What plants are used for orchid cultivation on balcony

The balcony raises the orchid to have no land to use, must have the orchid basin and the plant material, this is the most basic condition. Now there are many kinds of orchid pots on the market, and what I use most is mud pots. This kind of orchid basin has good air permeability and fast water evaporation, which is beneficial to the root. The second is the plastic basin, which has the advantages of small size, small footprint, clean and beautiful, but poor air permeability. If it is watered too much, it is easy to cause mildew. Also use a small amount of purple sand basin, its characteristics are similar to plastic basin, beautiful and practical, the first choice is those with holes in the basin wall. The plant material I used more is Emei Immortal soil, which has good aggregate structure and strong air permeability, which is beneficial to rooting. But it is very easy to dry, so it should be soaked in water for three or four days before use and let the water permeate before it can be put on the basin. In the future, I will also use the humus soil on the mountain, which is loose and contains more organic matter and nutrients, as well as good water and fertilizer conservation properties, which is conducive to the growth of orchids. But it has to be screened twice. First sift out the fine soil in the form of powder, and then divide it into coarse particles and small particles, which are used in the lower part of the orchid basin and the upper part of the orchid basin. They should be exposed to the sun or sterilized at high temperature before use. There are also some red brick grains and Tangji blue stone, which are used as the medium of the above two kinds of plant materials, accounting for 1/4 to 1/5 respectively. Orchid pots and plant materials should be matched scientifically, and plastic pots and purple sand pots with good water retention should be mixed with red brick grains with good permeability of Emei immortal soil. The mud basin with good permeability can be mixed with humus with strong performance of water and fertilizer conservation. Only in this way can we give full play to their strengths and avoid weaknesses and give full play to their respective advantages.
