1、 What if the seedlings are weak

1. Scientific soil matching: when planting weak orchid seedlings, we must choose appropriate planting materials. Because the root system of weak seedlings is very weak, it must be planted with plants with good permeability. In addition, it is best to choose plants containing orchid bacteria. Because they can help orchids absorb nutrients and help them grow better

2. Proper shading: orchids like shade, and their weak seedlings can't withstand strong light. Therefore, when maintaining weak seedlings, it must be cultured in a semi shady place to avoid direct exposure to strong light

3. Water and fertilizer control: when raising weak seedlings, avoid large water and fertilizer. The frequency of watering and fertilization must be strictly controlled. Do not water unless the soil is dry. Do not apply fertilizer unless the root system of the plant returns to growth. So as not to cause additional burden on its roots

4. Keep ventilated: when maintaining it, keep ventilated to provide it with fresh air. This can help increase its growth and make it grow stronger faster

2、 Can I raise it with raw sawdust

Sawdust can be used to raise weak orchid seedlings, but it's best not to use sawdust alone to raise orchids. Because of its strong permeability, it is very suitable for the root growth of weak orchid seedlings. However, if only sawdust is used for feeding, the weakness of insufficient nutrients will be highlighted. So it's best to use it with some plant materials with sufficient fertilizer
