1、 How about raising orchids all with granular soil

It's not good to cultivate orchids all with granular soil. Although the permeability and drainage of granular soil are very good, the content of nutrients is too low to meet the needs of orchid growth. If it is kept in pure granular soil for a long time and is not fertilized in time, it will appear yellow leaves due to lack of nutrients. If it lacks nutrients for a long time, it will dry up and die

2、 What kind of soil is good for raising orchids

When culturing orchids with granular soil, you can add some rotten leaf soil or base fertilizer to the soil to increase the fertility of granular soil. In this way, the nutrients contained in it will increase, and the orchid can also absorb enough nutrients from it, and then grow normally. During maintenance, pay attention to changing the soil for it every 1-2 years to ensure that sufficient nutrients are used in the soil to meet its growth needs

3、 Can peat soil grow orchids

泥炭土是一种养分含量很高，并且透气性也相对较好的土壤，用于种植orchid是比较合适的。只不过，最好不要只用泥炭土来种植orchid，更加建议将泥炭土和菜园土以及河沙混合起来配制orchid的培养土。这样配成的土具有更好的排水和透气能力，对兰株根系的生长更加有利。
