The reason why it is chosen is because it never builds up moss but absorbs moisture well. However, if the substrate is all fern, there will be no ventilation.

There are 2 types of worms:

  • Spinning yarn: this is an old, filamentous type that is popular for growing orchids in the city.
  • Dumplings: this is the remains of the cypress tree after it has been taken, the fern is the young parts of the vine stem – this is used to grow orchids very well in cold regions because of its high hygroscopicity, but lack of ventilation. air, so the temperature in the pot is usually higher than the outside, so the soil will create a certain amount of moisture, creating favorable conditions for the growth of the roots (if the temperature is high, the humidity is low, it is not recommended to use shredded chicken. ).

There are also some types of molluscs derived from sea moss, which are imported from abroad and are widely used in Vietnam. Soft wormwood has the advantage of keeping moisture very well and is very suitable for the orchid root system to develop. High price, easy to be mossy, waterlogged in the rainy season.

Chopped coconut shell (1x3x2cm) is treated with 5% lime water or 2% NaOH. The disadvantage of coconut shell is that it is not durable, easy to grow algae on the surface.

Coconut shell pieces: If you use whole coconut shells to plant pots, you must limit watering. It is best to create conditions that ensure moisture outside rather than in the pot. Coconut shell pieces are a very good environment for most orchids of the genus Dendrobium. The disadvantage is that it is easy to grow moss, not well ventilated, easy to rot. For this growing medium, regular spraying of insecticides is required.
