at room temperature.
Almost all phalaenopsis are epiphytic plants, in natural conditions they grow on trunks and branches of trees. Moisture, mineral and organic substances they provide numerous photosynthetic air roots, which they are attached to the bark of trees and plant residues accumulating in the branches of branches. Therefore, in the room and greenhouse culture, the roots of these plants need air circulation [11].
As a drainage to the bottom of the pot, you can pour claydite or pieces of foam. Substrate for planting is prepared from a mixture of large pieces of pine bark.
Fertilizing with a special fertilizer for orchids or complex mineral fertilizers is carried out once a week or two.
The transplant is performed once a year after flowering [9].
There is a successful experience of resuscitation phalaenopsis, lost roots.
