Indicator of Healthy Growth
Moderate growth of aerial roots indicates that the plant is in an active state, capable of absorbing water and oxygen through the surface of the roots. If aerial roots are completely absent, it might suggest insufficient environmental humidity or poor nutrition in the plant.

Choosing the Right Time for Pruning
It is recommended to perform the operation during the spring and autumn growing seasons when the plant has a strong recovery ability. Use a sharp garden剪 that has been disinfected with alcohol to avoid tearing the root and stem tissue.
