Part4 - Light and transplant
Transplanting - Phalaenopsis (Phalaenopsis) should be transplanted every 2-3 years, because by watering and fertilizing the substrate in which the orchid grows, it loses all its beneficial properties for the plant. Irrigation increases the overall pH, and the bark decomposes and loses its oxygen conduction. In addition, fertilizer residues accumulate and in turn increase the salinity of the soil layer.
The most appropriate time for transplanting is the period of new growth of the plant when the orchid builds new roots. The transplantation of Phalaenopsis with forthcoming flowering is not recommended, as this is very likely to delay the flowering of buds and the budding of the undissolved buds. It is advisable to choose plastic pots because clay absorbs moisture and this makes it difficult to water. For beginners, the use of transparent pots is best - it helps to monitor the condition of the root system and to avoid errors more easily.


Orchid care - light and transplant
Light - Having enough light is one of the main factors that determine the normal development and regular flowering of Phalaenopsis. Since there are too many hybrid representatives of this genus, no general rule can be drawn. Depending on the latitude, the orchid may receive less than necessary light in winter and more in summer. Generally, windows with east to southeast orientation are most suitable, where direct sunlight can only reach the plant in the morning, when the sun is still weak.
In the south and southwest windows the intensity of the sun's rays is much higher. The good thing about this presentation is that Phalaenopsis blooms much more frequently. It also grows more compact, with smaller and rounded leaves, but there are some downsides to the downside, which are also dangerous. Direct and prolonged sunlight can cause the plant to heat up to 32 ° C and burn.
Depending on the intensity of direct sunlight, different degrees of burns are also distinguished. In the initial stage of exposure, the plants have a slightly yellowish tinge or lighter (often white) areas appear on their leaves. In severe burns of the leaf tissue, it dries. It often turns black with white sunken spots, but another manifestation is possible. In order to protect the plant from overheating, in hot months the orchid must be placed behind a curtain or in the shade of other plants.

North windows are considered the worst growing option because sunlight is insufficient. As a rule, in such an exhibition orchids grow slowly and rarely bloom. However, if this is the exhibition, in addition to natural light, it is recommended to use artificial phyto or aquarium and terrarium lamps. It is advisable to use every day from 18: 00 to 22: 00 hours.
Combination illumination of orchids is considered to be the most effective. In the autumn and winter period, keep in the west and south exposure, and in the spring and summer in the east and light northern windows.
