1、 Can the newly bought culture soil be directly used to grow orchids

Generally speaking, if it is a professional cultivation soil with packaging, it can be directly used to grow orchids. Because this kind of soil is packaged and sold after sterilization, it will not contain bacteria. However, if you buy back bulk culture soil, it's best to use it after disinfection. This can prevent the original bacteria in the soil from infecting the orchid strain and causing it to get sick

2、 How to deal with the newly bought soil for planting orchids

1. Sterilization and disinfection: in order to prevent the bacteria in the culture soil from infecting the orchid strain and making it sick, it should be sterilized and disinfected before using the new soil. The commonly used method of disinfection is sun exposure. Spread out the new orchid soil in a place with direct sunlight and expose it to the sun for a day. If it is inconvenient, you can also put the orchid soil into an iron pot and heat it to stir fry. This can also eliminate germs and pests

2. Prepare the pot: if you buy professional orchid culture soil, you can put it directly into the pot. But if you buy bulk soil, you have to prepare it. The preparation method shall be determined according to the variety of orchids raised. If you want to cultivate orchids, you can prepare them with garden soil, peat soil, rotten leaf soil, river sand and other soil. If you want to raise epiphytic orchids, you can prepare them with rotten bark, pine needles, crushed stones, seaweed and other substances
