Features of growing orchids in pots

In pots they grow calenda, tunia, pleione, faience, flea, and all kinds of orchids that do not like the complete drying of the soil. If epiphytic species are planted in pots, then only special flowerpots for orchids with numerous holes or baskets are chosen for them. For other species, relatively more “standard” containers are acceptable.

Special containers for orchids – transparent, with numerous openings for breathing roots, most often double with a more decorative and solid “bowl” on top – can be found on the shelves of any flower shop. But orchids are grown not only in such containers. They can be planted in ordinary baskets, ceramic and even plastic containers, although each time the choice of a non-special container is akin to a lottery:

Moisture is best stored in plastic pots, but baskets provide the best conditions for plant respiration.
Baskets are an alternative to growing on blocks for epiphytic species of orchids – those plants that naturally settle on branches and stumps, especially with peduncles hanging down. Orchid baskets are well ventilated. They come in different sizes and diameters (from 10 to 25 cm) and are made of different materials. The most popular option is a tree or a vine.
For orchids from among ceramic containers, glazed models are considered optimal. Clay and porous containers are not suitable for indoor culture. Orchids are planted in them only in flower farms, greenhouses or greenhouses, where the problem of moisture evaporation by porous materials is compensated by stably high humidity. In any clay containers for orchids, numerous ventilation holes (diameter – about 0.6-0.7 cm) on the bottom and walls should be made.
The choice of pots has its own limitations:

if photosynthesis in the roots occurs in an orchid, then only transparent glass and plastic vessels can be chosen (for example, phalaenopsis is grown in such containers);
for all epiphytes, only growth options in special baskets suitable for free access of air to the roots are suitable;
the dimensions of the container are always taken in accordance with the dimensions of the plant itself;
Orchid often “grows” to natural materials, which complicates transplantation.
The optimal ratio of the width and height of the pots for orchids is a slightly elongated shape with an extension upward, the height is 10-20% more than the diameter. The containers are selected so that the roots of the plant touch the edges of the pot, they were not too spacious or cramped.

At the bottom of such tanks, a high drainage, of about 1/3 of the tank height, must be laid from shards, expanded clay, in extreme cases, from synthetic materials.

The difficulties in growing orchids in a substrate are not limited to the choice of type of capacity. Orchids need a special substrate. Despite the fact that in the line of each manufacturer of earth mixtures there is a special offer for orchids, they differ in terms of moisture capacity, quality and composition.

For normal development, the absence of rot, respiration, the substrate should have sufficient coarseness and consist mainly of light materials – large pieces of bark. In various versions of orchid mixtures, expanded polystyrene, moss, peat and even mineral wool are added to pine and other types of bark. For dendrobiums, miltonia, cymbidiums, shoes, oncidiums, a substrate with 20% water-absorbing additives and a small fraction is chosen, for phalaenopsis – with an average fraction of the cortex. Wands are grown only in large bark.

Potted plants include calendula, tunia, pleione, faience, flea, and all kinds of orchids that do not like the soil to dry completely

Rules for transplanting orchids into a pot
In the process of transplantation, you should be careful and carefully treat the plant:

First, a container is prepared by making holes in the center and on the walls, if necessary. For clay pots, it is advisable to attach a rigid wire frame to which the plant will cling. For orchids, they prepare a support for fixing – a light natural peg.
The orchid is carefully removed from the old container. In specialized stores there is a special tool, but you can also act manually. The roots should not get any injuries.
Old soil is completely removed from the roots, if possible.
The plant is inspected and carefully removed all damaged, dead or rotted areas of the roots.
At the bottom of the pot lay drainage if not special containers are used. A special plastic mesh is placed at the bottom of the baskets, which will prevent the substrate from waking up in the holes.
Holding the orchid in his hand, it is set so that the base of the plant, the junction of the roots remain at the level of the upper edge of the container. The base of the pseudobulb should be 1-2 cm below the wall level. If a wire frame was made, a plant is fixed on it.
The container is filled with a substrate so that the rhizome remains…
