The reason for the black root of orchids

There are roughly these reasons, hypertrophy, large water, plant material is not mature or airtight. There are many reasons for poor ventilation, sometimes it is poor plant permeability, sometimes black plastic basin absorbs heat, you bask in the basin in summer, the basin is too muggy, or watering at high temperature, watering impenetrably may cause crystal head carbonation.

When growing new roots, the plant material is too dry, the fertilizer is too heavy, and the plant material is dry, wet, uneven and airtight.

Solution:

1. It is better to have a soybean-sized gold plant near Lutou.

2. The plant material should be matched with the environment. If the environment is relatively dry, the plant material should be softer.

3. when potting, the planting material should be evenly spread, and there should not be too many gaps.

4. if the plant material is pulverized seriously for a long time, if the new plant material is replaced in time, the varieties with more roots can be softer, such as cymbidium, lotus petal, etc., and those with few roots, such as Jianlan, Chunlan can be harder.
